<abstract> <p>Viscosity of glucomannan (GM) needs to be modified support its application for spray drying encapsulation. The purpose this study was investigate degradation GM using cellulase that fulfills viscosity in a spray-dryer specification. This hydrolyzed (HGM) subsequently spray-dried encapsulating iron. Lower initial concentrations (0.5–1%) reached approximately 0.30 Pa·s w...

In this study, Cynara scolymus L. leaves aqueous extract powder was produced using a novel spray drying approach by incorporation of ongoing ultrasonic atomization and vacuumed drying chamber. A Response Surface Methodology (RSM)-based central composite face-centered design was employed for optimization of the operating conditions of the ultrasonic vacuum spray dryer. The independent variab...

Small particles are of great interest in a variety applications. Spray drying is common technique for particle synthesis, but it limited with respect to sizes below 10 μm. Therefore, new laboratory-scale spray dryer was designed address this issue. A novel aerosol generator consisting piezo crystal swirl chamber obtain droplets the low micrometer range. After and cooling, were deposited molten ...

In this study, the effect of some processing parameters on bulk density, particle density, particle size and some of powder reconstruction properties such as dispersibility, Wettability and water solubility index of spray dried barberry (Berberis vulgaris) juice powders were investigated. A Pilot Spray Dryer (Two- Flow nozzle, counter- current, one cyclone) was employed for the spray d...

Guaco (Mikania glomerata Sprengel) syrup is one of the most popular herbal medicines used to treat the symptoms of asthmatic bronchitis, cough and hoarseness. The coumarin 2H-1-benzopyran-2-one, is one of the major constituents of Guaco and contributes to its pharmacological effects. The pharmaceutical capsule form of dry extract of Guaco is recommended by the Brazilian Program of Medicinal Pla...
