Chemische Eigenschaften
gamma-Undecalactone has a strong, fruity odor suggestive of peach (particularly on dilution). It has a pungent and sweet flavor also similar to peach.
Chemische Eigenschaften
GAMMA-UNDECALACTONE is clear colourless liquid
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.
Verwenden
Traditionally, the bark and leaves of the peach tree have been used as an anthelmintic, an expectorant, an astringent, and a diuretic, as well as to treat insomnia, cough, and constipation. In the 1970s, peach pits (Laetrile) were a popular but unproved treatment for cancer in other countries. Topically, peach is used to treat minor skin disorders such as burns, abrasions, blisters, scratches, eczema, psoriasis, and warts.
Verwenden
4-Undecanolide is used in the study of primary mutagenicity screening of food additives used in Japan.
synthetische
By the action of sulfuric acid on undecylenic acid; also prepared starting form castor oil; from octanol-1 plus methylacrylate with di-ter-butylperoxide; from heptylethylene oxide and sodiomalonic ester.
