Method of making wine by red dates fermentation

Abstract

A method of making a wine by red dates fermentation comprises choosing fresh red dates, making dates pulp, adding 0.02 g / L of pectinase, separating to obtain dates juice and filtrate, adding citric acid to the dates juice for use, micro-electrolyzing non-heated dates juice with a voltage of 100 volts, culturing at the constant temperature of 40 DEG C to obtain a strain, blending the dates juice and the strain in a mass ratio of (40-50):1, stirring well, adding an activated yeast accounting for 0.04-0.06% by mass of the dates juice and a humate accounting for 0.01-0.02%, stirring well in a fermenting tank, sealing, holding the temperature of 18-24 DEG C, fermenting for 15-35 days, adding pectinase, clarifying at 50-60 DEG C for 12 h, storing by freezing, separating by diatomite filtration to obtain raw wine 1, subjecting filtrate to ultrafiltration membrane concentration, carrying out cold storage, and distilling to obtain raw wine 2; blending well the raw wine 1 an the raw wine 2, filtering with a 0.5 pm micro membrane, heating to 120-130 DEG C for 2-3 seconds, and sterilizing to obtain the finished wine. The method is simple and low in cost; the red dates wine produced herein hasthe sweet taste of red dates, strong fruit aroma, unique flavor and the like.

Description

technical field [0001] The invention relates to a fermented wine making method, in particular to a fermented red date wine making method. Background technique [0002] As we all know, jujube has been listed as a top-grade fruit for health and fitness since ancient times. Its nutritional value is higher than other fruits. It is rich in protein and vitamins, especially vitamin C. Therefore, it has special effects of nourishing the spleen and stomach, nourishing blood and calming the nerves, and nourishing the body. . [0003] Generally, beverage wines with specific effects are made by using the principle of similar compatibility, using ethanol and water as solvents to extract some active ingredients in animals and plants. The production process is simple and the cost is low, but the extraction effect is not ideal. Utilization rate is low, and the mouthfeel of wine, local flavor are relatively poor, are difficult to be accepted by consumer. The preparation process of fruit wi...
