Summary

A low cost optical chlorophyll sensing system was developed to detect the cholorophyll content of bananas during ripening. This system shows a high correlation to other peel color analysis methods (spectral analysis, tristimulus colorimeter analysis, and visual color matching) and is suited for automatic monitoring of banana ripening.

Objectives

• Develop an inexpensive optical chlorophyll sensing system
• Determine the correlation between the optical chlorophyll sensing system measurements and chlorophyll content of banana peel measured by chemical analysis.
• Determine the correlation between chlorophyll content and color difference meter measurement and visual color assessment
