Usage of Immobilized Porcine Pancreas Lipase in the Hydrolysis of Roselle (Hibiscus Sabdariffa L.) Seed Oil

This study focused on the comparison among the usage of immobilized porcine pancreas lipase (PPL) on different hydrotalcite carriers (uncalcined and calcined hydrotalcite - like compound Mg /Al) and free lipase as the catalysts to hydrolyze of roselle (Hibiscus sabdariffa L.) seed oil. The reaction conditions were investigated including the ratio of oil to buffer, ratio of enzyme to substrate, the temperature of the hydrolysis, pll. The calcined hydrotalcite showed a higher lipase immobilization yield and a better reusability than the uncalcined hydrotalcite (87.15% and 86.78%, respectively).
