Materials and Methods Materials.
SPJ-40 experimental twin-screw extruder: De Ai Food Science & Technology Co., Ltd.
Within a certain range when material feeding rate increased, the filling materials in tube raised too, which leaded to increasing the extrusion and shearing action.
The evenly and smooth surface texture of raw materials was changed into sheets after the extrusion which was beneficial to the flavonoids extraction.
This pretreatment of extrusion process has great effect on the increase of extraction rate of flavonoids which is from the fiber materials.

Recently natural materials are becoming a good alternative for synthetic material as they provide good health to a greener environment.
Due to that, many researchers are interested in natural based materials rather than using synthetic materials.
