Hardly a day goes by without manufacturers recalling food tainted by impurities. Even dry foods, generally thought to be safe because they lack the water pathogens needed to thrive, are often pulled from store shelves. Harmful microorganisms, such as salmonella, can colonize these foods during processing. Almonds, a popular treat around Christmastime, are one of the mo-re susceptible foods. Now researchers at the Fraunhofer Institute for Environment, Safety, and Energy Technology UMSICHT have developed a new process to kill off germs that befall almonds and nuts: using compressed carbon dioxide to decontaminate food.
