Among the eight essential amino acids required by humans and animals, threonine is the fourth amino acid after methionine, lysine and tryptophan. Threonine plays an increasingly important role in human growth and development, and is widely used in the food industry, feed industry and medical treatment.
Due to the high degree of food processing, large production volume, long shelf life and wide circulation, nutrients are easily damaged and lost and need to be supplemented. Therefore, the importance of food fortification in the food industry is becoming more and more prominent, and amino acid fortification agents occupy an important position in the production of food fortification agents. Threonine protein and glucose cohesion can produce a burnt flavor and have a flavor enhancing effect. It is generally used in combination with other amino acids to fortify cereals, and sometimes also used in cakes, baby food and milk to act as an antioxidant.
Together with lysine, methionine and tryptophan, threonine is one of the four major feed additives, mainly used in underage piglets and poultry. Threonine production is an important element in livestock and poultry feeds. Adding threonine to livestock and poultry feeds, threonine protein can improve the biological value of feed protein, balance various amino acids, promote protein deposition, reduce ammonia excretion in animals, reduce environmental pollution and improve feeding conditions.
Threonine is also widely used in the pharmaceutical industry. Its iron salt can be used as an anti-anemia drug, and it can be used to prepare amino acid infusion and comprehensive amino acid preparation, and it also has its own medicinal effects of promoting human development and anti-fatty liver, and it is also an intermediate for the manufacture of highly effective antibiotic monoamide bacteriocin, as well as for biochemical research. Clinically, threonine also has immune-enhancing properties, and threonine protein has a role in promoting the differentiation and development of bone marrow T lymphocyte precursors into mature T lymphocytes.
