High-pressure processing and thermal pasteurization
How high-pressure treatment in sealed packages differs from heating liquid in pipes and heat exchangers.
High-pressure processing needs a package that can handle the pressure cycle. Thermal pasteurization needs the right equipment to heat the product, hold it at temperature and cool it.
Safety, quality and shelf life depend on the recipe, the microorganisms of concern, the validated process and the intended distribution conditions. Sample comparisons inform process design, and commercial conditions need their own validation.
