Chemical Information
FooDB Name1-Octen-3-one
DescriptionMushroom flavour component (shiitake, matsutake)and is also present in cranberry, melon, cape gooseberry, peas, potato, mustards, wheat bread, other breads, coriander seed, dill basil varieties and soybean. Contributes to aroma of cooked artichokes (Cynara scolymus) and many other foods Oct-1-en-3-one (CH2=CHC(=O)(CH2)4CH3), also known as 1-octen-3-one, is the odorant that is responsible for the typical metallic smell of metals and blood coming into contact with skin. Oct-1-en-3-one has a strong metallic mushroom-like odor with an odor detection threshold of 0.03 - 1.12 µg/m³ and it is the main compound responsible for the "smell of metal", followed by decanal (smell: orange skin, flowery) and nonanal (smell: tallowy, fruity). Oct-1-en-3-one is the degradative reduction product of the chemical reaction of skin lipid peroxides and Fe2+. Skin lipid peroxides are formed from skin lipid by oxidation, either enzymatically by lipoxygenases or by air oxygen. Oct-1-en-3-one is a ketone analog of the alkene 1-octene. 1-Octen-3-one is found in many foods, some of which are pulses, fruits, herbs and spices, and potato.
