NIR is an effective and easy tool to monitor + ensure the integrity of food and materials globally. There is inherent variability in the chemical composition of fruits, vegetables, and meat, which cannot be detected by color, shape, touch, or smell. Near-Infrared technology can identify and distinguish products based on their chemical composition. Hence, it is used for the processing of both plant and animal foods in the selection of raw materials to process control, ensure quality standards, and prevent tarnishing.
