Development and characterization of microcapsules containing Bifidobacterium Bb-12 produced by complex coacervation followed by freeze drying

Preparation and Characterization of Microcapsules Encapsulating Octyl Methoxycinnamate by Complex Coacervation

The aim of this study was to entrap the lipophilic ultraviolet absorber, octyl methoxycinnamate in microcapsuels to enhance its application. A complex coacervation method was established. Through the appearance of encapsulated glass beads prepared with different wall materials, gelatin and sodium polyphosphate were selected as wall materials because of dense structure and less adhesion. The eff...

effect of polymer concentration and acidification time on olive oil microcapsules obtained by complex coacervation

encapsulation of olive oil is an effective method to protect it against environmental deteriorative factors. in this research, olive oil microcapsules were produced by complex coacervation method. the objective was to examine the effect of gelatin and arabic gum as shell materials, lactose as cryprotectant, and different acidification times on microencapsulation efficiency of olive oil. arabic ...

Development of Multilayer Microcapsules by a Phase Coacervation Method Based on Ionic Interactions for Textile Applications

The present study describes the development of multilayer microcapsules by 11 alternate additions of chitosan (Chi) and sodium dodecyl sulfate (SDS) in a combined emulsification and phase coacervation method based on ionic interactions. After an alkali treatment, microcapsules are applied on polyester (PET) fabric by a padding process to investigate their wash-durability on fabric. Air atmosphe...

Viability of Bifidobacterium Pseudocatenulatum G4 after spray-Drying and Freeze-Drying

Viability of Bifidobacterium pseudocatenulatum G4 following spray-drying and freeze-drying in skim milk was evaluated. After spray-drying, the strain experienced over 99% loss in viability regardless of the air outlet temperature (75 and 85 °C) and the heat-adaptation temperature (45 and 65 °C, 30 min). The use of heat-adaptation treatment to improve the thermotolerance of this strain was ineff...
