This invention to be useful as the additive for the food, which is used with purpose such as flowability improvement, prevention of consolidation, decrease and food impression improvement of hygroscopicity being the metal soap where the influence for the food is small, the carbon count be the metal soap which is the fatty acid calcium or fatty acid magnesium of 6 which is obtained by double amount solution - 24, reacting the basic chemical compound of 1 value in ratio under 0.9 - 1 mols 2 mass of the said metal soap % the metal soap, and the carbon count vis-a-vis fatty acid 1 mol 6 where for food addition pH of water dispersed liquid is under 6 - 7 - 24, the fatty acidThe basic chemical compound salt profit, this and production method of the metal soap for food addition which reacts with the calcium salt or the magnesium salt in water medium is offered.本発明は、流動性改良、固結防止、吸湿性の低下、食感改善などの目的で使用する食品用添加物として有用であり、食品に対する影響の小さい金属石鹸であって、複分解法により得られた炭素数6~24の脂肪酸カルシウムまたは脂肪酸マグネシウムである金属石鹸であり、該金属石鹸の2質量%水分散液のpHが6~7未満である食品添加用金属石鹸、および炭素数6~24の脂肪酸1モルに対して1価の塩基性化合物を0.9~1モル未満の割合で反応させて脂肪酸の塩基性化合物塩を得、これとカルシウム塩またはマグネシウム塩とを水性媒体中で反応させる食品添加用金属石鹸の製造方法を提供する。
