1-Propyl laurate synthesis should not be used as standard reaction test of immobilized enzymes in microemulsion-based organogels (MBGs) prepared using lecithin/1-propanol as surfactant when extremely active enzymes with high load are used. In these cases, an anomalous kinetic reaction constant value is observed over short reaction times. Such an anomalous profile is strongly dependent on the concentration of catalyst in the crude powder and, consequently, is not appreciated when either commercial or low activity lipase samples are employed.
