Non-destructive characterization of crop and food postharvest quality

Rapid and non-destructive characterization of post-harvest quality of seeds, fruits, and vegetables is paramount to increasing crop profitability for growers and nutritious value and product quality for customers. Furthermore, simulation techniques with measurements of tissue characteristics can establish reference datasets providing scientists useful information for understanding of tissue development at the fundamental level. Our lab has developed non-destructive sensing techniques (such as: hyperspectral imaging, electronic nose, and thermal imaging) for various crop postharvest quality sensing such as blueberry internal bruising, onion postharvest diseases, and cotton fiber foreign matter.
