Delphos, OH – Hydrofresh HPP, an affiliate of Keller Logistics Group, is constructing a $10 million pasteurization plant at 1571 Gressel Drive in Delphos that uses innovative high-pressure processing (HPP) technology.
Unlike traditional pasteurization method which uses heat prior to packaging to eliminate micro bacteria that are present in food, Hydrofresh HPP will be using High-Pressure Processing. HPP is a cold pasteurization technique by which products already sealed in their final packaging are introduced into a vessel and subjected to a high level of isostatic pressure, up to 87,000 psi, transmitted by water. This process produces a 5-log reduction in salmonella, e coli, and listeria (bacteria that causes food borne illness) while preserving the color, texture, nutrients, and flavor of the product. Because the food is treated in its final packaging, the chance for recontamination is virtually non-existent.
