Abstract

|
Applying ginger to processed foods to improve health is limited due to its pungent odor. In this study, fermented gingers were prepared using lactic acid bacteria from dairy products or kimchi and their chemical and sensory properties were examined. Adding dried ginger or fermented gingers (GSt, GLa, GLm) to plain yogurt made them less tasty and lowered the overall acceptability of yogurt except GLp. For all fermented gingers including GLp, the characteristic flavors of the ginger decreased by fermentation so adding fermented ginger into yogurt did not affect its flavor significantly. Thus GLp would be expected to be a food ingredient instead of dried ginger without lowering organoleptic qualities. The content of 6-gingerol, a bioactive component in ginger, decreased in all fermented gingers. However, 6-shogaol, which increased in GSt, GLa, and GLm, was not detected in GLp.
