Uses and synthesis of Aspartic acid powder

Aspartic acid powder is a widespread acidic amino acid. The content in tea leaves is relatively constant. White monoclinic column crystal, Aspartic acid CAS 6899-03-2, slightly soluble in water, with acidic fresh taste, melting point 278 ℃.

Young buds and leaves in the content of 0.05% to 0.25%, alpine tea up to 0.4% to 0.5%; with the aging of the leaves and decreasing, but the annual growth period, any season are more content, Aspartic acid Raw Materials in the amino acid library of the important role of the same role as glutamic acid. The important role of Aspartic acid Raw Materials in the amino acid pool is the same as that of glutamic acid.

Applications / Functions of Aspartic acid powder

1. Aspartic acid CAS 6899-03-2 is used as a food additive, used as a flavouring agent for beverages, ice cream, etc. It is also used as a food additive, as a flavouring agent for beverages, ice cream, etc;
2. Aspartic acid powder Used as pharmaceuticals, used for liver function promoter, fatigue recovery agent, amino acid infusion agent, etc., can be used alone, or with other drugs;
3. Used as biochemical reagent and culture medium; Aspartic acid Raw Materials is also used as organic synthesis intermediates; synthetic aspartic sweet mother; cosmetic additives and so on.

Physicochemical Property of Aspartic acid powder

Aspartic acid Raw Materials is α-aminosuccinic acid, symbol Asp, an aliphatic acidic amino acid with a dicarboxylic group. It is the basic component of protein. Chemical formula C4H7NO4, molecular weight 133.10, structural formula HOOC-CH2CH(NH2)COOH.

Isoelectric point approximation 2.77, insoluble in water, solubility 0.05% in water at 25 ℃, flavour and acidity, threshold value of 0.15%. Melting point 270 ℃, Aspartic acid powder widely distributed in the tea tree tissues and sap

Production methodprocess of Aspartic acid powder

• ①Hydrolysis of aspartic acid.
• ②Take fumaric acid and ammonia as raw materials, and synthesise them under the action of aspartic enzyme, then D-body can be produced. Recently, Japan has developed the synthesis of aspartic acid with polysaccharide κ-carrageenan instead of asparaginase, which can improve the yield.
• (iii) Fermentation is carried out using glucose as raw material. Fermentation can be carried out by free bacterial method and fixed bacterial method.
• (iv) De-hydrolyse the protein of aspartic acid with acid or base.
