Özet

Glycerolysis of palm and palm kernel oils were conducted using a commercial 1,3-specific lipase from Humicola lanuginosa (trade name: SP 398) as catalyst (500 units lipase g(-1) oil) at 40 degrees C and oil:glycerol (1:2 mol mol(-1)) in a solvent-free system. After 24 h, the glycerolysis products of palm and palm kernel oils consisted of 23% triacylglycerols, 18% monoacylglycerols, 38% diacylglycerols and 18% triacylglycerols, 31% monoacylglycerols, 42% diacylglycerols, respectively. The monoacylglycerol fraction of the glycerolysis product of palm oil was enriched in oleic acid. Palmitic acid content of the monoacylglycerol fraction of the same product was less than that of the original oil. Under the same conditions, monacylglycerol fraction of the palm kernel oil glycerolysis product was enriched in palmitic, stearic and oleic acids.
