Problems solved by technology

[0004] In Japan, my country's Taiwan Island and the mainland, people use anaerobic (nitrogen or carbon dioxide), soaking (immersion in water or in simple sodium glutamate solution), microwave, infrared irradiation and other treatments to greatly increase the γ-amino in tea. Butyric acid content, make GABA tea with γ-aminobutyric acid content not less than 1.5mgg-1, the product has both the physiological functions of tea itself and GABA, and has a synergistic effect, but because the product has obvious Sour and bad smell, marketing is greatly restricted

Abstract

The invention relates to the technical field of green tea, in particular to a preparation method of gamma-aminobutyric acid green tea. The preparation method of the gamma-aminobutyric acid green tea comprises the following steps: completely washing the freshly picked tea, putting the tea into a refrigeration storage to perform refrigeration treatment, mixing the tea with a nutrition enhancer consisting of black soybeans, giant-embryo black rice and peanuts, putting the mixture under the condition that the vacuum degree is -0.03 to -0.06 mpa to perform anaerobic treatment, and performing superfine pulverization to obtain the gamma-aminobutyric acid green tea. Transient glutamic acid cyclic inhibition is formed through low-temperature treatment, the tea and the nutrient enhancer are subjected to mixed vacuum treatment, circulation of cell glutamic acid in the tea is accelerated, the glutamic acid is completely consumed, and the aminobutyric acid content of the tea and the nutrient enhancer is increased, so that the green tea has rich nutritional substances and has more prominent health-care effect.

Description

technical field [0001] The invention relates to the technical field of green tea, in particular to a method for preparing gamma-aminobutyric acid green tea. Background technique [0002] Experimental studies have shown that γ-aminobutyric acid has many physiological effects and various physiological activities such as lowering blood pressure, improving stroke sequelae, calming nerves, etc., such as anticonvulsant, anti-anxiety, restoring brain cell function, anti-arrhythmia and regulating hormones Pharmacological functions such as secretion and hypotension. However, γ-aminobutyric acid has an obvious sour smell, which is not easy to be accepted by people. The content of γ-aminobutyric acid in ordinary tea itself is low. After enriching γ-aminobutyric acid in tea to make the content reach 1.5mgg-1, it has Recognized blood pressure lowering effect. [0003] Tea is a characteristic economic crop in my country. Long-term studies have shown that tea contains a large amount of p...
