DELPHOS, Ohio — Hydrofresh HPP, an affiliate of Keller Logistics Group, is constructing a $10 million pasteurization plant slated for opening in April. The plant will be located in Delphos (near Toledo) and will use innovative high-pressure processing technology.

Unlike the traditional pasteurization method that uses heat prior to packaging to eliminate micro bacteria that are present in food, Hydrofresh HPP will use a natural, cold pasteurization technique by which products already sealed in their final packaging are placed in a vessel and subjected to a high level of isostatic water pressure, up to 87,000 psi.

“This is exciting, state-of-the-art technology that will aid in the growth of locally produced natural and organic products,” said Hydrofresh HPP President Don Klausing. “This will be the only HPP tolling facility in this part of the country, and we are already experiencing tremendous demand for our services.”

The process produces a 5-log reduction in salmonella, E. coli and listeria while preserving the color, texture, nutrients and flavor of the product. Shelf life is also extended because the bacteria that cause spoilage is destroyed.

HPP equipment is being installed in the 36,000 square-foot refrigerated warehouse for storage and production. The plant will initially run one shift with one machine and approximately 12 employees. Upon completion the plant will be able to process 60 million pounds of product per year.

Products that use this technology include refrigerated dips, natural lunch meats, cold-pressed juices, deli salads and various other natural products.
