NC-213 Annual Meeting 2025

Janie Moore proposed site options for 2025

Unanimous vote for Wheat Quality Council in Olathe, Kansas for 2025

Janie proposed that we identify a location for 2026 as well and consider having a set rotation for our annual meetings.

Deanna offered to have 2026 at K-State/USDA and Griffiths also offered to have 2026 at U of Arkansas.

Vote of the station representatives selected U of Arkansas for the 2026 meeting.

While there was some consensus about where we will host the meetings from year to year, we left it open for change.

Chuck Hill pointed out that we will need to keep GEAPS and Wheat Quality Council back to back, then go to a Land Grant

Suggested Meeting Schedule:

2025 – Wheat Quality Council

2026 – Univ of Arkansas

2027 – GEAPS

2028 – Wheat Quality Council

2029 – K-State/USDA

Appointment of Secretary

George Annor was the nominee for the Secretary and approved by the voting members.

Kaliramesh Siliveru did express interest in the position for the coming year.

Awards were presented before the business meeting by Devin Rose

Salah Issa – Early in Career

Griffiths Atungulu – Cereals and Oilseeds Award of Excellence

Jiaying Wu from Illinois - Student Poster Competition

While the virtual poster session went well, there are some improvements that could be made if we decide to try it again.

Have students record themselves presenting their work and have those videos available before the meeting.

Go back to the “people’s choice” and let everyone have an opportunity to vote on the posters (at Purdue we used those tokens and the students with the most tokens won, this year we gave industry reps a rubric to score and then tallied points)

Meeting adjourned.

Accomplishments

NC-213 2023 Accomplishments Objective 1: To measure, model, and assess factors which influence quality and safety attributes in the post-harvest usage, drying, handling and distribution of cereal grains and oilseeds.   NC213 researchers across multiple universities and USDA facilities have been conducting research studies across the post-harvest supply chain. Studies include alternative uses for naturally occurring DON-contaminated grain, mycotoxin prevalence in Iowa corn, developing support tools and guides for post-harvest technology uses, improvements on airflow in grain ground piles, and mitigation techniques for pathogens in wheat. NC213 researchers have published >30 peer review publications, developed 3 online dashboards, and presented at national and international conferences.   Selected highlights from individual research stations.   Researchers at Iowa State University have studied and developed decision support tools to guide assessments and adoption of post-harvest technologies to ensure food security. The Rockefeller Foundation YieldWise Initiative (YWI) was used as a case study to develop the first-generation support tool to compare post-harvest losses associated with different technologies, along with surveys from 600 participants from Kenya, Tanzania, and Nigeria.   Research is underway at the University of Nebraska – Lincoln to investigate mitigation strategies to reduce the natural microbial load of hard red winter wheat. This research addresses the food safety concerns of microbial contamination in wheat flour and is a potential novel treatment to reduce microbial loads.   Researchers at Texas A&M studied naturally contaminated maize samples with aflatoxin, to obtain spectral data that was processed and analyzed using a machine learning method. The findings and implications from the study indicate the potential use of a compact and automated Raman system, coupled with machine learning methods would be a more rapid and less expensive analytical tool for hazardous substances at on-site field processing locations.   Researchers at the USDA – ARS evaluated a handheld NIR instrument compared to a benchtop NIR for predicting protein content in sorghum grain. The handheld NIR would offer growers and producers a more rapid prediction of sorghum grain composition   Objective 2: To improve management and operational systems to increase efficiency, retain quality, enhance values and reserve food safety in the farm-to-user supply chain.   NC213 researchers from across the station locations have been pursuing research and extension efforts on systems approaches for the post-harvest supply chain. NC213 researchers have produced a combined, 41 peer review publications under this objective. The University of Arkansas held their annual industry alliance meeting to share research findings with stakeholders, academics, and sponsors of the rice processing program. Advances in mycotoxin and aflatoxin research from Iowa State University, the USDA, and Mississippi State University have been made through the NC213 collaborations. Collaborative research projects were conducted on control strategies for stored product insects on multiple stored grain commodities and aerosol treatments for processing facilities, which resulted in increased awareness of treatment options for stored product pests.   Selected highlights from individual research stations.   Iowa State University has been researching and testing new wireless monitoring systems aimed to replace temperature cables with the headspace of a grin bin, and plenum sensors that monitor temperature, relative humidity, and CO2 concentration during grain storage. The goal of the new system is to monitor grain conditions, make aeration decisions, and provide warnings of grain spoilage in time to act to reduce losses.   Researchers at Kansas State University have developed a big data framework to track the distribution of pathogens in the wheat supply chain. They consider a detailed wheat supply chain where temperature and humidity are the two main parameters responsible for bacterial contamination at any point in the network. They intend to explore interactions between several parameters other than temperature and humidity and validate the model with realistic data. Purdue University is currently working on creating a searchable online database for grain, co-products, and biomass physical properties The user-friendly web application tool is being developed using the open-source, server-based programming language, for easy retrieval of data.   Objective 3: To work with multi-institutional colleagues to improve the cereal grain and oilseed supply chain by creating measurable impacts that preserve quality, increase value and maintain food safety/security.   NC213 researchers from station locations participated in the Annual Meeting, where current research activities were presented and discussion among the research stations occurred. These interactions lead to new ideas, practices, and research projects among NC213 researchers to address specific engineering, scientific, and economic issues.   Highlights from individual research stations.   The Iowa State University (ISU) Kent Feed Mill and Grain Science Complex was officially dedicated in September 2023. This new facility provides a unique capability to allow for NC213 research collaborations between universities, USDA facilities, stakeholders, and industry partners to study the post-harvest supply chain and develop strategies to improve post-harvest storage, processing, and management systems. In addition, on-site training and coursework were conducted in this new facility to help grow the post-harvest community and to train the next generation of scientists.

Impact Statements

Research conducted by NC-213 Scientists on steam treatments of wheat addresses the food safety concern of microbial contamination in wheat flour and introduces a novel method involving lactic acid and steam treatment to significantly reduce microbial loads without compromising the functional properties of flour.
Research conducted by members of NC-213 show that Solvent Retention Capacity (S.R.C.) is useful for the evaluation of specific flour polymers of HRS wheat cultivars for their end-use potential. Traditional SRC solvents are useful for millers due to the rapid prediction of flour quality parameters, while the supplemental SRC solvents can be used to predict the hard wheat quality since the successful correlations with protein quality-related parameters. The development of the supplemental solvents has gained traction among U.S. wheat customers across the global market, especially by Southeast Asian customers.
A compact and automated Raman system developed by NC-213 collaborative efforts is a highly applicable alternative tool for qualitative and quantitative analysis of aflatoxin in a variety of feed and food matrices since it is rapid, non-destructive, and cost-effective as a screening tool. The proposed Raman system can be capable of rapidly measuring contaminated samples with higher sensitivity and specificity to conduct automated sample analysis. As a result, it can serve as a powerful method to help control contaminated feed and food products for improvement of the safety in the grain industry.
Study conducted by NC-213 researchers reveals the real-time data sharing capabilities of a point-of-need (PON) reader with a proof-of-concept centralized and cloud-based AF databank. This databank can facilitate timely monitoring across different facets of food systems, ensuring accessible data for early warnings, data-driven decisions, rapid interventions, and enhanced coordination among diverse stakeholders within the food system. With wireless data transfer, it can facilitate real-time data collection, stored in a cloud-based AF database, revolutionizing efficient and cost-effective food safety monitoring.
Studies have proven that Aflatoxin is regarded as one of the most important food safety problems in the world. Corn contaminated with toxigenic strains of A. flavus can result in great losses to the agricultural industry and pose threats to public health. The research effort aims at providing a rapid, non-destructive method for screening corn at elevators or grain collection points, identifying and diverting contaminated grain into alternative uses, thereby protecting the food supply and increasing producer profitability. Results from this current NC-213 study enhanced the potential of using multispectral imaging for the detection of fungal infected and aflatoxin contaminated corn.
Research has proven that all food processing facilities and warehouses vary in size, structural components, design, etc. which challenges pest management professionals. Using the information in this NC-213 led study, the general public and researchers can better understand the relationship between a structural design, aerosol application type and technique, to better understand particle deposition and predicted efficacy. This information can be used and will lead to better, more uniform, and effective aerosol insecticide treatments.

Accomplishments

Accomplishments & Impact Statements NC-213 2024 Accomplishments Objective 1: To measure, model, and assess factors that influence the quality, safety, and nutrition of cereal grains and oilseeds during post-harvest drying, storage, processing, and distribution. NC-213 researchers from various universities and USDA facilities have been conducting collaborative studies. Their research includes the development of robust calibration models for near-infrared (NIR) spectroscopy for rapid and non-destructive chemical analysis; evaluation of the environmental and economic impacts of low-temperature, closed-cycle grain drying; investigation of the stored grain ecosystem within grain bins; analysis of the relationship between the solvent retention capacity (SRC) test and quality assessments of hard red spring (HRS) wheat; and examination of the effects of processing on wheat quality and nutrient content. Additional efforts have focused on integrating approaches for enhancing the profitability of the shea nut value chain, developing a novel triaxial pressure sensor for in-situ measurements in grain bins, identifying factors influencing sorghum grain composition, and designing a portable multimodal optical sensing system. NC-213 researchers have published over 20 peer-reviewed articles and presented their findings at both national and international conferences.   Selected highlights from individual research stations: <ul> <li>Researchers at the University of Illinois established robust calibration models for rapid and non-destructive chemical composition analysis of corn and soybean. They conducted external validation using independent sample sets to assess model reliability and evaluated performance using statistical metrics such as R², RMSEP, and RPD. They also collected corn samples from various states and countries to develop global models. They identified the optimal spectral features and spectral ranges associated with variations in moisture, protein, starch, and oil content in corn. Besides, they designed and implemented a graphical user interface (GUI) for spectral data analysis. The GUI integrates advanced data processing and chemometric analysis tools for NIR spectroscopy, enhancing the accessibility of spectral analysis for researchers and industry professionals.</li> <li>Researchers at Iowa State University conducted a study to understand the environmental and economic impact of low-temperature, closed-cycle grain drying by using techno-economic analysis (TEA) and life cycle assessment (LCA). LCA results indicated that greenhouse gas (GHG) emissions increase along with the expansion of the drying system since the electricity comes from a local-coal-based electricity plant. In addition, the Iowa State University grain quality laboratory created corn and soybean proximate analysis calibrations for multiple models of near infrared transmission (NIRT) analyzers. Calibrations were validated by instrument model to reference chemistry on an annual basis. Reproducibility and repeatability were tracked. A review paper was published in 2024 detailing costs and benefits of applications of NIR HSI for safety and quality evaluation of animal feed ingredients.</li> <li>Researchers at University of Kentucky introduced a novel triaxial pressure sensor for in-situ measurements in grain bins. The sensors were housed in a 3-D printed shell, with three load cells and a digital camera. The results showed a clear radial variation in pressure. The data was within 5-25% of the Janssen equation, and the variation reproduced features from previously published literature. This study was limited by the small number of experiments conducted. The sensor design could be improved by exploring diaphragm-style sensors, which allow for increased sensitivity and reduced friction.</li> <li>Researchers at University of Nebraska determined the effect of processing on micronutrients, cadmium dialyzability, and cellular bioaccessibility of wheat. Boiling and germination failed to improve beneficial micronutrient bioaccessibility compared to raw flour. Fermentation increased the bioaccessibility of cadmium, magnesium, iron, and zinc. Dialyzability only presented a valid correlation with bioaccessibility for cadmium (r = 68; p < .001). Thus, food processing did not decrease cadmium bioaccessibility from wheat porridge. They also conducted research on wheat end-use quality. They evaluated the Glutopeak instrument for its suitability as a replacement for the Mixograph. The corresponding rheological parameters were significantly linearly correlated between Glutopeak and Mixograph: mixing time, torque and energy (r >0.75; p < .001). The wheat flour protein concentration showed more significant corrections with rheological properties of GlutoPeak than those of Mixograph. The wheat flour bread baking characteristics (i.e. loaf volume and texture) showed stronger corrections with rheological properties of GlutoPeak than those of Mixograph.</li> <li>Researchers at Purdue University conducted research to better understand the stored grain ecosystem in a grain bin across different seasons. The study results showed that monitoring of carbon dioxide (CO2) at the plenum followed similar trends with CO2 levels at the headspace. There were significant differences (p < 0.05) in the CO2 concentration levels at the plenum and headspace during fall, spring, and summer. In addition, researchers at Purdue University examined the relationship between the solvent retention capacity (SRC) test and quality assessments of HRS wheat grown at four locations in North Dakota in two years.  The study results showed that differences in locations contributed significantly to variation in quality parameters and traditional and supplemental SRC values within the same year. Traditional SRC values and gluten performance index (GPI) significantly (p ≤ 0.01) correlated with flour components and Farinograph water absorption. In addition, highly significant (p ≤ 0.001) correlations were found between the supplementary solvents and analyzed rheological and baking quality parameters especially with water absorption and loaf volume.</li> <li>Researchers at Texas A&M designed a portable multimodal optical sensing system for fast, automated, and intelligent inspection of biological and chemical hazards. The software components enabled the system to perform spectral and image preprocessing. Additionally, machine learning algorithms were integrated to enhance the system's capability to automatically analyze the data and make intelligent assessments and improve the accuracy and efficiency of food safety applications, which facilitates rapid detection and analysis of biological and chemical hazards in grain products. In this study, they achieved a classification accuracy exceeding 95%, effectively identifying varying levels of contamination within these samples.</li> <li>Researchers at the USDA-ARS investigated factors influencing the composition of sorghum grain via experiments on the timing and application of nitrogen fertilization as well as transcriptome and metabolomic studies. They also determined the effect of heating sorghum flour on the phenolic content and produced gold nanoparticles from sorghum and wheat bran. Research was also conducted to determine how ultrasound tempering of sorghum grain influenced milling quality.</li> </ul>

Impact Statements

• Grain Quality and Testing: NC-213 researchers developed non-destructive NIR spectroscopy tools for analyzing corn and soybean composition. These tools reduce the need for traditional lab methods and make testing more accessible for producers and researchers across regions.
• Grain Storage Management: Research identified how corn susceptibility to spoilage changes throughout the year, helping storage operators better manage insect pressures, moisture, and gas buildup. This has led to improved safety and efficiency in grain storage.
• Food Safety Innovations: A portable optical sensing system was developed for rapid detection of aflatoxins in food and feed. Its speed and accuracy offer a cost-effective solution to monitor contamination and protect public health.
• International Development: In Ghana, NC-213 researchers evaluated shea butter processing systems and identified that scalable mechanization can improve income potential for rural producers and help them access premium markets.
• Wheat Quality Assurance: Studies on wheat flour quality led to the identification of new testing methods using supplemental SRC values and Glutopeak instruments. These approaches ensure continued quality assessment in the absence of outdated technologies.
• Functional Food Development: Hemp seeds were found to have high antioxidant activity, encouraging their use in developing foods that may help reduce the risk of chronic diseases.
• Equipment Design Support: NC-213 researchers collaborated with engineers and manufacturers to develop a device for measuring pressure in grain bins, aiding the design of safer, more effective storage systems.
• Sorghum Utilization: Research linking sorghum grain chemistry to end-use quality supports breeders, growers, and food companies in improving sorghum products and expanding market opportunities.
• At the University of Arkansas, researchers partnered with grain producers, processors, and engineers to evaluate equilibrium moisture content (EMC)-based in-bin drying systems. Through field experiments, simulations, and sensor technology, the team answered critical questions regarding the quality degradation, mycotoxin development, and energy savings potential in rice drying and storage systems. Their work resulted in a validated simulation platform for natural air in-bin drying, practical for Arkansas-specific conditions. Charts were produced to guide fan control strategies and storage practices based on harvest conditions, enhancing engineering and management practices for high-quality grain storage.
• Iowa State University collaborated with USDA researchers in New Orleans to analyze state-specific patterns in fumonisin contamination in corn. This work revealed surprising differences in predictive factors between Iowa and Illinois, despite their agronomic similarities. One publication emerged from this partnership, improving the industry's ability to forecast mycotoxin presence across U.S. corn-growing regions and enabling more informed mitigation efforts.
• In response to producer demand for non-GMO feed ingredients, Iowa State researchers investigated the economic and logistical feasibility of minimizing adventitious presence (AP) of GM grain. Using Monte Carlo simulations, the team found that segregating non-GM corn and soybeans typically increased costs by 3–4 cents per bushel. These findings help quantify the real-world trade-offs and support decision-making in supply chains aiming to deliver verified non-GM products.
• Iowa State researchers also advanced thermal processing efficiency by collecting extensive steam and mash data at the ISU feed mill. Sensor retrofits allowed measurement of steam losses, temperature, and moisture through each stage of feed processing. The results showed steam utilization efficiencies averaging over 70%, with minimal energy losses. Recommendations included system enhancements, such as installing rotary airlocks to improve heat retention between stages. This work sets the foundation for automating thermal processing in feed manufacturing, improving sustainability and precision.
• In studies of grain flow and traceability, Iowa State researchers created and repeatedly tested a benchtop flow model to track grain movement during discharge from storage bins. Using both uniform particles and actual corn and soybeans, experiments demonstrated consistent last-in-first-out (LIFO) flow patterns, with corn showing more distinct flow peaks. These insights are critical for understanding contamination risk and quality segregation in bulk grain handling.
• At Kansas State University, a team explored chlorine dioxide as a novel fumigant for stored grain pest control. Due to its higher hazard profile compared to traditional fumigants, researchers developed an active treatment protocol integrated into the grain receiving process. Preliminary tests using 50-lb batches confirmed chlorine dioxide’s efficacy against common grain pests, offering a possible path forward for safer and scalable fumigant delivery.
• Additional Kansas State research evaluated alternative fumigants—methyl benzoate (MB) and acetophenone (AP)—against pests like the lesser grain borer, rice weevil, and red flour beetle. While both compounds exhibited significant toxicity to adult and immature insect stages, they were not fully effective against mixed life stage infestations, likely due to lower gas concentrations and larval tolerance. Still, their inhibition of acetylcholine esterase suggests potential for development as biologically active grain protectants.
• To meet the growing demand for residue-free grain protection, Kansas State researchers also tested amorphous silica powders as insecticides. One powder, applied at 0.20 g/kg, resulted in nearly 100% adult mortality and significantly reduced progeny production and grain damage. The second powder achieved complete mortality and outperformed the first, due to higher oil adsorption and low pH. These findings support expanded use of diatomaceous earth alternatives for effective and residue-free pest control.
• New guidelines for rice harvest and drying have been widely adopted, reducing discoloration and preserving quality across 15+ million bushels. Nearly 100 growers now use EMC-based sensors for automated bin monitoring.
• New simulations improve detection and traceability of contaminated grain in storage, enhancing safety and recall procedures.
• Research supports food-grade applications of Intermediate Wheatgrass through strategic nitrogen use, aiding its market development as a sustainable grain.
• Studies show combine-sampling yields more consistent DON estimates than hand-sampling, informing future FHB and DON management guidelines.
• Research is improving soybean storage guidance under high-temperature, high-humidity conditions, especially for low-latitude regions.
• Innovations in radio-frequency processing help convert corn fiber into health-focused supplements and feed products, boosting Indiana corn’s market value.
• Early success in granulating Spent Brewer’s Grains points to potential new feed options, with further research planned on binders and microbiological safety.
• Researchers at Iowa State University completed a comprehensive life cycle assessment (LCA) of the U.S. corn wet milling industry, filling a critical knowledge gap with up-to-date environmental impact data for HFCS55 and other co-products. The study identified a potential 20% reduction in environmental impact if coal is replaced by natural gas in cogeneration systems.
• Commissioned and operationalized the Iowa State University (ISU) Kent Feed Mill and Grain Science Complex, a state-of-the-art facility featuring a self-contained feed manufacturing tower, pilot plant, warehouse, quality lab, classroom, and a full grain handling center. This facility supports ISU’s missions in research, teaching, service, extension, and global industry engagement.
• Launched the “Training the Next Generation of Leaders for a Transforming Grain Industry” project, establishing a scholar cohort across six institutions. The group participates in bi-weekly seminars on grain and feed handling and processing, and a Master of Science program is under development for a 2025 rollout.
• The life cycle assessment increased industry and academic understanding of environmental impacts tied to HFCS55 production. The findings support future efforts to enhance sustainability across the corn wet milling supply chain.
• The ISU Feed Mill served as a hub for international collaboration and industry training, empowering professionals from across the globe with practical knowledge and certifications in feed safety, operations management, and quality assurance.
• The “Training the Next Generation” initiative is cultivating future experts by building a shared curriculum and institutional network to offer a cross-institutional graduate program in grain and feed systems, responding to long-term workforce needs in the sector.

Accomplishments

NC-213 Accomplishments and Impact Statement Advancing Grain Quality, Food Safety, and Value Across the U.S. Grain Supply Chain Summary The NC-213 U.S. Quality Grains Research Committee advanced innovative technologies, predictive tools, and sustainable processing strategies that improved grain quality, food safety, storage management, and value-added utilization of grains and oilseeds across the United States. Through multi-institutional collaborations involving universities, USDA-ARS, industry partners, and international stakeholders, the committee developed practical solutions that reduced postharvest losses, improved food and feed safety, enhanced grain processing efficiency, and strengthened market opportunities for emerging grain products and coproducts.   Situation Grain and oilseed industries face increasing challenges related to postharvest losses, food and feed safety, climate variability, insect and fungal contamination, declining storage efficiency, and growing demand for sustainable, high-quality, and nutritious grain-based products. Traditional grain monitoring and quality assessment methods are often labor-intensive, slow, and reactive rather than predictive. In addition, producers and processors require improved tools to manage risks associated with aflatoxins, mycotoxins, storage deterioration, veterinary drug carryover, and off-odor development in stored grains. Simultaneously, consumers and food manufacturers are demanding more functional, plant-based, and nutritionally enhanced grain ingredients, while supply chains seek better economic efficiency and reduced waste. These challenges directly affect grain producers, feed manufacturers, processors, exporters, food companies, regulators, and consumers across domestic and international markets.   Accomplishments NC-213 researchers implemented coordinated, multi-state research and outreach programs to improve grain quality management, processing technologies, and food safety systems across the grain supply chain. Key accomplishments included: <ul> <li>Development of advanced food safety and quality management systems for feed mills to reduce veterinary drug carryover and improve compliance with FDA Food Safety Modernization Act regulations. Researchers developed rapid tracer-based screening methods and carryover prediction tools for feed manufacturing systems.  </li> <li>Creation of predictive machine learning models and decision-support systems for stored grain management that integrated sensor-based monitoring data with economic loss estimation, allowing producers and grain elevators to better manage grain quality deterioration and financial risks during storage.  </li> <li>Evaluation and promotion of stored grain monitoring technologies and AI-enabled actionable decision-support frameworks to improve adoption of smart grain management systems among farmers and grain elevators.  </li> <li>Development of low-cost, sustainable postharvest protection strategies, including oxygen-scavenging hermetic storage systems and botanical nanoemulsion fumigants that achieved rapid insect mortality while preserving grain quality without synthetic pesticides.  </li> <li>Advancement of rapid grain quality diagnostic methods such as GlutoPeak testing for high-throughput screening of wheat gluten functionality and end-use quality, improving efficiency in breeding and grain quality evaluation programs.  </li> <li>Development of science-based quality metrics for emerging crops such as industrial hemp and perennial grains, including Kernza®, to support breeding, processing optimization, commercialization, and expansion of sustainable grain markets.  </li> <li>Improvement of feed and food safety through enhanced analytical methods for vitamin D quantification, aflatoxin risk prediction models, proficiency testing programs, and international grain safety collaborations in Africa and other global regions.  </li> <li>Investigation of grain composition, dietary fiber functionality, and protein extraction technologies to support development of high-value plant-based ingredients and functional foods derived from maize bran, alfalfa seed, hemp, and other grain crops.  </li> </ul>
