Method for brewing health-care vinegar drink by using wolfberry grape pomace

Abstract

The invention discloses a method for brewing a health vinegar beverage by using wolfberries and grape skin pomace. The method comprises the steps of raw material treatment, mixing, alcoholic fermentation, acetic fermentation, filtration after acetic fermentation, ageing, blending, filtering after blending, bottling and sterilization. According to the method, fresh wine grape pomace from a red variety is adopted, alcoholic fermentation is carried out by adopting residual active yeast and sulfur dioxide in the fresh pomace, and the yeast or the sulfur dioxide is not added any more, so that the process is simplified and the cost is reduced. The fresh red grape pomace and the wolfberries contain multiple effective ingredients with a health effect on a human body; and the wolfberries are mixed with the grape pomace for fermentation after ultra-micronization, so that the dissolved amount of the effective ingredients is increased, absorption of health ingredients is facilitated through interaction, the health effect of the vinegar beverage is strengthened, the vinegar beverage has the effects of resisting oxidation, softening blood vessels, nourishing the liver and kidneys, replenishing vital essence to improve eyesight, maintaining beauty and keeping young, the health vinegar beverage is bright in color and luster, elegant in aroma, and sour, sweet and delicious in taste.

Description

technical field [0001] The invention relates to the technical field of fruit vinegar brewing, in particular to a method for brewing a health-care vinegar beverage by using wolfberry grape pomace. Background technique [0002] At present, in the production process of wine brewing in my country, about 600 million tons of grape pomace are produced every year, and these grape pomace contain useful substances with health care value. Grapes are rich in polyphenols, mainly distributed in the skin. The polyphenol content in the skin of red grapes can reach 25% to 50%, and the content in the seeds can reach 50% to 70%. The peel mainly contains anthocyanins, resveratrol and flavonoids, and the grape seeds mainly contain catechins, quercetin, proanthocyanidins and tannins. Polyphenols are powerful antioxidants that can resist aging, lower blood lipids and cholesterol, and soften blood vessels; resveratrol can prevent healthy cells from becoming cancerous and prevent cancer cells from...

Problems solved by technology

The above-mentioned prior art has the following technical problems: 1. The dried grape pomace will inactivate the yeast, and yeast needs to be added during the brewing process, which increases the cost; The grape pomace needs to add sulfur dioxide during the brewing process. Improper or excessive use of sulfur dioxide will cause sulfurous acid odor and increase the rough feeling. Excessive use will be harmful to the human body
