摘要：Wheat flour samples (n=40) in triplicates of two different varieties (fine and super) were collected from various sources (Mills and Chakis) of Hazara Division, KP, Pakistan. Samples were analyzed for nutritional quality parameters (pH, moisture, ash, protein, hardness and wet gluten) by using standard methods and micro, macro and toxic elements by using Atomic Absorption Spectrometry (AAS). All the parameters exhibited significant variations in outcomes of two different sources and two varieties. Low wet gluten (10.70 to 19.33% in Mills and13.73 to 26.23% in Chakkis) and high ash contents (1.73 to 10.86% in Mills and 1.8 to 11.06% in Chakkis) were observed during analysis. The concentrations of the micro and macro elements were found in the following order Mg > Ca > Fe > Zn > Cr>Mn > Cu >Ni while the concentrations of the toxic metals in samples of both the sources were detected in the following order Pb > Cd > As. Different concentrations of toxic, essential elements and physicochemical variations provide basis that a detailed survey should be conducted to assess the nutritional worth and health risks based on staple food among Pakistani population.
