富硒水稻的营养成分及重金属研究

Studies on nutrient components and heavy metals of Se-enriched rice

以安康市不同种富硒水稻为原料,测定其水分、可溶性总糖、蛋白质以及重金属(镉、铅、汞)含量,研究富硒水稻中硒元素的存在是否会引起水稻中营养成分的减少或重金属含量的增加。结果表明,富硒水稻中的水分(8.047~14.055 g/100 g)、可溶性总糖(6.09~9.39 mg/g)、蛋白质(7.714~9.225 g/100 g)、汞(0.0137~0.0172 mg/kg)、铅(0.089~0.162 mg/kg)、镉(0.074~0.171 mg/kg)均符合国家标准。富硒水稻完全可以被人体所接受,并能够补充相应营养。

The contents of water,soluble sugar,protein and heavy metals(cadmium,lead,mercury)in rice with selenium enrichment in Ankang city were determined by the corresponding method.To study whether the presence of selenium in Se-enriched rice can cause the decrease of nutrient composition or the increase of heavy metal content in rice.The results showed that the nutrient water content of Se-enriched rice was 8.047~14.055 g/100 g,soluble sugar 6.09~9.39 mg/g,protein 7.714~9.225 g/100 g,mercury 0.0137~0.0172 mg/kg,lead 0.089~0.162 mg/kg,cadmium 0.074~0.171 mg/kg,all in line with the national standard.Se-enriched rice can be accepted by the human body,and can supplement the corresponding nutrition.
