| ABSTRACT Yellow mombin has high nutritional value but is very perishable. Foam mat drying is a method that has been widely used to preserve liquid and semi-solid powdered foods. In this context, the aim of this study was to determine desorption isotherms and isosteric heat of yellow mombin (Spondias mombin L.) foam for different conditions of temperature and water activity. Powdered yellow mombin pulp was obtained by drying in forced-air oven regulated to 60 ° C. The indirect static method was used to determine the isotherms and isosteric heat, whereas water activity (aw) was determined using the Hygropalm-HP23AW-A analyzer. A B.O.D. incubator, set at 10, 20, 30 and 40 °C, was used to control the temperature, and the water activity for each temperature was... |

| ABSTRACT The objective of this work was to perform foam-mat drying of yellow mombin pulp, verifying the kinetics and mathematical modeling of the process, and characterizing the obtained product with respect to physical and chemical characteristics, compared with the fresh pulp. Foam-mat drying was carried out with the aid of the foam agent Emustab®, at temperatures of 50, 60, 70 and 80 °C. The drying data were analyzed and fitted to four mathematical models (Wang & Singh, Verma, Page and Midilli). Effective diffusion coefficient and activation energy were determined. Titratable acidity, pH, soluble solids content and vitamin C content, as well as the solubility in water of yellow mombin powder and color variance (L*, a*, b*) were analyzed in both... |

| Abstract: The Cerrado is one of the world's biodiversity hotspots and Brazil’s second largest biome. Many native species of the Brazilian Cerrado provide fruits that have unique sensory characteristics and high nutritional value. This study aimed at characterizing the pulp of Eugenia klotzschiana O. Berg, concerning its proximal composition, bioactive compound content and antioxidant activity. The pulp under study had high moisture (89.47 g kg-1) and caloric (96.07 kcal kg-1) values whereas its contents of protein (0.59 g kg-1) and lipids (2.35 g kg-1) were low. The cerrado pear pulp also had high iron content (16.5 mg kg -1) and dietary fiber (6.45 g kg-1), besides 0.034-0,055 mg kg-1 carotenoids, 8.66 mg kg-1 ascorbic acid and 0.66 mg kg-1 total... |
