DETERMINATION OF SELENIUM CONCENTRATION IN DIFFERENT SPECIES OF RICE CONSUMED IN BANDUNG INDONESIA

Abstract

Selenium deficiency may lead to the development of several diseases, including cardiovascular diseases and cancer. Due to body selenium concentration is solely depend to its daily intake, monitoring the selenium level of daily consumed foods is critical for the prevention of selenium deficiency-related diseases. In this study, we investigate the selenium concentration of daily consumed rice as the staple food in Bandung City of West Java Province of Indonesia. Twenty different species of rice were collected from the local market, wet digested, and analyzed for selenium concentration using Atomic Absorption Spectrophotometry. The results showed that the selenium concentration of rice consumed in Bandung were varied with the lowest was 0.011 µg/g given by IR64 species growth in Sumedang area, while the highest was 0.071 µg/g given by HD species growth at Cianjur area. Meanwhile, the mean selenium concentration of rice consumed in Bandung was 0,035 µg/g. To our knowledge, this is the first report on the selenium level of rice in Indonesia. Altough it only reported the result from Bandung, however, as it is one of the largest city in Indonesia with the daily consumed foods mainly originated from outside of the city, this result may describe the picture of selenium concentration of Indonesian rice.
