• Beschreibung

  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.

• Chemische Eigenschaften

  gamma-Octanoic lactone occurs as an aroma constituent in many processed and unprocessed foods. It is a pale yellow liquid with a fruity/coconut-like odor and is used both in aroma compositions and in heavy blossom perfumes.

  CLEAR COLOURLESS LIQUID

• Occurrence

  Reported found in apricot, peach, blue cheese, butter, cooked chicken and cooked pork, licorice, milk, raspberry, roasted barley, and roasted filbert.

• Verwenden

  4-Octanolide is one of the fine organic aerosol emitted from meat cooking operations that was examined by high-resolution gas chromatography.

• Verwenden

  (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.

• Definition

  ChEBI: Gamma-octalactone is a gamma-lactone that is oxolan-2-one substituted by a butyl group at position 5. It is a volatile compound found in peaches, mangoes, beef and ham. It has a role as a fungal metabolite, a mouse metabolite, a mammalian metabolite, an insect attractant, a plant metabolite and a flavouring agent. It is a gamma-lactone, a tetrahydrofuranone and a volatile organic compound.

• Aroma threshold values

  Detection: 7 ppb; aroma characteristics at 1.0%: sweet, fatty, creamy, coconut, lactonic and coumarinic.

• Taste threshold values

  Taste characteristics at 1 to 10 ppm: coconut, fatty, creamy, coumarinic, with a strong creamy and waxy mouthfeel.
