Every second fish and every second shrimp on your plate is now produced by aquaculture—because since the mid-1980s wild capture has been unable to keep pace with demand. But aquaculture too has its limitations: Fish feed contains fish meal and fish oil, which in turn are obtained from fish in the sea.
Fish meal can be partly substituted by plant proteins if certain amino acids such as methionine are added to them. Evonik has done pioneering work on salmon in this field. Shrimps posed more of a problem, however: They eat so slowly that the amino acids have already been leached out of the feed pellets by the time these are consumed.
What would you do, as a creative researcher at Evonik? Our team has analyzed in the greatest detail how shrimp ingest and digest their feed, and has derived the requirements on an optimal methionine source. More than 35 methionine derivatives have been developed and tested in the laboratory, one of which satisfied the criteria regarding water solubility, digestibility, and costs: the dipeptide of DL-methionine. Following many years of research and development work and the construction of a production plant, the patented innovation was finally launched on the market in 2016 under the brand name AQUAVI® Met-Met.
Like all of our 4,000 or so products, AQUAVI® Met-Met is the result of interdisciplinary team work. Depending on your specific qualifications, you too could be working at Evonik on one of the many steps from the next great idea, through product and process development, to production, sales and marketing, and communication.
