| 摘 要： | 分别从反应时间、臭氧产量、料液比和反应温度方面研究臭氧对魔芋溶液的黏度降解百分比(viscosity degradation percentage，VDP)和pH值的影响。结果表明：臭氧对魔芋葡甘露聚糖有较明显的降解作用，各个单因素试验的最优条件分别是反应时间1h、臭氧产量6g/h、料液比1%(g/ml)以及反应温度55℃，经此处理条件后的红外光谱表明：臭氧的强氧化性并没有使降解的产物发生明显的基团变化。

| Abstract: | Effects on viscosity degradation percentage (VDP) and pH value of konjac solution were investigated based on reaction time, ozone input amount, material/liquid ratio and reaction temperature, respectively. Ozone could effectively degrade konjac glucomannan (KGM). Single factor experiments indicated that the optimal degradation was obtained by 1 h reaction with an ozone input amount of 6 g/h and a material/liquid ratio of 1% at 55 ℃. No obvious changes in the groups of degraded products were observed in infrared spectra although ozone had strong oxidative capability. |
