Item Rheological parameters of mixed Brazilian Cerrado fruits sugar-free preserves : the effect of body agents.(2023) Farias, Taísa Rezende Teixeira; Schiassi, Maria Cecília Evangelista Vasconcelos; Pereira, Patrícia Aparecida Pimenta; Souza, Vanessa Rios de; Lago, Amanda Maria Teixeira; Borges, Soraia Vilela; Queiroz, FabianaThe aim of this study was 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). Mixture design was used for product optimization and the preserves were evaluated by texture profile, stress relaxation test, and uniaxial compression test. The research data were analyzed using regression equations on SAS software. The results indicated that the rheological parameters were affected by the body agents. Erythritol should not be used as an isolated component because it provoked changes in the properties of the final product (harder and brittle preserves); xylitol and sorbitol made preserves more elastic, cohesive, and more fragile; and polydextrose showed a synergistic effect with erythritol for rupture deformation and lesser effects for hardness, adhesiveness, and gumminess.Item Mixed Brazilian Cerrado fruits preserves without added sugar : the effect of bodying agents.(2019) Teixeira, Taísa Rezende; Schiassi, Maria Cecília Evangelista Vasconcelos; Pereira, Patrícia Aparecida Pimenta; Souza, Vanessa Rios de; Lago, Amanda Maria Teixeira; Borges, Soraia Vilela; Queiroz, FabianaPurpose: 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.Item Evaluation of the jelly processing potential of raspberries adapted in Brazil.(2014) Souza, Vanessa Rios de; Pereira, Patrícia Aparecida Pimenta; Pinheiro, Ana Carla Marques; Nunes, Cleiton Antônio; Pio, Rafael; Queiroz, FabianaGenerally raspberry products as jams, jellies, and preserves are made with red raspberry, however, yellow raspberry and especially black raspberry are also fruits adapted in Brazil, presenting even better productivity and quality. Thus, the aim of this study was to evaluate the processing potential of other varieties of raspberry, but the red, in the preparation of jellies through mixture design and response surface methodology (RSM). These techniques were used to optimize the following 3 variables: yellow (Golden Bliss cultivar, Rubus idaeus), black (Rubus niveus), and red raspberries (Batum cultivar, Rubus idaeus) to formulate a mixed raspberry fruit jelly through sensory evaluations. It was found that jelly formulated with a mix of colored raspberries grown in subtropical regions is a viable and alternative way to use yellow and black raspberries. The mixed raspberry jelly must have 0% to 30% yellow raspberries, 25% to 50% black raspberries, and 30% to 75% red raspberries. Within this region, the optimum formulation has ideal characteristics that are often not observed in formulations with 100% black or yellow raspberries.
