Studying concentration of minerals in some local and imported rice by using energy-dispersive X-ray fluorescence (EDXRF)‎

الملخص EN

Rice is an important food in the world, particularly in Asian countries, it is consumed as a staple food.

This study analyzes the 5 different samples (imported basmati rice such as India-1, India-2, India-3, Iraqi- PDS, Russian and local Kurdish rice) by using most covenant, economical technique Energy-dispersive X-ray Fluorescence (EDXRF) spectroscopy).

Techniques were used after grounding, and pressing the samples in the sample containers to analyze 15 minerals (Al, Ca, Cl, Cr, Fe, K, Mg, Mn, P, S, Si, Ti, Zn, Na, and Sr).

The results of variance showed that there is a significant difference (p<0.01) in the minerals content of the rice samples and the main trends show that all rice samples were not contained sodium (Na) and strontium (Sr).

On the other hand, the dominant minerals in all samples were silicon (Si) > phosphate (P) > Sulfur (S) than other minerals, while rice as a plant is considered to be one of the most accumulator of Si, P and S minerals.

In conclusion, EDXRF offers a reliable and fast approach to screen of minerals in different sample of foods and the differences in minerals content in the study may refer to the influence of different factors such as irrigation, rice verities, type of soil, and Rice is an important food in the world, particularly in Asian countries, it is consumed as a staple food.
