不同品种菊苣在货架贮藏期内的色泽变化

提出了判断不同品种菊苣在货架贮藏条件下色泽变化的一种实用光学方法。为了量化色泽变化采用了ＲＧＢ数字化数字化图象处理系统。借用ＨＩＣＵＰＰ命令树把观察表面的颜色分割成独立的４个色区。将６种菊苣用于试验。采用综合分化比较样品在货架贮藏期间的红褐变化。

Research on Color Change of Chicory During Different Shelf Storage

The methed of judging the color change during the shelf storage of different varieties of chicory by means of the RGB system is estabilished. Four colour areas are segmented according to the HICUPP decision tree. In the experiments, a cornprehensive indexis is used for estimating the unfavourable color change after comprehensive consideration of the area and degree of the color change. The translation among the segmented color areas is discussed, which explains that RGB values decrease during the shelf storage. In addition, the effects of red area and brown area on the color change.are also discussed seperately. The effect of commercial cut on the index are presented and analyzed.
