Model development for soluble solids and lycopene contents of cherry tomato at different temperatures using near-infrared spectroscopy

The near-infrared (NIR) spectrometer is a powerful tool for rapid nondestructive testing of fruit, foodstuff and agricultural products in the laboratory. However, traditional NIR spectrometers are large and inconvenient to implement for online detection, and it is sensitive to external environmental factors such as temperature, which can affect products with high water content and decrease accuracy of measurements. A mixed temperature correction...
