Assessment of magic angle spinning spectroscopy for studying migration in solid milk chocolate

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. [1] 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.
