Application of hyperspectral imaging technology in nondestructive detection of food quality

Hyperspectral imaging combines the advantages of imaging and spectroscopy,and can acquire spectral and image information simultaneously in one system very well.Its rich spectral information is sufficient for internal feature extraction.Hyperspectral imaging has been applied to assess moisture content,freshness and biological pollution and so on.This paper briefly reviewed the applications of hyperspectral imaging technology in food inspection,discussed the disadvantage of hyperspectral imaging technology,pointed out key issues in this area,on which should be focused in future and highlighted the prospect for development of hyperspectral imaging technology.
