Uses 1.Threonine is a feed nutrient enhancer, being the essential amino acids for the growth of livestock and poultry fish. It is mainly added to wheat, barley and other cereal-based feed.
2. For biochemical research.
3. It can be used as nutritional supplements. Requirement amount (mg/k/D): 60 to 87 for children, 310 to 560 for adults with great variance and is still affected by total protein in food and amino acids.
4. The first limiting amino acid for rice, wheat, bread, corn, etc. is glycine, which may be supplemented with a secondary restricted amino acid, threonine. It can still strengthen the peanut powder, oats and so on.
5. In order to exert the best efficacy, it can be co-used with glycine in rice, and co-used in wheat flour together with glycine and valine, and co-used with glycine and methionine in barley, oats, and co-used with glycine and tryptophan in corn.
6. It is easy to produce coke aroma and chocolate aroma upon co-heating with glucose. It has aromatherapy role.
