小麦麸皮膳食纤维挤压加工工艺研究
Research on Extrusion Processing of Wheat Bran Dietary Fiber
摘要
Abstract
Wheat bran dietary fiber as raw material, twin-screw extruder extrusion process was employed to enhance the soluble dietary fiber content in wheat bran dietary fiber. The effect of extrusion temperature, moisture content of materials and screw speed on the content of soluble dietary fiber in the raw material were investigated . The results suggested that; wheat bran moisture content 20% , extrusion temperature 170 ℃ and the host speed 185 r/min, the bran soluble dietary fiber content of raw materials was increased from 3.22% to 10. 14%. HPLC detection, scanning electron microscopy and water holding capacity and swelling force experiments showed that pressure treatment can effectively increase the soluble dietary fiber content, and change the surface structure of wheat bran.关键词
