Determination of pectinase activity
WebPectinase, due to the degradation capacity of pectic substances and, consequently, the improvement of characteristics, such as viscosity, turbidity, and color, is an enzyme widely used in the manufacture of juices, including in the clarification process (Ribeiro et al., 2010; Ortega et al., 2004; Sharma et al., 2024 ). WebMay 24, 2024 · However, pectinase activity was not completely lost even if the temperature increased to 50 °C. Although the maximum pectinase activity was 7.76 ± 56 µmol/ml/min of glucose released at 35 °C, pectinase activities above the optimal temperature were frequently higher than those below the optimal temperature [Table 6].
