A method of preparing a particulate frozen food product, especially frozen cheese granules or shreds, in which moisture is added to the particulate food product prior to or at the time of freezing, or following freezing, so that some or all of the food particles have a coating of ice on the exterior. The method has particular application to the preparation of frozen grated mozzarella cheese for use in cooking of food products such as pizzas. A frozen food product consists of particles each having a core of mozzarella cheese coated with ice. Cheese particles are transferred via conveyor (305) into a chilled rotating drum and is sprayed with liquid nitrogen from nozzle (309) and the chilled cheese is then exposed to a fine water spray from nozzle (310) so that the cheese particles are coated with ice before they impact the rotating tumbler (301) which has an octogonal interior and two boards (302,307) which help to ensure that the tumbling product is mixed. |
