Description

DL-Alanine is the racemic modification of alanine, which si a non-essential amino acid that occurs in high levels in its free state in plasma. DL-Alanine is a colorless to white needle crystal or crystalline powder that is odorless and has a peculiarly sweet taste. It begins to sublime above 200℃ and the melting point is 297℃ (decomposition). It dissolves readily in water(25℃, 17%), slightly in ethanol and insoluble in ether. DL-Alanine is mainly used in food processing industry for nutritional supplements and seasoning, and also used in pharmaceutical industry. DL-alanine could enhance the effect of chemical seasoning sauce. Wiith a special sweet taste, DL-Alanine can improve the artificial sweetener, the acidity of organic acid and the flavor of vinegar. With sour, DL-Alanine could make salt fast tasty, to improve the effect of pickled vegetables and pichles. It could shorten the curing time and improve the flavor. As sour correction agent and buffer in synthesis of wine and drink, DL-Alanine could prevent foaming wine aging and reduce the smell of yeast. With antioxidant properties, DL-Alanine could be used in a vatiety of food processing, such as oil, egg yolk sauce, grains, soy sauce dipping food, rice bran preservend food.
