Versuchsvorschrift
A mixture of oleic acid (1.5 g=5.32 mmoles), glycerol (0.57 g=6.2 mmoles), water (70 μl) and potato protein extract (100 mg) was stirred at 50° C. and a vacuum (<50 mbar) was applied to the system using an oil pump to remove water from the mixture. For comparison a similar reaction was run without vacuum in a stoppered tube. Samples were taken from the reaction mixtures periodically for analysis by GC. Progress curves for the reactions are given in FIG. 2. In the reaction cariied out under vacuum 4.43 mmoles of MG and 0.10 mmoles of DG were formed after 72 hours. 87% of the oleic acid was converted into acylglycerols. In the comparison reaction after 72 hours 3.51 mmoles of MG and 0.14 mmoles of DG were formed. The final conversion of oleic acid into acylglycerols was 71%.
