Undecan-4-olide Chemical Properties,Usage,Production

Description

GAMMA-UNDECALACTONE  is a flavoring ingredient. It is industrially important flavor compounds that are widely distributed in foods, fruits, and beverages and are used in many fruity aromatic foods and cosmetics. It is often used in peach, apricot, pear, maple, coconut, tropical, butterscotch, grenadine and date flavors. It is also a volatile flavor constituent found in low-fat ice cream.

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.

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.

Uses

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

Definition
