Nutrients, phytochemicals and antioxidant activity in whole and dehulled nutri-cereal based multigrain extruded snacks
Abstract
The extrudates were prepared from the multigrain flour mixture either whole grain flour (WGF) or dehulled grain flour (DGF) comprising of 15% of sweet potato flour, 30% cereal and pulse flour (Bengal gram+ defatted soya bean flour + rice in equal proportion) and 55% of millet flour (Pearl millet+ Foxtail millet + Ragi in equal proportion). It was found that there was no significant difference between WGF/WGE and DGF/DGE in moisture and ash (P>0.05). Significantly higher protein (15.31g/100g), dietary fibre (12.5g/100g), Iron (28.70 mg/100g), zinc (6.60mg/100g), higher phenolics (65.8mg/100g), phytates (326.25 g/100g) were found in WGE compared to DGE. While DGE has higher soluble fibre content than that of WGE. The antioxidant activity measured by radical scavenging activity exhibited significantly (P
