摘要：

The performance of a commercially-available, portable NIR instrument "FT20" for fruit quality evaluation was investigated using mango fruits. The calibration result for the FT20 was compared with the result for the Foss NIRSystems 6500. Partial least squares (PLS) regression was used to make the calibration equations. It was found that the calibration equation using spectral data obtained with the FT20 had similar accuracy to that using Foss NIRSystems 6500 spectra. The SEPs of calibration equations were 0.40 degreesBrix for both instruments.
