摘要
采用贝利粉碎机对木薯淀粉进行机械活化,研究了逆研磨对木薯淀粉理化性质的影响。结果表明,逆研磨后,颗粒粒径变化很小,团聚颗粒更多,结晶结构无变化,溶解度增大,膨胀度、表观粘度减小,透明度变化不大,剪切稀化程度降低,Brabender黏度曲线由B型变为D型。
Cassava starch was mechanically activated by beili pulverizer and the effect of counter-milling on physicochemical properties of cassava starch were also investigated in this paper. The results showed there was little change in granule size,transparency and crystalline structure,but with more granules gathered,solubility increasing while swelling power,at the same time the apparent viscosity and shear thinning all reduce as well as the viscosity patterns of brabender viscosity curves change from Type B to Type D after counter-milling.
