Beskrivelse

Gamma-Nonalactone (5-Pentyloxolan-2-one) er en fargeløs til lysegul, oljeaktig væske. Den finnes i bourbon whisky, solbærbær, melon, papaya, ananas, fersk bjørnebær, osv. 1, 2 Den har akremaktig og kokosnøttlignende lukt. 3 Den brukes som smaksstoff i mat for å gi kokosnøtt. Det er også et potensielt lokketrekk for flere arter for kornbagler

Beskrivelse

γ-Nonalactone har en sterk lukt som minner om kokosnøtt og en fet, spesiell smak. Kan syntetiseres ved å reagere metylakrylat og heksanolin i nærvær av ditertiærbutylperoksyd; ved kondensering av undecylensyre og malonsyre; ved lactonizÎ ± - tion av nonenoic acid.

Kjemiske egenskaper

γ-Nonalactone har en sterk lukt som minner om kokosnøtt og en fet, spesiell smak.

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.

Occurrence

Reported found in peaches, apricots, roasted barely, rum, tomato, currants, guava, raisin, papaya, peach, pineapple, blackberry, strawberry jam, asparagus, wheat and crispbread, Camembert cheese, butter, milk, chicken, beef, lamb and pork fat, cooked beef and pork, beer, cognac, whiskies, sherry, grape wines, cocoa, green tea, pecan, oats, soybean, avocado, passion fruit, plum, plumcot, beans, mushroom, starfruit, fenugreek, mango, tamarind, rice, prickly pear, buckwheat, licorice, malt, wort, cherimoya, Bourbon vanilla, shrimp, nectarine, maté and sweet grass oil.

Bruker

(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.

Forberedelse

By reacting methylacrylate and hexanol in the presence of ditertiarybutyl peroxide; by condensation of undecylenic acid and malonic acid by lactonization of nonenoic acid
