DL-Methionine is a sulfur-containing amino acid with the formula C5H11NO2S, also supplied under names such as Racemethionine, Lobamine and DL-Isomer Methionine. In food and beverage production it acts as a nutritional amino acid, contributing to protein building blocks and supporting flavour development through its sulfur chemistry. It falls under the amino acid category and is listed in the EU under Reg. 1333/2008 and Reg. 2015/2283.
Manufacturers use DL-Methionine in savoury flavour systems, seasonings and fermented or protein-based formulations where a sulfur note or amino acid source is wanted. It is a white crystalline powder, freely soluble in water, and typically handled as a dry ingredient under cool, dry conditions away from strong oxidisers. Formulators should note it has a characteristic sulfurous odour and taste, so inclusion levels shape the final profile.
Also known as Racemethionine, Lobamine, DL-Isomer Methionine
