| Popis: | The effects of reaction parameters such as substrate mole ratio, reaction temperature, enzyme load, water content and reaction time were studied in a model enzymatic acidolysis system. Palmitic and stearic acids were incorporated into triolein (OOO) under the catalysis of sn-1,3 specific lipase to produce the three major triacylglycerols (TAGs) in cocoa butter (CB), namely, 1,3-dipalmitoyl-2-oleoyl--glycerol (POP), 1(3)-palmitoyl-3(1)-stearoyl-2-oleoyl-glycerol (POS) and 1,3distearoyl-2-oleoyl-glycerol (SOS). TAG contents of the reaction products were analyzed by High Performance Liquid Chromatograph (HPLC).The best results (15.2% POP, 30.4% POS, 15.2 % SOS) were obtained at 1:3:3 (OOO:palmitic acid:stearic acid) substrate mole ratio and reaction parameters: time 10 h, temperature 45 oC, enzyme load 20 %, water content 5 %. The results obtained in this model system might be used for the optimization and application of lipase catalyzed acidolysis reactions in natural systems to produce cocoa butter equivalents (CBEs). |
