Usage
Production of volatile compounds related to the flavour of foods from the Strecker degradation of DL-methionine.
Addition of methionine in appropriate amounts to these foods might be expected to improve protein value. Economically, DL-methionine would be preferable.
An essential nonpolar amino acid with oxidative stress defense properties
DL-Methionine is sometimes given as a supplement to dogs; it helps keep dogs from damaging grass by reducing the pH of the urine.
Methionine is allowed as a supplement to organic poultry feed under the US certified organic program.
