Embodiment 1

[0034] Select 10kg of mature South Jerusalem artichoke No. 9 Jerusalem artichoke, remove the defective fruit, remove impurities, wash with water, crush and beat; dilute the Jerusalem artichoke slurry with water at a ratio of 1:1, then heat to 80°C, stir evenly and keep it for 85 minutes; while it is hot Add 1200g (100g / L) of sucrose to the slurry, stir evenly to dissolve it completely. Cool the Jerusalem artichoke slurry to 30°C, add 1.2g of potassium metabisulfite (SO 2Content 50mg / L), compound pectinase 0.36g (30mg / L, compound pectinase is pectinase EX), stand still for 24 hours for clarification and enzymolysis; .1977 and Saccharomyces cerevisiae DV10 mixed yeast 6g (the mass ratio of the two bacteria is 1:2, 500mg / L), stirred and mixed, and the fermentation was successfully triggered after 60h; finally, the temperature was slowly lowered to 18°C ​​for low-temperature fermentation. Wherein, after adding potassium metabisulfite, carry out a closed pouring, after adding yeas...

Embodiment 2

[0054] Choose 30kg of mature South Jerusalem artichoke No. 9 Jerusalem artichoke, remove defective fruit, remove impurities, wash with water, crush and beat. Dilute the Jerusalem artichoke slurry with water at a ratio of 1:1.5, then heat to 90°C, stir evenly and keep for 95min. Add 5850g (130g / L) of sucrose to the slurry while it is hot, and stir evenly to dissolve it completely. Cool the Jerusalem artichoke slurry to 35°C, add 5.4g of potassium metabisulfite (SO 2 Content 60mg / L), compound pectinase 2.25g (50mg / L, compound pectinase is pectinase EX), stand still for 12h for clarification and enzymolysis; then cool down to 28°C, add Kluyveromyces marxense CGMCC2 .1977 and Saccharomyces cerevisiae DV10 mixed yeast 31.5g (the mass ratio of the two bacteria is 1:3), stirred and mixed, and the fermentation was successfully triggered after 50 hours; finally, the temperature was slowly lowered to 22°C for low-temperature fermentation. Wherein, after adding potassium metabisulfite,...

Abstract

The invention discloses a brewing method of low-alcohol Jerusalem artichoke health-care wine. The brewing method comprises the steps of raw material selection and processing, strain selection, ethanol fermentation, ageing, clarification, stabilization and the like. According to the method, optimized southern Jerusalem artichoke No.9 is used as a raw material; before fermentation, pulping, dilution, heating, cane sugar adding and the like are conducted on the Jerusalem artichoke; saccharomycetes of kluyveromyces marxianus yeast CGMCC2.1977 and saccharomyces cerevisiae DV10 are selected to perform high-temperature enzymolysis, high-temperature start and low-temperature long-time fermentation so as to convert cane sugar and reducing sugar into ethanol and degrade high polymeric fructose degradation into low polymeric fructose; maturing of a wine body is speeded up and the quality of the wine body is improved by utilizing low-temperature ageing; the Jerusalem artichoke wine is kept in a clarified and stable state for a long time through natural clarification, heat treatment, cold treatment, filtration, microfiltration and other combination technologies. By means of the process, the high-quality low-alcohol Jerusalem artichoke wine integrating excellent color, aroma and taste and having a certain health-care function can be obtained.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a brewing method of low-alcohol Jerusalem artichoke wine. Background technique [0002] Jerusalem artichoke, also known as Jerusalem artichoke, five-star grass, and ghost ginger, is a perennial herbaceous plant of the family Asteraceae and the genus Sunflower. Native to North America, it was introduced to Europe in the 17th century and then to China. Jerusalem artichoke itself has the characteristics of cold and drought tolerance, wind and sand resistance, and strong reproductive ability. It is an ideal plant for wind and sand fixation, water and soil conservation, and improvement of saline-alkali land. Jerusalem artichoke has high nutritional value, and its underground tubers can be eaten or used as raw materials for starch and alcohol production. It is not only an important raw material for industry and food, but also can be used as animal forage. It is called "a cro...
