PROCESS FOR MANUFACTURE OF EXPANDED FOODSTUFFS

摘要

In a process for the manufacture of expanded foodstuffs, the paste issues from the nozzle of an extruder and the extrudate is subjected to the after-treatment in a hot medium. At the outlet of the nozzle, the extrudate is maintained at a temperature approximately equal to the temperature at which the paste leaves the nozzle and the after-treatment is applied immediately after extrusion. In particular, the paste can be extruded directly into hot oil or fat. As the extrudate is not cooled, in particular by evaporation of water, after extrusion, it can dilate more during after-treatment, and the foodstuffs obtained have a texture identical to that of foodstuffs which have been subjected to a drying process after extrusion and before treatment in a hot medium.
