Parameter optimization for the enzymatic hydrolysis of sunflower oil in high-pressure reactorsPrimožič, Mateja, 1975- ; Leitgeb, Maja ; Knez, ŽeljkoThis study is concerned with the hydrolysis of sunflower oil in the presence of lipase preparation Lipolase 100T (Aspergillus niger lipase). Supercritical carbon dioxide was used as a solvent for ... this reaction. In a high-pressure stirred tank reactor operated in a batch mode, the effects of various process parameters (temperature, pressure, enzyme-substrate ratio, pH, and oil-buffer ratio) were investigated to determine the optimal reaction rate and conversionfor the hydrolysis process. The optimal concentration of lipase was 0.0714 g/mL of CO2-free reaction mixture, and the highest conversions of oleic acid (0.193 g/g of oil phase) and linoleic acid (0.586 g/g of oil phase) were obtained at 50°C, 200 bar, pH = 7, and an oil/buffer ratio of 1/1 (w/w).Source: Journal of the American Oil Chemists' Society. - ISSN 0003-021X (Vol. 80, no. 7, 2003, str. 643-646)Type of material - article, component partPublish date - 2003Language - englishCOBISS.SI-ID - 8216342
