A production method of a Huai Chinese yam yellow rice
wine comprises the steps: selecting Huai Chinese yam and black glutinous rice with the
mass of 2-3 times that of the Huai Chinese yam, and then respectively cooking; adding water into the cooked Huai Chinese yam, breaking up into a pulp, adding alpha-
amylase, carrying out heat preservation at the temperature of 80-100 DEG C for 1-2 hours, allowing to carry out
liquefaction enzymolysis, and thus obtaining a pulp after enzymolysis; adding the cooked black glutinous rice to the pulp after enzymolysis, and then adding
fermentation yeasts and an acidic
protease; again uniformly mixing, carrying out primary
fermentation and post
fermentation, after fermentation is finished, filtering the fermented mash by a plate and frame filter, and thus obtaining a fermented
wine liquid; and carrying out
pasteurization on the filtered
wine liquid at the temperature of 88 DEG C for 25 minutes, and thus obtaining the Huai Chinese yam yellow rice wine. The black glutinous rice and the Huai Chinese yam are used as the raw materials for fermentation, and the prepared Huai Chinese yam yellow rice wine has the
ammoniacal nitrogen content of up to 0.7-1.5 g / L, the
antioxidant activity equivalent to 0.15-0.3 g / L of
vitamin C, the
alcohol degree of up to 14% and the
sugar content as low as 0.7-2.0 g / L, is clear, transparent and glossy in sensory evaluation, coordinative in wine body and good in taste, and is fresh, brisk and mellow.
