Applications: L-Lysine is mainly used as food intensifier and pharmacy.
1)Foodstuff industry: L-Lysine is one of the eight essential amino acids that can not be synthesized by human body and lack in daily food supply. Therefore, it is called "The 1st essential amino acid."To add L-lysine into rice, flour, canned food can improve protein utilization rate, thus, to greatly enrich food nutrition, promote growth and maturity, increase appetite, reduce diseases, and invigorate health. In canned food, L-Lysine can function as deodorant and preservation.
2) Pharmaceutical industry: L-Lysine can be used to formulate compound amino acid infusion preparations. Together with various vitamins and glucose, L-Lysine can be prepared to nutrition supplement. It will be easier to be absorbed in stomach and intestine. L-Lysine can also improve properties of some medicines and raise drug efficacy. [Storage]: Keep in dry, clean, shading place. Sealed in containers.
[Packing]: Packed in craft paper bags or paperboard barrels of 25KG each, or customized. [Transportation]: Handle with care, protect from sunlight, rains and damage on packaging. L-Lysine is non-hazardous, keep it away from poisonous and harmful substance in transit. [Storage]: Store in cool and dry place.
