Molar ratio of phytic acid and zinc during cereal flake production

The phytic acid content and distribution of phosphorous during cereal flaking were determined as well as the level of some minerals, and the molar ratios of phytic acid ; zinc were calculated. statistical analyses showed that there were no differences in the amount of total phosphorous, between oats and wheat and between rye and barley. The phytic/non-phytic phosphorous ratio was about 3 in wheat and oats, about 2 in barley and about 13 in rye. The technological processing did not affect P<0.05) phytic acid content. Thje molar ratio of phytic acid : zinc for the flakes was only slightly below that of thwe whole grain, indicating that the technological process, primarily a hydrothermal treatment and flaking, did not improve zina availability.
