Methionine lecture hall-1 Common forms and production processes of methionine

Common forms of methionine3kE China Feed Industry Information Network-Based on feed, serving animal husbandry

Methionine, also known as methionine, is an essential amino acid in the growth process of all animals, but it cannot be synthesized by the animal itself and needs to be obtained from feed

L-methionine (L-Met)3kE China Feed Industry Information Network-Based on feed, serving animal husbandry

Since methionine molecules have asymmetric carbon atoms, methionine can be divided into D-type (right-handed body) and L-type (left-handed body).

D,L-methionine is a racemic mixture composed of 50% D-methionine and 50% L-methionine

Whether it is D,L-methionine or D,L-hydroxymethionine, they are all produced on a large scale through chemical synthesis

Although they have different production processes, they all use a common key intermediate-3-methylthio-propionaldehyde (MTPA) to start the synthesis

Some manufacturers, such as Adisseo, have mastered a comprehensive production process and can fully integrate upstream and downstream processes.

　　It should be pointed out that most of the raw materials and intermediates in the methionine production process are toxic substances, so safety is the primary consideration for the production plant, which includes the storage of raw materials and intermediates, and processing steps
