高光谱成像在食品质量评估方面的研究进展与应用(一)

Researches and Applications of Hyperspectral Imaging in Food Industry(Ⅰ)

近年来频发的国内食品质量与安全问题受到全社会的高度重视。因此,需要采用现代化检测技术快速、准确获取食品品质和安全信息。高光谱成像技术是一项将光谱与成像科学相结合的光学分析技术。通过同时获取食品的光谱和空间图像信息,高光谱成像技术能够快速、无损获取食品的品质信息及其空间分布,从而实现食品内外部品质信息的全方位检测,因此在食品安全检测应用领域具有巨大潜力。本文介绍了高光谱成像技术的基本原理,并综述了其在肉类品质检验方面的研究进展。

In recent years, the quality and safety issues of food have attracted much attention of the whole society in China. Modern inspection techniques are required for rapid and accurate assessment of quality and safety of food products. Hyperspectral imaging is an optical analysis technology with integration of spectroscopy and imaging techniques. By acquiring both spectral and spatial information of food simultaneously, hyperspectral imaging can inspect quality information with spatial distribution of food products rapidly and non-destructively, leading to an overall inspection of external and internal quality attributes. Therefore, hyperspectral imaging is a very promising technique in the safety inspection field of food products. This paper presents the basic principles of hyperspectral imaging and outlines in details its applications in the meat industry.
