Expansion ratio in Lentinus edodes's fiber, carrageenan, flour mixture by Clextral BC 45 extruder: A response surface analysis. J. Y. ZHOU. School of Food Science and Technology, Wuxi University of Light Industry, Wuxi Jiangsu, 214036, P. R. China.
Mixtures of Lentinus edodes's fiber, carrageenan and wheat flour were extruded in a Clextral BC 45 twin screw extruder. The feed supply consisted of different Lentinus edodes's fiber, carrageenan, flour ratios and moisture content. Variable process conditions were barrel temperature and screw speed. We determined the expansion ratio of the extrudate, and quadratic response surfaces were fitted to these responses. Barrel temperature, moisture content and screw speed obviously had greater influence on the expansion ratio than the Lentinus edodes's fiber, carrageenan, flour ratios, the highest expansion ratio occurred at the highest screw speed, highest barrel temperature, lowest moisture content.
