In this study, a low cost agricultural waste product – mangosteen
pericarp – was added as a source of plant polyphenols to dark
and compound chocolates during the mixing stage and evaluated.
The particle size distributions of the chocolates were mostly within
30 lm and the chocolates displayed a homogeneous morphology.
The polyphenols (procyanidins and xanthones) in mangosteen
pericarp powder were also stable to simulated chocolate processing.
The 3% pericarp powder concentration significantly expanded
the bioactive profile and total phenolic content of the chocolates
without affecting the sensory qualities. This serves as a model for
the use of plant polyphenols to be low cost solutions to enhance
the nutritional and sensory properties of chocolates, especially in
low cocoa content compound chocolates.
