The brewing method of red jujube wine with low methanol content

Abstract

The invention relates to a brewing method of low-methanol-content Chinese date wine, and belongs to the technical field of brewing. The method includes sorting Chinese dates, cleaning, stoning, soaking with hot water, pulping, adding pectin esterase and cellulase, performing enzymatic hydrolysis, stirring and cooking in an air-lift combined mechanical manner, centrifuging, separating supernatant, adjusting the supernatant with white sugar and citric acid, sterilizing, inoculating, fermenting, clarifying, filtering, adding a clarifying agent, and aging by using an oak barrel. The method degrades cell walls of fruit tissues by using the pectin esterase and the cellulase, degrades polysaccharides to allow effective components inside the Chinese dates to dissolve out, and increases the content of juice nutrients and the juice yield. Through stirring and cooking in the air-lift combined mechanical manner, methanol produced by pectin substance zymolysis through the pectin esterase and methanol produced by other reasons are separated along with stirring, cooking and high-pressure air blowing, thus reducing the methanol content in Chinese date juice pulp.

Description

Technical field

[0001] The invention relates to a method for brewing red date wine with low methanol content, and belongs to the technical field of wine making. Background technique

[0002] Jujube is a fruit with the same medicine and food. It is the largest dried fruit resource in my country. The fruit is rich in nutrition. The total sugar content in dried jujube can be as high as 60%~70%, containing Vc 340.6~601.2mg / 100g, and it also contains essential human A variety of amino acids and other nutrients. At present, jujube is mainly eaten fresh, but with the continuous improvement of jujube production and quality and the continuous emergence of new technologies in the food industry, the development of deep processing of jujube in my country is increasing rapidly, which improves the comprehensive utilization value of jujube. Among them, the use of the high sugar content of jujube to brew jujube wine has very broad development and application prospects. However, due to the produ...
