A1
Abstract:
Disclosed are a multi-strain liquid fermented vinegar rich in lactic acid and acetoin, and a brewing method therefor. The brewing method comprises: firstly, soaking and cooking rice or sticky rice; adding water and then adding a liquifying enzyme and a saccharifying enzyme to obtain a saccharification liquid; inoculating with Saccharomyces cerevisiae for fermentation to obtain a mash; mixing bran with water, and then filtering the mixture to obtain a bran leaching solution; inoculating with Lactobacillus helveticus to obtain a lactic acid fermentation broth; mixing the mash with the lactic acid fermentation broth, and inoculating with Acetobacter pasteurianus and Gluconacetobacter xylinum for acetic fermentation to obtain a vinegar liquor rich in acetoin; and then adding saccharose and inoculating with fermented Lactobacillus acetotolerans for anaerobic fermentation to obtain the liquid fermented vinegar rich in acetoin and lactic acid.
