Edible Qualities and Flavor Omics of Peanut-Soybean Dajiang. [PDF]

Food Sci Nutr
Dajiang is a fermented beans‐based condiment that is widely popular in Northeast China. In this study, peanut‐soybean Dajiang was successfully prepared by adding peanut to the Dajiang production process and optimizing the fermentation conditions. It was found that the addition of peanuts significantly enhanced the umami, saltiness and compound taste of
