Embodiment 1

[0052] A lactic acid bacterium produces a fermented liquid high in gamma-aminobutyric acid, the preparation method of which is as follows:

[0053] (1) Germinate brown rice and barley until the leaf bud length is 1 / 3 of the seed, heat to 40°C for 5 minutes, stop germination, and mix with mulberry leaves. The mass ratio of brown rice, barley and mulberry leaves is 1:2:1.5, Pulverize to get mixed powder;

[0054] (2) Soak the mixed powder in water according to the mass volume ratio of 0.25:1g / mL, heat at 55°C for 0.5h, then raise the temperature to 60°C, keep it warm for 2h, and filter while it is hot to obtain the filtrate;

[0055] (3) Add glutamic acid with a mass fraction of 0.5% to the filtrate, heat to 105°C to sterilize for 10 minutes, insert Lactobacillus plantarum, inoculate 1.0%, ferment at 35°C for 6 hours, filter, and the filtrate is produced by lactic acid bacteria Fermentation broth high in γ-aminobutyric acid.

Abstract

The invention relates to the field of fermentation technologies and cosmetics, in particular to a preparation method for producing fermentation liquor with a high [gamma]-aminobutyric acid content byemploying lactic acid bacteria, and an application of fermentation liquor in cosmetics. The preparation method comprises the following steps of: (1) enabling brown rice and barley to sprout, mixing the sprouted brown rice and barley with folium mori, and smashing the mixture to obtain a mixed powder; (2) adding water into the mixed powder for dipping, and conducting filtering to obtain a filtrate;and (3) adding glutamic acids or / and glutamate into the filtrate, inoculating fermentative bacteria, and conducting filtering to obtain the fermentation liquor. The fermentation liquor has the advantages of high [gamma]-aminobutyric acid content, good use effect and no side effects when the fermentation liquor is applied to cosmetics.

Description

technical field [0001] The invention relates to the fields of fermentation technology and cosmetics, in particular to the production of fermented liquid containing high gamma-aminobutyric acid by lactic acid bacteria and its application in cosmetics. Background technique [0002] γ-aminobutyric acid (GABA), English name: γ-aminobutyric acid, chemical name: 4-aminobutyric acid, aliases: aminobutyric acid, pipecolic acid, widely distributed in animals and plants. Seeds, rhizomes and tissue fluids of plants such as beans, ginseng, and Chinese herbal medicines all contain GABA. In animals, GABA exists almost only in nerve tissue, and the content in brain tissue is about 0.1-0.6mg / gram tissue. GABA is an important neurotransmitter with a variety of physiologically active functions. It has physiological effects on human epidermal cells, such as physiological repair, cell activation, skin rejuvenation and beauty. GABA is also closely related to the quality of sleep and is known a...
