Dispersion of the CMC (0.5 g/100 g) was prepared at 25 C by
stirring at 63 s1 (Arde Barinco Inc., New Jersey); then a quantity
equivalent to 70 mg/mL of b-carotene in nanocapsules was added.
This dispersionwas used as a fluid model for the thermal treatment
study. Thermal conductivity was determined by a KD2 Pro® Thermal
Properties Analyzer (Decagon Devices Inc., USA) using a KS-1
sensor model, before and after the thermal treatment. All measurements
were performed in triplicate at 25 C.
