Specifically, the study focuses on identifying the impact of different consumer freezing methods and product size (steaks vs roast) on beef quality from different muscles.</p><br /> <p><strong>California &ndash; Timothy J. Hackmann and Payam Vahmani</strong></p><br /> <p>Our research has focused on three main areas: 1) identifying rumen bacteria responsible for the presence of specific trans fatty acids in beef fat, 2) investigating the role of different rumen-derived trans fatty acids on marbling fat synthesis using primary intramuscular fat cell culture models, 3) assessing health effects of rumen-derived trans fatty acids in mouse models of obesity and type-2 diabetes. Our research projects directly contributed to project objective 5. The outcomes provide a better understanding of the origin of trans fats in beef, and their effects on beef quality and healthfulness.&nbsp;&nbsp;</p><br /> <p><strong>California - James W. Oltjen</strong></p><br /> <p>Between the influence of the &ldquo;food elite&rdquo; on social media and increasing public concerns over climate change, consumer demand for grass-fed beef has increased considerably. Although many consumers perceive grass-fed beef as more environmentally friendly than grain-fed beef, there is a dearth of research available to address these consumer claims. In order to answer both consumer and producer concerns, we performed an experiment that evaluated the environmental footprint (i.e., water, land, greenhouse gasses, and energy), beef quality, and economic out&shy;come of four beef cattle production systems on the West coast. The four systems included conventional beef finished on grain for 128 d, steers grass-fed for 20 mo, steers grass-fed for 20-mo with a 45-d grain finish, and steers grass-fed for 25 mo.&nbsp; We evaluated the shelf life and sensory properties of steaks which has implications for marketing this type of beef.</p><br /> <p><strong>California - Xiang Yang and Pedro Carvalho</strong></p><br /> <p>Antimicrobial resistance (AR) is a significant emerging health issue globally and in the U.S. With respect to the U.S., approximately 2.8 million clinical infections and 35,000 human deaths occur annually. In addition to clinical burdens, the estimated annual economic cost of AR is $21,832 per case which results in over $3 trillion in GDP loss due to excess health care and loss of productivity. Due to the wide use of antibiotics in livestock operations, there is substantial concern that antibiotic use in animal agriculture contributes to AR in humans and leads to threats to public health. Antibiotics have been incorporated into cattle diets to prevent the spread of disease and promote animal health and growth for a long time. However, The use of in-feed antibiotics for production purposes in the livestock and poultry industry is completely banned in the U.S. in 2017 to mitigate the risk of AR. It is important for the cattle producers to find antibiotic alternatives to maintain the health of the animals without promoting AR in livestock production and to understand how different production and/or management practices may influence risk of AR. Therefore, we proposed to assess the effect of antibiotic alternatives on animal performance and health, as well as to characterize and compare the fecal resistome of cattle fed with antibiotics and antibiotic alternatives to assess the effect of antibiotic alternative on the degree of AR in beef cattle.</p><br /> <p><strong>Texas - Miller</strong></p><br /> <p>Research to further understand the connections between beef descriptive flavor and texture attributes and consumer preferences has continued.&nbsp; While positive and negative flavor attributes have been defined in the past, understanding the interrelationships between flavor, juiciness and tenderness have been implemented.&nbsp; Research examining consumer mouth behaviors and the subsequent effect on consumer preferences was also implemented.</p><br /> <p><strong>Texas - Osburn</strong></p><br /> <p>&nbsp;</p><br /> <p>Research activities focused on investigating the development of an amino acid based alternative curing system for processed meat products (USDA-AFRI- 2021-09606).&nbsp; Findings indicate that activation of the endothelial nitric oxide synthase (eNOS) system by addition of the amino acid L-arginine followed by subsequent thermal processing results in the generation of nitric oxide by the enzyme system. For L-arginine treated beef samples, nitrosohemochromogen (cured pigment) and residual nitrite values were lower than conventionally cured (sodium nitrite) beef samples, but still generated observable cured pink color.&nbsp; Concentrations from 1000-4000 ppm of L-arginine are appropriate to generate the desired cured meat reaction in beef samples.</p><br /> <p><strong>Colorado - Mahesh Nair and Keith Belk</strong></p><br /> <p>Colorado State University (CSU) has been actively engaged in several research projects during the past year focusing on palatability, processing, marketing of beef, prevention of food-borne illness, and consumer preferences for beef. Research was also undertaken to evaluate the effects of lipid peroxidation products such as&nbsp; malondialdehyde (MDA), hexenal, and 4-hydroxynonenal (HNE), on calpain-1 function.</p><br /> <p><strong>Oklahoma - Mafi</strong></p><br /> <p>Oklahoma State University has conducted several projects in the past year evaluating beef shelf-life, palatability, cause and improvement of dark-cutting beef and consumer preferences. <strong>&nbsp;</strong>Research evaluated different oxygen scavengers combined with different dark storage temperatures to determine ideal combinations for most extended shelf-life. Also, research was conducted to better understand freezing temperatures in combination with aging times to maximize palatability.</p><br /> <p><strong>Idaho &ndash; Phil Bass and Michael Colle </strong></p><br /> <p>Beef meat science faculty efforts at the University of Idaho have been conducting research through the past year with focus on beef carcass quality, tenderness, color, and dry aging.&nbsp; Focus has been on heavy weight carcasses and the effect of those carcasses on the merchandising of beef round cuts.&nbsp; Research has been conducted on beef chuck rolls and short ribs with the introduction of rosemary extract and acerola cherry powder in combination with one another as topical antioxidants to improve color stability in a retail setting.&nbsp; Research into commercial dry aged beef facilities were investigated for palatability differences and metabolomics. Lastly, various beef cuts were evaluated for use in finger steaks in order to add value to undervalued cuts.</p><br /> <p><strong>Indiana - Brad Kim</strong></p><br /> <p>Dr. Brad Kim at Purdue University has been working on determining the impacts of post-harvest processing factors (developing &ldquo;Smart Aging&rdquo;, in particular) on meat quality attributes. In this reporting period, Dr.Kim&rsquo;s group worked on several beef projects &ndash; 1) NCBA funded fresh beef tumbling and aged/frozen beef for better quality and 2) continue working on USDA-AFRI grant project - the impacts of extended postmortem aging on color and redox stability of different beef muscles&nbsp;</p><br /> <p><strong>Kansas - Logan Britton</strong></p><br /> <p>Dr. Logan Britton has investigated the relationship between plant-based meat alternatives and regular livestock meat in a consumer choice experiment setting. Specifically, an online basket-based choice experiment was utilized to better simulate a shopping experience for respondents in which they had a income constraint and the ability to select multiple quantities of the products show. The results indicated plant-based meat alternative product has a negative cross-price elasticity of demand with multiple livestock meat products, indicating a complementary relationship.</p><br /> <p><strong>Kansas &ndash; Michael Chao</strong></p><br /> <p>Dr. Michael Chao has been investigating a technique known as accelerated aging (AA) to improve the quality of lower quality beef cuts. This technique has shown to improve beef tenderness through submerging vacuum packaged beef in warm water bath for just a few hours. In addition, he looked at the mechanism behind AA of beef with a specific focus on the enzyme cathepsin. In addition, their team has also evaluated the impact of applying an electrostatic field (EF) on thawing characteristics like thawing speed and purge loss as well as its impact on quality attributes during subsequent aging and retail display of beef.</p><br /> <p><strong>Kansas &ndash; Glynn Tonsor, Ted Schroeder, and Brian Coffey</strong></p><br /> <p>Drs. Tonsor, Schroeder, and Coffey have been investigating multiple aspects of fed cattle and beef marketing.&nbsp; Multiple publications have resulted from this work leading to increased awareness on current marketing issues with implications for U.S. competitiveness.</p><br /> <p><strong>Kentucky &ndash; Surendranath Suman</strong></p><br /> <p>Dr. Surendranath Suman&rsquo;s lab group has been investigating the applied and basic aspects of beef color quality. In this perspective, studies are in progress on the impact of aging on beef color. Additionally, the role of myoglobin posttranslational modifications in beef color stability is being examined. Multiple scientific publications have been published in this area.</p><br /> <p><strong>UConn &ndash; Chaoyu Zhai</strong></p><br /> <p><strong>&nbsp;</strong></p><br /> <p>Meat science faculty at the University of Connecticut have been establishing the research laboratory in the past year. The multistate capacity grant was funded in April 2023 and will start in October 2023. The project will study the interactions between lipid oxidation and muscle proteins, which could elucidate how lipid oxidation affects protein function during muscle-to-meat conversion and improve our understanding of the production of quality beef.</p><br /> <ol start="3"><br /> <li><strong>&nbsp;Short-term Outcomes</strong></li><br /> </ol><br /> <p><strong>&nbsp;</strong></p><br /> <p><strong>Arkansas &ndash; Derico Setyabrata </strong></p><br /> <p>Current results indicated that steak freezing caused excessive discoloration compared to roast freezing. Consumer freezing methods, as expected, generated higher discoloration compared to blast freezer, with refrigerator freezer causing the most discoloration.</p><br /> <p><strong>California &ndash; Timothy J. Hackmann and Payam Vahmani</strong></p><br /> <p>Our project identified three new bacterial groups (<em>Tractidigestivibacter</em>, <em>Sporanaerobacter</em>, <em>Parafannyhessea</em>) as capable of producing trans10,cis12-conjugated linoleic acid (t10,c12-CLA) which is known to have potent antilipogenic properties and may reduce marbling fat accumulation in beef. Using bovine marbling fat cell cultures, we found that fat cells cultured with trans10-18:1, the predominant trans fatty acid in feedlot beef, showed reduced fat accumulation compared to those cultured with trans11-18:1, the predominant trans fatty acid in grass-fed beef.&nbsp; Moreover, t11-18:1, but not t10-18:1 prevented fasting insulinemia in diet-induced obese mice. We have additional mouse model studies planned to better understand the isomer-specific effects of rumen-derived trans fatty acids on glucose homeostasis in diet-induced obese mice models.</p><br /> <p><strong>California - James W. Oltjen</strong></p><br /> <p>The results indicate that steaks in the 20GF group displayed a darker lean and fat color, and a lower oxidation state than those in the 25GF group. However, the feeding system did not have an impact on pH or objective tenderness of beef steaks. In addition, consumers and trained panelist did not detect a difference in taste or flavor between the 20GF or 25GF steaks but expressed a preference for the CON and 45GR steaks, indicating that an increased grazing period may improve the color</p><br /> <p><strong>Texas - Miller</strong></p><br /> <p>Flavor is the main driver of consumer acceptability as long as juiciness and tenderness are acceptable.&nbsp; Tenderness and juiciness are closely aligned to each other for consumer preferences.&nbsp; Consumers like beef with higher levels of fat flavor and grilled flavor components and dislike beef with higher levels of cardboardy, metallic, and liver-like flavors.&nbsp; When segmented into mouth behavior groups, juiciness and tenderness were more important for suckers and smoochers.&nbsp; Chewers like beef with a little bit more fight in it where as crunchers want beef that has an initial crunch, like beef with a grilled crust, and then that breaks down easily with subsequent chewing.&nbsp; These results show that consumers across mouth behaviors respond differently to beef that varies in texture.</p><br /> <p><strong>Texas-Osburn</strong></p><br /> <p>&nbsp;</p><br /> <p>Our research efforts demonstrated the efficacy of activating the endothelial nitric oxide synthase system with the amino L-arginine to generate nitric oxide and residual nitrite, simulating the cured meat reactions found in sodium nitrite cured meat products.</p><br /> <p><strong><br /> Colorado &ndash; Mahesh Nair and Keith Belk</strong></p><br /> <p>&nbsp;Our research demonstrated that lipid oxidation products can influence the functionality of calpain-1 in-vitro by covalent modifications. Tenderness is an important quality attribute that influences consumer eating satisfaction of meat and Calpain-1 significantly contributes to the proteolysis of cytoskeletal and myofibrillar proteins and the postmortem tenderization of meat. Our study is the first to demonstrate that lipid peroxidation products have differential impacts on calpain-1 activity in a concentration-dependent manner in vitro. Incubation with hexenal and 4-hydroxynonenal (HNE) decreased the calpain-1 and the autolysis rate, whereas incubation with malondialdehyde (MDA) slightly increased the calpain-1 activity. These results lay the groundwork for future investigations to understand the mechanistic basis of these differences, including their impacts on calpain activity in postmortem muscle and the development of meat tenderness</p><br /> <p><strong>Oklahoma - Mafi </strong></p><br /> <p>Using multiple scavengers in master bags had no impact on retail shelf-life stability regardless of time in dark storage. Oxygen scavenger efficacy can be influenced by number of trays in a master bag or weight of product but with tray number and product weight being held constant adding additional scavengers did not improve beef color or reduce discoloration.&nbsp;</p><br /> <p><strong>Idaho &ndash; Phil Bass and Michael Colle </strong></p><br /> <p>The deep portion of the top round of larger carcasses takes longer to chill and therefore has a more rapid pH decline.&nbsp; This negatively affects the shelf-life of the top round.&nbsp; Regardless of carcass size, the deep portion of the top round has poorer color stability and is tougher than the superficial portion of the top round.&nbsp; Merchandising research utilizing an online survey has demonstrated distinct willingness to purchase differences between the two cuts. Dry aging microbiome work has demonstrated that the microbiome of molds and bacteria of different commercial dry-aging facilities is indeed different.&nbsp; Differences in environment demonstrate unique dry-aging conditions resulting in distinctly different microbial populations on dry-aged beef.&nbsp; Flavor boldness has also been shown to be different among commercial dry-aging facilities. Rosemary extract and acerola cherry powder are effective antioxidants for extending the color stability of beef chuck rolls and short ribs and has led to follow-up research opportunities.&nbsp;</p><br /> <p>&nbsp;</p><br /> <p><strong>Indiana - Brad Kim</strong></p><br /> <p><strong>&nbsp;</strong></p><br /> <p>The tenderizing action of the tumbler appears to have limited impact on tenderness and other meat quality attributes on loin cuts from high-quality grade beef. However, the impact of steak tumbling on low quality grade beef (USDA Select) was examined for instrumental tenderness determination. WBSF values significantly decreased with increasing tumbling time from 0 min to 20 or 60 min, regardless of aging time. The present study also conducted a development of tumbling prediction models using artificial intelligence (AI) based Machine Learning tools and regression analysis. While more data collection and subsequent data analysis is warranted to improve the accuracy of the AI-based tumbling prediction model, the current study suggested a feasibility of using tumbling models to identify optimal tumbling process regimes for the meat industry application. We also found that increasing postmortem aging has detrimental effects on color stability of muscles such as BF, GM, and IF. In particular, the LL was color stable across all aging durations, while the color stability of the IF was most labile with aging among beef muscles. The results of the current study indicate the need of establishing muscle-specific optimal aging practice considering different color stability of different beef muscles.</p><br /> <p>&nbsp;</p><br /> <p><strong>Kansas - Michael Chao</strong></p><br /> <p>All AA treatments improved tenderness of the samples compared to the control with most exhibited similar tenderness as the 21 days cooler aged treatment. This investigation also revealed AA can enhance cathepsin activity of lower quality beef cuts leading to collagen solubilization and protein degradation. For the EF project, it was found that all EF treatments increased purge loss in the outside cooler location and did not improve thawing speed, with high EF voltage taking the longest to thaw. However, it was found that high EF voltage showed a reduction in WBSF compared to the control, but there was no impact of EF on sarcomere length and myofibrillar protein degradation.</p><br /> <ol start="4"><br /> <li><strong>Outputs</strong></li><br /> </ol><br /> <p><strong>Arkansas &ndash; Derico Setyabrata </strong></p><br /> <p>In the past year 3 abstracts related to beef quality study were published.</p><br /> <p><strong>California &ndash; Timothy J.

Currently training is being provided to several undergraduate students and 1 M.S. students. Several workshops were held related to beef harvesting and quality management.</p><br /> <p><strong>California &ndash; Timothy J. Hackmann and Payam Vahmani</strong></p><br /> <p>We identified three groups bacteria that produce t10,c12-CLA and t10-18:1 by using genomics and biochemical assays. We first searched genomes of 142,000 strains for a gene for linoleate isomerase, which catalyzes the first step of biohydrogenation of linoleic acid. We then biochemically tested three of these strains (<em>Tractidigestivibacter scatoligenes</em> SK9K4, <em>Sporanaerobacter acetigenes</em> Lup33, <em>Parafannyhessea umbonata</em> A2) to determine if they could carry out biohydrogenation of linoleic acid in growing cultures (i.e. forming conjugated linoleic acids and trans 18:1 isomers).</p><br /> <p>We also investigated adipogenic and lipogenic effects of key rumen-derived trans fatty acids&nbsp; (t10,c12-CLA, c9, t11-CLA, t10-18:1, and t11-18:1) on stromovascular fraction (SVF) and dedifferentiated fat (DFAT) cells obtained from beef intramuscular adipose tissue. Confluent SVF and DFAT cells were exposed to media containing adipogenic inducers (dexamethasone, 3-isobutyl-1-methylxanthine) and 0, 5, 10 or 20 &micro;M of trans FA treatments for 6 days followed by Oil Red O staining, fatty acid, qPCR, and GPDH activity assays.</p><br /> <p>Moreover, we determined the effects of beef fat enriched with t11-18:1 and c9,t11-CLA on parameters related to glucose homeostasis and liver health in diet-induced obese (DIO) mice. Thirty-six 8-week-old male C57BL/6 mice were divided into nine cages of similar average body weight (four mice per cage). Each cage was randomly assigned for 18 weeks to either a control low-fat diet, a control high-fat diet containing lard, or an enriched-high fat diet containing beef fat enriched with t11-18:1 and c9,t11-CLA. The enriched beef fat was collected from steers fed a diet containing 75% hay and 25% flaxseed-based concentrate.</p><br /> <p><strong>California - James W. Oltjen</strong></p><br /> <p>We performed an experiment that evaluated the shelf life and sensory properties of four beef cattle production systems on the West coast. The four systems included conventional beef finished on grain for 128 d, steers grass-fed for 20 mo, steers grass-fed for 20-mo with a 45-d grain finish, and steers grass-fed for 25 mo.</p><br /> <p><strong>Colorado &ndash; Mahesh Nair and Keith Belk</strong></p><br /> <p>Currently training is being provided to 6 graduate students and several undergraduate students.

Brief Summary of Minutes

The meeting was called to order by Michael Colle at 2:00 pm Central Time. A welcome and brief announcements were made. Michael Colle announced that he will be stepping down from chair once the final report is submitted.


The administrative report was shared as a ppt with the project members to review on their own time.


Station reports were then shared beginning with Payam Vahmani who shared that a bacterium (Cutibacterium acnes AP1) could contribute to high t10 fatty acid content of beef. Phil Bass discussed alternative fabrication of heavyweight beef carcasses and its effect on meat quality and fiber type. Brad Kim shared information on their freeze-thaw of beef products study as well as long-term aging. Ana Paula Salim (Dr. Suman’s lab) discussed aging influence on color, lipid oxidation, and tenderness of biceps femoris cuts in lamb. Tracey Scheffler visited on her work looking at the variation in tenderness within Bos Indicus cattle with a focus on postpartum metabolism. There are differences in mitochondrial functionalities. Amilton de Mello shared his research on microRNA - they inhibit the translation of proteins. Some microRNAs are specific to beef. Carol Lorenzen has been working on moving the needle at NIFA to include meat in their funding programs. Kerri Gehring along with others on the project discussed the publication status of the beef quality audit. They also took a survey on the freezing the thawing process from different establishments - most had no idea how long it was taking to freeze. Liver abscesses in beef x dairy cattle was also discussed. Gary Sullivan and his team have been looking at using high pressure processing to improve the color of dark cutting beef. Additionally, they are looking at alternative curing of beef products and a genetic defect related to glycogen in cattle. Derico compared the freezing of steaks to roasts, shipping optimization of beef, flavor studies, and microbiome of fresh meat. Chaoyu is a new member and rebuilding the program at the University of Connecticut. Their team is working on proteomics/metabolomics. Mahesh Nair discussed the national beef quality audit, impact of long term deep chilling (-2C), and evaluating the interaction between bacterial growth and color. Duane Wulf discussed the F94 myostatin mutation in dairy x beef steers, fatty acid composition of grain and grass finished beef, and a new product that could reduce stress in beef cattle leading to improved product quality.

Accomplishments

<p><strong>Arkansas - Derico Setyabrata</strong></p><br /> <p>The meat science faculty at University of Arkansas has been conducting several research projects in the past year focusing on freezing processes, color stability, product shipping optimization and waste utilization.</p><br /> <p><strong>California - Tim Hackmann, Payam Vahmani, Xiang Yang</strong></p><br /> <p>Beef is high in <em>t</em>10 fatty acids, which may reduce beef quality and healthfulness to consumers.&nbsp; It is known that <em>t</em>10 fatty acids originate from bacteria in the rumen, but these bacteria have been elusive.&nbsp; Here we identified a bacterium (Cutibacterium acnes AP1) that forms a <em>t</em>10 fatty acid (<em>t</em>10,<em>c</em>12-18:2) during biohydrogenation of linoleic acid.&nbsp; This bacterium and others forming t10 fatty acids could be important targets for improving the quality and healthfulness of beef.&nbsp;</p><br /> <p>Dr. Yang&rsquo;s lab continues to work on the assessment of antimicrobial resistance in beef production. One of the projects was to evaluate the effects of a supplemental blend of essential oils and 25-hydroxyvitamin D3 on the fecal resistome of steers. The ongoing project is to evaluate how extended colostrum feeding affect cattle health, performance and magnitude of antimicrobial resistance.</p><br /> <p><strong>Colorado &ndash; Mahesh Nair and Keith Belk </strong></p><br /> <p>The meat science faculty at Colorado State University (CSU) has been actively engaged in several research projects during the past year focusing on palatability, processing, marketing of beef, prevention of food-borne illness, and consumer preferences for beef. The National Beef Quality Audit research was completed and published in a peer-reviewed journal. In addition, the effect of low temperature on beef palatability and shelf-life was also investigated. Co-PI Mahesh Nair was awarded the 2024 Research and Scholarship Award by the College of Agricultural Sciences at Colorado State University.</p><br /> <p><strong>Connecticut &ndash; Chaoyu Zhai</strong></p><br /> <p>The meat science faculty at the University of Connecticut (UConn) developed a new peptidomic workflow for animal tissue diagnosis with low cost, high sensitivity, and fast matching speed, as well as the first analytical method to investigate non-targeted proteome degradation, which will be submitted for patent in the following year. By using these two methods, UConn meat scientist has been actively engaged in several research projects during the past year focusing on the effects of preharvest and postharvest factors on bovine postmortem muscle proteolysis and its relation to meat quality development. Dr. Zhai&rsquo;s first federal competitive grant application as primary investigator to NIFA was ranked as outstanding by the <em>Animal Nutrition, Growth, and Lactation</em> program and recommended for four-year funding ($650K) starting in August 2024.</p><br /> <p><strong>Florida - Tracy Scheffler</strong></p><br /> <p>Tracy Scheffler&rsquo;s lab is involved in research projects focusing on quality and yield of Brahman carcasses, and proteolysis and tenderness of Brahman longissimus. Ongoing work includes investigation of mitochondrial functional properties in relation to meat quality attributes.</p><br /> <p><strong>Idaho &ndash; Phil Bass and Michael Colle</strong></p><br /> <p>Beef meat science faculty efforts at the University of Idaho have been conducting research through the past year with focus on beef carcass quality and utilization of natural antioxidants to extend shelf life of beef patties. Focus has been on heavy weight carcasses and the effect of those carcasses on the merchandising of beef round cuts. Research has been conducted on both fresh and precooked beef patties utilizing a novel mustard extract alone and in combination with potato extract or rosemary extract. Aging strategies including freezing with dry ice and suspended fresh aging were evaluated. Lastly, various gluten free breddings were evaluated for use in finger steaks.</p><br /> <p><strong>Indiana - Brad Kim</strong></p><br /> <p>Dr. Brad Kim at Purdue University has been working on determining the impacts of post-harvest processing factors (developing &ldquo;Smart Aging&rdquo;, in particular) on meat quality attributes. In this reporting period, Dr.Kim&rsquo;s group worked on several beef projects &ndash; 1) NCBA funded fresh beef tumbling and aged/frozen beef for better quality and 2) continue working on USDA-AFRI grant project - the impacts of extended postmortem aging on color and redox stability of different beef muscles&nbsp;</p><br /> <p><strong>Kansas - Michael Chao</strong></p><br /> <p>Michael Chao&rsquo;s lab has investigated the use of electrostatic field (EF) to assist with the freezing process of beef striploins. The 4 EF treatments were 0, 2, 4, or 8 kV, and we measured how the EF application can affect beef color stability during the retail display of previously frozen beef striploins<em>.</em> In addition, we quantified alpha-gal content in different red meat products to provide a better understanding of how this allergen can trigger red meat allergy.</p><br /> <p><strong>Kentucky - Surendranath Suman</strong></p><br /> <p>Dr. Suman&rsquo;s lab examined innovative strategies to improve color stability of fresh beef with the ultimate goal to enhance retail color shelf-life and minimize discoloration-induced sales loss in the beef industry.</p><br /> <p><strong>Oklahoma - Gretchen Mafi</strong></p><br /> <p>Researchers at Oklahoma State have completed several projects on factors impacting dark cutting beef, freeze/thaw cycles on palatability, purge loss and yield, and research to determine surface area effects on oxygen scavengers in modified atmosphere packages.</p><br /> <p><strong>Texas - Wesley N. Osburn, Jeffrey W. Savell, Kerri B. Gehring</strong></p><br /> <p>A study was conducted to determine the impact of L-arginine (Arg) concentration on the ability of the endothelial nitric oxide synthase (eNOS) system to cure beef jerky and its effect on product attributes using two validated thermal processes. Arg treated samples showed no significant differences among concentration for any analysis with the exception of residual nitrite values at 1000 and 5000 ppm. It was observed that high temperature thermal processing treated samples tended to have slightly higher cured meat color values, a* values and residual nitrate and nitrite values low temperature thermal processing. As length of storage increased, nitrosohemochrome and a* values decreased as storage day. Results suggest that 1000 ppm Arg treated beef jerky thermally processed at higher temperatures were more similar to values observed for sodium nitrite treated control samples compared to the low temperature thermal processing.</p><br /> <p>A study was conducted to evaluate the impact of various combinations of refrigerated and frozen storage on quality and palatability attributes in ribeye roll and top sirloin butt subprimals and steaks. USDA Choice boneless ribeye rolls (<em>n</em> = 40) and top sirloin butts (<em>n</em> = 40) were aged under refrigeration for 21 d before being assigned to 1 of 4 treatments. Treatments included (1) Frozen subprimals/Frozen steaks, in which subprimals were frozen for 30 d, thawed for 7 d, and portioned into steaks that were frozen for 30 d, then thawed for 2 d before evaluation; (2) Frozen subprimals/Refrigerated steaks, in which subprimals were frozen for 30 d, thawed for 7 d, and portioned into steaks for evaluation; (3) Refrigerated subprimals/Frozen steaks, in which subprimals were portioned into steaks that were frozen for 30 d, then thawed for 2 d before evaluation; and (4) Refrigerated subprimals/Refrigerated steaks, in which subprimals were portioned into steaks for evaluation within 7 d of portioning. Beef steaks from the ribeye rolls and top sirloin butts were evaluated to determine the impact of storage treatments on purge, color, cooking yield, tenderness, and consumer acceptability. For both subprimals, purge varied (<em>P</em> &lt; 0.0001) among steak treatments, with Refrigerated/Refrigerated being the lowest for both subprimals. For both steak types, cook yield was highest (<em>P</em> &lt; 0.05) for Refrigerated/ Refrigerated treatment. Refrigerated/Refrigerated ribeye steaks had among the lowest Warner-Bratzler shear force values, and similar (<em>P</em> &gt; 0.05) consumer ratings were observed for ribeye steaks. Frozen/Frozen top sirloin steaks had the lowest (<em>P</em> &lt; 0.05) consumer ratings for overall liking, flavor liking, and juiciness liking. Storage conditions played a greater role in quality and consumer acceptability for top sirloin steaks than ribeye steaks. Overall, freezing both subprimals and steaks posed the greatest challenge in quality and palatability.</p><br /> <p>&nbsp;</p><br /> <p>For the National Beef Tenderness Survey &ndash; 2022, beef retail steaks from establishments across 11 US cities and beef foodservice steaks from establishments in 6 US cities were evaluated by consumer sensory evaluations and Warner-Bratzler shear (WBS) force analyses. The retail tenderloin had the lowest (<em>P</em> &lt; 0.05) WBS force value compared to other retail cuts. The retail steak with the greatest (<em>P</em> &lt; 0.05) WBS force value was the top sirloin. Foodservice ribeye and top loin steaks had greater (P&lt;0.05) WBS force values compared to the tenderloin. All retail top blade, bone-in ribeye, Porterhouse, and tenderloin steaks were categorized as&ldquo;very tender&rdquo; (&lt;31.4 N). There were no (<em>P</em> &gt; 0.05) differences in WBS force values among USDA quality grade groups for foodservice steaks. Retail tenderloin steaks received the highest (<em>P</em> &lt; 0.05) consumer rating for overall like/dislike, tenderness like/dislike,tenderness level, flavor like/dislike, and juiciness like/dislike compared to all other retail cuts. There were no (P&gt;0.05)differences among the 4 foodservice cuts for consumer sensory ratings of overall like/dislike, tenderness like/dislike, tenderness level, flavor like/dislike, and juiciness like/dislike. There were no (<em>P</em> &gt; 0.05) USDA quality grade differences for ribeye, top loin, top sirloin, and tenderloin foodservice steaks for overall like/dislike, tenderness like/dislike, tenderness level, flavor like/dislike, and juiciness like/dislike. Regardless of source (foodservice or retail), USDA grade group, or beef cut, measures of tenderness in this survey reveal ratings and values that should meet most consumer expectations in the marketplace.</p><br /> <p>&nbsp;</p><br /> <p>The National Beef Quality Audit (NBQA)-2022 serves as a benchmark of the current market cow and bull sectors of the U.S. beef industry and allows comparison to previous audits as a method of monitoring industry progress. From September 2021 through May 2022, livestock trailers (<em>n</em> = 125), live animals (n = 5,430), and post-slaughter hide-on animals (n = 6,674) were surveyed at 20 commercial beef processing facilities across the U.S. Cattle were transported in a variety of trailer types for an average distance of 490.6 km and a mean transport time of 6.3 h. During transit, cattle averaged 2.3 m<sup>2</sup> of trailer space per animal indicating sufficient space was provided according to industry guidelines. Of all trailers surveyed, 55.3% transported cattle from an auction barn to a processing facility. When surveyed, 63.6% of all truck drivers reported to be Beef Quality Assurance certified. The majority (77.0%) of cattle were sound when evaluated for mobility. Mean body condition scores (9-point scale) for beef cows and bulls were 3.8 and 4.4, respectively, whereas mean body condition scores (5-point scale) for dairy cows and bulls were 2.3 and 2.6, respectively. Of cattle surveyed, 45.1% had no visible live animal defects, and 37.9% had only a single defect. Of defects present in cows, 64.6% were attributed to an udder problem. Full udders were observed in 47.5% of all cows. Nearly all cattle were free of visible abscesses and knots (97.9% and 98.2%, respectively). No horns were observed in 89.4% of all cattle surveyed. Beef cattle were predominantly black-hided (68.9% and 67.4% of cows and bulls, respectively). Holstein was the predominant dairy animal observed and accounted for 85.7% of the cows and 98.0% of the bulls. Only 3.1% of all animals had no form of identification. Findings from the NBQA-2022 show improvements within the industry and identified areas that required continued education and research to improve market cow and bull welfare and beef quality.</p>

Impact Statements

  1. Arkansas - Derico Setyabrata The research in Arkansas is expected to further understand factors impacting beef quality and mechanism related to discoloration and shelf-life. California - Tim Hackmann, Payam Vahmani, Xiang Yang Our long-term goal is to manipulate the composition of beef fat and make beef more marketable to consumers. This goal directly enhances competitiveness and value of US beef. The research projects conducted in Dr. Yang’s lab provide valuable insights into antimicrobial resistance in cattle production, serving as a valuable resource for producers, government regulators, and a source of education for consumers. Colorado - Mahesh Nair and Keith Belk The research conducted at Colorado State University will improve our understanding of postmortem metabolism and beef quality development, especially quality parameters such as color, tenderness, and flavor. In addition, it will help to improve the shelf life and safety of beef products in the U.S. Connecticut – Chaoyu Zhai The research conducted at the University of Connecticut will improve our understanding of the relation between postmortem proteolysis and meat quality development, which will minimize beef quality defects to ensure the competitiveness and sustainability of US beef production. Florida - Tracy Scheffler Research conducted at the University of Florida aims to enhance the understanding of early postmortem metabolism and its influence on development of beef quality attributes. A major aim is to identify factors that contribute to variation in proteolysis, particularly in Bos indicus beef, in order to improve product quality and consistency. Idaho – Phil Bass and Michael Colle The previous and ongoing research at Idaho continues to work to improve product quality and consistency. Our main goal is always to find ways to increase beef consumption and acceptance which thereby adds value to all segments of the beef industry. Indiana - Brad Kim Dr. Kim’s research program at Purdue University centers around three major research objectives: 1) identify fundamental biochemical mechanisms governing meat quality attributes, such as color, tenderness, flavor, water-holding capacity and juiciness, 2) develop innovative technologies from the live animal pre-harvest to the post-harvest chain of events to improve meat quality, and 3) identify and develop novel meat or non-meat ingredients to create values from underutilized low-value sources. Kansas-Michael Chao Dr. Chao’s research at Kansas State University can be roughly categorized into 3 major areas: 1. Understanding the relationship between collagen characteristics and beef texture. 2. Using lipidomics and proteomics to understand the alterations of various beef quality attributes. 3. Improving the values of lower quality beef cuts. Kansas - Logan Britton The research conducted will help understand U.S. and international consumer behavior toward purchasing and consuming beef products. The results from this project could help stakeholders determine effective strategies, such as pricing, attribute callout, etc. to market products among different consumer segments. Kentucky - Surendranath Suman The results from this project could be exploited as a post-harvest strategy to improve retail color stability and tenderness of beef biceps femoris and increase the value of this underutilized muscle. Oklahoma - Gretchen Mafi Research in our lab continues to find methods to improve quality and improve retail color stability to reduce waste and improve efficiency and ultimately value. Texas - Wesley N. Osburn, Jeffrey W. Savell, Kerri B. Gehring It is expected that investigating cofactors required to activate the eNOS enzyme will improve our knowledge and understanding of the chemical, physical, and biological properties of meat products cured via an amino acid alternative curing system this alternative curing method by eliminating the need for direct addition of sodium nitrite. We expect to achieve better understanding of the interconnected biochemical mechanisms contributing to the functionality of the NOS system in post rigor skeletal muscle which will be translatable into actionable compositions and processes with practical application in curing beef products. From Savell and Gehring, several research projects were completed, and multiple grants have been awarded during the past year. In addition several graduate and undergraduate students were trained during this time period.
