Description and Uses

Octanoic acid is a flavoring agent considered to be a short or medium chain fatty acid. It occurs normally in various foods and is commercially prepared by oxidation of n-octanol or by fermentation and fractional distillation of the volatile fatty acids present. It is used in maximum levels, as served, of 0.13% for baked goods; 0.04% for cheeses; 0.005% for fats and oils, frozen dairy desserts, gelatins and puddings, meat products, and soft candy; 0.016% for snack foods; and 0.001% or less for all other food categories.
