gamma-Nonanolactone Usage And Synthesis |
||||
|
Description |
Gamma-Nonalactone (5-Pentyloxolan-2-one) is a colorless to pale yellow clear oily liquid. It is found in bourbon whiskey, black currant berries, melon, papaya, pineapple, fresh blackberry, etc.1,2 It has a creamy and coconut-like odor.3 It is used as a flavoring agent in food to give coconut flavor. It is also a potential multi-species attractant lure for grain beetle pests.4 |
|
Description |
γ-Nonalactone has a strong odor reminiscent of coconut and a fatty, peculiar taste. May be synthesized by reacting methylacry- late and hexanol in the presence of ditertiarybutyl peroxide; by condensation of undecylenic acid and malonic acid; by lactonizα- tion of nonenoic acid. |

Chemical Properties |
γ-Nonalactone has a strong odor reminiscent of coconut and a fatty, peculiar taste. |
|
Chemical Properties |
gamma-Nonanolactone occurs in many foods and is a pale yellow liquidwith a coconut-like aroma. It has numerous applications, similarly to those of ??-octalactone, in aroma compositions and perfumery. |
|
Uses |
(Gamma)-Nonalactone is a synthetic flavoring agent that is a colorless to yellow liquid of strong, coconut-like odor. It is soluble in most fixed oils, mineral oil, and propylene glycol. It is stable in acids and unstable in alkali and should be stored in glass, tin, or aluminum containers. It is used in coconut flavors and has application in gelatins, puddings, baked goods, candy, and ice cream at 11–55 ppm. It is also termed aldehyde c-18. |
|
Preparation |
By reacting methylacrylate and hexanol in the presence of ditertiarybutyl peroxide; by condensation of undecylenic acid and malonic acid by lactonization of nonenoic acid |
|
Aroma threshold values |
Detection: 7 ppb |
|
Taste threshold values |
Taste characteristics at 10 ppm: coconut, creamy, waxy with fatty milky notes |
|
Safety Profile |
Moderately toxic by ingestion. A skin irritant. Mutation data reported. Combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes. See also ALDEHYDES. |
