PURPOSE: To provide the title composition causing no property changes such as thickening and solidification during its sterilization, distribution and storage, excellent in foamability and whipping performance, useful for aseptic foods, comprising an aqueous phase containing fatty oil, non-fatty milk solid, etc., and a specific emulsifier.

CONSTITUTION: The objective composition comprising an aqueous phase containing (1) pref. 30-50wt.% of fatty oil such as soybean oil and (2) pref. 2-6wt.% of non-fatty milk solid, etc., and also containing such an emulsifier as to contain (A) 0.05-1.0wt.%, based on the fatty oil, of lysophospholipid and (B) 0.8-2.0wt.%, based on the fatty oil, of a polyglycerin fatty acid ester and/or sucrose fatty acid ester, and to be (C) (10:90)-(70:30) in the weight ratio of unsaturated fatty acid ester plus saturated fatty acid ester based on the total of the polyglycerin fatty acid ester and/or sucrose fatty acid ester. The HLB value of the above emulsifier mixture is pref. 8-13.
