Literature Review Title: Instrument-based detection methods for adulteration in spice and spice products – A review 
Chapter Title:  Hyper Spectral Imaging Principle 
1. Abstract of Cited Paper (BIB001):  Abstract Background The quality of products depends on their processing. Effective way of monitoring and controlling these processes will ensure the quality and safety of products. Since traditional measurement methods cannot achieve on-line monitoring, imaging spectroscopy, as a fast, accurate and non-destructive detection tool, has been widely used to evaluate quality and safety attributes of foods undergoing various processes. Scope and Approach In the current review, detailed applications of hyperspectral imaging (HSI) system in various food processes are outlined, including cooking, drying, chilling, freezing and storage, and salt curing. The study emphasized the ability of HSI technique to detect internal and external quality parameters in different food processes. Also, the advantages and disadvantages of HSI applications on these food processes are discussed. Key Findings and Conclusions The literature presented in this review clearly demonstrate that HSI has the ability to inspect and monitor different food manufacturing processes and has the potential to control the quality and safety of the processed foods. Although still with some barriers, it can be expected the HSI systems will find more useful and valuable applications in the future evaluation of food processes.

Literature Review:
Hyper spectral imaging (HSI) combines both, conventional imaging and spectroscopic imaging, and has a wide application in food and agricultural product quality and safety analysis. Essentially, HSI acquires both spatial and spectral features simultaneously BIB002 BIB001 . Hyper spectral images are made up of a number of neighbouring wavebands for each spatial position of a sample being studied. Consequently, the spectrum obtained for each position acts as a fingerprint that helps in characterisation of the particular pixel in that position (Elmasry et al. 2012; Shaw & Manolakis 2002) .
