ABSTRACT

High-resolution hyperspectral data of wavelengths ranging from the visible to the Near Infrared acquired from an experimental field of green vegetable soybeans were collected. The rapid detection of biological contaminants such as worms in fresh-cut vegetables is necessary to improve the efficiency of visual inspections carried out by workers. A rapid method based on hyperspectral imaging (HSI) for the detection of Escherichia coli contamination in fresh vegetables was developed. HSI could be a powerful tool for nondestruction evaluation of the internal quality of onions. Applications of HSI on soybeans are detection of insect damage, analysis of pigments, sweetness, color, and moisture, and checking for isoflavones and amino content. Soybeans are always dried to store and processed into snack food after harvest. White button mushroom is a medicinal edible and a main commercial variety of fungi for wide consumption by people around the world in form of raw or processed food.
