PurePulse Has Pilot Line Available For Risk Analysis

For companies that want to know specific results based on their raw materials and finished products, PurePulse has a pilot line with surrogate pathogens available. The preservation method Pulsed Electric Field (PEF) is officially approved by de U.S. Food and Drug Administration (FDA). Research indicates that inactivation of relevant pathogens is possible, which is an important requirement of the FDA. PurePulse, the new generation of PEF, is hereby recognized as a base technology that meets the rigorous standards in the USA.

PurePulse is a milder variant of the existing first generation PEF technology, and is also called PEF 2.0. This method makes it possible to produce fresh juices and smoothies with a long shelf life, without compromising on the original taste and nutritional value. A new method brings up also questions such as: will harmful pathogens be killed sufficiently and does it meet the requirements of the legislation? The answer is yes.

The legislation on food safety in America and Europe is basically the same. In both cases it is necessary to provide a risk analysis of the raw materials. In addition, the FDA requires for juice preserving methods that they are able to prove a 5-log reduction of pathogens. That means that 99,999 % of the pathogens are inactivated. In case of juices and smoothies, E.coli is often the target pathogen. To prove this, studies are carried out on Pulsed Electric Field with relevant surrogate pathogens, and the results are very positive. PurePulse therefore fully meets the standard requirements of the FDA. This underlines that the method is not a 'novel food' technology, which means that there are also in the EU no obstacles to apply PurePulse in food production.

The company behind PurePulse, Cool Wave Processing, has a pilot line available for producers that want to do a risk analysis of their raw materials with surrogate pathogens. This line is also available for sensory testing and more extensive test programs.
