Question

Why is the enzyme pectinase added during the manufacture of fruit juices?

Answer 1

The enzymes used are designed to break down cells walls and release the liquids and sugars which make up the fruit. Pectinases, amylases and cellulases all break down different structures of the fruit cells and so affect the extraction process in different ways.

Answer 2

The enzyme pectinase speeds up the breakdown of pectin in fruits, producing more juices
