Encapsulation of Red Cabbage (Brassica oleracea L. var.capitata L. f. rubra) Anthocyanins by Spray Drying using Different Encapsulating Agents BABT
Bernstein,Anahi; Noreña,Caciano Pelayo Zapata.
ABSTRACT This study aimed to evaluate the influence of the drying air temperature (140 and 160°C) and the concentration of encapsulating agents gum Arabic and polydextrose (10 and 15%) on the physicochemical characteristics of the red cabbage extract obtained through extraction in acidulated water and drying using a spray dryer. The anthocyanin retention, antioxidant activity, water activity, solubility, color and microstructure of the final product were analyzed. Results showed that increase in the temperature did not cause significant changes in the anthocyanin quantity and antioxidant activity. The microscopic analysis revealed that for both the encapsulating agents, the absence of fissures and porosity in the particle surfaces produced powder with high...

Development and description of light functional dulce de leche with coffee Ciência e Agrotecnologia
Guimarães,Ívina Catarina de Oliveira; Leão,Maria Helena Miguez da Rocha; Pimenta,Carlos José; Ferreira,Larissa de Oliveira; Ferreira,Eric Batista.
This study deals with development of a "dulce de leche" (DL) with coffee, with low caloric content and functional properties. Through rotational central composite design, eleven DLs were formulated with different polydextrose and sucralose levels. The results were analyzed by means of response surface and ANOVA. The addition of polydextrose led to the increase in moisture and water activity and reduction in the ash and soluble solids contents. In the formulations with greater levels of sucralose and polydextrose, there was an increase in the ash, acid and fiber content. Greater yield was achieved with greater concentrations of polydextrose and less substitution of sucrose by sucralose, allowing development of a new functional product with low caloric...
