Evaluación del óxido de titanio para evitar la formación de biofilms

Inasmuch as the presence of biofilms in the Food Industry is one of the most important problems, both technological and Public Health, it is important to avoid the development of these biofilms in food contact surfaces or, if they are already established, it is important to destroy them. Various materials with biocides have been developed, but it is still necessary to prove its safety. One variant that could achieve good results is the use of TiO2, which under UV irradiation and a specific humidity, can generate a photocatalytic reaction that can attack and break the outer membrane of the bacterial cell, being able to inactivate free microorganisms or attached in biofilms.
