The invention discloses a method for preparing sugarcane juice
flavor vinegar, which comprises the following steps of: cleaning sugarcane, pressing, and performing
solid-liquid separation and other treatment to obtain clarified sugarcane juice, and preparing into a
fermentation medium; introducing
yeast culture solution for alcoholic
fermentation, wherein the introduced volume is 2 to 10 percent based on an initial volume of the alcoholic
fermentation, and fermenting at the temperature of between 28 and 32 DEG C for 72 to 120 hours; finishing the alcoholic fermentation and introducing
acetobacter culture solution, wherein the introduced volume is 5 to 10 percent based on the initial volume of acetic fermentation, performing submerged
aeration fermentation, controlling the
aeration amount to be 0.06 to 0.12L / (L*min), controlling the temperature to be between 28 and 32 DEG C, fermenting for 144 to 240 hours and finishing the acetic fermentation; and finally performing
solid-liquid separation on fermenting mash, and conventionally sterilizing to prepare the sugarcane juice
flavor vinegar. The prepared sugarcane juice
flavor vinegar has the characteristics of rich
aroma, soft sour, full
mouthfeel and the like, can be used as a novel leading product of a sugarcane resource, and brings a novel economic
growth point to the sugarcane industry.
