Light absorption in the NIR spectrum (780-2500nm) excites molecular vibrations that produce characteristic spectra. The broad peaks observed in agricultural products result from combined vibrations of functional groups, making NIR ideal for simultaneous chemical and compositional analysis.
- Near-infrared reflection detection: Suitable for surface analysis of fruit peels (color, luster) but not internal quality assessment.
- Near-infrared transmission detection: Primarily for transparent or semi-transparent samples; limited application for fruit analysis.
- Near-infrared diffuse reflection detection: The most effective method for opaque, solid samples, providing spectral information that reflects internal fruit characteristics (sugar content, acidity).
- Quality assessment: Precise measurement of firmness, sweetness, and acidity in fruits.
- Classification: Accurate identification and sorting of different fruit varieties.
- Functional fruit evaluation: Screening for fruits with special nutritional components.
- Disease monitoring: Early detection of conditions like citrus Huanglongbing for preventive measures.
