PROBLEM TO BE SOLVED: To prepare an oil and fat composition prevented from bubbling in fry cooking, excellent in cooking workability, having a long life in fry cooking and useful as general-purpose cooking oil by making the composition include a triglyceride as a principal ingredient, and a specific sucrose fatty acid ester in a specific content. SOLUTION: This oil and fat composition is prepared by including a triglyceride as a principal ingredient and 0.05-15 wt.% sucrose fatty acid ester having an average substitution degree of 3-7 and containing >=85 wt.% polyester with the polymerization degree of >=3 in the whole sucrose fatty acid ester. The aliphatic carboxylic acid constituting the sucrose fatty acid ester is preferably a 2-22C fatty acid and an organic acid (e.g. stearic acid or the like). The ester preferably is prepared by steam distillation under reduced pressure at a temp. of >=140 deg.C and preferably has an acid number of <=1. Rape-seed oil or the like is used as a glyceride mainly comprising the triglyceride. |
