Sustainability Patents for Food and Beverage Manufacturers Granted to Radical Waters in Columbia

Radical Waters International Ltd.’s patents granted in Colombia are for Biofilm reduction and flavour residue in beverage processing, and disinfection in food and beverage processing.

Radical Waters expects to have these patents together with the Cleaning in Place and Water Savings patent granted in all other major beverage producing countries where these patents are currently pending.

Patents held by Radical Waters related to food and beverage processing include the three patents granted in Colombia, along with the Cleaning in Place and Water Savings patent currently pending in Colombia.

Some or all of these four individual patents relating to food and beverage processing have previously been granted and are in effect in the United States, China, South Africa and Nigeria and have been approved for granting in Mexico.

Patent Granted: A method of reducing biofilm growth in a beverage processing system

Known for its tough resistance to conventional biocides and the formation of a self-produced matrix of extracellular polymeric substance or slime, Biofilm is a ‘hidden’ biological threat, which can under the right conditions; adhere to less obvious areas and surfaces inside the piping matrix of beverage lines. This biofilm formation can cause product contamination, microbial induced corrosion and can cause reduced heat transfer in cooling or heating water systems.

Electro-chemically Activated Water (ECA) is highly effective against 99, 9999% of microbes as well as in the removal of Biofilm.

Biofilm’s mechanism of adhering to surfaces is based upon the premise of electrostatic interactions between itself and the surface it has contact with.

Radical Waters ECA solutions disrupt the electrostatic interactions between these two surfaces through electron transfer, thereby effectively removing the Biofilm.

In the beverage industry, ECA is particularly effective for the terminal control of superficial microbial biofilm growth with a resultant reduction of recontamination of packaged product. ECA can also be used to reduce and eliminate the biofilm growth in the ingredient water feed stream.

Patent Granted: A method of cleaning or disinfecting at least a portion of a food processing system

This patent relates to the further enhancement of ECA Anolyte solution through the addition of C02, which in turn, as a result of this chemistry, creates an increase in potency.

The use of this enhanced ECA is most beneficial when used in areas containing highly sensitive products.

“Less Anolyte is used which results in further minimisation of concerns, when used in conjunction with high risk, ultra-sensitive products such as bottled water and preservative formulations such as iced coffee, wherein taste, colour and consistency are critical elements of the product’s constitution” says Philip Nel, VP Technical & R&D.

Patent Granted:    A method of transitioning at least a portion of a beverage processing system from processing a first beverage to processing a second beverage.

Some beverage products include a material that is incompatible with a second beverage and a certain amount of that material remains in the processing system after processing the first beverage. The incompatible material can be a substance which imparts a flavour, colour, smell or it can be an alcohol. Beverage producers previously had to resort to hot chemicals to remove these types of incompatible materials.

Radical Waters ECA solutions are extremely favourable in the oxidation and removal of residues associated with flavour, colour or odour carry-over when beverage plants perform product change-overs, without affecting the expected flavour, colour or odour of the subsequent beverage.
