无损检测技术在食品安全快速筛查中的应用

Applications of nondestructive detection technology in food safety rapid screening

食品安全是当前"健康中国"建设的重要组成部分,保障食品安全需要加强食品安全监管,加大食品安全的筛查力度,因此对食品安全筛查的技术手段提出了更高的要求。无损检测技术是近年来发展起来的高科技技术之一,在食品安全快速筛查中应用广泛。本文综述了6种无损检测技术包括近红外光谱检测技术、拉曼光谱检测技术、X射线检测技术、超声波检测技术、计算机视觉检测技术及电子鼻检测技术在国内外食品安全快速筛查中的应用现状,并对当前无损检测技术存在的问题、技术难点及今后发展方向进行了探讨。

Food safety is an important part of the construction of ＂healthy China＂ now,and it is necessary to strengthen food safety supervision and increase the intensity of food safety screening so as to ensure food safety.Therefore,the technical requirements for food safety screening are put forward higher requirements.Nondestructive detection technology is one of the high-tech technologies developed in recent years,which is widely used in rapid food safety screening.In this paper,the application status of six kinds of nondestructive detection technologies in food safety rapid screening at home and abroad were reviewed,including near-infrared spectroscopy,Raman spectroscopy,X-ray,ultrasonics,computer vision and electronic nose detection,and then the existing problems,technical difficulties and the future development direction of nondestructive detection technology were discussed.
