Caproic acid is a fatty acid found naturally in various animal fats and oils, and is one of the chemicals that gives the decomposing fleshy seed coat of the ginkgo its characteristic unpleasant odor.
Caproic acid is also one of the components of vanilla and cheese.
The primary use of caproic acid is in the manufacture of its esters for use as artificial flavors, and in the manufacture of hexyl derivatives, such as hexylphenols.
Salts and esters of caproic acid are known as caproates or hexanoates.
Several progestin medications are caproate esters, such as hydroxyprogesterone caproate and gestonorone caproate.

Currently, caproic acid is produced from food crops like palm and coconut, with oils containing less than one percent of caproic acid.
Although the caproic acid produced from food crops is commercially available, the low caproic acid content in these crop oils leads to a high price and a limited market.
Recently, an industrially applicable caproic acid production process using mixed organic waste as a feedstock was developed and implemented, based on a microbial fermentation process, that is, chain elongation.

Caproic acid is a carboxylic acid. Carboxylic acids donate hydrogen ions if a base is present to accept them.
Caproic acids react in this way with all bases, both organic (for example, the amines) and inorganic.
Their reactions with bases, called "neutralizations", are accompanied by the evolution of substantial amounts of heat.
Neutralization between an acid and a base produces water plus a salt.
Caproic acids with six or fewer carbon atoms are freely or moderately soluble in water; those with more than six carbons are slightly soluble in water.
Soluble Caproic acid dissociate to an extent in water to yield hydrogen ions.
The pH of solutions of carboxylic acids is therefore less than 7.0.
Many insoluble carboxylic acids react rapidly with aqueous solutions containing a chemical base and dissolve as the neutralization generates a soluble salt.
Caproic acids in aqueous solution and liquid or molten carboxylic acids can react with active metals to form gaseous hydrogen and a metal salt.
Such reactions occur in principle for solid carboxylic acids as well, but are slow if the solid acid remains dry.
Even "insoluble" carboxylic acids may absorb enough water from the air and dissolve sufficiently in it to corrode or dissolve iron, steel, and aluminum parts and containers.
Caproic acids, like other acids, react with cyanide salts to generate gaseous hydrogen cyanide.
The reaction is slower for dry, solid carboxylic acids.
Insoluble carboxylic acids react with solutions of cyanides to cause the release of gaseous hydrogen cyanide.
Flammable and/or toxic gases and heat are generated by the reaction of carboxylic acids with diazo compounds, dithiocarbamates,isocyanates, mercaptans, nitrides, and sulfides.
Caproic acids, especially in aqueous solution, also react with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), to generate flammable and/or toxic gases and heat.
Their reaction with carbonates and bicarbonatesgenerates a harmless gas (carbon dioxide) but still heat.
Like other organic compounds, carboxylic acids can be oxidized by strong oxidizing agents and reduced by strong reducing agents.
These reactions generate heat.
A wide variety of products is possible.
Like other acids, carboxylic acids may initiate polymerization reactions; like other acids, they often catalyze(increase the rate of) chemical reactions.
This compound reacts with bases, oxidizing agents and reducing agents.
The common name for hexanoic acid, a short-chain saturated fatty acid that can be created by the metabolic activity of yeasts.
Caproic acid is one of three fatty acids named in relation to Capra, the genus of goats; the others are caprylic and capric acids.
The names are derived from the high amounts of these fatty acids found in goat's milk, which give the milk its characteristic odor and flavor.
Caproic acid gives a normal flavor in goat's milk, but Caproic acid is usually not desirable in beer.
In beer Caproic acid has a pungent, sweaty, cheesy aroma.
Caproic acid is excreted by yeast during extended lagering at warm temperatures and high yeast cell counts.
The condition of the yeast also influences fatty acid excretion and beers fermented warm under pressure show increased concentrations of these fatty acids (and corresponding esters) during lagering.
Normal amounts of Caproic acid are in the 1-2 ppm range, whereas increased amounts can have negative effects on both foam and taste.
To avoid these effects, brewers often remove yeast as soon as feasible after fermentation.
Where time is an issue, a entrifuge is sometimes used between fermentation and lagering tanks, although in this case the process is usually calibrated to leave some yeast behind to assist in maturation.
Caproic acid is a major feature of lambic aromatics and beers intentionally inoculated with Brettanomyces cultures will often show distinctly funky characteristics.
