摘要: 【目的】 验证FOSS-InfratecTM Nova近红外谷物品质分析仪已建小麦、玉米、高粱模型的精确性和稳定性。【方法】 对比仪器中两个检测单元(容重模块TWM检测单元和STM样品传送单元)间小麦、玉米、高粱的水分、蛋白质、淀粉含量检测结果,并对STM检测单元中不同光程下水分、蛋白质、淀粉含量与化学方法检测值进行对比。【结果】 小麦在STM单元18 mm光程下、玉米在STM单元29 mm光程下样品水分、蛋白质、淀粉含量检测值与TWM和化学方法检测值间差异不显著(P>0.05),高粱在STM不同光程下样品水分、蛋白质、淀粉含量检测值与化学方法检测值拟合度不高且相关性不一致。【结论】 小麦和玉米已建模型分析性能稳定、结果可靠;高粱模型检测性能较差,需进一步校准或重建模型。

Abstract: 【Objective】To verify the accuracy and stability of the established wheat,maize,and sorghum models of the FOSS-InfratecTM Nova near-infrared grain quality analyzer.【Methods】To compare the moisture,protein,and starch content detection results of wheat,maize,and sorghum between the two detection units (bulk density module TWM detection unit and STM sample transfer unit) in the FOSS-InfratecTM Nova near-infrared grain quality analyzer,and the moisture,protein,and starch content under different optical paths and chemical method detection values in the STM detection unit.【Results】There was no significant difference(P>0.05) between the moisture,protein,and starch content detection values of wheat samples at an STM unit of 18 mm optical path and maize samples at an STM unit of 29 mm optical path and the detection values of TWM and chemical methods,The moisture,protein,and starch content detection values of sorghum samples at different STM optical paths were not well fitted and correlated with the detection values of chemical methods.【Conclusion】The established models for wheat and maize have stable performance and reliable results in analysis;The detection performance of the sorghum model is poor,and further calibration or reconstruction of the model is needed.
