摘　　要：大米是人体摄入维生素的重要来源。石碾米是稻谷经石碾碾磨得到的大米,相较精米在加工过程中保存了部分糙米的外层组织。为了比较石碾米与精米的营养成分差异,采用国家标准方法分析了石碾米和精米中的VB1、VB2、VB6和VE含量。结果表明,石碾米中的VB1、VB2和VE含量显著高于精米,且石碾米中的VE为精米中的16.7倍,说明石碾米的营养价值较高。Rice is an important source of vitamins for human.Stone milled rice is the rice milled by stone,which preserved the outer parts of brown rice compared with polished rice.The contents of vitamin B1,B2,B6 and VE in stone milled rice and polished rice were systematically studied with national standard methods.The results showed that the contents of vitamin B1,B2 and VE in stone milled rice were significantly higher than those of polished rice.Especially,the content of VE in stone milled rice was as high as 16.7 folds compared with the polished rice.It is showed that the stone milled rice has high nutritional value.
