Protease enzymes are added to a milky colloidal suspension of egg albumen. As the protease enzymes digest the suspended particles of proteins, the mixture becomes more transparent. The absorbance changes in the reaction mixture are followed with a col

The principle of this assay is to mix an extract of fruit (or vegetable) with a viscous solution of polygalacturonic acid, and then note the decrease in viscosity due to its breakdown by the enzyme.
