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, made into γ-aminobutyric acid content of not less than 1.5mg g -1 GABA tea, the product combines the physiological functions of tea itself and GABA, and has a synergistic effect, but due to the obvious sour and bad smell of the product, the market promotion is greatly restricted

Embodiment Construction

[0017] The use concentration is 80mg L -1 -150mgL -1 Glutamic acid nutrient solution, sprayed on the back of the tea tree leaf canopy that germinated from young buds after Grain Rain, and shaded with a single-layer ordinary sunshade net, sprayed the nutrient solution and shaded 7-10 days after one bud and one leaf Standard picking, the resulting fresh leaves are raw materials for making GABA tea.

[0018] Soak the fresh leaves in a mixed solution containing 3%-5% edible sucrose and 2%-3% edible sodium glutamate for 3 hours-5 hours, keep the soaking temperature at 22°C±5°C, the fresh leaves after soaking Rinse the leaves with clean tap water 3 times, centrifuge and dehydrate them with a shaker at a speed of 30-60rpm, and finish them in gradient hot water (that is, 100°C boiling water for 50 seconds, 90°C hot water for 30 seconds, and 80°C hot water for 30 seconds). second) after making GABA tea by conventional green tea processing method. The γ-aminobutyric acid content of t...

Abstract

The invention discloses a method for preparing amino butyric acid tea and the product, belonging to the technical field of tea processing. After the Grain Rain, tea is picked 7 to 10 days after being spayed nutrient solution of glutamate of 80mg L<-1> to 150mg L <-1> and shaded, then fresh tea leaves are put into a mixed solution of 3 percent to 5 percent of edible sugar and 2 percent to 3 percent of edible sodium glutamate for 3 to 5 hours, the soaking temperature is kept within 22 DEGC plus or minus 5 DEG C, the soaked fresh tea leaves are washed by tap water, centrifuge-dewatered and green-removed in hot water of gradient temperature according to normal green tea processing method, and the amino butyric acid tea is prepared. The content of gamma-amino butyric acid in the invention is more than 1.5mg g<-1>, the content of caffeine is less than 1 percent, the product has no peculiar smell of gamma-amino butyric acid tea made in Japan, the sensory index has no difference from the normal tea, the product has the effects of lowering blood pressure of gamma-amino butyric acid tea and low excitatory content of caffeine, and the market prospect of the product is wide.

Description

1. Technical field [0001] The preparation method of the GABA tea of ​​the present invention belongs to the technical field of tea processing and is used for researching and developing health food and high-efficiency and safe antihypertensive medicine. 2. Background technology [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, and γ-aminobutyric acid is enriched in tea to make the content reach 1.5mg g -1 Afterwards, it has a recognized blood pressure lowering effect. [0003] Tea i...
