DL-Alanine is the racemic modification of alanine, which is anon-essential amino acid that occurs in high levels in its free state. DL-Alanine is acolorless to white needle crystal or crystalline powder that is odorless and has apeculiarly sweetWatch Box taste. It begins to sublime above 200ºC and the melting point is 297ºC (decomposition). It dissolves readily in water(25ºC, 17%), slightly in ethanol and insoluble in ether.

DL-Alanine is mainly used in food processing industry for nutrSocket & Outlet itional supplements and seasoning, and also used in pharmaceutical industry. DL-alanine could enhance the effect of chemical seasoning sauce. Wiith aspecial sweet taste, DL-Alanine can improve the artificial sweetEnergy Saver ener, the acidityInverter of organic acid and the flavor of vinegar.

1.It is mainly used as nutritional supplement and flavoring in food processing industry. It can also be used in the medical industry.

2.It has agood freshness and can promote the effects of chemical flavorings;

3.It has apeculiar sweetness and can improve the taste of the artificial sweeteners, improve the sourness of organic acids and the flavor of vinegar;

4.Its sourness may help salt enter vegetables, improve the quality of salted or sauce-pickled vegetables, cut short the pickling duration and improve the flavor;

5.It can be used as acorrector or buffer in the composition of wine or soft beverage, can prevent bubble wine from ageing and can decrease the odor of yeast;

6.Its function of antioxidation can be used in food processing. For instance, it can be used in oils, yolk jam, purified foods, sauce-pickled foods, and bra -pickled foods. It can both protect them from oxidation and improve their flavor;

7.It can be used as araw material for Vitamin B6 synthesis and material for the research on metabolism of amino acids by medical organisms or on abiochemical basis.

Function

DL-alanine is used as nutrition supplement and seasoning. It could improve the flavoring taste and enhance the sour of organic acid. DL-alanine could be added in pickles,kimchi,drinks and wine.
DL-aBearing lanine is raw material to manufacture VB6 and DL-alaninol,it is metabolism medication of medicine microorganism and biochemical amino acid.
