Abstract

The invention discloses fruit juice lactic acid natural yeast. The fruit juice lactic acid natural yeast is prepared in steps as follows: components including, in parts by weight, 7-10 parts of raisin, 13-16 parts of banana peels, 22-25 parts of corn juice and 15-18 parts of yogurt are mixed and put in a disinfected glass bottle, 17-20 parts of distilled water and 4-7 parts of maltitol are added, the mixture is uniformly stirred, the glass bottle is sealed, heating and thermal insulation are performed, 3-6 parts of honey are added, the mixture is uniformly stirred and subjected to thermal insulation, and the fruit juice lactic acid natural yeast is obtained. The invention further discloses an application method of the fruit juice lactic acid natural yeast in brewing of the grape wine. The fruit juice lactic acid natural yeast has high nutritional value and stable quality, can be preserved for a long time and is not prone to mildewing; the prepared grape wine tastes fine and has sufficient fruity flavor, heavy fragrance and good quality, the fermentation speed is high, breeding of contaminating microorganisms is avoided, the fermentation quality of raw wine is improved, and the nutritional value is higher.

Description

technical field [0001] The invention relates to the technical field, in particular to a fruit juice lactic acid natural yeast and its application method in wine brewing. Background technique [0002] Natural yeast refers to the yeast made by natural fermentation with some natural ingredients. At present, the domestic natural yeast has low nutritional value, unstable quality, short shelf life, and easy loss of yeast activity. At present, the cost of yeast used in wine fermentation is relatively high, the fermentation speed of wine is slow, and the fermentation time is long, which is used to cause the reproduction of miscellaneous bacteria. Not rich enough. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a fruit juice lactic acid natural yeast and its application method in wine brewing, which has high nutritional value, stable quality, long storage time, and is not easy to mold, and th...
