表皮对果蔬品质漫反射光谱检测精度的影响
Influence of Peel on Detecting Precision of Fruit and Vegetable Quality Using NIR Diffuse Reflectance Spectroscopy
摘要
Abstract
In this paper , nondestructive and quick determination of starch content of potato was studied using NIR diffuse reflectance spectroscopy , and the influence of peel on spectra and detecting precision was analyzed .The mean centering method , derivative , norris derivative filtering methods were used to processes the spectra , and the partial least square method ( PLS) and principal component regression method ( PCR) were used to develop calibration models .110 samples detecting results showed that it is feasible to detect potato starch content using NIR diffuse reflectance spectroscopy , and the peel influence the spectra and measuring precision .The performance of the model for starch content of peeled potato using the first Norris derivative spectra combined with PLS method ( r=0 .893 , RMSEC=1 .01%, RMSEP=1 .38%) , was more better than that for intact potato starch ( r=0 .834 , RMSEC=1 .29%, RMSEP=1 .74%) .The influence of peel should be corrected in fruit and vegetable quality detecting using NIR spectroscopy .关键词
