effect of planting date and cultivar maturity in Edamame quality and harvest window
Frontiers in Plant Science, 2021Co-Authors: David Moseley, Marcos P Da Silva, Leandro Mozzoni, Moldir Orazaly, Liliana Florezpalacios, Andrea Acuna, Pengyin ChenAbstract:Edamame is a food-grade soybean [Glycine max (L.) Merr.] that is harvested immature between the R6 and R7 reproductive stages. To be labeled as a premium product, the Edamame market demands large pod size and intense green color. A staggered harvest season is critical for the commercial industry to post-harvest process the crop in a timely manner. Currently, there is little information to assist in predicting the optimum time to harvest Edamame when the pods are at their collective largest size and greenest color. The objectives of this study were to assess the impact of cultivar, planting date, and harvest date on Edamame color, pod weight, and a newly minted Edamame Harvest Quality Index combining both aforementioned factors. And to predict Edamame harvest quality based on phenological stages, thermal units, and planting dates. We observed that pod color and weight depended on the cultivar, planting date, and harvest date combination. Our results also indicated that Edamame quality is increased with delayed planting dates and that quality was dependent on harvest date with a quadratic negative response to delaying harvest. Maximum quality depended on cultivar and planting and harvest dates, but it remained stable for an interval of 18-27 days around the peak. Finally, we observed that the number of days between R1 and harvest was consistently identified as a key factor driving Edamame quality by both stepwise regression and neural network analysis. These research results will help define a planting and harvest strategy for Edamame production in Arkansas and the United States Mid-South.

quality of acid preserved Edamame soybean at immature and mature stages
Frontiers in Sustainable Food Systems, 2020Co-Authors: David Moseley, Leandro Mozzoni, Moldir Orazaly, Liliana Florezpalacios, Pengyin ChenAbstract:Edamame is a food-grade soybean that is harvested at the green-immature stage (R6) and sold fresh or frozen for consumption after steaming or boiling. Limited studies have been conducted on high-temperature sterilization of Edamame in cans and on acid preservation of Edamame. The objectives of this study were to evaluate the color retention and texture of Edamame when pasteurized in acidic brine as compared to boiling, to assess the effect of sucrose and turmeric addition on acid-treated Edamame, and to characterize varietal differences when Edamame lines were pasteurized in an acidic brine at either R6 or R8 stage. All studies were conducted using industry-standard processing conditions for acid-preservation of food in glass containers. The results of this research indicated that acid processing caused losses in intensity of green color and hue, but much smaller than those reported when heat-processing Edamame in cans. We also observed a small and borderline significant increase in texture (p=0.0790) in acid-preserved samples. In addition, we found that green color is positively affected by the addition of turmeric to the brine, but not of sucrose. Finally, the varieties R07-589 (red-brown seed coat) and R09-345 (black seed coat) acid-processed at R8 had color and texture similar to canned in-kind substitute products. In conclusion, acid-preservation, and addition of turmeric to immature Edamame, helped maintain an acceptable quality of the processed products.

information and order of information effects on consumers acceptance and valuation for genetically modified Edamame soybean
PLOS ONE, 2018Co-Authors: Ji Yong Lee, Elijah Wolfe, Michael P Popp, Rodolfo M Nayga, Jennie Popp, Pengyin Chen, Hanseok SeoAbstract:This study examines two different strategies with respect to managing the order in which information about genetically modified (GM) technology would reach and impact consumers of Edamame, often referred to as the “vegetable soybean”. Edamame are soybeans harvested while the beans are young and soft. We capture consumers’ willingness to pay (WTP) for unlabeled Edamame, non-GM Edamame, and GM Edamame using a non-hypothetical random nth price auction. We elicit consumers’ valuation for each Edamame product before and after introducing information, and test two strategies where the order of providing positive and negative information is reversed. The results suggest that negative information affects WTP to a much greater extent than positive information. Hence a strategy to proactively deal with eventual negative press about GM technology did not lead to a different result than a strategy that would react to or attempt to thwart negative information with positive information at a later date. These findings suggest that it would be difficult to introduce new GM Edamame as edible products in the market as marginally negative preconceptions about GM at the time of the experiment were easier to reinforce with negative information than to combat with positive information about GM.

consumers willingness to pay for Edamame with a genetically modified label
Agribusiness, 2018Co-Authors: Elijah Wolfe, Michael P Popp, Claudia Bazzani, Rodolfo M Nayga, Diana M Danforth, Jennie Popp, Pengyin Chen, Hanseok SeoAbstract:Results from a sensory test of Edamame, which is soybean (Glycine max (L.) Merr.) harvested near the end of the pod filling stage, followed by a non-hypothetical auction, and finally a questionnaire were used to determine WTP for GM labeled Edamame in comparison to unlabeled and non-GM labeled Edamame. The results showed a significant price premium for non-GM Edamame even though overall sensory impression did not differ between GM and non-GM Edamame. Interestingly unlabeled and GM labeled Edamame bids were similar suggesting that consumers wanted to be informed. Preconceived consumer notions appeared to play a role as did knowledge, opinion, income, and consumption frequency in subsamples of respondents. Labeling Edamame is in the interest of producers as all Edamame produced in the U.S. is non-GM.

THE DEVELOPMENT OF A LEXICON FOR FROZEN VEGETABLE SOYBEANS (Edamame)
Journal of Sensory Studies, 2006Co-Authors: B.f. Krinsky, Maryanne Drake, Gail Vance Civille, Lisa L. Dean, K.w. Hendrix, Timothy H. SandersAbstract:American vegetable soybean (Edamame) consumption is limited, but potential for increased markets based on U.S. production is high. Vegetable soybeans (Glycine max. [L.] Merrill) are harvested while the seeds are still immature. Because of limited harvesting time, freezing is essential for year-round availability of Edamame. A lexicon to identify and define the aromatics, tastes and feeling factors for Edamame was created using a total of 20 shelled and in-pod samples of commercial frozen Edamame. The Edamame lexicon development was initiated by a commercial sensory company, further developed by a 12-member panel of flavor and/or soybean specialists and finalized by a trained sensory panel. Intensity ratings, based on the Spectrum descriptive analysis method, were assigned to terms in the lexicon. References that exemplified the terms were obtained and evaluated for applicability by the panel. Edamame flavor was described by 13 aromatic attributes, three feeling factors and the basic tastes that were subsequently used by a trained descriptive panel to demonstrate the usefulness of the terms and intensities on a subset of the original commercial samples and limited samples from a blanching study using freshly harvested vegetable soybeans.
