| | 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. | | Chemical Properties | 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. | | Uses | 4-Undecanolide is used in the study of primary mutagenicity screening of food additives used in Japan. | | Uses | 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. | | Definition | ChEBI: Xi-gamma-Undecalactone is a lactone. | | Preparation | 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. | | Aroma threshold values | Detection: 60 ppb | | Taste threshold values | Taste characteristics at 30 ppm: fatty, coconut, creamy, vanilla, nutty, macadamia and peach. | | General Description | γ-Undecalactone is a volatile flavor constituent found in low-fat ice cream. | | Flammability and Explosibility | Notclassified |
