Abstract

The invention provides a method for preparing grape wine rich in gamma-aminobutyric acid. The invention belongs to the technical field of wine brewing, which in particular relates to a method for preparing health-care grape wine. On the basis of the traditional brewing technique of claret, an MRS culture medium, saccharification liquid and yeast slurry are utilized to culture and obtain lactobacillus brevis. Then, a lactobacillus brevis yeast starter obtained by centrifugation and freeze drying and active alcoholic wine cocci are added into the apple emulsion fermentation stage of the claret together. Gamma-aminobutyric acid fermentation 2d is carried out, malic acid-lactic acid fermentation 5d is carried out below 20 DEG C, and the gamma-aminobutyric acid fermentation 2d and the malic acid-lactic acid fermentation 5d are both carried out under a closed condition. The content of the gamma-aminobutyric acid of a finished product of the grape wine is 1g / L (the content of the gamma-aminobutyric acid in the existing finished product wine is 0.05-0.1g / L), the vinosity is delicate and mellow, the fragrance is elegant and noble, and the finished product of the grape wine is in a clear ruby-red color.

Description

Technical field: [0001] The invention belongs to the technical field of wine making, in particular to a method for making health-care wine. Background technique: [0002] As a non-protein amino acid, γ-aminobutyric acid has the functions of lowering blood pressure, promoting sleep, relieving anxiety, improving the oxygen supply to the brain, etc. It has high physiological activity, and a small amount of intake is very beneficial to human health. [0003] The application of γ-aminobutyric acid in functional foods has increasingly become a focus of attention. As early as the mid-1980s, the Japanese tea drink Gabaron was a representative product rich in γ-aminobutyric acid. In 1996, Japan successfully developed rice germ products rich in γ-aminobutyric acid (GABA). In recent years, , Japanese scientists use rice germ and other raw materials to develop and manufacture a series of health food ingredients rich in GABA, which are widely used in beverages, jams, pastries, biscuits,...
