Chemical Properties

GAMMA-UNDECALACTONE is clear colourless liquid

Chemical Properties

gamma-Undecalactone has a strong, fruity odor suggestive of peach (particularly on dilution). It has a pungent and sweet flavor also similar to peach.

Occurrence

Reported found in hydrolyzed soy protein, butter, peach, apricot and passion fruit. Also reported found in fresh apple, guava fruit, fresh blackberry, heated butter, heated beef fat, ghee, pork fat, yellow passion fruit juice, cooked scented rice, origanum (Spanish) (Coridothymus cap. (L.) Rchb.), mountain papaya, starfruit, plumcot and chicken fat.

Topically, peach is used to treat minor skin disorders such as burns, abrasions, blisters, scratches, eczema, psoriasis, and warts.

Uses

4-Undecanolide is used in the study of primary mutagenicity screening of food additives used in Japan.
