The determination of the mineral contents, in some commercially available tofu by atomic absorption spectrophotometry and flame spectrophotometry was examined. The mineral contents in Kinugoshi and Momen -tofu were compared with the values of the standard table of food composition. It was found that the contents of minerals were higher than the values of the table, except that Ca values was lower. Comparing the mineral contents between the Kinugoshi and Momen -tofu, contents of Na, K, and Mg were higher in the Kinugoshi -tofu, and contents of Fe, Zn, and Ca were higher in the Momen -tofu. This fendency was consistent with the table with the exception of Na.
