摘　　要：文章通过分析魔芋的结构特性,并将它与海藻酸钠等材料相结合,制备出一种低成本高性能且可降解的魔芋葡甘聚糖吸管。通过测定该吸管的耐酸碱、力学拉伸等性能,筛选魔芋葡甘聚糖吸管的材料配比。通过研究发现,魔芋葡甘聚糖与海藻酸钠质量分数为4%且KGM∶SA为1∶1制备得到的吸管性能优异,具有良好的生物降解性。By analyzing the structural characteristics of konjac,and combining it with sodium alginate and other materials,a lowcost,high-performance and biodegradable konjac glucomannan straw was prepared.The paper screened the material ratio of konjac glucomannan straw by measuring its acid and alkali resistance,mechanical tensile properties,and other properties.It was found through research that the pipette prepared with the mass fraction of konjac glucomannan(KGM)and sodium alginate(SA)of 4%and the ratio of KGM to SA of 1∶1 had excellent performance and good biodegradability.
