Application:

L-Lysine L-Aspartate (L-Lys L-Asp) (CAS: 27348-32-9) is used as food and feed additives; nutrition fortifiers; nutrition supplements.
1. Amino acid enhancer. Lysine is an essential amino acid in human body, which can enhance hematopoietic function, enhance gastric juice secretion, improve protein utilization, maintain metabolic balance, increase disease resistance, and promote the development of children's physique and intelligence.
2. Nutritional supplements (mainly as L-Lysine enhancers). Because the odor is smaller than L-Lysine, it has little effect on the flavor. It is used as accessory substance and has a good effect. It can also be used as a seasoning for refreshing drinks, bread and starch products.
3. Mainly used as a nutritional fortifier in food
27348-32-9 - Preparation Method: Obtained by neutralization of free L-lysine with equimolar L-aspartic acid, concentration, crystallization and separation.
