However, the most important progress in the field of food extrusion has been the development of extrusion cooking since the 1950s. Extrusion cooking can be defined as a thermomechanical process in which heat transfer, mass transfer, pressure changes and shear combine to produce effects such as cooking, sterilization, drying, melting, cooling, texturizing, conveying, puffing, mixing, kneading, refining, freezing, forming, etc {. Is éard atá i gceist le cócaireán easbhrúite ná caidéal, malartóir teasa agus imoibreoir ardbhrú agus ardteochta leanúnach, iad uile le chéile i ngléas amháin .
