摘　　要：[目的]通过粘度计与流变仪两种不同仪器对发酵乳粘度进行测定分析,探究相同条件和因素影响下,两台仪器测定的准确性、便捷性和适用性。[方法]使用粘度计设备说明书、流变仪设备说明书对不同类型发酵乳进行粘度检测。[结果]流变仪与粘度计测定样品的相对标准偏差存在差异,样品组1偏差为-3.08%,样品组2偏差为+1.02%,样品组3偏差为-4.82%。样品组4是高粘稠样品,超出粘度计测定范围无法比较。[结论]对于低脂低蛋白类产品粘度测定,可优先选择粘度计;对于高粘稠产品粘度测定,流变仪测定范围更大,温控系统可精确至0.01℃。[Objective]The viscosity of fermented milk is measured and analyzed by two different instruments,viscometer and rheometer,and the influence of the same conditions and factors is explored.The accuracy,convenience and applicability of the two instruments are measured.[Method]Use viscometer equipment instructions and rheometer equipment instructions to detect the viscosity of different types of fermented milk samples.[Result]The relative standard deviation of samples measured by rheometer and viscometer was different.The deviation of Sample Group 1 was-3.08%,the deviation of Sample Group 2 was+1.02%,and the deviation of Sample Group 3 was-4.82%.Sample Group 4 high viscosity samples beyond the measurement range of viscometer cannot be compared.[Conclusion]For the viscosity measurement of low-fat and low-protein products,viscometer can be preferentially selected.For the viscosity measurement of high-viscosity products,the measuring range of rheometer is larger,and the temperature control system can be accurate to 0.01℃.
