Project Abstract

The proposed research focuses on minimizing hazardous waste generation during cleaning in place operations in the dairy processing industry. The study will examine the potential of replacing currently used environmentally significant CIP agents (eg. acid, alkali, phosphate containing detergent and hypochlorite) either partially or entirely with enzymes (proteases and lipases), which are biodegradable and have minimal environmental impact. Several recently developed commercialised enzymes as well as microbial enzymes produced in-house will be tested in terms of their suitability for this purpose by quantitatively monitoring their cleaning efficiency when applied to surfaces (stainless steel and glass) experimentally fouled with milk and milk protein fractions.
