Докладно

What it is

Decanal is an organic compound with the chemical formula CH₃(CH₂)₈CHO. It is a saturated fatty aldehyde that formally arises from reduction of the carboxy group of capric acid (decanoic acid). Its molar mass is 156.269 g·mol⁻¹.

Occurrence

Decanal occurs naturally in citrus, along with octanal, citral and sinensal. It also occurs in buckwheat and in coriander essential oil. It is a constituent of cassia, neroli and other oils, especially citrus peel oils. It is also present in green tea, hop oil and beer. It has been identified as a volatile component of unpasteurized, fresh orange juice. It has been reported in Camellia sinensis. It is a metabolite found in or produced by Saccharomyces cerevisiae.

Properties

Decanal is less dense than water and floats on it. It is soluble in ethanol, ether and acetone. It is insoluble in glycerol. It is stored in a cool, dry place in tightly sealed containers, protected from heat and light.

Taste

At 30 ppm the taste of decanal is waxy, fatty, citrus and orange peel, with a slight green melon nuance. Another description of its taste is a sharp orange flavor.
