Method for preparing rice vinegar from rice residue of rice wine, and rice vinegar

Abstract

The invention discloses a method for preparing rice vinegar from rice residue of rice wine, and the rice vinegar. The method comprises the steps that the rice residue of the rice wine is crushed, subjected to size mixing, liquefied, boiled, saccharified, subjected to alcoholic fermentation, filtered, acetic fermentation and after-ripening, ultra-filtered, blended and sterilized and stored, fillingis conducted, and then a finished product is formed. Through by-products generated in the fermentation process of the rice wine, the problems that the utilization rate of the rice wine residue is nothigh, wasteness is large, and the utilization rate of proteins is not high are solved, nutritional ingredients in the wine residue are increased and utilized, meanwhile the problem that rice wine residue pollution caused by discarded rice can also be solved, and the productive profit of rice wine plants is increased.
