Determination of pectinase activity
WebBased on the incubation period at 37°C for 3 days, the specific pectinase activity was calculated as 62.18 U/mg for supernatant, 217.44 U/mg for ethanol precipitation, and 41.69 U/mg for ammonium sulphate precipitation. The maximum yield of pectinase was acquired by ethanol precipitation. 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 ).
