摘要：
Mineral elements fingerprinting is applied for quality control detection of agricultural products. The content of the mineral elements in rice is not only related to genotype, environment factors, but also the processing precision. As a major influence factor for mineral elements distribution in rice, it deserves further study. Rice variety of Longjing-40 was taken as the model material in this study, which was divided into 5 grades under different precision levels. Inductively coupled plasma mass spectrometry (ICP-MS) and X-ray photoelectron spectroscopy (XPS) were applied for mineral elements contents detection in rice. The contents of Na, Mg, Al, Ca, V, Cr, Mn, Fe, Co, Cu, Zn, Rb, Sr, Mo, Cs and Ba were notably different in different precision levels of rice. The data suggest that the content of Na, K, Ca, Fe were significantly higher in outer layer of rice, and were lower in the middle layer and near middle of rice. The results show that the contents of Na, Mg, Al, Ca, V, Cr, Mn, Fe, Co, Cu, Zn, Rb, Sr, Mo, Cs and Ba are significantly different among different processing precisions. The contents of Na, Ca and Fe in different parts of rice grains are different. The content of Na, K, Ca and Fe on the surface of the caryopsis is higher, and that is lower in the near center parts and center parts of the rice, indicating that Na, K, Ca and Fe are mainly enriched in the outermost layer of brown rice (mainly the bran layer and the outer endosperm layer). The processing precision is one of the main factors that should be considered in the research of rice mineral element fingerprint analysis technology. © 2019, Editorial Office of Journal of CIFST.
