ABSTRACT
This study aimed to develop and evaluate bread with the use of pulp and flours of pequi, in partial replacement of water and wheat flour, to develop a bakery product with good technological, nutritional and sensorial qualities. The pequi husk and pulp flours were obtained by means of a thermal pre-treatment, oven drying and standardization of the dry material. Whereas, the bread formulation was defined through the baker's formulation. Besides, the dehydration process caused significant changes (p<0.05) in the L* value and chromaticity (C*), mainly of the flours (husk and pequi pulp), such changes are due to non-enzymatic oxidative processes and pigment degradation, especially carotenoids. The effect of the substitution of ingredients (wheat flour and water) by husk and pulp flours and pequi pulp contributed to the increase in lipid, crude fiber, nitrogen-free extract and energy value content. However, the substitution promoted changes in the attributes of color and textural properties, such as increased hardness, chewiness and cohesiveness. Nevertheless, all formulations showed good sensory acceptance and thus, pequi sweet breads can be implemented in school meals for contributing and meeting the nutritional recommendations established by the School Feeding Brazilian Program (PNAE).

BACKGROUND: Nutritional intervention with the use of phytochemicals is an important method for the treatment and prevention of a metabolic syndrome. The objective of this study was to chemically characterize Moro orange juice. The influence of juice intake on metabolic parameters of rats that were obese, diabetic or both by means of body mass management after the activation of anthocyanins during refrigerated storage was also assessed. RESULTS: Juice intake reversed most of the metabolic abnormalities exhibited by obese rats, including reduction of body mass and improvement of the biochemical profile. The loss of body mass by diabetic animals and obese and diabetic animals was not attributed to juice intake, but to type I diabetes mellitus. In these animals, no improvement was observed in the biochemical profile, liver enzymes and glycemia, so this treatment model was deemed unfeasible. CONCLUSION: The beneficial effects cannot be explained only by the anthocyanin C3G present in the juice, but rather, by the synergism between all the components. Studies in humans are needed to determine whether the ingestion of this orange can be recommended as an effective strategy to prevent or ameliorate complications of obesity. © 2020 Society of Chemical Industry.
