13. Estudo da técnica de leito de jorro convencional para secagem de microcápsulas de caseína e pectina / Study of conventional spouted bed on casein and pectin microcapsule drying
The use of spouted bed technique in the drying of paste has been subject to many researches in the past years due to the possibility of obtaining high quality products at low cost. In present work the influence of this technique on microcapsule drug delivery systems performance was evaluated. Casein-pectin microcapsules with entrapped indomethacin and acetam

14. Produção e caracterização de microparticulas obtidas por spray drying e coacervação complexa e seu uso para alimentação de larvas de peixes. / Production and characterization of microparticles by spray drying and complex coacervation and its use for feeding of larvae fish.
A microencapsulação é uma técnica para recobrimento de substâncias para a proteção e/ou liberação controlada das mesmas. As microcápsulas podem ser uma alternativa para obtenção de uma dieta para alimentação das larvas de peixe na piscicultura intensiva. Dois métodos de microencapsulação foram empregados para produção de micropartículas,

15. Interação de proteinas do soro de leite com polissacarideo : fracionamento e estudo das propriedades funcionais dos complexos. / Protein interaction of the milk serum with polissacarídeo : fracionamento and study of the functional properties of the complexes.
In dairy industries the coacervation between whey with hydrocolloid might be utilized in the fractionation and recovery of the proteins and contribute to reduce in the ambient pollution. The aim of this work was to study whey protein interaction as a result of cheese type "Minas" manufacturing with anionic polysaccharyde carboxymetyl-cellulose (CMC) using th

16. Structural analysis of microparticles by confocal laser scanning microscopy
This study demonstrates the potential of conforcal laser scanning microscopy (CLSM) as a characterization tool for different types of microparticles. Microparticles were prepared by various methods including complex coacervation, spray drying, double emulsion solvent evaporation technique, and ionotropic gelation. Protein drugs and particle wall polymers wer

17. Designing chitosan-dextran sulfate nanoparticles using charge ratios
The purpose of this study was to examine the effect of charge ratio on the formation and properties of the chitosan (CS)-dextran sulfate (DS) nanoparticles developed for the delivery of water-soluble small and large molecules, including proteins. Rhodamine 6G (R6G) and bovine serum albumin (BSA) were chosen as model molecules. CS-DS nanoparticles were formul
