In potato processing factory, selection and resorting are done by external quality like as surface color, feature size, decay and greening. Although greened potato tubers are sorted in the factory, PGA potatoes are not sorted because of their unvaried color on the surface. As the result, potatoes including high PGA concentration are distributed and used as food materials,In this study, nondestructive rapid determination of natural toxin concentration in potato is discussed by using image processing in order to confirm the existence of low greening and high PGA. The experimental apparatus is consisted of light source, optical fiber, dark box and hyperspectral image processor. Absorption characteristics of transmitted light on of the potato surfaces are measured.The relationship between PGA concentration and absorbance ratio of the transmitted light was discussed. The existence of low greening and high PGA was confirmed by the result that the potatoes one hour light exposing a day showed the higher absorbance ratio than that of non light exposing. The possibility of estimation method for the PGA concentration was suggested by using the result of the analysis of first derivation of absorbance.

马铃薯加工厂根据表面颜色、特征尺寸、腐烂、绿化等外观质量进行选择和分拣。虽然绿色的马铃薯块茎在工厂里被分类，但PGA马铃薯没有被分类，因为它们的表面颜色不变。因此，含有高浓度PGA的马铃薯被广泛用作食品原料。本研究探讨了利用图像处理技术无损快速测定马铃薯中天然毒素含量的方法，以确定低绿度高PGA的存在。实验装置由光源、光纤、暗箱和高光谱图像处理器组成。测定了马铃薯表面对透射光的吸收特性，讨论了PGA浓度与透射光吸收率的关系。每天光照1小时的马铃薯吸光度比不光照的高，证实了低绿高PGA的存在。利用吸光度一阶导数分析结果，提出了PGA浓度估算方法的可行性。
