By producing methyl groups, methionine is responsible for a variety of metabolic reactions. It is also essential for cell proliferation and development.

Manufacturing Process

The process of producing methionine comprising the following steps: a first step of converting raw material capable of producing methionine through hydrolysis of 2-amino-4-methylthiobutyronitrile, and 2-amino-4-methylthiobutanamide or the like in an aqueous ammonia solution, into methionine-containing aqueous ammonia solution, with a biocatalyst through hydrolysis. The second step of separating the biocatalyst from the methionine-containing aqueous ammonia solution obtained in the first step. The third step of distilling ammonia out of the product of the second step to deposit and separate crystals of methionine.


Animal Feed Industry

DL-Methionine is an essential nutrients to build protein-block. It plays important roles to overall growth and development of animals. It is available in limited amount in plant, therefore herbivores like poultry and cattle need extra supplementation of methionine. Methionine in poultry also heps feather growth.
