ProduSafe QX antimicrobial nanocoating proven effective by TNO and a new nanocoating containing titanium dioxide (TiO2) that guarantees clean and safe tanks, silos, spray dryers and food production surfaces.
Using what is known as the ‘chicken filet test’, Dutch research institute TNO has proven that the active ingredient in ProduSafe QX does not migrate into food products. These test results pave the way for the manufacturer to apply for ‘food-grade’ status at EFSA.
ProduSafe QX is suitable for any company looking to ensure optimum hygiene and reduce the risk of microbial contamination, as are most companies in the food and beverage industry. The coating consists of TiO2 nanoparticles in an aqueous suspension. Under the influence of UV light, titanium dioxide releases oxygen free radicals that eliminate bacteria, viruses and fungi.
The antimicrobial coating proved effective on the 11 microorganisms TNO tested for. Fungal spores were resistant to the coating’s antimicrobial effect, but after hatching the fungi were killed by the coating. Cleaning did not affect the coating’s effectiveness.
The TiO2 particles are so small they permanently adhere to and become part of the surface’s crystalline structure. Because the particles are so small, the active surface is large. The coating makes the food contact surface highly hydrophilic, so the water forms a smooth film on the surface. Organic material is broken down from the surface up. Hence, it has difficulty attaching to the surface and is easy to rinse off. The coating disappears only through wear and tear………………………..
