At its site in Antwerp (Belgium), Evonik has inaugurated the world's first plant for the production of a new source of methionine specifically designed for shrimp and other crustaceans.
The product* is a dipeptide made up of two DL-methionine molecules, achieves the same weight increase in shrimp and crustaceans as conventional methionine sources, but uses only half the active substance. This is mainly due to the fact that the dipeptide must be enzymatically broken down in the digestive system of the shrimp and is therefore available for protein synthesis at the right time. That in turn means that a higher share can be processed. Evonik also claims that the product is considerably less water-soluble than other methionine sources and therefore does not leach out of feed as quickly. This relieves the burden on the water.

The product is produced in conjunction with an existing methionine plant in a fully backward-integrated process. The environmentally friendly production process is water-based and uses no organic solvents. The Antwerp site with its harbour is an ideal hub for shipping the product to customers worldwide.
The main markets for this aquaculture feed additive ae located in Asia as well as in South and Central America. Evonik is already beginning to supply customers from these regions with the new product as the plant is ramped up to capacity.
