Problems solved by technology

It solves the problem that banana peels are discarded as garbage and causes environmental pollution. In addition, a lot of broken tea is produced in black tea processing, which is not suitable for drinking. At present, it is generally used as fertilizer, and the added value is not high. The invention uses the broken tea produced in black tea processing to ferment and prepare Fruit wine, can increase the added value of this scrap

Embodiment 1

[0034] The preparation method of the banana extract is as follows: take a certain amount of banana peel and crush it, add deionized water according to the ratio of the fresh weight of the banana peel to the water weight volume ratio of 1:2, extract at room temperature for 2 hours, centrifuge to get the supernatant, Get banana peel extract. Define the amount of enzyme required to catalyze the decarboxylation of glutamic acid to produce 1umol of GABA per minute as one enzyme activity unit, and the enzyme activity of supernatant GAD is 1.8U / mL;

[0035] Take 50 grams of crushed red tea powder, add 2000ml of deionized water, and extract in a boiling water bath for 10 minutes. After cooling, add 1500ml of banana peel extract, adjust the pH to 5.5-6.0, enrich for 0.5h under stirring, and the GABA content in the solution reaches 0.39mg / mL; saccharomyces yeast with a mass volume ratio of 10%, fermented for 2 days at 30°C and a shaker speed of 160rpm, and centrifuged to obtain black t...

Abstract

The invention discloses a preparation method of a gamma-aminobutyric acid black tea wine. The preparation method comprises the following steps of (1) smashing; (2) leaching: leaching tea powder in a boiling water bath, and cooling for later use; (3) GABA (Gamma-Aminobutyric Acid) enrichment: a, smashing banana peels, adding deionized water, leaching at room temperature, and centrifuging to obtain a banana extracting solution; b: cooling the (2), then, adding the banana extracting solution, adjusting the pH value, and enriching the GABA; and (4) fermentation: after the leaching operation is ended, filtering to obtain a tea soup, adding a yeast and saccharose, fermenting and centrifuging to obtain the black tea wine. The method disclosed by the invention is simple and short in preparation period; the GABA is enriched by taking Glu in the broken black tea as the raw material by means of the activity of GAD (Glutamic Acid Decarboxylase) in bananas, so that the product red wine has the health care function of the GABA; the nutritional ingredients in the banana extracting solution are utilized by the yeast in the fermentation process, so that resources are greatly utilized; and the product has the composite fragrance of black tea, bananas and wine and is a soft and refreshing high-quality tea wine.

Description

technical field [0001] The invention belongs to the technical field of food processing, and relates to gamma-aminobutyric acid black tea fruit wine and a preparation method thereof. Background technique [0002] γ-aminobutyric acid is a non-protein functional amino acid that widely exists in nature and is an important inhibitory neurotransmitter in the central nervous system of mammals. It has important body functions, such as regulating blood pressure and heart rate, nutrition Nerve cells, promote mental stability, promote brain blood flow, enhance brain vitality and other functions. The GABA content in natural food materials is mainly increased through enrichment methods, using exogenous sources of Glu or using the Glu contained in the food itself, Activate the GAD enzyme contained in itself for enrichment. At present, brown rice and tea are mainly used for enrichment. Due to the limited Glu in the raw material, the simple use of the Glu in the raw material itself has limi...
