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. It analyzes near-infrared light interactions with fruit tissues to quantify key components such as sugars and acids, streamlining quality control in agricultural production.

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 are equipped with integrated light filters that effectively screen out visible light and remove high-order modes. Additionally, they feature a cooled 512-pixels area array InGaAs sensor, ensuring high resolution and minimal stray of light. These spectrometers are suitable for detecting near-infrared spectra through 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 method: Suitable for detecting information on the surface of fruit peels, such as color and luster, but not for internal quality detection.
• Near-infrared transmission detection method: Theoretically applicable to transparent or semi-transparent samples and cannot penetrate fruits. Less used in practical applications.
• Near-infrared diffuse reflection detection method: A measurement method between reflection and transmission, suitable for opaque, solid and semi-solid samples. The obtained spectral information can reflect the characteristics of the internal structure of fruits and is widely used in the detection of internal qualities of fruits (such as sugar content, acidity, etc.).

• Quality assessment: Predict quality parameters such as firmness, sweetness, and acidity of fruits.
• Classification and identification: Distinguish and identify the types of different fruits.
• Functional fruit evaluation and screening: Can be used to evaluate and screen functional fruits rich in special components.
• Disease monitoring: Can quickly diagnose diseases such as citrus Huanglongbing and provide early warnings for disease prevention and control.
