| Popis: | Chocolate is a two-phase rheological system. The solid phase, consisting of non-fat cocoa particles, sugar and soy milk is wrapped in a fat phase - cocoa butter. Physical, thermal, textural and organoleptic properties of chocolate depend on the composition of the ingredients, manufacturing process and a properly conducted pre-crystallization phase. For this study, two chocolate masses were produced in a ball mill: one with 15% of soy milk powder (R1) and the other with 20% of soy milk powder (R2). The chocolate mass was produced at different milling times (30, 60 and 90 min), and pre-crystallization temperature (26, 28 and 30oC). The aim of the study was to evaluate the changes caused by different amounts of soy milk powder on the quality of the chocolate. The quality of chocolate was evaluated by comparing the nutritional composition, hardness, thermorheological and thermal properties of the chocolate mass. The results show that chocolate mass R2, due to the presence of higher amounts of soy milk proteins, should be milled longer, and also needs lower temperatures for pre-crystallization.
