Acetoin (3-Hydroxy-2-butanone) is a food-grade natural butter-flavour compound used as a food flavouring agent for buttery, creamy notes in dairy, bakery and savoury applications.We supply bulk Acetoin sourced from leading China manufacturers, available in liquid form to meet global food industry demand. Our Acetoin is widely used in dairy flavouring, snack flavouring, confectionery flavouring, spread flavouring and savoury food flavour enhancement.
Acetoin is a naturally occurring ketol found in butter, yoghurt, wine and fermented foods.
It provides the characteristic buttery, creamy flavour and is biosynthesised by many microorganisms including lactic acid bacteria. Commercially produced by fermentation or synthesis, it is used as a GRAS flavouring agent in food to impart or enhance buttery notes in dairy, bakery, popcorn, confectionery and savoury products.
