Description and Uses

y-Octalactone has a strong, fruity odor reminiscent of coconut with a very sweet taste. This substance may be prepared synthetically from epoxy-1,2-hexane and sodio-malonic ester; after saponification the oxyacid is extracted with ether and is lactonized.

(Gamma)-Octalactone is a synthetic flavoring agent that is a stable, colorless to slightly yellow liquid of peach odor. It should be stored in glass or tin containers. It is used in flavors for peach with applications in baked goods, candy, and ice cream at 5–17 ppm.
