HPP is a unique, non-thermal process that kills pathogenic bacteria (listeria, salmonella, E. coli) and spoilage organisms (yeast, mold) through high-pressure, water-based technology. It is a USDA/FSIS and FDA-approved, 100% natural process, and is allowed for use on organic and natural products. It uses pure cold water, and up to 87,000 psi (6,000 bar) to inactivate pathogens and dramatically extend shelf life. No chemicals. No heat. No additives.
