Abstract

A rapid method is described for the colorimetric determination of 1.5–15 μg phytate phosphorus in concentrations as low as 3 μg ml−1 in extracts of cereal grains and cereal products. The phytic acid is precipitated with an acidic iron‐III‐solution of known iron content. The decrease of iron in the supernatant is a measure for the phyticacid content.
