    Purpose: The purpose of this paper is to evaluate the effect of the bodying agents (erythritol, sorbitol, xylitol and polydextrose) and their mixtures on the preparation of mixed Brazilian Cerrado fruit preserves (marolo, soursop and sweet passion fruit). Design/methodology/approach: The simplex mixture design was used for product optimization and the preserves evaluated by physical, physicochemical and sensory properties. The research data were analyzed using regression equations on SAS University and exploratory analysis by principal component analysis and parallel factors techniques on Sensomaker software. Findings: The results show that erythritol and polydextrose bodying agents should not be used as pure components because they provoked changes in the properties of the final product and negatively influenced the sensory attributes. While the high concentrations of xylitol and sorbitol provided better sensorial acceptance, being considered, therefore, good substitutes for sucrose. Practical implications: This research has shown it is feasible to use bodying agents in the preparation of mixed Brazilian Cerrado fruit preserves without added sugar. Social implications: The development of mixed preserves could increase population access to the Brazilian Cerrado fruits. In addition, sugar-free preserves are a viable alternative for adding value to the product and satisfy all the consumers. Originality/value: The combination of properties of two or more fruits and use of bodying agents can improve sensory, physical and physicochemical characteristics of the final product. However, there are technological challenges to evaluate in the preparation of mixed Brazilian Cerrado fruit preserves without added sugar.
