Description

Method for producing plum wine by four-stage fermentation and plum wine product
[ technical field ] A method for producing a semiconductor device
The invention relates to a method for producing plum wine by four-stage fermentation and a product thereof.
[ background of the invention ]
Before the plum fruit is ripe, it is called green plum, and after the plum fruit is ripe and becomes yellow, it is called yellow plum. The mume fructus is rich in saccharide, fat, protein, vitamin A, vitamin B1, vitamin B2, vitamin C, calcium, ferrum, potassium, phosphorus, malic acid, citric acid, tartaric acid, fiber, etc. The protein content of plum is also higher than that of other fruits, and the content of calcium, iron, magnesium and zinc is 4 times, 6 times, 7 times and 5 times of that of apple respectively. The plum is also rich in organic acids, flavonoids, polyphenols and other substances, and is helpful for human health.
Most of plum wine produced in the market at present is prepared by a soaking (steeping) mode, and the manufacturing process of common steeping plum wine comprises the following steps: soaking mume fructus in Chinese liquor and crystal sugar for several months after killing cyanine and pricking cortex, separating condensate, and bottling; or soaking in 50-60% alcohol for two weeks without adding sugar, adding 25-30% sugar, and separating the condensate to obtain the soaked plum wine. It is seen that the preparation period of the existing plum wine is long, and sulfur dioxide (sulfite) is often added to inhibit the contamination of infectious microbes in general wine brewing. In addition, the plum is soaked by white spirit/high-concentration alcohol, and the white spirit is prepared by grain production and distillation, so that the grain and energy waste and high cost are realized; in addition, plum wine soaked with high concentration alcohol is severely browned.
