PROBLEM TO BE SOLVED: To provide an acidic oil-in-water type emulsified food containing a large amount of minute bubbles stably and inhibiting a sour taste derived from vinegar.SOLUTION: A bubble-containing acidic oil-in-water type emulsified food has 30 Pa s or more of a viscosity after deairing and contains 15-150 bubbles with a diameter of 50 μm or less per 80×10-12m3 when at least 7 days pass after producing. The bubble-containing acidic oil-in-water type emulsified food is produced by finely emulsifying a bubble-containing roughly emulsified product with an emulsifier applied with back pressure.COPYRIGHT: (C)2012,JPO&INPIT【課題】微小な気泡を多量かつ安定的に含有し、食酢由来の酸味が抑制された酸性水中油型乳化食品を得る。【解決手段】気泡入り酸性水中油型乳化食品が、脱気後の粘度が30Pa・s以上であり、製造後少なくとも7日間経過時に、直径50μm以下の気泡を80×10-12m3 当たり15~150個含有する。この気泡入り酸性水中油型乳化食品は、気泡入り粗乳化物を、背圧をかけた乳化機で精乳化することにより製造できる。【選択図】なし
