辐照降解魔芋葡甘聚糖产物的制备及结构表征
Preparation and Structural Characterization of Irradiation-Degraded Konjac Glucan Products
摘要
Abstract
In order to promote the efficient utilization of the degradation products of konjac glucomannan(KGM),this research studied the effects of irradiation on the degradation products of KGM.The changes of molecular weight,intrinsic viscosity,soluble sugar content,electrochemical properties,appearance,color,microstructure,chemical structure,and crystal structure of(KGM were investigated under different irradiation doses.The results showed that there was no change in the main chain structure and weakened crystalline region of KGM irradiated degradation products compared with the unirradiated KGM.With irradiation dose increased,the KGM irradiated degradation products showed a decreased molecular mass from 894.6 to 4.70 kDa,as well as a decreasing trend of intrinsic viscosity and total soluble sugar content.SEM results showed that the irradiated degradation products of KGM were flaky and porous,and the Zeta potential was significantly changed.This work provided a strategy about the degradation and modification of KGM by irradiation for the efficient utilization of resources.关键词
