L-Aspartic acid Powder Usage and Synthesis.

L-Aspartic acid has a wide range of uses in medicine, food and chemical industry. In medicine, it can be used in the treatment of heart disease, liver disease, hypertension, has the effect of preventing and recovering fatigue, and together with a variety of amino acids, it is made into amino acid infusion, which is used as ammonia detoxifier, liver function promoter and fatigue recovery agent.

Uses of L-Aspartic acid.

Used as electrolyte supplement for amino acid infusion, inorganic ion supplements such as potassium and calcium, and fatigue recovery agent.

Potassium and magnesium aspartate injection or oral solution is used for cardiac arrhythmia and premature beats caused by cardiac glycoside poisoning, tachycardia, hypokalemia, hypomagnesium, heart failure, myocardial infarction, angina pectoris, hepatitis, cirrhosis and other disorders.

Low toxicity, the product is not diluted for injection, renal insufficiency and atrioventricular block with caution.

It can be used as ammonia detoxifier, liver function promoter, fatigue recovery agent and other medicines, food additives and additives for various cool drinks, also can be used as biochemical reagents, culture medium and intermediates for organic synthesis.

It can be used as synthetic sweetener, used in the treatment of heart disease, used as liver function promoter, ammonia detoxifier, fatigue eliminator and component of amino acid infusion.

Nutritional supplements, flavouring and aroma enhancers. It is added to various kinds of refreshing beverages. Used as ammonia detoxifier, liver function promoter, fatigue recovery agent.

Characteristic of L-Aspartic acid.

White crystal or crystalline powder, slightly acidic taste. Soluble in boiling water, slightly soluble in water at 25℃(0.5%), easily soluble in dilute acid and sodium hydroxide solution, insoluble in ethanol, ether, heated to 270℃ decomposition, isoelectric point 2.77, its specific rotation is related to the solvent dissolved. In acid solution it is right-spin, in alkali solution it is left-spin, and in aqueous solution it is right-spin. [α]25D+5.05 (C=0.5-2.0g/ml,H2O).

Production Method of L-Aspartic acid.

L-aspartic acid is prepared by synthetic and fermentation methods.

1. The synthetic method is mainly based on maleic acid or fumaric acid or their esters, which are treated with ammonia under pressure and then hydrolysed. It is easier to synthesise to obtain racemic aspartic acid, but so far there is no ideal method for splitting the racemate.

2. Fermentation method under the action of enzyme, fumaric acid and ammonia addition, can be obtained in high yield products. With this method only levulose body is produced with high yield, so it is the main method for industrial production.
