Quality of honeys from different botanical origins.

Botanical origin is one of the principal factors influencing the composition and quality of honey. This study aimed to evaluate different single-flower (assa-peixe, coffee, eucalyptus, laranjeira, and vassourinha), polyfloral (silvestre), extrafloral (sugarcane), and honeydew (bracatinga) honeys with regard to their chemical, physicochemical, and physical properties; rheological behavior; bioactive compounds; and antioxidant activity. In addition, we assessed their sensory characteristics using the acceptance test and the check-all-that-apply test (CATA). All honeys were compliant with current legislation and presented Newtonian behavior. The honeys of assa-peixe, laranjeira, and coffee presented the highest viscosity, sugarcane honey showed the highest antioxidant activity, and the bracatinga honey had the highest phenolic compound content. With respect to sensory characteristics, floral honeys presented higher acceptability than did honeydew and extrafloral honeys, because honey from honeydew was negatively influenced by its bitter, alcoholic, and astringent taste and extrafloral honey by its burnt smell. These findings indicate that the botanical origin directly influences the characteristics of honeys and can be considered a factor for their differentiation.

Fruits from the Brazilian Cerrado region: Physico-chemical characterization, bioactive compounds, antioxidant activities, and sensory evaluation.

Given the economic importance of fruit processing, this study aimed to analyze the chemical composition, antioxidant activity, and sensorial acceptance of six fruit pulps from the Brazilian Cerrado. For bioactive compounds of the selected fruits, buriti contains the highest carotenoid content (2.85 mg licopene/100 g e 4.65 mg ß-carotene/100g), however showed the lowest ascorbic acid concentration (7.42 mg/100g); while mangaba contains the highest ascorbic acid concentration (175.06 mg/100g), but obtained the lowest total phenolic compounds (46.85 mg GAEs/100g) and antioxidant capacity. The marolo reported the highest total phenolic compounds (728.17 mg GAEs/100g), total fiber (21.62%), and a high antioxidant potential. Regarding the mineral composition, marolo stood out as potassium (378.69 mg/100g) and magnesium (31.78 mg/100g) contents, and yellow mombin as phosphorus (26.24 mg/100g) content. Finally, juice prepared using cagaita and marolo had greater sensorial acceptance. The composition of fruit pulps indicated the potential there for the development of new food products.
