Water plays a critical role in food processing, from cleaning and sanitation to production itself. However, water systems, including loops, reuse circuits and water treatment units are also recognized as high-risk areas for biofilm development, allergen persistence and microbial contamination. These risks are further amplified by the growing pressure to reduce water and energy consumption while maintaining the highest food safety standards.

This presentation explores how enzymatic solutions can contribute to improved food safety by targeting biofilms within water-related systems and food processing environments. Special attention is given to water loops, water reuse strategies and water treatment plants, where conventional chemical approaches often struggle to fully remove biofilm matrices and associated contaminants.

Enzymes offer a targeted and efficient mode of action by degrading specific components of biofilms, including extracellular polymeric substances (EPS), thereby weakening biofilm structure and improving overall cleaning performance. When integrated into cleaning-in-place (CIP) protocols, enzymatic treatments help reduce allergen carry-over risks on equipment surfaces and within water circuits, supporting safer and more controlled production environments.

The presentation will also highlight recent advances in cold-active enzymatic formulations, effective from 20°C, enabling efficient cleaning without the need for high temperatures. These solutions not only reduce energy consumption and operational costs but also support sustainability goals linked to water and energy efficiency. Their biodegradability and compatibility with water reuse strategies make them particularly relevant in the context of modern food safety and environmental regulations.

By combining biofilm control, reduction and low-temperature performance, enzymatic technology represent a powerful and future-oriented approach to food safety management. This talk will provide practical insights into how these solutions can be implemented across food processing applications to support safer, cleaner and more sustainable water and hygiene systems.
