Abstract
Lipid modification through the conversion of triacylglycerol (TAG) to partial acylglycerol, namely monoacylglycerol (MAG) and diacylglycerol (DAG), has developed rapidly to obtain structured lipids (SLs) that can be used in various pharmaceutical, food, and cosmetic industries. Glycerolysis of TAG enables high MAG and DAG recovery by optimizing the factors influencing the reaction. This article provides an overview of various studies on the factors that affect glycerolysis, especially the ratio of fat/oil to glycerol used. The oil to glycerol ratio plays a role in determining the progress of TAG conversion and the composition of reaction products. Excess glycerol in the reaction system encourages further glycerolysis reactions due to its reaction with the formed DAG to produce MAG. On the other hand, the reaction leads to the formation of more DAG if the amount of glycerol is limited. The use of an oil to glycerol molar ratio close to 1:5 is recommended to support high MAG synthesis, while a 2:1 ratio is recommended to support more efficient DAG synthesis.

Keywords
