Abstract
Frozen aerated compositions are prepared by introducing an unfrozen composition suitable for being frozen for preparing a frozen aerated composition into the barrel of an extrusion apparatus containing a single screw and rotating the screw for transporting the composition through the apparatus to and then through an extrusion exit die and for during transport of the composition through the extrusion apparatus, mixing, shearing and compressing the composition. Additionally during the transport of the composition through the apparatus, the composition is cooled and air is injected into composition to obtain from the die a compressed, aerated, cooled composition which has a temperature of equal to or lower than -8.degree. C.
