Food grade L-Threonine application:
1. Nutritional additives. Also for the preparation of amino acid infusion and comprehensive amino acid preparations.
2. Threonine is an important nutrient enhancer, being able to strengthen the grains, cakes and dairy products with similar effects of restoring human fatigue, promoting growth and development as tryptophan. In the field of medicine, due to that the structure of threonine contains hydroxyl, it has a water retention effect in human skin, can be combined with the oligosaccharide chain and play an important role in the protection of cell membranes. It can also promote phospholipid synthesis and fatty acid oxidation in vivo.
Feed grade L-Threonine application:
L-Threonine is an essential amino acid that is added to the diet of pigs and poultry in order to exactly match the balanced amino acid requirement of the animals. In practice, L-Threonine is the second limiting amino acid for pigs and the third for poultry.
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.

L-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.
