Summary:A process for preparing pectinase includes such steps as selectively culturing Aspergillus niger seed and enlarged culturing; preparing culture medium; inoculating Aspergillus niger and uniformly mixing; regulating pH to 3.9-4.5, fermenting at 25-35 deg.C for 72-84 hr, immersing in water, pulverizing, centrifugal separation of dregs, then fine filtering to remove macromolecular impurities, and membrane filtering to remove micromolecular impourities. It features low cost.
