Uses Butyric Acid is a fatty acid that is commonly obtained from butter fat. it has an objectionable odor which limits its uses as a food acid- ulant or antimycotic. it is an important chemical reactant in the manufacture of synthetic flavoring, shortening, and other edible food additives. in butter fat, the liberation of butyric acid which occurs during hydrolytic rancidity makes the butter fat unusable. it is used in soy milk-type drinks and candies.

Uses It is used in plastics as a raw material for the cellulose acetate butyrate (CAB). Other uses of butyric acid are in disinfectants, pharmaceuticals, and feed supplements for plant and animals. Butyric acid derivatives play an important role in plant and animal physiology.

Uses Butyric acid is used in the preparation of various butyrate esters. Low-molecular-weight esters of butyric acid, such as methyl butyrate, have mostly pleasant aromas or tastes. As a consequence, they find use as food and perfume additives. It is also used as an animal feed supplement, due to the ability to reduce pathogenic bacterial colonization. It is an approved food flavoring in the EU FLAVIS database (number 08.005).

Due to its powerful odor, it has also been used as a fishing bait additive. Many of the commercially available flavors used in carp (Cyprinus carpio) baits use butyric acid as their ester base; however, it is not clear whether fish are attracted by the butyric acid itself or the substances added to it. Butyric acid was, however, one of the few organic acids shown to be palatable for both tench and bitterling. The substance has also been used as a stink bomb by Sea Shepherd Conservation Society to disrupt Japanese whaling crews, as well as by anti-abortion protesters to disrupt abortion clinics.
