Non-linear microscopy is introduced for three-dimensional, label-free imaging of provitamin-A-carotenoids and starch granules in plant tissues. Carotenoids in orange-fleshed sweet potato (OFSP), carrot and mango were visualized by CARS microscopy and related to the plant-matrix morphology by simultaneous SHG microscopy of starch granules. While OFSP and carrot showed rod-shaped bodies with high carotenoid densities, the carotenoid-filled lipid droplets in mango appeared as low-density aggregates of rounded shape. Thermal processing of OFSP showed intact carotenoid bodies despite significant changes of the surrounding starch granules. This illustrates the value of non-linear microscopy also within the plant biology and food sciences.
