摘要： A process for enzymatically producing, from a vegetable oil deodorizer distillate, a dietary sterol fatty acid ester superior in flavor qualities (e.g., color, odor and taste) and safety and containing no or little trans fatty acids, wherein the conditions for treatment of the starting material, synthetic reaction and subsequent purification are controlled so that the sterol fatty acid ester becomes applicable as a daily food material, a health food material or a pharmaceutical material. In the process, fatty acid esters, e.g., triacylglycerol, in the vegetable oil deodorizer distillate are previously degraded by hydrolysis with a chemical catalyst, fatty acids produced in the hydrolysis are removed by molecular distillation to give a sterol-containing fraction. The sterol-containing fraction is added with any fat and oil primarily comprising triacylglycerol. The mixture is used as the starting material, and the synthetic reaction is performed under strictly controlled conditions using a lipolytic enzyme. The resulting product undergoes several steps of purification process to provide qualities suitable for a food material.
