Sugar (sucrose), xylitol (P98.5%, Carl Roth GmbH + Co. KG) and
isomalt (Cargill GmbH, Germany) were used as binders. Cocoa
powder (Gepa The Fair Trade Co., Germany) with particle sizes
smaller than 160 lm was chosen as a food candidate. The cocoa
powder is the highly defatted cocoa with the cocoa butter content
of 10–12 wt% and K2CO3 as impurities. Distilled water was used as
