Fruit vinegar brewed by using grape skins

Abstract

The invention relates to table vinegar, and in particular relates to fruit vinegar brewed by using grape skins. The fruit vinegar is brewed by the following steps: grinding the grape skins into a pulp to obtain a fruit skin pulp; inoculating cellulase of which the weight accounts for 2-2.3% of that of the fruit skin pulp; after culturing for 98-100 hours, inoculating hemicellulase of which the weight accounts for 2-2.3% of that of the fruit skin pulp; after culturing for 48-50 hours, adding ethanol of which the weight is 2-3 times that of the fruit skin pulp and citric acid of which the weight accounts for 2-2.5% of that of fruit skins; leaching for 1-1.5 hours under microwaves with the power of 220-240W; centrifuging a leaching solution to obtain a supernatant; heating the supernatant to 85-90 DEG C; performing heat-preservation stirring for 1-2 hours, and introducing oxygen into the supernatant at a rate of 2L / min while stirring; after stirring adding molasses of which the weight accounts for 20-22% of that of the fruit skins, and inoculating monascus of which the weight accounts for 0.2-0.5% of that of the grape pulp; culturing for 30-40 hours; treating for 4-6 minutes under microwaves with the power of 520-550W; adding tangerine peels of which the weight accounts for 3-5% of that of a grape pomace pulp; sealing and storing at a ventilating place for more than or equal to 3 months; and filtering residues to obtain the fruit vinegar.
