Eighteen Wavelengths Flagged Artificially Ripened Fruit
A non-invasive multispectral sensor separated calcium-carbide treatment from safer ripening methods while estimating progress and shelf life.
Summary
A non-invasive multispectral sensor separated calcium-carbide treatment from safer ripening methods while estimating progress and shelf life.
The study measures mangoes and bananas at 18 visible-to-near-infrared wavelengths and combines spectral ratios with temperature and humidity. XGBoost models reached 95 percent overall accuracy for mangoes with 0.67 recall on the carbide class, and 81 percent accuracy for bananas with 0.74 carbide recall. The method also estimates ripening progression and remaining shelf life. These are controlled-sample results; misses remain substantial enough that the prototype is not a standalone food-safety guarantee.
