The sucrose-free dark chocolate development is receiving attention due to increasing market demand for foods with reduced sugar. This study aimed to determine the physical and sensory properties, and the storage stability of sucrose-free dark compound chocolate by replacing the sucrose with inulin, Fructo-oligosaccharides (FOS), trehalose, or maltodextrin (M10 and M30) on a volume basis along with stevioside as a sweetening agent. Melting and crystallization properties, particle size, moisture content, rheological behaviour, hardness, bloom formation and sensory evaluation were examined using differential scanning calorimetry, particle size analyser, rheometer, and texture analysis, respectively. Sucrose substitution had no significant impact on the melting and crystallization behaviour in a compound chocolate model system. However, all sucrose-free dark compound chocolate displayed lower Casson viscosity, yield value and hardness than sucrose-containing dark compound chocolate, which may because the weaker particle-particle interaction in sucrose-free dark compound chocolate. Sucrose-free dark compound chocolate had lower sweetness (P < 0.05) and stronger bitterness (P < 0.05) compared to the sucrose compound chocolate. Trehalose was the most suitable sucrose replacer in dark compound chocolate because it resulted in similar rheological and sensory properties as the sucrose-containing dark compound chocolate and greater resistance to bloom formation after 12 weeks of storage.
