近红外光谱技术在食品掺伪检测应用中的研究进展

Application of Near-infrared Spectroscopy in Food Adulteration Detection:A review

近年来,我国食品掺伪现象严重。目前一些常用的食品掺伪检测方法费时费力,需要消耗大量的化学试剂。近红外光谱技术能够实现快速、无损、在线的食品掺伪检测。本文综述近红外光谱技术在食用油、牛奶、蜂蜜、饮料等液态食品和肉制品、奶粉、茶叶、小麦粉等固态食品掺伪检测应用中的研究进展,同时分析近红外光谱技术在掺伪检测中的局限性以及存在问题,并对今后的进一步研究提出展望。

In recent years,food adulteration has been a serious problem in China.Currently the common detection methods for food adulteration are both time and effort consuming,and need large amount of chemicals.Near-infrared spectroscopy achieves the rapid,nondestructive,and on-line detection for food adulteration.This paper summarizes the application of near-infrared spectroscopy in adulteration detection for liquid foods such as edible oil,milk,honey,and beverages,as well as solid foods including meats,powdered milk,tea,and wheat flour.Meanwhile,limitations of near-infrared spectroscopy in adulteration detection are analyzed.Finally,this article outlines further study directions and proposed some suggestions.
