Solvent-free glycerolysis of sunflower oil catalyzed with lipase D "Amano" 100 gave the highest partial acylglycerols content at 40 degrees C using an oil : glycerol molar ratio of 1:2 and 500 Units lipase/g oil. After 6 h, the partial acylglycerols content of the reaction mixture was 53% (w/w). Glycerolysis of anchovy oil catalyzed under the same conditions gave a partial acylglycerols content of 47% (w/w) after 24 h.
