摘要： In a method for the inactivation of microorganisms in liquid foods, a liquid food is mixed with a pressurized, liquefied gas at a pressure which is sufficient to maintain the liquefied gas in the liquid state. The mixture of food and gas is then depressurized to a pressure at which the liquefied gas is vaporized. According to the invention, before or during the depressurization to the second pressure, the mixture is guided through a pipeline and brought up to a flow speed in the pipeline which is sufficient to form cavitations in the liquid food.
