Abstract

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.
