Abstract
The change in quality of bananas ripened with an alcohol spray after an ethylene treatment were measured comparing with those of the bananas ripened with an ethylene treatment only. The possibility of a measurement in quality of bananas by an image processing system was also investigated.
The results were summarized as follows;
1) The sugar content and the color grade of the alcohol sprayed bananas were higher than those of the bananas which were treated with ethylene only.
2) The sugar content and the color grade of the bananas which were treated with 75% concentration of alcohol spray showed the highest values in all experimental conditions.
3) There was a high coefficient of correlation between sugar contents and the value of red in the chromatic coordinates of the banana skin.
4) There was a high coefficient of correlation between the color grade and the value of red in the chromatic co-ordinates of the banana skin.
