Blaise Pascal, a French scientist of the 17th century, researched the effects of pressure on fluids. His research lead him to a method called high pressure processing (HPP) which uses pressure—rather than heat, chemicals, or irradiation—to preserve and sanitize food. Although discovered long ago, HPP has become quite a big deal in the food industry as of late.
In a Food Safety News article called “Putting on the Pressure: ‘No Heat’ Way to Zap Pathogens,” Cookson Beecher explains that more than four centuries after Pascal’s scientific advance, HPP is being utilized by companies like Maple Lodge Farms, Starbucks, Cargill, and Hormel to kill harmful pathogens like E.coli, Listeria, and Salmonella. And the good news is that this process does not change the nutritional quality or the taste of the treated food.
Many people in the food safety world regard HPP as a “natural option for food safety” and a “technological breakthrough.” V.M. Balasubramaniam, an HPP researcher, says that Cargill’s use of HPP is “the most promising food-safety innovation in recent years” and will become a “key player in food safety.” Companies are learning that HPP, though a more expensive way of preserving and sanitizing food, is worth the extra money to their consumers who are becoming increasingly aware of food safety issues.
