Embodiment 1

[0019] Embodiment 1: a kind of preparation method of the mulberry leaf tea that is rich in GABA, it comprises the following steps:

[0020] S1. Withering: put the fresh mulberry leaves in a shading place and spread them thinly, and wither until the water content of the mulberry leaves is 60%; the temperature of the withering is 15°C, and the withering time is 8 hours; the thickness of the thin spreads is 2-3cm;

[0021] S2. GABA-enrichment treatment: Spray the withered mulberry leaves with a mixed solution of glutamic acid and sodium glutamate, after spraying, shading treatment for 3 hours, then fill with carbon dioxide at room temperature for 1 hour, and then treat in an aerobic environment for 1 hour , and finally filled with carbon dioxide sealing treatment for 1h; the weight ratio of the mulberry leaves to the mixed solution is 1:5, the weight ratio of glutamic acid and sodium glutamate in the mixed solution is 1:1, and the mass of the mixed solution The percentage concent...

Abstract

The invention discloses a preparation method of mulberry leaf tea containing rich GABA (gamma-aminobutyric acid). According to the preparation method, mulberry leaves and tartary buckwheat are used as raw materials, and health-care mulberry leaf granulated tea with the functions of calming the nerves, lowering blood lipid and lowering blood pressure is prepared through withering, carrying out GABA enriching treatment, drying, crushing, carrying out formula granulation, frying and sieving. The GABA is an important inhibitive nerve transmitter substance and has extremely high biological activity; the content of the GABA in the mulberry leaves is improved through adopting exogenous glutamic acid, sodium glutamate and anaerobic-aerobic alternation, and the tartary buckwheat is also added, so that the content of the GABA in the processed mulberry leaf tea is high and can reach 1.53mg/g; the grass flavor of original mulberry leaves is improved, and the taste is improved; and the preparation method is simple to operate, convenient in preparation and low in cost and is suitable for industrial large-scale production.

Description

technical field [0001] The invention relates to a method for preparing tea, in particular to a method for preparing mulberry leaf tea rich in GABA. Background technique [0002] For a long time, mulberry leaves have been used as the main feed for silkworms. However, with the deepening of the research on mulberry leaves, the nutritional value and medicinal value of mulberry leaves have attracted more and more people's attention. Mulberry leaves not only contain a large amount of protein, fat, carbohydrates, vitamins and mineral components that people need. It also contains polysaccharides, polyphenols, 1-deoxynominmycin (DNJ), and γ-aminobutyric acid (GABA). Modern research proves that mulberry leaves can lower blood sugar, blood pressure, and blood lipids, increase the activity of superoxide dismutase in the body, and have tonic and anti-aging effects similar to ginseng. [0003] The content of protein in mulberry leaves is 15%-30% of dry basis weight, which is a plant wit...
