C6H6[OPO(OH)2]6 An acid found in seeds of plants as the insoluble calcium magnesium salt (phytin); derived from corn steep liquor; inhibits calcium absorption in intestine; used to treat hard water, to remove iron and copper from wines, and to inactivate trace-metal contaminants in animal and vegetable oils.

One study found that if you can remove phytic acid entirely from grains (likely impossible), you'll improve your iron absorption by three times in the case of rice and nearly twelve times for wheat.
Phytic acid is present in higher concentrations in legumes than in cereals and bread.
Phytic acid was extracted in 0.5M nitric acid by shaking at room temperature for 3h and determined spectrophotometrically at 512nm, as described by Davies and Reid (1979).
"The other consequence of the refining process includes loss of fiber, vitamins, magnesium and other minerals, lignans, phytoestrogens and phytic acid, many of which may be protective factors for diabetes risk," they added.
Some areas described are remanufacturing and automatic surface engineering technology, plasma transferred arc powder surfacing technology of thrust face, cerium- phytic acid passivation treatment on galvanized steel, supersaturated surface engineering S-phase materials, and preparation of epoxy modified organosilicone high-temperature resistance coatings.
Fermentation improves its digestibility and degrades phytic acid content, which reduces nutrient assimilation (zinc, calcium, and magnesium) and cause painful gases.
In this article, we prepared polysilsesquioxanes via sol-gel process of methyltriethoxysilane (MTES), 3-glycidoxypropyltrimethoxysilane (GPMS), and tetraethoxysilane (TEOS) using phytic acid, tannic acid, and 1-hydroxyethylidene-1,1-diphosphonic acid (HEDPA) (whose structures were present in Scheme 1) as the catalyst, respectively.
Wholegrain bread, brown pasta and rice as well as some breakfast cereals such as Shredded Wheat are all rich in the antioxidants vitamin E, phenolic acid and phytic acid which have been shown to protect against asthma in children.
