PROBLEM TO BE SOLVED: To provide a foamable oil-in-water type emulsion being a low trans acid type oil-in-water type emulsion, having long term emulsion stability, e.g., in which the increase of viscosity after three months of refrigeration storage after production is suppressed, excellent in workability, foamability and appearance upon whipping, and excellent in shape retainability, water separation resistance, nappe and drawing workability, and a method for producing the same.SOLUTION: Using an oil composition for a foamable oil-in-water type emulsion containing 50 to 90 wt.% of ester exchange oil of 30 to 70 wt.% palm-based fat and 30 to 70 wt.% of laurin based fat, 10 to 50 wt.% of palm core curing oil having a rising melting point of 34 to 40°C and 0.01 to 0.5 wt.% of one or more kinds of emulsions selected from sucrose fatty acid ester and polyglyceryl fatty acid ester including 16 to 22 saturated fatty acid and having an HLB of 4.5 or lower as the main fatty acid, the foamable oil-in-water type emulsion is obtained.SELECTED DRAWING: NoneCOPYRIGHT: (C)2017,JPO&INPIT【課題】低トランス酸型の水中油型乳化物であって、長期乳化安定性、例えば製造後冷蔵保管3カ月後の粘度上昇を抑制し、ホイップする際の作業性、起泡性、外観に優れ、保形性、離水耐性、ナッペ及び絞り作業性に優れた起泡性水中油型乳化物及びその製造方法を課題とする。【解決手段】パーム系油脂30~70重量%とラウリン系油脂30~70重量%のエステル交換油脂50~90重量%及び上昇融点34~40℃のパーム核硬化油10~50重量%及び主要脂肪酸として炭素数16~22の飽和脂肪酸を含有するHLB4.5以下のショ糖脂肪酸エステルまたはポリグリセリン脂肪酸エステルから選択される乳化剤1種以上を0.01~0.5重量%を含有する起泡性水中油型乳化物用油脂組成物を使用して、起泡性水中油型乳化物を得る。【選択図】なし
