Brief Summary of Minutes of Annual Meeting

1. Introduction:

Introductions

Previous meeting minutes had not been distributed. Need to do so.

Jeff Brecht (JKB) explains that we are in a new 5-year project as of October 1, 2022. The new project followed the previous, with the same four objectives. What is new: expanded from fresh-cut to whole products that can be processed to create fresh-cut vegetables and fruits.

2. Welcome from Administrative Advisor:

Scott Senseman (SS), Project Administrator, invites everyone to go to the NIMS project web site. Need to get the meeting information early in order to get early authorization.

JKB informed that in January 2022, IFPA merged with PMA. IFPA used to meet in the Spring, PMA in the Fall. Funding for travelling has been an issue in the past. Need to make sure not to spend everything before the next meeting since the next IFPA meeting will be in the fall as well, and funds will be distributed earlier in the year. It was noted that all members need to create in the new NIFA research project system a version of the S294 project that is specific for their institution – Hatch funds can only go to your institution and to you, the researchers, if there is such a project. Your project can use whatever parts of the S294 MultiState Project Statement (at www.nimss.org) are appropriate for the research you plan to do over the next 5 years.

SS says that every institution handles the distribution of Hatch funds differently, some might use it as salaries. Participants should let their administration know if they have problems getting the money they need to attend the S294 Annual Meeting and to conduct research.

Eva Almenar (EA) suggests that the information about funding should be posted on the NIMSS web site, to attract new members. She says our experimental stations receive multi-state funds and in the past, these funds have been used to cover salaries partially and travel expenses to attend the annual meeting, and/or to support research projects (e.g., purchase of a texturometer). Each experimental station handles the funds differently. New members are encouraged to contact their experimental stations to learn more about this available funding.   

3. Elections

Currently, JKB is the Chair, Floyd Woods was the vice chair, Angela Shaw was the secretary. They are 2-year commitments. Floyd took an early medical retirement at Auburn, so he is no longer participating in S294. Angela moved from U. Illinois to Texas Tech and is no longer working with fresh-cuts, so she is also no longer participating in S294.

Anne Plotto (AP) nominated Jorge Fonseca as Chair. He accepted.

JKB nominated Tie Liu as Vice Chair. He accepted.

EA nominated AP as secretary. She accepted to be the secretary for one year.

JKB about recruiting participants: the S294 mailing list has 34 names, only 12 are registered on the NIMSS web site.

4. Improving S-294 engagement with IFPA

Gretchen Wall:

She is the first official hired by IFPA and is the Director Food Safety and Quality. She previously worked 11 years at Cornell University in extension service. She is now the new director of Food Safety and Quality. The UFPA’s Food Safety & Technology Council (FSTC) continues with IFPA, with about 40 industry reps.

Produce Quality Sub-Committee: There are 20 members right now, the group description and goals and priorities are still under discussion. Jeff Brecht, Angelos Deltsidis (UGA), and Trevor Suslow (retired UC, Davis, former S294 member) are members of that sub-committee.

IFPA provides micro-volunteer opportunities, to get in touch with members. Gretchen Wall is the contact person if anyone from S-294 is interested. The IFPA Fresh Produce Research Center will connect academia with industry. For more information, please see the IFPA web site. https://www.freshproduce.com/who-we-are/fresh-produce-research-center/

JKB noted that there is another Food Safety MultiState Project, which explains why some of our food safety area members left S-294 to join that other group. Other former S294 members have been lost to retirements (Marita Cantwell, Trevor Suslow, Michael Saltveit, Diane Barrett), and Linda Harris from UC Davis moved from research to administration). JKB mentions that we should have a S-294 representative on the Food Safety & Technology Council of IFPA, which has 40 members.

5. Station reports:

ARS-Florida (Bai & Plotto)

Winter melon fruit and jicama roots are being explored as low-sugar/low calory juice

LED lights for microgreens and tomatoes, in greenhouse

Citrus, strawberry quality from breeding programs

Fresh-cut mangoes (joint project with UF – see below under the Florida report).

ARS-Beltsville (Fonseca)

This Unit has 7 scientists. Tian Bao Yang has a patent pending on two compounds to accelerate ripening of non-climacteric fruit on the plant (cherry, strawberry…). He is also working to improve nutrition content in microgreens.

Yaguang (Sunny) Luo has a patent on a vertical system to wash and sanitize leafy greens, the “tumble zone”. She is still working on the design of the nozzle. She has a collaboration with ARS in California to select cultivars for fresh-cut lettuce.

Bin Zhao has a collaboration with Texas A&M for non-particle coating. The question is whether it can work on the surface of fresh cut tissue.

The Beltsville Unit investigates e-commerce for consumer preferences. Relationship between online and real-time products using eye-tracking.

Mycotoxins in fruit: blue mold in blueberry and apples.

University of Florida:

Tie Liu, Jeff Brecht and Eleni Pliakoni (KSU): Project to identify marker genes that identify stages of senescence in broccoli, with the goal to design a fast assay. These kinds of genes are called SAGs (Senescence-Associated Genes)

Sargent and colleagues compared forced air/hydrocooling/slushed ice for cooling broccoli. Found that they are all equivalent as long as RH is maintained. Also worked with lettuce breeder and a PhD student (Catherine Belisle) to reduce pink rib.

Brecht and Plotto (ARS-Ft. Pierce) headed a project to extend the shelf life of riper (than currently used commercially) fresh cut mango. A handbook, Fresh-cut Mango Best Management Practices, is being prepared for release in 2023.

Michigan State University, School of Packaging (Almenar)

Investigated orange peel waste to be used as a “filler” in rigid and film packaging

Blown film extrusion development

Mississippi State Univ. (Rama Nannapaneni)

Rama had a power point presentation.

Iowa State U. (Byron Brehm-Stecher)

Nothing to report for this past year. Byron mentioned a few names of researchers in the food safety and microbiology area that could join S-294 – see list at bottom of minutes.

6. Research Proposals, Conference Proposals to USDA, Wrap-Up Session:

EA is reiterating the need to interact with industry members. Suggests to have the S-294 meetings in the am, and meet & greet with industry in the pm. There was a brief “meet & greet” with the IFPA Quality Group on October 28^th at 1:00 pm.

The goal of this group (S294) is to work on projects together, as there are funding opportunities.

Idea to create a Center for Produce Safety, virtual.

Also, importance to have an advisory board who can react to researchers’ ideas.

IFPA receives a lot of requests for information from industry. They are “match makers” between academia and industry. Jennifer is the contact person.

Jorge suggests that we resend the bios of each S-294 member to IFPA.

The FSTC addresses issues that are more regulatory than research.

Need to put together a conference proposal to USDA. The money is there, need to use it.

Discussion about symposium, communication with industry. The new IFPA is trying to be more engaging.

8. Chang Chen (starting at Cornell, June 2023)

Objective 1. Evaluate methods of sampling and measuring flavor and nutrition of fresh-cut products to facilitate comparison to traditional shelf life factors:

Determine Saffron purity using deep learning optimization: This novel approach is an efficient alternative to separating pure from non-pure products that can subsequently benefit the saffron industry from producers to consumers and could serve as a basis for use with other spices. (USDA MD)

Objective 2. Develop new strategies to improve and better maintain inherent fresh-cut product quality and nutrition:

Orange peel waste from juicing as raw materials for plastic composites intended for use in food packaging. Eight different LLDPE/OP sheets from combinations of different OP characteristics are examined. Results show that OP particle sizes of 75-177 µm without zest at 0.4-g loading improve thermal stability, color, dispersion, tensile strength, modulus of elasticity, and elongation at break as well as reduce air bubble formation and OP agglomerate sizes in LLDPE/OP composites. Results show a promise in utilization of OP fillers to produce a composite comparable to neat LLDPE and composites with UV-blocking properties. (MI)

Use of orange juice processing waste to produce films using blown film extrusion for food packaging. Blown film extrusion can produce continuous bio composite films made of OP waste. Blown film extrusion conditions to replace 11.5% of plastic with OP were determined.  Bio composite WV barrier and thermal properties are the same as those of neat films. The blown bio composite LLDPE/OPP films can be used for food packaging applications. (MI)

Antimicrobial activity of orange juice processing waste in powder form and its suitability to produce antimicrobial packaging. Antimicrobial activity of orange juicing waste in powder form (OPP) was demonstrated. Antimicrobial films using OPP instead of extracted essential oil were developed.  Reduction of waste by replacing about half of the plastic in the film with OPP.  The film showed less antimicrobial activity than OPP due to limonene & citral loss. Film mechanical & barrier properties were similar to those of common plastics. (MI)

Overcoming limitations for processing riper mango fruit for fresh-cut mango. Developed recommendations for minimum firmness for processing different mango cultivars (Tommy Atkins, Keitt, Kent), with and without additives and MAP. (UF/USDA FL)

Retrofitting refrigerated retail display cases to improve temperature management and maintain quality of fresh-cut leafy greens. We showed that the lower temperatures in enclosed refrigerated retail display cases maintain higher quality of leafy greens. An approximately 3 degree C temperature difference before versus after display case retrofitting resulted in improved quality maintenance of baby spinach, spring mix and Romaine lettuce; we also demonstrated lower microbiological populations on chopped Romaine lettuce. (UF/USDA MD)

East Coast Broccoli Project - cultivar and precooling method evaluations. Quality evaluation of commercial broccoli cultivars and breeding selections for potential winter production in north Florida (part of East Coast Broccoli Project) was done. There were inherent differences between cultivars, but cooling with slush ice or hydrocooling did not result in differences in quality changes during storage; plastic film overwrap was effective in reducing water loss during storage. Samples from broccoli storage regimes were analyzed for nutritional content at Univ. of Tennessee in Dr. Carl Sams' laboratory. (UF FL)

Accelerated shelf-life testing at higher than optimum temperatures was used to predict quality loss in Romaine-type lettuce. (UF FL)

Developing effective pre- and postharvest methods to control Diplodia stem-end sot (Lasiodiplodia theobromae) and reduce mandatory segregation of fresh Florida grapefruit exports arriving in Japan. Several fungicidal materials were tested pre-harvest on mature grapefruit trees to prevent post-harvest decay due to Diplodia stem-end rot (SER) caused by Lasiodiplodia spp. Two fungicides significantly reduced fruit decay, while an essential oil (thyme oil) had no effect. Post-harvest applications of gaseous chlorine dioxide (ClO₂) effectively reduced Diplodia SER on inoculated fruit; however, phytotoxicity was observed as peel injury when ClO₂ doses exceeded 1 g per kilo of fruit. In the end, treatments of gaseous fast release CO₂ in an enclosed chamber at a rate of 1 g per kilo of fruit and duration of 8 hours effectively controlled Diplodia SER in grapefruit. (UF/USDA FL)

Develop low calorie juice using winter melon and jicama roots. Winter melon and jicama roots are productive and have the advantage of storing up to 4 months without deterioration of the fruit/root. Processing methods to optimize flavor and nutritional content were established. (USDA FL)

Improving microgreen and tomato yield and quality by regulating LED light combinations. Blue and red lights are extensively used in controlled environment agriculture as light sources or supplementary lights. We have been focusing on additional lights to improve vegetable quality and enhance the tolerance of tomatoes to postharvest chilling injury. Our results indicate that green light can increase the yield of microgreens and enhance the volatile intensity in addition to blue and red light treatments. We will confirm if adding far-red light in the blue/red lighting growth chamber can enhance tolerance of tomatoes to postharvest chilling injury. (USDA FL)

Cold plasma treatment promotes seed germination and enhances isoflavone content in soybean sprouts. Cold plasma treatment increased the germination rate, fresh weight, and stem and root length of soybean sprouts. The cold plasma treatment also enhanced the activities of superoxide dismutase, catalase and peroxidase, and the total antioxidant capacity in sprouts and increased isoflavone content. (USDA MD)

Reducing postharvest loss and improving fresh produce marketability and nutritive values through technological innovations and process optimization. Identified browning resistant lettuce cultivars to minimize post-harvest food loss and waste. Utilized well-constructed digital images for browning and sensory research during storage. (USDA MD)

Assessment of a novel in-flight washing device: microbial reduction and food quality of chopped iceberg lettuce during storage. Use of the IFW can improve postharvest food safety and quality of fresh-cut lettuce, compared to conventional flume washing. (USDA MD)

Objective 3. Improve understanding of physiological mechanisms that affect fresh-cut product quality:

Transcriptome analysis of tissue browning of fresh cut lettuce. Lettuce tissue browning is mainly controlled by phenolics biosynthesis and growth hormone signaling. (USDA MD)

Identification of browning-resistance lettuce cultivars for fresh-cut processing. Identified and characterized, for the first time, the association between stem and leaf browning of lettuce, enabling the development of a novel approach to predict browning in leaf ribs (difficult to measure) based on stems (easier to measure). The new method largely simplifies the lettuce cultivar screening procedure. (USDA MD)

Objective 4. Determine critical factors in controlled inoculation studies with human pathogens and surrogates that influence the outcome of quantitative microbial risk assessments:

Determine the effect of temperature abuse timing on shelf life of RTE baby spinach through microbial growth models and its correlation with sensory quality. Assessed effect of temperature abuse timing on microbial growth on RTE baby spinach. Indigenous microbial populations were correlated with sensory attributes of baby spinach. Mathematical models were developed and validated to predict microbial growth. (USDA MD)

Cold plasma activated hydrogen peroxide aerosols inactivate Salmonella Typhimurium & Listeria innocula on smooth surfaces and stem scars of tomatoes: modeling effects of hydrogen peroxide concentration, treatment time & dwell time. Listeria was more sensitive to cold plasma-activated H2O2 aerosol than Salmonella on tomatoes; At ≥5.7% H2O2, both bacteria on the surface of tomatoes were reduced by 5 logs. (USDA PA)

Reduction of Salmonella enterica Typhimurium populations and quality of grape tomatoes treated with dry and humidified gaseous ozone. Compared with dry ozone, humidified ozone had two benefits: (1) increased efficacy against Salmonella, and (2) reduced damage to fruit quality. (USDA PA)

Biocide tolerant Listeria monocytogenes and Salmonella Typhimurium surviving in first and second generation QAC. We have isolated distinct morphotypes of L. monocytogenes surviving after frequent exposure to first generation QAC, benzalkonium chloride (BAC), that exhibited a low-level tolerance to BAC versus parent strain. (MS)

Objective 5. Development and validation of novel diagnostic methods to determine presence of human pathogens and chemical hazards associated with fresh and fresh-cut products:

Biocide tolerant Listeria monocytogenes and Salmonella Typhimurium surviving in first and second generation QAC.  We are optimizing the steps for the isolation and confirmation of persistent cells and subpopulations of L. monocytogenes that tolerate commonly used disinfectants which may survive longer in some food processing environments. (MS)
