Abstract
The present 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 DEG C 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
One, technical field
The preparation method of aminobutyric acid tea of the present invention belongs to the Tea Processing technical field, is used to develop health food and highly effective and safe blood-pressure drug.
Two, background technology
Experimental study shows, GABA has that to bring high blood pressure down be main many physiological actions and the multiple physiological activities such as headstroke sequelae, calm nerve of improving, as anticonvulsion, antianxiety, recovery function of brain cell, anti-arrhythmia and adjusting hormone secretion and pharmacological function such as hypotensive.But GABA has the sour smell of tangible acid, is difficult for being accepted by people, and the alpha-aminobutyric acid content of ordinary tea leaves itself is low, and enriching gamma-aminobutyric makes content reach 1.5mg g in tealeaves
-1After have generally acknowledged blood pressure lowering effect.
Tealeaves is the specialty economies crop of China, study for a long period of time show contain a large amount of strong anti-oxidation material Polyphenols in the tealeaves, the nervous brain healthy material theanine of releiving, excited diuresis material caffeine, has biological effect widely, Tea Polyphenols is ratified to be widely used in medicine, foods and cosmetics as medicine by U.S. food Drug Administration.
In Japan, China's the island of Taiwan and continent, people utilize processing such as anaerobism (filling nitrogen or filling CO 2), dipping (immerse water in or immerse in the simple monosodium glutamate solution), microwave, infrared radiation significantly to increase alpha-aminobutyric acid content in the tealeaves, make alpha-aminobutyric acid content and are not less than 1.5mg g
-1Aminobutyric acid tea, product has the physiological function of tealeaves itself and GABA concurrently, has cooperative effect, but because product has the tangible acid bad smell of turning sour, marketing is very limited.
Angiocardiopathy is one of main illness of modern, low caffeine tea is fit to this part consumer, utilize the difference of the dissolution characteristic of other component contents of caffeine and tealeaves in hot water, behind bright leaf enriching gamma-aminobutyric, complete with gradient hot water and to remove the part caffeine, not only on producing, can save the energy, simplify technology, and can obtain the multi-functional tea products of high gamma-aminobutyric acid and low caffeine content.
Three, summary of the invention
Technical problem
The purpose of this invention is to provide a kind of method for preparing aminobutyric acid tea.Alpha-aminobutyric acid content＞1.5mg the g of the aminobutyric acid tea product that makes by this method
-1, caffeine content is lower than 1%, product does not have the unusual odor that Japan produces gamma-aminobutyric acid tea.
Technical scheme
1, the preparation method of aminobutyric acid tea is characterized in that:
(1) working concentration is 80mg L
-1-150mg L
-1The glutamic acid nutrient solution, after grain rains, spray the tea free layer of sprouting in young shoot, and shade, 7 days-10 days harvesting tealeaves with the common sunshade net of individual layer;
(2) fresh tea leaf is inserted in the edible sodium glutamate mixed solution of the edible sucrose that contains mass ratio 3%-5% and mass ratio 2%-3% and soaked 3 hours-5 hours, soaking temperature remains on 22 ℃ ± 5 ℃, fresh tea leaf after the immersion washes 3 times with running water, with the rotating speed centrifugal dehydration of vibration machine with 30-60rpm, completing in gradient hot water, (promptly 100 ℃ of boiling water completed 50 seconds, 90 ℃ of hot water completed 30 seconds, and 80 ℃ of hot water completed 30 seconds) after routinely green tea processing method make aminobutyric acid tea.
Above-mentioned concentration is 80mg L
-1-150mg L
-1The glutamic acid nutrient solution for containing glutamic acid 80mg L
-1-150mg L
-1The aqueous solution.Containing the edible sucrose of mass ratio 3%-5% and the edible sodium glutamate mixed solution of mass ratio 2%-3% is the aqueous solution that contains mass ratio 3%-5% edible sucrose and the edible sodium glutamate of mass ratio 2%-3%.
Beneficial effect
(1) aminobutyric acid tea contains the main biochemical component of tealeaves itself and higher alpha-aminobutyric acid content, lower caffeine content, and does not have the unusual odor that Japan produces gamma-aminobutyric acid tea, the invention provides the method for preparing aminobutyric acid tea.Alpha-aminobutyric acid content＞1.5mg the g of the aminobutyric acid tea that makes by this method
-1, caffeine content is lower than 1%, organoleptic quality is normal, provides the basis for developing health food and highly effective and safe blood-pressure drug.
(2) enforcement of the present invention can improve spring dust tea and the economic benefit of summer autumn tea greatly, the economic benefit main source of Chinese tea and the famous-brand and high-quality tea of producing before grain rains, usually produce common green tea or red green tea at Chun Mo and autumn tea season in summer, selling price is low, deficiency in economic performance, in many places, even do not produce the summer autumn tea, cause the waste of summer autumn tea raw material, and the aminobutyric acid tea of producing according to technology of the present invention is a Special tea, price is 2-3 a times of common tea, and economic benefit is very obvious.
(3) of the present invention being implemented in can be saved the energy, simplification technology in the production, and can obtain the multi-functional tea products of high gamma-aminobutyric acid and low caffeine content.
