METHOD AND APPARATUS FOR THE INACTIVATION OF MICROORGANISMS IN LIQUID FOOD AND FEED PRODUCTS

摘要

The present invention is related to a method for inactivating biological contaminants in liquid high fat and/or protein containing food or feed products, comprising the steps of: Providing a reactor vessel (3) arranged to hold liquid or gaseous substances under high pressure, Introducing carbon dioxide e.g. by using high pressure pump (2), in said reactor (3) until a final pressure of between 20 to 200 bar is achieved at a predetermined temperature between 20 and 100°C,. Introducing e.g. by high pressure pump (8), an amount between 20 and 85 % of the total reactor volume of liquid containing biological contaminants to be inactivated in said reactor (3). Optionally introducing an additional amount of carbon dioxide in said reactor to attain a final pressure of between 45 and 350 bar at said predetermined temperature,. Holding said final pressure and predetermined temperature for a predetermined time while stimulating mass transport in said liquid, and. Collecting the inactivated liquid.
