PROBLEM TO BE SOLVED: To provide a foamable oil-in-water-type emulsified oil and fat composition used at a foaming state by causing the same to co-exist with a gas to be pressed in a pressure-resistant container, expanding the gas by pressure opening, and excellent in foaming agent and artificial flower making properties of a foamed article.SOLUTION: There is provided a foamable oil-in-water-type emulsified oil and fat composition containing hydroxypropyl methylcellulose of 0.05 to 0.5 mass%. There is provided a foamable oil-in-water-type emulsified oil and fat composition preferably having viscosity of 450 to 3000 cP with a B type viscometer at 5°C. There is provided a foamable oil-in-water-type emulsified oil and fat composition preferably containing one or more kinds selected from pectin, arabic gum, carrageenan, curdlan, gellan gum, fermented cellulose, guar gum, xanthan gum, locust bean bum or Na alginate.SELECTED DRAWING: NoneCOPYRIGHT: (C)2019,JPO&INPIT【課題】耐圧容器中に被加圧気体と共存させ、圧力開放により気体が膨張し、それに伴い起泡状態とされ使用される起泡性水中油型乳化油脂組成物で、起泡性と起泡物の造花性に優れた起泡性水中油型乳化油脂組成物の提供。【解決手段】ヒドロキシプロピルメチルセルロースを0.05~0.5質量%含有する起泡性水中油型乳化油脂組成物。5℃におけるB型粘度計で、粘度が450~3000cPであることが好ましい、起泡性水中油型乳化油脂組成物。好ましくは、ペクチン、アラビアゴム、カラギーナン、カードラン、ジェランガム、発酵セルロース、グアーガム、キサンタンガム、ローカストビーンガム、又はアルギン酸Naから選ばれた1種以上を含有する起泡性水中油型乳化油脂組成物。【選択図】なし
