As shown three different fruits [apple, lemon, and mango] were subjected to crude and purified pectinase by taking water as control, the maximum clarity of juice was obtained was 95.82% of transmittance for lemon fruit. This can be tested by transferring a pure sample of bacteria from the culture to a sterile tube containing a mixture of urea agar broth and phenol red. 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].

Pectinase has a wide range of applications, which has increased global demand. The efficiency of Pectinolytic enzymes in fruit juice clarity is, however, reliant on the amount of pectin and pectinases available in the substrate, resulting in better juice extraction and clarification [14, 24]. 2022;72(1):15. 2014 Apr.
