Abstract
Described is a method of producing compositions comprising a high concentration of glycerol monoesters. The method entails reacting a mixture of glycerol, a fatty acid source, and water, in the absence of catalysts, at a temperature preferably from about 180° C. to about 300° C., a pressure preferably from about 15 psig to 400 psig, and for a time sufficient to yield an acid value of preferably from about 2.0 to about 7.0 in the mixture, and a hydroxyl value preferably of from about 260 to about 460 in the mixture. The method can be used to make lipid mixtures comprising 90 wt % or more of glycerol monoesters. The method does not require molecular distillation.

A method of producing a composition of matter comprising glycerol monoesters, the method comprising:
- reacting a mixture comprising glycerol, a fatty acid source, and water, and devoid of catalysts, at an elevated temperature and at an elevated pressure wherein the glycerol and the water have increased solubility in the fatty acid source as compared to their respective solubilities at room temperature and atmospheric pressure, for a time sufficient to generate a composition of matter comprising at least about 50 wt % glycerol monoesters.
A method of producing a composition of matter comprising glycerol monoesters, the method comprising:
- reacting a mixture comprising glycerol, a fatty acid source, and water, and devoid of catalysts, at a temperature of from about 180° C. to about 300° C., and a pressure of from about 15 psig to 400 psig, for a time sufficient to yield an acid value of from about 2.0 to about 7.0 in the mixture, and a hydroxyl value of from about 260 to about 460 in the mixture;
- and then
- removing excess glycerol from the mixture, thereby yielding a composition of matter comprising at least about 90 wt % glycerol monoesters.
