Microbial fermentation l-theanine

Key Attributes.

The functions of L-Theanine Excellent flavor improving effect, antidepressant, effective in improving sleep quality, relaxation sedation Anti-anxiety, but does not cause drowsiness, lowering blood pressure functions, the promotion of learning and memory function of the brain, enhance immunity, anti-fatigue, enhance the efficacy of anticancer drugs The Securities of L-Theanine As early as 1985, the U.S. Food and Drug Administration on the approval of theanine and confirmed that theanine is a generally recognized as safe substances, not do in the course of limited use provisions. The uses of L-theanine 1. L-Theanine can be used in tranquilizer sedative drugs. 2. L-Theanine can be used as the quality of tea improver. 3. L-Theanine can be used as additives to improve food flavor. 4. L-Theanine can be used as functional food additives. 5. L-Theanine can be used as anticancer drugs. 6. L-Theanine can be used in lower blood pressure drugs. The comparision of L-theanine through the process enzyme synthesis with through the process of chemical synthesis 1. L-Theanine through the process of microbe ferment is all L type,because of special and distinctive effect of microbe enzyme.Specific Rotation ???20/D of our product is +8.2-+8.3degree 2. During the process of microbe ferment,we do not add any chemistry reagent .The raw material of production are L-Glutamine and ethylamine.so do not worry about the safety of our product. 3. All the raw materials of our product are food grade. Technological process of L-Theanine 1. Preparation of L-theanine synthesie enzyme (enzyme Gamama-glutamyltranspeptidase) 2. Inoculation? Yeast Ferment ? Centrifugal ? Cell division 3. The synthesis of L-theanine by enzyme 4. L-glutamine + ethylamine ? add enzymegamama-glutamyltranspeptidase Then reaction?Inactivation of enzyme gamama at 80?,retrieve ethylamine?Filtrate and remove yeast fungusprotein?Treat with active carbon?Concentration?Dry
