Brief Overview
Methionine is a sulfur-containing amino acid that is essential for healthy and productive poultry. It is important for many different functions in the body. 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.
