Phytic acid (known as inositol hexakisphosphate (IP6), inositol polyphosphate, or phytate if in alkali form), apparent in 1903, a saturated circadian acid , is the arch accumulator anatomy of phosphorus in abounding bulb tissues, abnormally bran and seeds. It can be begin in cereals and grains.

Phytic acid is begin aural the hulls of nuts, seeds, and grains. In-home aliment alertness techniques can breach down the phytic acid in all of these foods. Simply affable the aliment will abate the phytic acid to some degree. Added able methods are assimilation in an acid medium, lactic acid fermentation, and sprouting.

Phytic acid has a able bounden affection to important minerals, such as calcium, iron, and zinc, although the bounden of calcium with phytic acid is pH-dependent. The bounden of phytic acid with adamant is added complex, although there absolutely is a able bounden affinity, molecules like phenols and tannins aswell access the binding. If adamant and zinc bind to phytic acid they anatomy baffling accelerate and are far beneath absorbable in the intestines. This action can accordingly accord to adamant and zinc deficiencies in humans whose diets await on these foods for their mineral intake, such as those in developing countries and vegetarians.

As a aliment additive, phytic acid is acclimated as the bactericide E391.
