Phytic acid chelate minerals, including Fe and Zn and render them inaccessible once ingested by human beings. The evaluation of differences in the dialyzability of macronutrients including Fe and Zn in various wheat derivatives is therefore important for the enhancement of nutritional quality of grains. Objectives: The objective of current study was to improve the micronutrient content in wheat grain. Methods: During germination (12, 24, 48, 72, 96 h), effects of gibberellins and ascorbic acid on phytic acid content as well as dialyzability of iron and zinc of wheat derivatives were determined. Results: The phytic acid content in wheat flour was determined and it was found 7.61 to 7.48 mg/g. After the treatment with gibberellins, it was significantly reduced from 8.68 to 21.6 % and 9.65 to 20.9 % with ascorbic acid. In wheat flour dialyzabilty of Fe was 4.53 to 8.97 mg/kg. After germination, Fe content was increased from 9.77 to 32.0 % with gibberellin, and 13.9 to 31.0 % with ascorbic acid. Moreover, with gibberellins, Zn content was increased from 8.68 to 21.6 % and 9.65 to 20.9 % with ascorbic acid, respectively. Conclusion: These results suggested that gibberellins as well as ascorbic acid can be exploited to improve the dialyzability of iron and zinc content due to reduced antinutrient i. e phytic acid and make the minerals available for the absorption in monogastric animals including human beings.
