ProduSafe QX antimicrobial nanocoating proven effective by TNO

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………………………..

Inspection platform for tanks, silo’s and spray dryers

This month already the 3th inspection bridge was delivered which was developed out of the partnership between Altrex and ProduSafe and used for crack testing of two huge spray dryers at one of the biggest producers of baby food in the world.

This installation makes inspections and entrance of silos/tanks and spray dryers very easy and comfortable because no scaffolding is needed anymore. It safes a lot of costs and reduces downtime to a minimum to achieve less downtime of production.

The inspection platform guarantees safe working at height. The system meets International and European regulations as EN 1808 and the Machinery Directive. TÜV, the world renowned Notified Body, has approved the system and is unique in the world.

 Millions are lost annually on products that do not meet the quality requirements. And what about products that inadvertently get onto the market. The consequences of this can be enormous. The preventive inspection of production installations prevents these problems.

ProduSafe arranges this by:

  • Periodically checking the installations for possible defects
  • Preventive inspection of high-risk locations (related to contamination or infection
