How does PurePulse work?

Fine-tuning safe, fresh juice to perfection

Preserving all the fresh goodness in juice while extending its shelf life…it almost sounds too good to be true! And yet PurePulse is a mature technology that has already earned its stripes through several practical applications; the technology has been used successfully for many years in the medical sector, for instance.

PurePulse is based on PEF technology, a continuous preservation process in which liquid food products or beverages are heat-treated and pumped through a pulsed electric field in order to kill off bacteria and moulds. By applying a couple of innovative techniques, PurePulse has fine-tuned PEF to perfection. As a result, you not only achieve the same level of food safety while using less energy and heating, but you also preserve even more of the goodness in your fresh juices.
