| ABSTRACT This study aimed to produce microcapsules using ‘jabuticaba’ byproduct through lyophilization, and evaluate the stability of the powder, intended for use in gelatin. Three formulations were prepared, including the pure lyophilized extract (E), capsule with maltodextrin (CapM), and capsule with maltodextrin and xanthan gum (CapMG). The storage stability was evaluated at 4 and 25 ºC, and in the presence and absence of light, regarding color parameters, phenolic compounds and monomeric anthocyanins. The microencapsulated powders were applied in gelatin and analyzed for sensorial acceptance. Following an investigation of the storage stability of the three powders at 4 °C for 60 days, the sample that presented the best result was then analyzed at 25 ºC... |

| ABSTRACT Equilibrium moisture data from the powdered pulp of Spondias mombin, L., both with and without additives - 58% maltodextrin (MD) or 58% gum arabic (GA) - were determined at 20, 30, 40 and 50 °C, using the static gravimetric method for a water activity range of 0.06 to 0.90. The resulting isotherms were sigmoidal and typical Type III, with the Guggenheim-Anderson-de-Boer model (GAB) adjusted to the experimental data for equilibrium moisture vs water activity. The addition of additives was shown to affect the isotherms in such a way that, for the same water activity, samples of CP+GA and CP+MD showed a lower equilibrium moisture content and were not affected by the variations in temperature. The isosteric heat of sorption for the cajá powder with... |

| ABSTRACT The aim of this work was to study the stability of powdered mango pulp obtained through the process of lyophilisation, as well as its structural characteristics using electron microscopy analysis. In response to an earlier experimental design using maltodextrin concentrations of 0%, 10%, 20% and 30% and periods of 24 and 30 hours, the condition of 20% maltodextrin and 24 hours drying was chosen as the best for drying mango in a freeze dryer. The stability study was therefore carried out using powdered mango pulp obtained under the above best-drying conditions, stored for 90 days and monitored every two weeks by analysis of the moisture, ascorbic acid content, b* colorimetric parameter and hygroscopicity. Storage was at room temperature (27 °C) in... |
