< Topic >Without rising product cost, the case which does not add either special equipment and also, the whip it does there are times when foam characteristic oil-in-water emulsification ones where milk flavor improves are offered.SolutionsGradation of the emulsion of the guttulate which is dispersed in water phase oil and fat amount 15 - 49 weight %, non fat milk solid amount 2 - 15 weight %, and in oil-in-water emulsification ones which include the water, is displayed with the next formula, Relative Span Factor (R.S.F): R.S.F= (D90 D10) it is /D50 1.6, foam characteristic oil-in-water emulsification ones which feature that at the same time 2 D50 1 is filled up.(However, as for D90 volume % accumulation 90 from small particle side of accumulation gradation, as for D10 volume % accumulation 10, as for D50 median diameter is displayed.)< Selective figure >It is not【課題】製品コストを上昇させずに、特別な設備も付加せずとも、ホイップした際の乳風味が向上した起泡性水中油型乳化物を提供することにある。【解決手段】油脂分15~49重量%、無脂乳固形分2~15重量%、及び水を含む水中油型乳化物において、水相中に分散する油滴のエマルションの粒度分布が次式で表される、Relative Span Factor(R.S.F):R.S.F=(D90-D10)/D50≧1.6であり、かつ2≧D50≧1を満たすことを特徴とする起泡性水中油型乳化物。(ただし、D90は累積粒度分布の小粒子側からの累積90体積%、D10は累積10体積%、D50はメジアン径を表す。)【選択図】なし
