In a food processing line, the equipment which is likely to fragment on breakage contains magnetically susceptible particles which are separated from the food by a magnetic separation stage. When the equipment is a starch carrying tray, the molding mix contains 5-50% of magnetic filler, such as magnetite. Reinforcement with glass fiber and jute fiber modifies the compositions for moulding the trays. Molding mixes based on polypropylene and thermosetting resins are described. A processing line using starch trays has a conveyor for food items and a conveyor for the starch in which the food items are molded. Both have magnetic separators.
