Determination of Iron, Zinc and Manganese in Nine Varieties of Wheat (Triticum aestivum L.) and Wheat Flour by using Atomic Absorption Spectrophotometer

G. Q. Shar, T. G. Kazi, M. A. Jakhrani and S. R. Sahito
Mineral elements compositions were estimated in local wheat and wheat flour samples by standard analytical methods coupled to the atomic absorption technique. The estimated significant quantities of three essential elements such as Iron (Fe), Zinc (Zn) and manganese (Mn) were determined by the atomic absorption spectrophotometer. The reference samples was obtained from the "Seed certification and Registration Department, Islamabad" as a reference material, while as representative samples were collected from different areas of Pakistan. In present work the essential elements iron, zinc and manganese were determined in different nine varieties of wheat grain and wheat flour, using atomic absorption spectrophotometer. It was observed that the level of Fe was high in Rohtas-90 (29.0-30.8) and low in Shahkar-91 (18.3-20.1) mg kg-1. The level of Mn was high in Khyber-87 (41.8-48.4) and low in Rohtas-90 (25.0-27.4) mg kg-1. The concentration of Zn was high in Khyber-87 (30.2-34.9) and low in Rohtas-90 (21.2-22.2) mg kg-1.
