The present invention relates to a method for producing protein-containing foamed food products, comprising the steps: metering raw materials into an extruder, wherein at least one raw material is a protein, mixing the raw materials into the extruder to produce a mixture, extruding the mixture to produce an extrudate, and leading the extrudate out of the extruder through a cooling die with cooling of the extrudate to a temperature of less than 100° C., wherein pores are formed in a controlled manner in the extruder, by providing a gas, by introducing the gas into the extruder or by forming the gas based on a reaction of a gas-forming compound added as a raw material with a gas-releasing compound added as a raw material.

Method for the production of protein-containing foods

A cooling tool () for a food or an animal feed extruder (E), the cooling tool has: an inlet end () at which extrudate () can be led into the cooling tool (); an outlet end () where the cooled extrudate can be discharged; an extrudate flow channel () extending from the inlet end to the outlet end; and at least one coolant flow channel (') connected to the extrudate flow channel in a heat-transmitting manner. In a cross section (X-X) along the primary flow direction (), the extrudate flow channel is substantially formed as a ring section; and the outer wall () of the extrudate flow channel () is formed at least from first and second segments (). The first and second segments are connected to each other by mechanical connection elements (). The cooling tool is suitable for wet texturing of food and animal feed.
