Description and Uses
y-Heptalactone has a sweet, nut-like, caramel odor and a malty, caramel, sweet, herbaceous taste. This substance may be obtained in low yields by hydrogenation of ethyl P-furylacrylate;1 by lactoniation of heptenoic acid; also by condensation of methylacrylate butyl alcohol using a catalyst.
Food additive.
