摘要:拉曼光谱技术是一种能够实现怏速、无损检测的高效检测技术,且加上拉曼光谱仪的操作简单、结果
准确等特点,目前该技术已被广泛的应用于生物、医药、材料等诸多领域,在粮食品质、结构检测方面同样具
有良好的应用前景。数据显示,每年受重金属污染的粮食高达1200万吨,引起了人们的担忧及重视,如何实现
粮食污染的简单快速鉴别,成为人们关心的问题。在此背景下,本文就当前拉曼光谱这一元损检测技术在粮食
检测领域中的应用进行了综述,以期为今后粮食的快速检测方法提供相应支持。文章介绍了拉曼光谱技术的原
理、分类以及拉曼光谱仪的结构,综述了拉曼光谱技术在大米、小麦、玉米等主要粮食检测中的应用现状,并
对其今后的研究发展前景进行展望

ABSTRACT: Raman spcctroscopy is a kind o high-eflicicncy detection Technology which can realize rapid and
non-destructive detection. The Raman spectroscopy is widely used in many fields such as biology, medicine and
materials because of its simple operation and accurate results. It also has a good application prospect in food qualit
and structure detcetion Data show that grain which has been contaminated by heavy metals cach year has reached up
to 12 million ton, causing peoples concerns and attention, thus how to achieve rapid and simple identification of food
contamination becomes an important question. Based on this background, the application of non-destructive Raman
spectroscopy Technology in grain inspection was reviewed in this papcr, so as to provide corresponding support for
the rapid dctection o! grain in the fulure. This paper introduced the principle, classification of Raman spectroscopy
and the structure of Raman spectrometer, summarized the application status of Raman spectroscopy in grain detection
including rice, wheat and corn, and discussed the future research prospects of Raman spectroscopy
