    Cyberbiosecurity: A New Perspective on Protecting US Food and Agricultural System
    Duncan, Susan E.; Reinhard, Robert; Williams, Robert C.; Ramsey, A. Ford; Thomason, Wade E.; Lee, Kiho; Dudek, Nancy; Mostaghimi, Saied; Colbert, Edward; Murch, Randall Steven (Frontiers, 2019-03-29)
    Our national data and infrastructure security issues affecting the "bioeconomy" are evolving rapidly. Simultaneously, the conversation about cyber security of the U.S. food and agricultural system (cyber biosecurity) is incomplete and disjointed. The food and agricultural production sectors influence over 20% of the nation's economy ($ 6.7T) and 15% of U.S. employment (43.3M jobs). The food and agricultural sectors are immensely diverse and they require advanced technologies and efficiencies that rely on computer technologies, big data, cloud-based data storage, and internet accessibility. There is a critical need to safeguard the cyber biosecurity of our bio economy, but currently protections are minimal and do not broadly exist across the food and agricultural system. Using the food safetymanagement Hazard Analysis Critical Control Point systemconcept as an introductory point of reference, we identify important features in broad food and agricultural production and food systems: dairy, food animals, row crops, fruits and vegetables, and environmental resources (water). This analysis explores the relevant concepts of cyber biosecurity from food production to the end product user (such as the consumer) and considers the integration of diverse transportation, supplier, and retailer networks. We describe common challenges and unique barriers across these systems and recommend solutions to advance the role of cyber biosecurity in the food and agricultural sectors.

    Sensory and Consumer Studies in Plant Breeding: A Guidance for Edamame Development in the U.S.
    Carneiro, Renata C. V.; Duncan, Susan E.; O'Keefe, Sean F.; Yin, Yun; Neill, Clinton L.; Zhang, Bo (Frontiers, 2020-08-19)
    Plant breeding is an important discipline to develop food products and improve overall quality, chemical composition, and nutritional value of crops, vegetables, fruits, and nuts, which can be important allies in health promotion. Apples, blueberries, wine grapes, tomatoes, and peanuts are a few examples of food products that were improved in past decades through plant breeding programs in the United States. Recently, edamame (vegetable soybean) has gained special attention from breeders, non-breeder researchers, growers, and consumers, and new edamame varieties are currently being developed for domestic production. As a popular nutritious crop in Asian countries, edamame is increasing in sales and consumption in the United States. Therefore, edamame has great potential to be a profitable alternative crop to replace tobacco farming, whose production and market value have been declining. Until the present date, most published reviews on edamame have focused on its agronomic characteristics. However, understanding consumer expectations, needs, and acceptability for new and improved crops like edamame is vital to guide and sustain their production. It is important that researchers working on plant breeding programs understand and consider the aspects that are relevant for both growers and consumers (e.g., crop productivity, pest and disease resistance, nutritional properties, and sensory attributes). Thus, this review paper aims to integrate available information on sensory quality of edamame and to support its development and production in the United States. This review presents an overview of how sensory evaluation and consumer studies have been used to support plant breeding programs in the development of alternative crops, such as edamame.

    Utilizing Consumer Perception of Edamame to Guide New Variety Development
    Carneiro, Renata C. V.; Duncan, Susan E.; O'Keefe, Sean F.; Yu, Dajun; Huang, Haibo; Yin, Yun; Neill, Clinton L.; Zhang, Bo; Kuhar, Thomas P.; Rideout, Steven L.; Reiter, Mark S.; Ross, W. Jeremy; Chen, Pengyin; Gillen, Anne (2021-01-18)
    Consumption of edamame (vegetable soybeans) has increased significantly in the U.S. over the last 20 years. Although market demand has been increasing, most edamame is still imported from Asian countries. A team of multistate plant-breeding programs in the mid-Atlantic and Southeast U.S. has focused on developing new breeding lines that grow well in the U.S. and deliver what domestic growers, processors and consumers need and expect from their edamame. In our study, sensory evaluation was used to identify edamame genotypes and sensory attributes preferred by consumers to support breeding selection criteria. In the first year (reported as our "screening study"), 20 edamame genotypes were grown in three locations: Newport, AR, and Blacksburg and Painter, VA. In the second year (reported as our "validation study"), 10 edamame genotypes selected after our screening study were grown in Blacksburg and Painter, VA, Portageville, MO, and Stoneville, MS. In both years of research, untrained participants (adults; vegetable consumers not allergic to soy; N >= 50) used a traditional 9-point acceptability (hedonic) scale (1 = "dislike extremely"; 9 = "like extremely") to evaluate overall-liking, aroma, appearance, taste, and texture, and a 5-point scale (1 = "not sweet," 5 = "extremely sweet") to evaluate sweetness intensity. Next, participants used a check-all-that-apply (CATA) list of selected sensory terms to describe the sensory characteristics of each edamame sample. Overall acceptability of edamame genotypes was significantly different among all genotypes (p < 0.05). Samples described as "bitter," "sour" (flavor) or "starchy" (texture) were associated with lower acceptability scores while "salty" and "sweet" (flavor) were correlated with higher acceptability. Sensory data from the screening study were used to select the best genotypes by use of a defined decision process based on the consumer data. The validation study tested the selection decisions and further supported the genotype choices. Sensory evaluation is a powerful tool to direct breeders to improve market acceptability and develop new edamame genotypes. Both screening and validation studies illustrate the significant role of consumer sensory data in support of genotypes targeted for domestic (U.S.) production.
