Abstract: The Hunan lotus was extruded by DS32 Twin-Screw Extruder under different conditions of processes.The changes of the gelafinization degree and the samples density were studied under the different material moisture contents,barrel temperatures and screw speeds respectively.The conclusion is that the gelatinization degree and the density of the extrudants are changed evidently by changing the moisture contents and the screw speeds.

Key words: lotus, extruder cooking, degree of gelatinization, density
