Chemical Compositions of Edamame Genotypes Grown in Different Locations in the US

The consumption of edamame [ Glycine max (L.) Merr.] in the US has rapidly increased due to its nutritional value and potential health benefits. In this study, 10 genotypes were planted duplicates three different locations US—Whitethorne, Virginia (VA), Little Rock, Arkansas (AR), Painter, VA. Edamame samples harvested at R6 stage bean development when beans filled 80–90% pod cavity. Afterward, comprehensive chemical composition analysis, including sugars, alanine, protein, oil, neutral detergent fiber (NDF), starch, ash, moisture contents, conducted on powdered using standard methods total sweetness was calculated based measured sugars alanine contents. Significant effects location observed all constituents ( p < 0.05). average performance higher Whitethorne for contents free sucrose (59.29 mg/g), fructose (11.42 glucose (5.38 raffinose (5.32 stachyose (2.34 (78.63 starch (15.14%) compared Rock Painter. highest soluble (2.67 NDF (9.00%), ash (5.60%), (70.36%) found while Painter had crude protein (43.11%) oil (20.33%) genotype most 0.05) except raffinose.
