光谱无损检测技术在农产品产地溯源中的研究进展

Research Progress of Spectral Nondestructive Testing Technology in Traceability of Agricultural Products

实现农产品产地溯源的无损检测,是建立农产品质量安全追溯体系的重要途径,也是保障食品安全质量、维护消费者合法权益的有效手段。相比于传统的检测方法,无损检测技术因其能实现不破坏被检样品的同时获取内外部有效信息的优点而被广泛应用于食品的产地溯源领域。本文主要概述了近红外光谱、高光谱成像、拉曼光谱三种光谱检测技术的原理及其在不同种类可食用农产品产地溯源中的最新应用现状,得出各光谱检测技术在农产品产地鉴别方面具有一定的可行性,同时对未来的研究方向作了展望,以期为农产品产地溯源的无损检测技术体系研究提供理论参考。

Realizing nondestructive testing for traceability of the origin of agricultural products is an important way to establish a traceability system for the quality and safety of agricultural products,and an effective means to guarantee the quality of food safety and safeguard the legitimate rights and interests of consumers.Compared with traditional testing methods,nondestructive testing technology is widely used in the field of food traceability because it can achieve the advantages of obtaining internal and external effective information without damaging the inspected samples.This paper provides an overview of NIR spectroscopy,NIR testing,and NIR testing.In this paper,the principles of three spectral detection techniques,namely,near-infrared spectroscopy,hyperspectral imaging and Raman spectroscopy,and their latest applications in the origin traceability of different types of edible agricultural products are outlined,and the feasibility of each spectral detection technique in the origin identification of agricultural products is concluded.At the same time,the future research directions are prospected in order to provide theoretical references for the research of nondestructive testing technology system for origin traceability of agricultural products.
