Fuction:

Threonine can be used in the food industry in nutrition supplements, added to food, L-Threonine can improve the nutritional value of protein, so that adequate food nutrients more reasonable. L-Threonine and glucose were hot, fragrant and easy to produce coke chocolate flavor in a flavor enhancer in food processing role.
L-Threonine in the feed industry, L-Threonine amino acids can be used as feed additives for the feed supply of protein has opened up new avenues, L-Threonine not only improves the nutritional value of feed, reduce feeding costs. But also get to promote animal growth and development, enhance disease resistance and so many other beneficial effects.
L-Threonine is necessary for animals to maintain growth, the animals can not be synthesized. Must be from the food supply. L-Threonine lack can lead to reduced animal intake. Stunted, feed efficiency decreased immune function suppression symptoms. L-Threonine is the second methionine, lysine, tryptophan, essential amino acids after the fourth livestock feed additive, L-Threonine of livestock growth and development, strengthen the fattening, lactation, egg production were significantly facilitating role.
Threonine is an important kind of analeptic which fortifies cereal,pastry and dairy products.Like tryptophan,it rejuvenates human bodies and promotes the growth of infants.When applied in pharmaceutical field,threonine can moisten human skins due to the hydroxy in its structure.Combined with oligose,it protects human cell membranes,and accelerates the synthesis of phosphatide and the oxidation of fatty acid.With a medicinal effect of preventing fatty liver,threonine preparation works as a component of compound amino acid injection,Meanwhile,threonine can be used for the production of monobactams,one of high-effect and low-allergy antibiotics.

As amino acid for forge,threonine is widely added in the forage for newborn pig,covering pig,poultry,shrimp,eel and so.It can:
--Keep the balance of amino acids in the forage and stimulate the growth of the animals;
--Improve the meat quality;
--Increase the nutritive value of forage raw materials which have low amino acid digestibility;
--Apply to the production low-protein forage;
--Cut down the cost of raw materials for forage;
--Decrease the nitrogen content in the excrement and urine of animals so that the release of ammonia is slowed and the ammonia concentration is kept low in animal shed.
