【摘要】 [目的]研究稻米淘洗次数与微量元素含量关系,评价大米清洗过程矿物成分损失情况。[方法]根据稻米的淘洗过程,测定不同淘洗次数下大米的各种营养元素含量。[结果]试验得出,各种营养成分在大米中不是均匀分布的,在淘洗过程中,营养成分将不同程度地流失,且淘洗次数越多,损失越大。[结论]大米在淘洗过程中各种营养元素均有不同程度损失,因此改进大米的加工过程,生产和食用清洁米,对于有效保留大米中营养元素具有重要意义。更多还原

【Abstract】 [Objective] To study on the relationship between rice elutriation times and mineral element contents,evaluate loss of mineral components during elutriation. [Method] The content of element was determined in different elutriation degree. [Result] The result shows that with the more times to elutriate,the more to lose. [Conclusion] Various nutrients were lost in washing process. So improvement of rice processing,production and consumption of clean rice has significance on effectively retaining nutrient elements in rice.更多还原
