It was tried to microencapsulate the ascorbic acid powder as a redox initiator with tripalmitin by use of the dry coating method. In the experiment, the feed ratio of the amount of tripalmitin to that of ascorbic acid, the coating time and the concentration of ethyl alcohol of pulverizing solvent were changed stepwise. The characteristics of microcapsules such as the content of core material, t...

The effects of cholesterol and Tween 80 on the physical stability of empty liposomes were investigated. Results showed that the physical stability of liposomes, including electrostatic and steric stability, was improved by addition of cholesterol and Tween 80. Liposomes prepared by different methods, thin-film hydration, thin-film sonication, reverse-phase evaporation and freeze-thawing, were t...

Microencapsulation of peptides and proteins has recently become a relevant alternative to develop novel drugdelivery systems. Among techniques designed to microencapsulate substances of different nature, the interfacial polymerization, spray-drying and solvent evaporation techniques are those most widely studied for encapsulation of biomolecules. The solvent double emulsion-evaporation procedur...

The aim of this study was to apply the external ionic gelation using an atomizing spray device comprised of a spray gun to improve the viability of Lactobacillus plantarum DKL 109 and for its commercial use. Three coating material formulas were used to microencapsulate L. plantarum DKL 109: 2% alginate (Al), 1% alginate/1% gellan gum (Al-GG), and 1.5% alginate/3% gum arabic (Al-GA). Particle si...

This study aimed to microencapsulate protein hydrolysates from stripped weakfish (Cynoscion guatucupa) industrial byproducts produced by Alcalase (HA) and Protamex (HP) spray drying, using maltodextrin as wall material. The physicochemical characteristics, in vitro antioxidant Angiotensin-I converting enzyme-inhibitory activities were evaluated during storage. Both microencapsulated showed sphe...

• Propolis (PROP) presents valuable health properties (e.g. antioxidant). PROP inclusion in foods is limited to its hydrophilicity, strong taste and aroma. Encapsulation may protect compounds mask unpleasant flavor extracts were encapsulated using alternative polymer-carriers loadings. efficiencies yields improved compared previous studies. Propolis, a heterogeneous matrix produced by honeybees...

We have tried to microencapsulate β-carotene with curdlan of a thermogelation type polysaccharide. Microcapsules were prepared by utilizing reverse dispersion, in which salada oil was the continuous phase (O') and the curdlan water slurry (W) was the dispersed phase. β-carotene (O) as a core material was broken into fine oil droplets in the dispersed phase to form the (O/W) dispersion. The (O/W...

The objective of this study was to microencapsulate the anti-inflammatory drug (naproxen) to provide controlled release and minimizing or eliminating local side effect by avoiding the drug release in the upper gastrointestinal track. Naproxen was microencapsulated with lipid-like carnauba wax, hydrogenated castor oil using modified melt dispersion (modified congealable disperse phase encapsulat...

Probiotics play an important role in human gut health. However, it remains a challenge to maintain the viability of probiotics throughout gastrointestinal transit. Hence, this study aimed microencapsulate Bifidobacterium lactis Bi-07 with galactooligosaccharides (GOS) using co-extrusion technique. Optimization calcium chloride (1.0% w/v 3.0% w/v) and GOS concentration 5.0% were performed encaps...

OBJECTIVE Human umbilical cord Wharton jelly-derived mesenchymal stem cells (hUCMS) are easy to retrieve in bulk. They may interact with immune cells by either cell contact or soluble factors. Little evidence is currently available on potential therapeutic application of hUCMS to systemic autoimmune disorders such as primary SS (pSS). We have recently developed an endotoxin-free alginate gel th...
