L-Threonine

DL-Threonine is an essential amino acid that plays a crucial role in protein synthesis and is an important component of animal feed and food additives. As a chemical and food-grade product, DL-Threonine is widely used in the production of poultry, pig, and cattle feed, as well as in the food and beverage industry.
Chemical Properties
DL-Threonine is an alpha-amino acid that has a hydroxyl group attached to the beta carbon atom. It is soluble in water and slightly soluble in ethanol. The chemical formula for DL-Threonine is C4H9NO3, and its molecular weight is 119.12 g/mol.
Manufacturing Process
DL-Threonine is commercially produced through microbial fermentation. In this process, bacteria such as Escherichia coli or Corynebacterium glutamicum are grown in a nutrient-rich medium containing glucose or molasses. These bacteria then produce DL-Threonine through a series of enzymatic reactions.
Food and Feed Applications
DL-Threonine is commonly used as an animal feed additive to improve the nutritional value of feed and promote animal growth. It is particularly important in poultry and pig diets as these animals cannot synthesize threonine themselves.
In the food and beverage industry, DL-Threonine is used as a flavor enhancer and as a source of amino acids in dietary supplements. It is also used in the production of infant formulas to ensure that they provide a complete and balanced source of nutrients.
Quality Control
DL-Threonine used in animal feed and food products must meet strict quality control standards to ensure its safety and effectiveness. The product is tested for purity, potency, and absence of harmful contaminants such as heavy metals, pathogens, and pesticides.
Conclusion
As an essential amino acid, DL-Threonine is a critical component of animal feed and food additives. Its importance in promoting animal growth and development and improving the nutritional value of food cannot be overstated. As a chemical and food-grade product, DL-Threonine undergoes strict quality control to ensure its safety and effectiveness in animal feed and food products.
