Application:

Methionine is a "skeleton" amino acid of biosynthetic protein. It is one of the essential amino acids for the growth of poultry animals. It has a strong regulatory effect on animal metabolism and is widely used in feed, medicine, food and cosmetics.

In the feed industry, the largest amount of methionine is used as a nutritional supplement for feed, a feed additive that compensates for the balance of amino acids, and 1 kg of methionine is added to the feed, which is equivalent to the nutritional value of 50 kg of fishmeal. The amount of methionine added to the feed is generally from 0.05% to 0.2%.]

In medicine, methionine can be used as a main component of amino acid infusion and complex amino acids, and can also be used for synthesizing medicinal vitamins, and can be used for producing liver-protecting preparations by utilizing its anti-fatty liver function.

In terms of food, methionine is used for the amino acid strengthening of foods and the processing of food health products, and can be used as a nutritional supplement.
