الملخص

Care of human health is one of the most important world’s research areas. Nutrition has the primary care, so food was continuously checked and monitored to discover its nutritional elements and characteristics in order to decide whether the elements are sufficient or insufficient for human body. Consequently, the organizations and institutions have been established to monitor and regulate the food standards. Among the continuously consumed food is oil which is almost used every day. This study aimed to test some physical characteristics of edible oils such as ( density, refractive index and viscosity), in addition to measuring the metallic contaminates by using fluorinated X-ray by (X-met 5000) device. Three samples have been selected; sesame oil, peanut oil and mixed oil to identify whether they correspond with the specifications of the Sudanese Standards and Metrology organization) SSMO(, and to measure the metallic contaminates concentrations . The results show that the refractive index of sesame oil is (1.4645) which is less compared to the refractive index at the (SSMO), while the density is (0.916 g/ml) which corresponds with the (SSMO) . As for sesame oil’s viscosity, it is (85 mpAs). The refractive index of peanut oil is (1.4777) which is higher than the (SSMO), (0.912, 0.920 g/ml) and the viscosity is (85 mPAs). The refractive index of the mixed oil is (1.4812) which is higher than the (SSMO) (1.4710, 1.4585) and the density is (0.973 g/ml) which is also higher than the (SSMO) (0.925, 0.914) and the viscosity is (55 mPAs). The results of concentrations of metallic contaminates measured by (X-met 5000) are as follows: Sesame oil (Fe 0.05%, Pb 0.00, Ni 0.01%, Cr 0.03%), Peanut oil (Cr 0.03%, Fe 0.05% , Pb 0.01%, Ni 0.00) and Mixed oil ( Ni 0.01%, Pb 0.01%, Fe 0.05%, Cr 0.03%). This study recommends using XRF on other oils to check their metallic contaminates.
