摘要: Imaging the microstructure of opaque composite foodstuffs and extracting quantitative chemical information about specific localized components is challenging. Herein, a method has been developed to determine spatially resolved concentrations of aqueous salt and applied to measure salt concentrations of water droplets in butter samples. This was done using Coherent Anti-Stokes Raman Scattering (CARS) microscopy which achieves non-invasive label free imaging based on visualization of specific chemical-bond vibrations. The …
