| Abstract This study aimed to evaluate the efficiency of aqueous extraction to obtain bioactive phytochemicals from grains and residual husk of organic Arabic coffee, as well as to develop a beverage with high antioxidant capacity and assess its sensorial acceptability. Aqueous extracts were obtained from dried and crushed coffee beans and husk. Various extraction methods were used to select the one capable of extracting the most amount of total phenolic constituents. The decoction without mechanical agitation was highlighted as the best method, from which the chemical characterization, antioxidant capacity and the presence of antinutrients were investigated. Three beverage formulations were prepared with coffee husk extract and added in different... |

| Abstract The objective of this research was to evaluate the quality parameters and the chromatographic, thermogravimetric, and spectroscopic profile of Patauá oil (Oenocarpus bataua). All analyses were performed according to the Recommended Practices of the American Oil Chemists’ Society (AOCS). The parameters obtained indicate conservation quality standards in accordance with Brazilian legislation. The fatty acid profile shows a predominance of ω-9, ω-6, and ω-3 fatty acids. The thermogravimetric behavior and differential analysis indicated good stability upon gradual temperature increase and the presence of endothermic and exothermic peaks characteristic of thermal and oxidative decomposition at high temperatures only. The spectroscopic profile evidenced... |

| Abstract These researches aimed determine the quality parameters, the nutritional profile, and the thermogravimetric and oxidative behavior of Muruci (Byrsonima crassifolia L .) oil obtained by supercritical CO2 extraction. The results showed an average oil yield of 5.50%. The acidity and peroxide values show good quality and conservation standards, according to the Brazilian legislation. The fatty acid profile indicates a predominance of unsaturated fatty acids with levels above 60%, highlighting the presence of fatty acids omega-6 and omega-9. The thermogravimetric curves showed oil stability at temperatures around 200 °C and exothermic peaks characteristic of mass loss close to 250 °C. The data of oxidative induction time determined by the Rancimat... |

| Abstract The effect of the food hydrocolloids Guar gum, Locust bean gum (LBG) and Gelatin, as well as their mixtures (even carrageenan was used in all formulations – 0.035%), was studied on the rheological characteristics of ice cream formulations. A frequency sweep test, at low temperature (-8 °C), was performed to evaluate the elastic (G’) and viscous (G”) modulus. The ice cream produced using Gelatin and blend of Gelatin and LBG (0.09 and 0.18%) presented higher values of G’, which is an indicative of the presence of ice crystals and greater rigidity. The thermo-oscillatory rheometry was used to correlate the rheological properties and the characteristic of the ice creams (creaminess, sensory, melting). A temperature sweep test, from -10 to 5 °C was... |

| Abstract Isotonic repositories are specially designed to promote rehydration during or after physical exercise. These beverages are processed for commercialization from synthetic flavorings and dyes with sensorial characteristics similar to those of fruits, in order to attenuate their natural acidity. The aim of the present study was to develop two formulations of isotonic drinks without synthetic dyes and with functional attributes based on concentrated hydroethanolic extracts of peel and pulp of Myrciaria jaboticaba. Determination of chemical (sodium, potassium and calcium, total phenolics, total anthocyanins, total flavonoids, total condensed tannins), physical (objective color analysis), and physical-chemical characteristics (pH, acidity, total soluble... |

| Abstract Cupuassu is a fruitful species from the Amazon basin with great economical potential, due to the multiple uses of its pulp and seeds in the food and cosmetic industries. This fruit generates large amounts of solid waste, which, despite of its high content of bioactive compounds, is discarded in the environment. Therefore, with the aim of reusing these wastes and adding economic value, we investigated the nutritional potential of the seed by-product resulting from industrial cupuassu oil extraction. The by-product was submitted to green extraction, and its contents of bioactive compounds were quantified by HPLC. The extract had a total polyphenol content (16.9 ± 1.8 mg/gDM) and an antioxidant activity, ABTS + (151.0 ± 5.5 mg/100 g) and DPPH. (85.4... |
