Effects of wheat maturation stage and cooking method on dietary fiber and phytic acid contents of firik, a wheat-based local food.
Samples of two durum wheat cultivars (cvs. Duraking and Ege 88) at different maturation stages (13, 16, 19, 22, 25 days post anthesis) were processed into firik (a wheat-based specialty food) using two different cooking methods: roasting (scorching) on flames and boiling at atmospheric pressure. Both the acid detergent and neutral detergent fiber contents of the firiks produced from two durum wheat samples decreased significantly (p < 0.01) with maturation. Total P contents of the firiks of both cultivars produced by both methods showed a significant downward trend within the period of maturation while their phytic acid contents showed a significant upward trend (p < 0.01). It was possible to obtain a reduced phytic acid, high fiber product from the wheats harvested at early stages of maturation (13 and 16 days after anthesis).
