Abstract
The reaction of olive oil and glycerol over immobilized lipases was studied. For oil samples with free fatty acid (FFA) contents larger than 2%, FFA esterification and glycerolysis took place simultaneously, but the esterification reaction was faster than glycerolysis. Similar product distributions were obtained for glycerol/oil mole ratios of 3:1 and 6:1. Therefore, an excess of glycerol does not result in a significant increase in monoglyceride yield within the experimental range tested. The main reaction product at 80°C was diglyceride. No increase in monoglyceride yield was observed by lowering the reaction temperature to 10°C.
