2. Optimization of the conditions for producing water-in-oil-in-water microemulsions and spray-dried microcapsule of tomato extract powder
Abstract The objective of this study was to investigate optimized conditions for producing water-in-oil-in-water (W/O/W) microemulsions and spray-dried microcapsules of tomato extracts. The condition of highest yield for W/O/W microemulsification was optimized by response surface methodology (RSM). The independent variables were ratio of tomato extract to M

3. Effects of bone morphogenetic protein-2 (BMP-2) and vascular endothelial growth factor (VEGF) release from polylactide-poly (ethylene glycol)-polylactide (PELA) microcapsule-based scaffolds on bone
Multiple growth factors can be administered to mimic the natural process of bone healing in bone tissue engineering. We investigated the effects of sequential release of bone morphogenetic protein-2 (BMP-2) and vascular endothelial growth factor (VEGF) from polylactide-poly (ethylene glycol)-polylactide (PELA) microcapsule-based scaffolds on bone regeneratio

4. Microencapsulation of plum (Prunus salicina Lindl.) phenolics by spray drying technology and storage stability
Abstract To improve the stability of the phenolic extracts from plum fruit (Prunus salicina Lindl.), the microencapsulation conditions of spray drying were optimized by the response surface method. The Box-Behnken experimental results indicated the optimal conditions involved an inlet air temperature of 142.8 °C, a core material content of 23.7% and a feed

5. Differential Scanning Calorimetry study on curing kinetics of diglycidyl ether of bisphenol A with amine curing agents for self-healing systems
ABSTRACT Epoxy resin is one of the most important polymeric matrixes for diverse uses, such as aeronautical, mobile, electronics and others. Providing a material capable of self-healing microcracks will allow it to have a more reliable and longer use. In order to study this new property of self-healing to an epoxy resin, a Differential Scanning Calorimetry (

6. An effective device for generating alginate microcapsules
An alternative approach to somatic gene therapy is to deliver the therapeutic protein by implanting genetically modified cells that could overexpress the gene of interest. Microencapsulation devices were designed to protect cells from host rejection and prevent the foreign cells from spreading while allowing protein secretion. Alginate microcapsules form a s

7. Synthesis of mesoporous silica microsphere from dual surfactant
A new procedure is reported to synthesis mesoporous silica micro sphere for the first time. In these method two surfactants namely Span 80 and Tween 80 were used. Small angle X ray diffraction and N2 adsorption analysis shows the synthesized material has mesoporous property. The material has spherical morphology with 1-10 µm particle size. Beside the materi

9. Polymeric microcapsules poduction from sodium alginic acid for cell therapy
Development of polymeric materials has been increasingly emphasized in Biomedicine. Here, we evaluate the use of microcapsules made of Biodritin®, a biocompatible polymer compound which contains sodium alginic acid, a natural polymer extracted from algae, and Cis-Chondroitin sulfate, a glycosaminoglycan from the extracellular matrix. Gelation of this polyme

10. 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

11. Preparo, caracterização e avaliação funcional de microcapsulas obtidas por spray drying, contendo extrato de cafe crioconcentrado. / Preparation, charaction and funcional evaluation of microcapsules obtained by spray drying, containing cryoconcentrated coffee extract.
Microencapsulation using spray dryer has been widely used in food industry, seeking core protection. Nowadays, the gum arabic and maltodextrin have been used as wall material, but cashew gum was still not studied as a microcapsule for this purpose. This way, the objective of this work was studied the volatile retention of coffee extract during microencapsula

12. Preparo e caracterização de microcapsulas obtidas por polimerização ionica para alimentação de larvas de peixe / Preparation and characterization of microcapsules obtained by polymerization Ionica feeding of fish larvae
This research aimed at producing microcapsules capable of retaining proteins, with the objective of substituting the live organisms used in larval fish feed. Four different polysaccharides: alginate, carrageenan, gelan gum and pectin were used, all having the capacity to form gels by ionic polymerization both individually and in association, in order to prod
