Abstract:
Biofortified (PBW 1 Zn) wheat flour was fractionated into three fractions (355, 180 and 150 µm) and evaluated for physicochemical, functional, rheological, biochemical and chapatti making parameters. With decreasing flour particle size the ash, fat, fibre, phytic acid, antioxidant activity, total phenolic content and pasting properties decreased, whereas carbohydrates, zinc, lightness (L*) and functional parameters increased. Chapatti making quality of flour fraction (180 μm) was observed best on the basis of puffing height (7.64 cm), extensibility (1.83 N) and sensory quality with best overall sensory scores (8.75). The results indicate that reducing the particle size to 180 μm could improve the nutritional, functional and chapatti making quality of wheat flour.
