PROTEASE ENZYMES

Main Application Effects of Proteases

Proteases catalyse the hydrolysis of protein soils into smaller fragments, i.e. peptides or amino acids. The fragments go into solution or are dispersed by surfactants from the detergent.

Proteases are used to remove protein-rich soils such as dairy products, cocoa, blood and grass. These relatively common soils are strongly coloured, which means that the effect of proteases is easily recognised by consumers.

In automatic dishwashing, proteases are used to remove stubborn protein soils such as egg, milk and minced meat.

A small but fairly widespread use of proteases is in the cleaning of endoscopes, which do not tolerate conventional cleaning. Gentle cleaning of ultrafiltration membranes is another soft cleaning application for proteases.
