Abstract Kuini powders were obtained through spray-drying, freeze-drying, vacuum oven drying and convection drying. Colour, water activity (Aw), moisture content, hygroscopicity, wettability, flowability, degree of caking, solubility index (WSI), total colour change, phenolic content carotenoid determined compared. Convection resulted in the highest yield (46.97%), (4.91%), Aw (0.55) WSI (74.33...

R a Drying is a frequently used technological process that has found its use in almost every industry branch. It is a physical process where heat impact influences the lowering of material's moisture, without changing its chemical properties. Drying is one of the basic processes in production of ceramic products. Granulate is generated as a final output product after drying of the mixture of wa...

Instant food powders are usually produced by spray drying of formulated liquid and powder agglomeration, either into the drying chamber or in an external fluid bed. During spray drying, according to the liquid composition, the viscosity of the initial liquid drops increases more or less rapidly, until the drop surface reaches a rubbery state considered as sticky, before further drying. This sti...

      The first aim of the present investigation was to prepare solid dispersions to improve the dissolution properties of oxcarbazepine and quetiapine using PEG 6000 as a carrier with the help of two methods of preparations viz. spray drying and modified solvent method, and to compare the two methods. The second objective was to apply the modified solvent method for preparation of sustained re...

Novel advanced spray-dried and co-spray-dried inhalable lung surfactant-mimic phospholipid and poly(ethylene glycol) (PEG)ylated lipopolymers as microparticulate/nanoparticulate dry powders of biodegradable biocompatible lipopolymers were rationally formulated via an organic solution advanced spray-drying process in closed mode using various phospholipid formulations and rationally chosen spray...

the goal of this research is preparation, optimization and in-vitro evaluation of rifampin-loaded silica nanaoparticles in order to use in pulmonary drug delivery. nanoparticles are exhaled because of thier small size, preparation of nanoaggregates in micron-sized scale and re-disrpersion of them after the deposition in the lung is one approach in order to overcome this problem, which we used i...

here we report a novel approach for preparation of a 6-day transdermal drug delivery system (tdds) as treatment for mild to moderate alzheimer’s disease. the spray drying method was used to prepare microparticles containing the anti-alzheimer drug. the content of the drug was determined by high performance liquid chromatography (hplc) method. the morphology and size range of the microparticles ...

the objectives of present investigations were to optimize concentration of oil, surfactant and cosurfactant by pseudoternary phase diagrams and to develop a stable formulation of self emulsifying drug delivery system (sedds) in order to enhance the dissolution rate of poorly soluble irbesartan (ibs) by sedds. pseudoternary phase diagrams were constructed to identify the self emulsifying region....

OBJECTIVES The objective of this work was to spray dry p-aminosalicylic acid (PAS) and its ammonium salt and to investigate the impact of the pore-forming agent, ammonium carbonate (AC), on the morphological, aerodynamic and physicochemical properties of the resulting powders. METHODS Microparticles were prepared by spray drying from ethanol/water solvent systems. Their solid-state properties...
