PROBLEM TO BE SOLVED: To provide an acidic oil-in-water emulsified food with suppressed flavor deterioration by light irradiation.SOLUTION: There is provided an acidic oil-in-water emulsified food containing an edible oil and fat containing triglyceride of 25 to 80 mass%, egg yolk of 5 to 20 mass%, 90 mass% or more of free aliphatic acids contained in the acidic oil-in-water emulsified food is saturated aliphatic acid and/or monovalent unsaturated aliphatic acid, linolenic acid is 7 to 25 mass% based on the acidic oil-in-water emulsified food among constituent aliphatic acid in the triglyceride, the free aliphatic acid is 0.03 to 1.5 pts.mass based on 100 pts.mass of the linoleic acid as the constituent aliphatic acid of the triglyceride.SELECTED DRAWING: None【課題】光照射による風味劣化の抑制された酸性水中油型乳化食品の提供。【解決手段】トリグリセリドからなる食用油脂を２５～８０質量％、卵黄を５～２０質量％含有する酸性水中油型乳化物において、前記酸性水中油型乳化物に含有される遊離脂肪酸のうち、９０質量％以上が飽和脂肪酸及び／又は１価の不飽和脂肪酸であり、前記トリグリセリドにおける構成脂肪酸のうち、リノレン酸が酸性水中油型乳化物に対して７～２５質量％であり、前記トリグリセリドの構成脂肪酸であるリノレン酸１００質量部に対して前記遊離脂肪酸が０．０３～１．５質量部である、酸性水中油型乳化食品。【選択図】なし
