Advanced Near-Infrared Spectrometer for Non-Destructive Detection of Fruit Properties in the Food and Agriculture Industries

Fruit quality assessment is revolutionized by NIR spectroscopy, a rapid and contactless method that analyzes near-infrared light interactions with fruit tissues to quantify key components such as sugars and acids, streamlining quality control in agricultural production.

The JINSP SR100N17 and SR100N25 near-infrared refrigerated spectrometers are versatile instruments with applications spanning a broad wavelength range of 0.9 to 1.7μm or 0.9 to 2.5μm, respectively. These spectrometers feature:

• Integrated light filters that effectively screen out visible light
• Removal of high-order modes
• Cooled 512-pixels area array InGaAs sensor for high resolution
• Minimal stray light interference
• Suitable for transmission, reflection, or absorption methods

The 780-2500nm NIR region captures molecular vibrations through light absorption, generating spectra with overlapping peaks from functional groups like C-H and O-H. These spectral features allow non-destructive analysis of complex agricultural matrices, revealing chemical composition and quality traits.

• Near-infrared reflection detection: Suitable for detecting surface information of fruit peels, such as color and luster, but not for internal quality detection.
• Near-infrared transmission detection: Theoretically applicable to transparent or semi-transparent samples, but less used in practical fruit applications.
• Near-infrared diffuse reflection detection: A measurement method between reflection and transmission, suitable for opaque, solid and semi-solid samples. The obtained spectral information reflects the characteristics of the internal structure of fruits and is widely used in the detection of internal qualities (such as sugar content, acidity).

• Quality assessment: Predict quality parameters such as 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 disease prevention.
