Non-Destructive Fruit Analysis with High-Performance Near-Infrared Spectrometers for Sugar and Moisture Measurement

Employing near-infrared light spectroscopy, our spectrometers deliver instant, non-contact fruit analysis. They measure critical quality markers including sugar content, acidity, and moisture levels, enabling precise fruit grading and informed processing decisions without sample destruction.

The versatile JINSP SR100N spectrometers support 0.9-2.5μm detection range, with specialized models for 1.7μm & 2.5μm cutoff. Featuring advanced optical filtering and a low-noise InGaAs array (512px), these instruments excel in NIR spectroscopy applications across multiple sampling techniques.

The NIR region (780nm-2500nm) reveals molecular vibrations through light absorption. Spectral data from agricultural samples show characteristic broad bands due to harmonic vibrations of chemical bonds (N-H, O-H), providing both chemical fingerprints and compositional data for quality analysis.

• Near-infrared reflection detection: Suitable for detecting surface information on fruit peels, such as color and luster, but not for internal quality analysis.
• Near-infrared transmission detection: Theoretically applicable to transparent or semi-transparent samples, but cannot penetrate most fruits. Limited practical application.
• Near-infrared diffuse reflection detection: A measurement method between reflection and transmission, ideal for opaque, solid and semi-solid samples. The obtained spectral information reflects internal fruit structure characteristics, widely used for detecting internal qualities like sugar content and acidity.

• Quality assessment: Predict quality parameters including firmness, sweetness, and acidity of fruits.
• Classification and identification: Distinguish and identify different fruit types.
• Functional fruit evaluation: Evaluate and screen functional fruits rich in special components.
• Disease monitoring: Quickly diagnose diseases such as citrus Huanglongbing and provide early warnings for prevention.
