In the confectionery industry, there is considerable interest in understanding the mechanisms of liquid lipid migration inside chocolates as it relates to combating fat-bloom defects in confectionery products.  This thesis investigates the ability of MAS NMR spectroscopy to adequately resolve chocolate spectra and deliver diffusion data specific to individual chemical species. Using a Bruker 300 MHz spectrometer equipped with liquid state and hr-MAS probes various spectroscopic characteristics of a milk chocolate sample were recorded. The MAS spectrometer resolved the chocolate spectrum into individual chemical signals and demonstrated multi-compartment diffusion behavior.
