The use of spectroscopy in food analysis is growing and this informative volume presents the application of advanced spectroscopic techniques in the analysis of food quality. The spectroscopic techniques include visible and NIR spectroscopy, FTIR spectroscopy and Laser-induced Breakdown Spectroscopy (LIBS). A wide range of food and beverage items are covered including tea, coffee and wine. The chapters will highlight the potential of spectroscopic techniques to enrich the food quality analysis experience when coupled with artificial intelligence and machine learning and provide a good opportunity to assess and critically lay out any future prospects. Different chapters have been written using a bottom-up approach that suits the needs of novice researchers and at the same time offers a smooth read for professionals. The book will also be of use to those developing spectroscopic facilities providing a useful cross comparison of the various techniques.

Four peaks in the Infrared (IR) spectral region of 1300 cm-1 - 1000 cm-1 were isolated for 13 sample spectra. The 1300 cm-1 - 1000 cm-1 region corresponds to the asymmetric stretching modes of the SiO2 crystal. The four peaks were compared based on their amplitudes, positions, and full width at half maximums. The comparisons were made in an effort to identify the ideal Pulsed Electron Deposition (PED) conditions and also to compare the PED method to another method, Electron Beam (E-Beam) deposition. The E-Beam deposition samples had stronger absorbance than the PED samples for all four peaks. This study found that the ideal growth temperature for PED of silicon dioxide is 850 °C which was the highest of all the growth temperatures. Also, the thickest samples, about 500 nm films, had the best IR characteristics. The Si substrate orientation also affected the SiO2 film. The {100} substrate orientation preformed worse than the {111} orientation.

Two-dimensional correlation spectroscopy has recently received keen interest from various fields of spectroscopy because it provides new opportunities for analyzing optical spectra. In the 2D approach, the spectral peaks are spread over the second dimension, thereby simplifying the visualization of complex spectra consisting of many overlapped bands and enhancing spectral resolution. 2D correlation spectroscopy has been applied to a wide range of science and technology such as life science, polymer science, and engineering, food and agricultural technology, as well as material science. This proceedings covers the wide aspects of 2D correlation spectroscopy ranging from theory to applications in these fields. This book offers a good opportunity to learn the state-of-the-art and future trends in 2D correlation spectroscopy.
