Application:
L-Aspartic Acid Sodium Salt Monohydrate (CAS: 323194-76-9) has excellent fresh-showing and preservative effect, widely used in food industry as fresh-showing agent and preservative, can replace monosodium glutamate. It is often used with natural seasoning, sodium glutamate, glycine or sodium citrate, sodium succinate, etc. Mainly used in all kinds of curry, vinegar, canned fish, canned vegetables, bread, biscuits, drinks and so on as flavor improver. If used in orange juice and other refreshing drinks, because of a unique refreshing fragrance. (1) Adding orange juice and other cool drinks can increase the cool feeling because of its unique refreshing flavor; (2) Combined with other condiments, it can increase efficiency to make strong flavor; (3) It can remove bitterness when used with saccharin sodium; (4) Adding soda, Coca Cola and other carbonated drinks can increase the retention of carbon dioxide; (5) Added to aquatic products, it can make the flavor stronger. In addition, it has the function of inhibiting the change of food color and flavor. Food Grade 1. Freshener and preservative Has excellent freshness and antiseptic effects. It is widely used as freshener and preservative in food industry and can replace monosodium glutamate 2.
