Abstract
The present invention relates to a method for increasing content of gamma-amino butyric acid in tea. Fresh leaves of tea are immersed in water solution which contains 0.2 to 1.6%(weight percentage) of sodium glutamate for 1 to 6 hours. The leaves are taken out of the water solution to be put in air for 1 to 2 hours. According to the operation, after 2 to 3 times, the leaves of tea are dewatered and are processed in a common green tea technology. The content of gamma-amino butyric acid in tea produced according to the method can reach 3.5-6 mg/g. Compared with the content of gamma-amino butyric acid in tea processed in an anaerobic processing method, the content of the gamma-amino butyric acid is 20 to 80% higher. The producing cost per kilo of tea is saved by 3 to 4 yuan. The fragrance and the mouth feel are very good. When a person drinks the tea which is produced according to the method, and contains rich gamma-amino butyric acid, the purpose that blood pressure is lowered can be obtained.
Description
Technical field: the invention belongs to the processing of farm products field.
Background technology: GABA is a kind of nonprotein amino acid that contains in the minority plant, it have anticonvulsion, suppress nervous excitation, releive blood vessel and hypotensive pharmacological function.Alpha-aminobutyric acid content is very low in the tealeaves of producing with the common process method, only be about 0.1mg/g, but be rich in glutamic acid in the tealeaves, and glutamic acid is converted into GABA under the effect of glutamate decarboxylase.In the ordinary course of things, the glutamate decarboxylase activity is extremely low, the GABA that generates also just seldom, have only and adopt special technological means to handle the bright leaf of tea, just can activate the activity of this kind of enzyme, make that alpha-aminobutyric acid content increases greatly in the tealeaves, drink this tealeaves and can reach hypotensive purpose.
The method for transformation of studying GABA in the tealeaves at present both at home and abroad mainly is to dislike gas (filling nitrogen) facture, because glutamate decarboxylase activity under the condition of disliking gas strengthens greatly, the bright leaf of tea is placed under the condition of disliking gas repeated treatments a few hours, alpha-aminobutyric acid content just can rise rapidly in the tealeaves, but the equipment that the anaerobic treatment method needs is many, the operation more complicated, the energy, the labour that consume are many, the production cost height, and the tealeaves peculiar smell of producing with this method is heavier, be difficult to be accepted by the consumer, produce market is greatly affected.
Summary of the invention: the method that the object of the present invention is to provide alpha-aminobutyric acid content in the increase tealeaves a kind of easy and simple to handle, with low cost.
Technical scheme of the present invention is: the bright leaf of tea was soaked in the aqueous solution that contains 0.2-1.6% (percentage by weight) sodium glutamate 1-6 hour, taking-up placed air 1-2 hour, so operation is 2-3 time, and the dehydration back promptly obtains high gamma-aminobutyric acid tea with common green tea processes.
Principle of the present invention is: the oxygen free condition in the water substitutes the oxygen free condition that routine is filled nitrogen, adding sodium glutamate simultaneously in water makes the bright leaf of tea absorb certain external source glutamic acid when handling, thereby make glutamate decarboxylase have more reaction substrate can supply catalysis, alpha-aminobutyric acid content is higher in the tealeaves of making.
The invention has the advantages that: the anaerobic condition that it is created is very simple, easy to operate, and the equipment of input is few, the energy, the labour that consume are also less relatively, and production cost is low, and the tea aroma of producing with this method is very normal, do not have any peculiar smell, meet consumer taste.Alpha-aminobutyric acid content can reach 3.5-6mg/g in the tealeaves.Drink the tea of this method processing, can reach hypotensive purpose.
The specific embodiment:
In the pond, prepare 1 ton of the monosodium glutamate solution of 1% (percentage by weight), 100 kilograms of fresh tea passes were soaked in this pond aqueous solution 2 hours, take out and be placed in the air 1 hour.Dehydration promptly obtains high gamma-aminobutyric acid tea with common green tea processes after repeating 2 times again by aforesaid operations.Alpha-aminobutyric acid content reaches 3.5-6mg/g in the tealeaves that processes with this invention, and than with disliking the 20-80% that exceeds that gas (filling nitrogen) facture processes, production cost per kilogram tealeaves is saved 3-4 unit.Fragrance and mouthfeel are all good than anaerobic treatment method.
Claims (1)
1, a kind of method that increases alpha-aminobutyric acid content in the tealeaves, it is characterized in that, the bright leaf of tea was soaked in the aqueous solution that percentage by weight is the 0.2-1.6% sodium glutamate 1-6 hour, take out again and placed air 1-2 hour, so operation is 2-3 time, and dehydration is back with common green tea processes again.
