Chemical Information
FooDB NameOctanoic acid
DescriptionWidespread in plant oils, free and as glyceridesand is also present in apple, banana, orange juice and peel, pineapple, cognac, calamus, blue cheeses, cheddar cheese, Swiss cheese, feta cheese and other cheeses. Flavouring agent, defoamer, lubricant, binder and antimicrobial preservative in cheese wraps Caprylic acid is the common name for the eight-carbon saturated fatty acid known by the systematic name octanoic acid. It is found naturally in the milk of various mammals, and it is a minor constituent of coconut oil and palm kernel oil. It is an oily liquid that is minimally soluble in water with a slightly unpleasant rancid-like smell. Octanoic acid is found in many foods, some of which are salad, mango, ice cream, and anise.
