| 3-HEPTEN-2-ONE Usage And Synthesis |
| Description | 3-Hepten-2-one is a kind of ketone derivative that can be used as a favoring and fragrance agents. 3-Hepten-2-one belongs to the family of Acryloyl Compounds. It has a powerful, green grassy and caraway odor. It can be used to supply a green note to fruity compositions. It has creamy flavor to be used as caraway, passion fruit and pineapple flavors. This ketone can provide lingering rich after- notes to dairy product such as custard, melted butter, creams and cheers. It is also useful in fatty nut application such as Brazil and pine nuts. It is also useful for the production of heptan-2-one. |
| Chemical Properties | 3-Hepten-2-one has a powerful green-grassy, pungent odor. It may be synthesized by reacting 1-pentyne with acetic anhydride to yield 3-heptyn-2-one, which is then converted to cis-3-hepten-2-one by partial catalytic hydrogenation; the trans-form is probably obtained from trans-2 -hexenic acid treated with methyl lithium. |
| Chemical Properties | 3-Hepten-2-one has a powerful, green-grassy, pungent odor. |
| Occurrence | Reported found in (Byrsinoma crassifolia), red and green pepper, capsicum varieties, hop oil and roasted flbert |
| Preparation | By reacting 1-pentyne with acetic anhydride to yield 3-heptyn-2-one, which is then converted to cis-3-hepten-2-one by partial catalytic hydrogenation; the trans-form is probably obtained from trans-2-hexenic acid treated with methyl lithium. |
| Aroma threshold values | Detection: 56 ppb; aroma characteristics at 1.0%: pungent, dairy, creamy, slightly ketonic, sour milky, blue cheese, waxy, earthy mushroom. |
| Taste threshold values | Taste characteristics at 5 ppm: creamy, dairy, waxy, stale milky, blue cheese and cheese rind with ripe, slightly moldly stale milk with a good mouthfeel. |
