Abstract

In the current study, starch was isolated from two Egyptian wheat cultivars, namely, Wheat Durum BeniSuef 1 and Bread Wheat Misr 1. The isolated starches were subjected to versatile physicochemical study, comprising, proximate analyses (contents of ash, moisture, protein, total carbohydrates), total organic matter (TOM), total organic carbon (TOC), undesired elemental content (chromium, nickel, arsenic, lead and cadmium), nutritive elemental content (sodium, potassium, phosphorus, magnesium, calcium, manganese, iron, cobalt, copper, zinc and selenium), other elements (molybdenum, tin and antimony),  amylose, amylopectin, pH value, water binding capacity (WBC), total hydrolysable carbohydrates, swelling power and solubility. Spectral studies including Fourier transform infrared (FT-IR) and X-Ray diffraction pattern of the isolated starches were thoroughly envisaged.
