L-Threonine is an amino acid with the formula C4H9NO3, also known as threonine or L-2-amino-3-hydroxybutyric acid. In food and beverage production it serves as a building block for protein and contributes to the savoury, rounded taste profile of fermented and hydrolysed ingredients. Its function sits within the amino acid category, where it helps balance flavour and supports the nutritional composition of formulated products. EU Regulation 1333/2008 applies.
Manufacturers use L-threonine in savoury flavour systems, seasonings, sports and clinical nutrition, and fermentation-derived ingredients. It is a white crystalline powder, freely soluble in water, and stable under normal processing conditions. Store it dry and sealed, away from strong odours, since it is hygroscopic and can take up moisture. It is generally handled as a fine powder, so dust control matters in the plant.
