| ABSTRACT One of the factors that hinder the usability of Cerrado fruits is their perishable nature, requiring industrial processing to ensure prolonged shelf life. This study aims to determine the optimal foaming agent for industrial processing of this fruit, and to evaluate the physicochemical characteristics and antioxidant activity of dried cagaita powder (Eugenia dysenterica DC) in foam layers at temperatures of 40, 50, 60, and 70 °C. The effectiveness of three foaming agents at various concentrations were tested, and suitable agents were identified based on a factorial analysis of density, expansion, and stability. The physicochemical characteristics of the powder, along with its vitamin A and C and total carotenoid content and antioxidant activity,... |

| 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... |
