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 [α] 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.
