  • Effects of extrusion temperature and feed

    2004-6-1 · Extrusion temperature appeared to have little effect on the product L * and a * values when low CF content blends were used. On the other hand, when the CF content of the initial blend was increased, the extrusion temperature increase caused the product browning (Fig. 4(a) and (b)). This fact could be ascribed to CF's high reducing sugars ...
