Figure 3. In mango juice, there was a 13.34% difference in yield from control to crude pectinase and a 23.33% difference in juice output between crude pectinase and purified pectinase. One unit of pectinase activities was defined as the amount of glucose released in the term of mol of reducing sugar per ml per minute under Standard assay conditions [43, 57].
