Biscuit extrudable at negative temperatures, process for its preparation and use thereof in composite frozen confectionery products

摘要

The reconstituted biscuit material, which can be extruded at negative temperatures, is formed by fragments of frozen baked biscuit or a soft dough iced as a dispersion forming an expanding meringue. The dispersion also contains an expanding protein of egg white or dairy substitute and carbohydrates, frozen at a temperature of -3 degrees C to -8 degrees C. The mixture expands by 80-150%. The completed pastry has a biscuit core covered by a meringue icing.
