基于近红外光谱技术的农产品产地溯源研究进展

Research progress of near infrared spectroscopy based geographical origin traceability of agricultural products

农产品产地溯源的目的是保证农产品的真实性,为地理标志产品、地区特征性产品产地真伪鉴别提供关键技术。近红外光谱是一种新兴的检测技术,因操作简单、绿色、高效、快速等特点,被广泛应用于农产品产地溯源研究中。本文介绍了近红外光谱分析技术的原理和特点,综述了基于近红外光谱技术的谷物、油料产品、水果等主要农产品产地溯源的研究进展,分析了现有技术存在的问题,并对今后农产品产地溯源的研究进行了展望,以期为近红外光谱技术在农产品产地溯源的进一步应用提供参考。

Geographical origin traceability of agricultural products is important technology to ensure the authenticity of agricultural products, which provides technical and theoretical basis for the traceability of geographical products and regional characteristic products. Near infrared (NIR) is widely used in geographical origin traceability of agricultural products due to its characteristics of simplicity, green, high efficiency and accuracy. This paper briefly summarized the principle and characteristics of NIR spectroscopy technology, and enumerated its current situation in researches on geographical origin traceability of agricultural products including fruits, grain and edible oils, and pointed out the corresponding problems and prospects in the future research on NIR based geographical origin traceability of agricultural products, in order to provide references for the further application of near infrared spectroscopy in the origin traceability of agricultural products.
