Monoacylglycerols (MAG) and diacylglycerols (DAG) are emulsifiers widely used in food and cosmetic industries. Typical industrial processes for MAG and DAG production consist of the catalytic glycerolysis of triacylglycerols at high temperatures (>200°C). However, the inorganic catalyst and the high temperature contribute to the formation of a product often dark and with unpleasant smell. The goal of this work is the use of enzymatic glycerolysis to improve product aspect and quality, increase selectivity and decrease energy consumption. This reaction produces a mixture of approximately 20% of MAG and 50% of DAG. In order to evaluate the effects of reaction parameters in the MAG and DAG content after the enzymatic glycerolysis reactions of refined sunflower oil a 23 experimental design was employed. A surface response analysis was used to optimize this process.
