Applications:
♔ Food Fortifier: L-Threonine is an important nutritional fortifier that can fortify cereals, pastries, and dairy products. Like tryptophan, it can relieve human fatigue and promote growth and development.

♔ Pharmaceutical: Because the structure of threonine contains hydroxyl groups, it has a water-holding effect on human skin. It combines with oligosaccharide chains and plays an important role in protecting cell membranes. It can promote phospholipid synthesis and fatty acid oxidation in the body. Its preparation has medicinal effects of promoting human development and fighting fatty liver, and is an ingredient in the compound amino acid infusion. At the same time, threonine is also a raw material for manufacturing a type of highly efficient and hypoallergenic antibiotics - monomycins.

♔ Feed: As an amino acid for feed, threonine is widely used in piglet feed, breeding pig feed, broiler feed, shrimp feed, eel feed, etc. Threonine is the second limiting amino acid in pig feed and the third limiting amino acid in poultry feed.
