Problems solved by technology

[0004] Now the blueberry production period is concentrated, the price is expensive, and it is difficult to control the changes in the total sugar and total acid of blueberry wine during the brewing process. While controlling the changes in the total sugar and total acid of blueberry wine, it is necessary to control the blueberry wine to meet the quality requirements. It meets the taste requirements of the product, and the processing cost must also be considered comprehensively, which increases the difficulty of brewing, and the acidity of domestic blueberry varieties is generally high, so it is more difficult to brew blueberry wine with a suitable taste and moderate sweetness
[0005] At the same time, the current blueberry wine brewing method mostly uses jam to brew, so that the blueberry wine obtained by brewing has a low anthocyanin content; and the current brewing method mostly uses normal temperature fermentation, so that the blueberry wine obtained by brewing contains more Sediment and suspended matter, the body of the wine is not clear, affecting the taste, and adding bentonite to precipitate and filter the suspended matter will introduce chemical substances and reduce the nutritional value of blueberry wine; in addition, SO is often added in the current brewing process 2 , sodium sulfite and other substances for sterilization, but the added chemical substances reduce the nutritional value of blueberry wine, and drinking it will affect human health

Abstract

The invention relates to the technical field of fruit wine brewing, in particular to sweet blueberry wine and a brewing process thereof. The brewing process comprises steps as follows: (1) selection and washing of fresh blueberries; (2) freezing; (3) unfreezing and breaking: primary sugar adjustment is performed during breaking; (4) addition of pectase; (5) secondary sugar adjustment and addition of yeast; (6) fermentation at controlled temperature; (7) addition of a yeast auxiliary; (8) separation of peel and pomace; (9)ageing; (10) primary filtering; (11) primary freezing and primary unfreezing; (12) secondary freezing and secondary unfreezing; (13) secondary filtering; (14) ultraviolet sterilization. The brewing process is simple in operation, no chemical substances are added, the sweet blueberry wine is healthy and harmless, the wine is brewed with a blueberry freezing method, the sugar content of the finished blueberry wine is increased, and the wine is clearer; the content of anthocyanin of the blueberry wine is increased and the nutritional value is improved with the adoption of whole berry fermentation.

Description

technical field [0001] The invention relates to the technical field of fruit wine brewing, in particular to a sweet blueberry wine and a brewing process thereof. Background technique [0002] Blueberry wine is brewed from blueberries through multiple processes. It not only retains the nutrients of blueberries, such as anthocyanins, selenium, amino acids, vitamins, calcium, phosphorus, iron, zinc and other nutrients, but is more easily absorbed by the human body. , and the mouthfeel of blueberry wine is more attractive than common blueberry fruit and blueberry juice, and is widely liked by people. [0003] The anthocyanins in blueberries are pure natural anti-aging nutritional supplements. Studies have shown that they are the most effective antioxidants found by humans today. Its antioxidant properties are fifty times higher than vitamin E and two times higher than vitamin C. It has the functions of enhancing eyesight, eliminating eye fatigue, delaying the aging of brain ner...
