Preparation method of zinc-enriched grape wine

Abstract

The invention mainly relates to the technical field of food processing and discloses a preparation method of zinc-enriched grape wine. The preparation method comprises the following steps: preparing raw materials; carrying out primary fermentation; carrying out secondary fermentation; carrying out tertiary fermentation; packaging. The obtained zinc-enriched grape wine has a clear wine body and abundant nutrients, is sour and sweet and palatable and has a rich fruit aroma; the zinc content reaches 6.37mg/100g; the variety of grape wine in the market is enriched, and the requirements on nutrients and mouthfeel of consumers are met; grape leaves are added into grape pulp and wastes are changed into valuable materials; nutrients and flavor of the grape wine are increased; the multiplication ofthalli is promoted through the primary fermentation and late fermentation is facilitated; after the primary fermentation is carried out, white granulated sugar and protein zinc are added, and the temperature is reduced to carry out the secondary fermentation, so that bright color and luster of grapes are kept, a bitter mouthfeel of the grape leaves is removed, the aroma is increased and the mouthfeel is full; after the secondary fermentation is carried out, the temperature is continually reduced to carry out the tertiary fermentation, so that all nutrient substances are sufficiently fused andthe mouthfeel is soft; low-temperature ageing is carried out after filtering,; the wine body keeps clear and the shelf life of the grape wine is prolonged.

Description

technical field [0001] The invention mainly relates to the technical field of food processing, in particular to a preparation method of zinc-rich wine. Background technique [0002] Grapes are sweet and sour, nutritious, and loved by people, but few people eat grape leaves, which are rich in vitamins, tartaric acid, malic acid, oxalic acid, fumaric acid, succinic acid, citric acid, quinic acid, shikimic acid, glycerin Acid, isoquercitrin, quercetin and rutin can stop bleeding and reduce swelling, clear away heat and heat, moisten the lungs and relieve cough, treat eye diseases, and promote gastrointestinal function. They have high nutritional and health value. Making grapes into wine is A traditional deep-processing method of grapes. There are many varieties and brands of wine on the market, but very few zinc-rich wines can't meet the health care needs of consumers. Contents of the invention [0003] In order to remedy the defects of the prior art, the purpose of the inve...
