A novel method for the determination of pectinesterase
inhibitor in banana.
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.

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  and it is a biochemical process involving the hydrolysis of pectin and starch by enzymes such as hydrolases, pectinesterase
, and polygalacturonase .
