Abstract

The invention discloses a method for preparing fresh rice wine by utilizing ultrasonic sterilization. The method mainly comprises the following steps: 1) processing glutinous rice to obtain cooked glutinous rice; 2) uniformly mixing the cooked glutinous rice with koji accounting for 0.1-0.3% of the weight of the glutinous rice, conducting fermenting at 28-30 DEG C for 2-3 days, adding water with aweight 1-4 times the weight of the glutinous rice, conducting uniform stirring, continuing fermentation for 2-7 days, stopping fermentation, and carrying out separating to obtain a fermented wine liquid; and 3) placing the fermented wine liquid in an ultrasonic sterilization machine for sterilization treatment to obtain the fresh rice wine, wherein ultrasonic power is 40-200 W, treatment temperature is 20-40 DEG C, and treatment time is 5-20 min. According to the invention, sucrose invertase in the rice wine is not inactivated by heating in virtue of ultrasonic sterilization, so compared withexisting rice wine, the rice wine of the invention has the advantages of fresh taste, delicious taste and rich nutrition, and the contradiction that the rice wine is not fresh in taste and cannot bestored for a long time while the freshness of the taste is ensured is solved. The invention provides a novel rice wine category conforming to the health concept of modern consumers.
