Monoglyceride production via enzymatic glycerolysis of oils in supercritical CO2

摘要

Production of monoglycerides is enhanced by means of enzymatic transesterification of triglycerides with aliphatic alcohols in a medium of supercritical CO2. Aliphatic primary and secondary alcohols of 1 to 8 carbon atoms may be used without support in supercritical CO2 at temperatures compatible for enzymatic transesterifion of tryglycerides. Utilization of these lower reaction temperatures has the benefit of diminishing the production of undesired side products and thus increasing the reaction efficiency with regard to production of the desired monoglycerides.
