High Pressure Processing: Pros and Cons

The food industry now uses high pressure processing to increase the shelf life of foods and maintain their nutritional value. This non-thermal preservation technique can successfully inactivate rotting and spoilage-causing bacteria and enzymes without the need for high temperatures during the preservation process. Food is exposed to high pressure, usually in the range of 100 to 600 MPa. High-performance processing keeps food at or slightly above room temperature to prevent heat-sensitive flavors and nutrients from being thermally destroyed during food preparation. This contributes to the preservation of the natural sensory and nutritional properties of the product. Because this process is able to eliminate bacteria and organisms responsible for spoilage, it is a very efficient way to increase the time available to eat foods. Unlike traditional heat-based methods, HPP inactivates harmful microorganisms and enzymes through the application of extreme pressure (100–600 MPa) at low temperatures, thereby reducing thermal degradation. HPP also helps retain bioactive compounds, making it an ideal choice for consumers looking for minimally processed, high-quality foods. This article explores the principles, applications, and benefits of HPP, as well as the challenges and future prospects of its integration into food processing systems.
