The complex process of manufacturing methionine

Companies harness nature to make feed amino acids via fermentation, but the presence of a sulphur atom has thwarted a similar approach for methionine. Instead, it is made via a complex chemical synthesis involving hard-to-handle raw materials such as methyl mercaptan, propylene and hydrogen cyanide. Manufacturer Adisseo recently offered a look behind the scenes to show what constraints cross their path at their plant in Les Roches de Condrieu, south of Lyon in France. Methionine (Met) is defin
