摘要

A process includes the transesterification of a fatty acid triglyceride ester with a salt of hydroxycarboxylic acid without making use of organic solvents. The process can carried out with natural oils as starting material and produces a mixture of medium chain mono and diglycerides and medium chain esters of hydroxycarboxylic acid.
