Abstract: There are numerous, about Calcium content in white rice. Calcium content of white rice are distributed thus, somewhat due to the differences of soil condition, fertilizer, kind, rice-hackle, mix up. But I think that the general situation of the content exist surely.Calcium is analysed by the gravimetric method.There are two-, Calcium gravimetric methods. The one is washing Ca(COO)2-H2O ppt. by 0.1% (NH4)2(COO)2, and the other is washing the ppt. by hot water.So, investigated the dissolving Ca(COO)2-H2O ppt. by hot water. The results are as follows:(1) In the Calcium gravimetric analysis of randomized 17 samples, Calcium contents of the rationed rice are concentrated near 9mg/100g.(2) There are no difference analytically, between two Calcium gravimetric methods.
