- ... The surface of 11wt.% fat cocoa particles was thoroughly investigated during a 2-month storage at 20 and 40°C and at aw=0.2. Surface fat migration was evidenced only for powders stored at 40°C by X-ray Photoelectron Spectroscopy. This was confirmed by ToF-SIMS, which allowed visualizing bigger fat patches at the surface of 40°C-stored powders. These observations emphasize that fat need to be under ...
