To figure out how much juice was made from each piece of fruit, Rai et al., [20] used the method. The total phenol content of the sample was determined by comparing it to the Gallic acid standard curve, with the result represented in mg gallic acid equivalent per ml juice sample (mg GAE/ml)[49]. With 10mg of protein concentration, the maximal activity was 47.32 U/mg, suggesting that the protein molecules separated by ammonium mainly contained the enzyme pectinase and that the proportion of protein other than pectinase was higher in the crude form of the enzyme [11, 31, 44].
