Multi-element rice grains analysis by ICP OES and classification by processing types

閱讀：1635 發(fā)布時(shí)間：2020-10-30

As major food staple, rice (Oryza sativa L.) is c*ted in irrigated fifields absorbing widely trace elements wich may or may not migrate during processing types. Thus, we aimed to evaluate fifive national rice brands found in local market, in order to verify concentration of elements As, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Mo, Na, Ni, Pb, Sb, Se, Sn, Sr, V, Tl and Zn, presenting the difffferences and migration patterns between brown, parboiled and

polished rice for each brand. Data were evaluated using ANOVA, post-hoc Tukey and PCA. The two major components presented 94.33% variance, indicating strong difffferentiation in samples by their processing types from their mineral composition. K is widely distributed over the grain, Mg, Fe and Ba are more distributed in the outer layers being more susceptible to loss, and Ca, Sr and Zn are more sensitive to the parboiling hydrothermal

process.
