Why choose plant enrichment method to prepare gamma-aminobutyric acid?

Gamma-aminobutyric acid is a kind of can be widely used in coffee, tea, candy, baked goods, snack food, chocolate, cocoa products such as amino acid, although has the very high food safety, but are not allowed to used for baby food, meat products, such as when using need to control the dosage of the gamma-aminobutyric acid, as a general rule, be within 500 mg/d.

Through plant enrichment method, chemical synthesis method, microbial fermentation method and other methods, we can obtain γ -aminobutyric acid, preparation methods, but each has advantages and disadvantages. Plant enrichment method has low production cost and high purity. The raw materials used in chemical synthesis are easy to obtain, but the reaction is difficult to control, and the cost is high. It is difficult to achieve large-scale production due to the high requirements of environment and equipment in the preparation process.

Therefore, in the above several preparation methods, plant enrichment method is undoubtedly more suitable for the preparation of γ -aminobutyric acid method. Enrichment method, then, we’ll learn about plants, it can be divided into column separation, preparation method and solvent extraction, column preparation method is also called the separation of column chromatography, it USES different components in the solid liquid two phase mixture composition distribution coefficient for different elution, separation, such as operation, often will resin, activated carbon or silica as filler material use of chromatographic column, And solvent extraction method in the extraction agent is mainly water or alcohol, using plants in water or alcohol will produce different solubility and distribution coefficient to extract γ -aminobutyric acid, after repeated filtration and purification, can extract most of the plant γ -aminobutyric acid.
