Abstract：ABstract:OBjective Tooptimizethedegradationprocessoffenugreekgumandtoobtainlow-molecular-weight polysaccharidewithstableandcontrollablequality.Methods Takingtotalsugar,reducingsugarcontentandviscositypa-rameter as evaluating index,degradation methods of traditional acid hydrolysis,ultrasound-aided acid hydrolysis and enzy-matic degradation were compared and the process conditions were further optimized. The fenugreek gum and its degradation products were characterized by UV,IR and DSD spectrometry respectively. Results The reducing sugar content of different degradation methods were 52. 41% for enzymatic degradation,42. 19% for ultrasound-aided acid hydrolysis and 24. 59%for traditional acid hydrolysis. The optimum process was as follows:Fenugreek gum solution was treated with 10 U cellulose at 50 ℃ for 150 min. Repeated experiments showed that the degradation process was stable and controllable. No significant differences were found in the UV,IR or DSD spectrums between fenugreek gum and its degradation products. Conclusion Enzymatic degradation of fenugreek gum turned was an efficient,simple and controllable method.
