Fecha de publicación: -- Fuente: WIPO "tomato" The present disclosure relates generally to apparatuses for reactive processing of a composition, particularly for producing certain comestible compositions. In some embodiments, the apparatuses are extrusion apparatuses. In general, such extrusion apparatuses are suitable for making reaction flavor compositions, such that the extruded material is heated during the extrusion process to induce flavor formation, for example, via a Maillard reaction or other browning reactions. In certain embodiments disclosed herein, the extrusion apparatus is modified to allow for more efficient degassing and cooling, as well as more efficient post-reaction processing of the extruded material. In some other embodiments, the disclosure provides apparatuses that include two or more kneader reactors arranged serially and their use for producing certain comestible compositions.
