梨果实容易发生果肉褐变，即使外观完好，也有可能内部发生劣变。近红外光谱(NIRS)分析技术以其快速、无损、多组分同时测定等优势，近年来在梨果实无损检测应用的研究中取得重要进展。本文介绍了NIRS检测技术的原理与方法，综述了国内外应用NIRS无损检测技术在梨糖度、酸度、硬度等内部品质、褐变和损伤等内部缺陷方面及便携式检测的研究进展，并对其存在的问题及应用前景进行了展望。

Brown heart is an internal disorder mostly seen in pears. The symptoms of the disorder contain unsightly flesh browning around the core, and cavities in affected flesh where browning extends into the cortex. But the external symptoms signaling the presence of the disorder are absent. Near infrared spectroscopy (NIRS) had been widely used in the non-destructive analysis for pears due to its rapid, non-destructive and multicom-ponent simultaneous determination. This review introduced the principle and methods of NIRS technology, and summarized the progress on NIRS applications in internal and external quality measurement of pear fruit, and also on portable detection NIRS. Finally, future prospects for NIRS were explored.
