| | 4-Heptanolide Usage And Synthesis |
| Description | 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. | | Chemical Properties | γ-Heptalactone has a sweet, coconut-like, caramel and a malty, caramel, sweet odor, and herbaceous taste. | | Chemical Properties | Clear colorless to pale yellow liquid | | Occurrence | Reported found in green tea, asparagus, beer, strawberry, peach and beef | | Uses | Food additive. | | Preparation | Obtained in low yields by hydrogenation of ethyl β-furylacrylate; by lactoniation of heptonic acid; also by condensation of methylacrylate butyl alcohol using a catalyst. | | Definition | ChEBI: Dihydro-5-propyl-2(3H)-furanone is a lactone. | | Aroma threshold values | Detection: 400 ppb. | | Taste threshold values | Taste characteristics at 15 ppm: sweet, lactonic, creamy, coconut and coumarin, with milky and tobacco Nuances. | | Synthesis Reference(s) | Journal of the American Chemical Society, 99, p. 7360, 1977 DOI: 10.1021/ja00464a048 | | General Description | γ-Heptalactone is a volatile flavor compound found in mangoes, strawberries, pineapples as well as in some dairy products.
