ABSTRACT
This chapter reviews the applications of hyperspectral imaging (HSI) in dairy products analysis and focuses on cheese analysis and authentication of dairy products. By acquiring the spectral information of the object, HSI can determine both the internal and external attributes of food. The HSI system consists of a light source to interact with the food sample, a light dispersion device, an imaging unit, and the computer hardware and software to make the decision. A linear correlation was observed between the hardness and the HSI reflectance at the significant wavelength of enzyme treatment. While HSI can be celebrated because of its unique properties, it is a pity that very few publications have been reported on its application in dairy products. Principal component analysis and partial least squares discriminant analysis of the spectrum functions showed good discrimination of blue cheese.
