Maize and amaranth ratio varied in order to assess the combination which had the highest nutritive value in terms of iron and other micronutrients (zinc and calcium) and lowest phytate
Doolette AL, Smemik RJ, Dougherty WJ (20116) Overestimation of the importance of phytate
in NaOH-EDTA soil extracts as assessed by 3IP NMR analyses.
One of adverse effects of phytate
is redution in digestive enzymes activity.
Indian diet, low in calcium and high in phytates
, may also contribute by causing secondary hyperparathyroidism, increased conversion of 25OHD to polar metabolites and inactive 24, 25 dihydroxyvitamin D3 (26,27).
This allows them to make a special enzyme (protein that speeds up chemical reactions) that alters the phytate
in their diet.
Effect of phytate
and storage conditions on the development of the hard to cook phenomenon in common beans.
84 gm sodium phytate
in 90 ml acetate buffer, pH 5.
Such diets or dietary compositions consist largely of cereals and legumes which contain high levels of phytate
, a potent antagonist of zinc absorption (Gibson 2005:714, 717; Mazariegos et al.
Working with laboratory cultures of human digestive system cells, the researchers also determined that polyphenols may have a more significant role in blocking the body's iron uptake than does phytate
, a plant compound known to interfere with iron uptake.
The enzyme can be produced from native or recombinant host cells and can be used to aid in the digestion of phytate
in cereal can interfere with oral iron absorption
Appropriate resin selection for rapid phytate
analysis by ion-exchange chromatography.
