Abstract

The invention relates to the technical field of fruit wine brewing, in particular to a method for clarifying fruit wine by using a microbial leavening agent. The method mainly comprises the following steps: adding a proper amount of sulfur dioxide into fruit juice, sequentially adding lactic acid bacteria for producing exopolysaccharides, and carrying out constant-temperature static fermentation; adding bottom beer yeasts and performing constant-temperature static fermentation; adjusting the sugar degree of the fermented wine liquid according to the sugar degree of the fruit juice and the alcoholic content of the finished fruit wine, and adjusting the pH value of the fermented wine liquid to 4.0-5.5; and adding fruit wine yeasts and carrying out constant-temperature static fermentation until the weight of the fermented wine is not changed any more. While the alcoholic fermentation of the fruit wine is completed, the colloidal suspended substances in the fruit wine can be effectively reduced, and the clarity and the stability of new wine are improved; the technical difficulty and production cost of the clarification process are reduced, the clarification treatment time is shortened, flavor or nutrition loss is avoided, the production efficiency of the fruit wine is improved, the acidity of the fruit wine can be reduced through lactic acid bacteria fermentation, and the fruit wine is endowed with richer taste and flavor.

Description

technical field [0001] The invention relates to the technical field of fruit wine brewing, in particular to a method for clarifying fruit wine by utilizing a microbial fermentation agent. Background technique [0002] The fruit wine brewed by microbial fermentation technology contains yeast, bacteria, protein, tannin and berry tissue fragments in the new wine obtained after the alcoholic fermentation, which will cause turbidity and discoloration of the fruit wine during storage, seriously affecting The quality of fruit wine and the development of fruit wine industry. Therefore, the new wine after alcoholic fermentation must be clarified to obtain stable and excellent quality. The clarification methods commonly used in modern times mainly include heat treatment, freezing treatment, membrane filtration technology, clarifying agent, mechanical treatment, enzyme preparation clarification method, etc. [0003] Application number: CN202011543391.3 Chinese invention "A kind of wo...
