Compared to an untreated control, polygalacturonase-based enzymatic puree maceration helped retain pigment levels, but was less effective than
pectinesterase. Color and antioxidant activity were independent of both enzymatic treatments.

pectinesterase synthesis by aggregated mycelium of Aspergillus niger in dependence on the carbon source," Biotechnology Letters, Vol.11, pp.255-58.
The enzymes involved in the breakdown of pectin include pectate lyase, polygalacturonase and
pectinesterase. Olano-Martin et al.
Production of polygalacturonase and
pectinesterase was induced by sodium polypectate, pectin and lactose.
Softening of fruits is due to deterioration in the cell wall composition [33] and it is a biochemical process involving the hydrolysis of pectin and starch by enzymes such as hydrolases,
pectinesterase, and polygalacturonase [34].
