It is used in oral care formulations to round out mint notes and in coffee flavors.
Definition
ChEBI: Alpha-angelica lactone is an angelica lactone and a butenolide. It is functionally related to a but-3-en-4-olide. It is a tautomer of a beta-angelica lactone.
Preparation
By dry distillation of levulinic acid
Taste threshold values
Taste characteristics at 100 ppm: sweet, creamy, coconut, vanilla hay and coumarin-like nuances
General Description
α-Angelica lactone, a cyclic lactone that occurs naturally in tobacco, is generally used in tobacco flavoring.
