摘要硬质小麦的玻璃度被小麦工业用作制粉和蒸煮品质的指标。目前确定玻璃体透明度的目视方法是主观的，检查人员和国家之间的分类结果差别很大。因此，研究了利用近红外(NIR)光谱客观地对玻璃体和非玻璃体单核进行分类。结果表明，用近红外方法对明显玻璃体或非玻璃体核的分类与检查员的分类几乎完全一致。然而，当分析中包括难以分类的玻璃体和非玻璃体核时，近红外光谱程序仅在75%的核上与检查者一致。虽然近红外光谱对难处理核的分类与检查员的分类不能很好地匹配，但这种近红外光谱方法量化了玻璃体，因此可以提供一种客观的分类方法，可以降低检查员对检查员的可变性。分类似乎要到期了，在...
ABSTRACT The vitreousnss of durum wheat is used by the wheat industry as an indicator of milling and cooking quality. The current visual method of determining vitreousness is subjective, and classification results between inspectors and countries vary widely. Thus, the use of near-infrared (NIR) spectroscopy to objectively classify vitreous and nonvitreous single kernels was investigated. Results showed that classification of obviously vitreous or nonvitreous kernels by the NIR procedure agreed almost perfectly with inspector classifications. However, when difficult-to-classify vitreous and nonvitreous kernels were included in the analysis, the NIR procedure agreed with inspectors on only 75% of kernels. While the classification of difficult kernels by NIR spectroscopy did not match well with inspector classifications, this NIR procedure quantifies vitreousness and thus may provide an objective classification means that could reduce inspector-to-inspector variability. Classifications appear to be due, at ...
