DL-Alanine (H-DL-Ala-OH; DL-Ala) (CAS: 302-72-7) Function:
1. Medicine
(1) DL-Alanine is an important raw material for the synthesis of VB6, nutrients is one of the components of the filling pure amino acids nutrition infusion.
(2) DL-Alanine as the main component of the amino acid injection - 800, the attending liver, brain, and help patients with hepatic coma wake up quickly, is also a kind of diuresis medicine.
(3) DL-alanine is also an important intermediate for the synthesis of some pesticides and medicines, medical microorganisms and biochemical amino acid metabolism drugs.
2. Food additives
(1) DL-Alanine can improve the nutritional value of food, in all kinds of food and beverages, such as: bread, water ice point, fruit tea, milk, soda, sorbet, and so on.Add 0.1~1% of alanine can obviously improve the utilization rate of the protein in food and beverage, and because the alanine has the characteristics of can be absorbed by the cells directly, therefore, after drinking can quickly restore fatigue, refreshing.
(2) Artificial sweeteners to improve the sense of taste, can make the sweetness efficiency, reduce the dosage.In compound with sweet mei agent of 1~10% of alanine, can improve the sweetness, sweet, soft as natural sweet mei agent, and can improve the taste.
(3) DL-Alanine has special sweetness, It is mainly used as nutrient supplement and seasoning in food processing industry. Used as a flavoring agent.Can add spice seasoning effect;Correction also can be used as sour agent, improve the sour taste of organic acid.
(4) With sour taste, make salt taste fast, improve the effect of pickles, pickles, can shorten the pickling time, improve the flavor; As an acid correction agent and buffer for synthetic sake and refreshing drinks, it can prevent the aging of sparkling wine and reduce the yeast odor. It can be used in all kinds of food processing, such as oil, mayonnaise, coarse food, soy sauce impregnation food, rice bran pickled food, etc. It can not only prevent oxidation, but also improve its flavor.
(5) DL-alanine is used as nutrition supplement and seasoning. It could improve the flavoring taste, enhance the sour of organic acid. And dl-alanine could be used in pickles, drinks and wine.
