Butyl Butyryllactate is a synthetic flavoring agent that is a stable,
colorless to light yellow liquid with the odor of cooked butter. it is
miscible with alcohol and most fixed oils, soluble in propylene glycol,
and insoluble in glycerin and water. it should be stored in glass, tin,
or resin-lined containers. it is used in butter flavors with applica-
tions in baked goods and candy at 14–60 ppm.
Definition
ChEBI: Butyl butyryllactate is a diester resulting from the formal condensation of the carboxy group of 2-(butanoyloxy)propanoic acid with butan-1-ol. It has a role as a flavouring agent and a plant metabolite. It is a diester and a butyrate ester. It is functionally related to a 2-hydroxypropanoic acid and a butan-1-ol.
Preparation
Butyl butyryllactate is prepared by acylation-esterification of Lactic acid.
