We experimentally investigate the filament dynamics of non-Newtonian drops falling under gravity through air, and report the effects of semiilute concentrations of the polyelectrolyte polymer xanthan gum mixed in 80:20 glycerol/water with varying concentrations of potassium chloride KCl). We find that the addition of 780 ppm xanthan gum to the glycerol/water solvent dramatically increases the d...

The interest in polysaccharides has increased considerably in recent years, as they are candidates for many commercial applications in different industrial sectors like food, petroleum, and pharmaceuticals. Because of their costly production processes, industrial microbial polysaccharides like xanthan, dextran, curdlan, gellan, and pullulan constitute only a minor fraction of the current polyme...

Background Traditional vaccines (killed or inactivated) played vital roles in controlling and eradicating infectious diseases for a long time. Antigen-specific T cell response can be induced when mice are intramuscularly inoculated with naked plasmid DNA. Therefore, DNA vaccines were evaluated in many studies, demonstrating its safety, stability and easy production. Furthermore, it has been rep...

Increasing oil consumption in Indonesia encourages an improvement of production using chemical flooding Enhanced Oil Recovery (EOR) technology. Chemical is injection method materials based on polymer and nanoparticles such as α-Fe2O3-xanthan gum nanocomposite into the reservoir. In this study, α-Fe2O3 were synthesised then blended to xanthan by sonochemical through ex-situ process. The X-ray di...

A chemical derivative of xanthan gum polysaccharide is investigated as a new artificial matrix for the encapsulation of chondrocytic cells. Toward this goal, a novel micro-droplet generator is developed to produce microcapsules. Microcapsules with an average diameter of 500 µm, smooth surface, and homogeneous size distribution are obtained. ATDC5 cells encapsulated in carboxymethyl xanthan (CMX...

The aim of this study was to investigate the influence of pH, buffer species and ionic strength on the release mechanism of chlorpheniramine maleate (CPM) from matrix tablets containing chitosan and xanthan gum prepared by a hot-melt extrusion process. Drug release from hot-melt extruded (HME) tablets containing either chitosan or xanthan gum was pH and buffer species dependent and the release ...

This study was aimed to find the formulation of composite flours from rice, cassava, and soybean flours, potato starch, and hydrocolloids, and also to find the egg replacer formulation from whey and soybean protein isolate. The composite flours and egg replacer then were used as wheat flour and egg alternatives in cake production, and some physicochemical and functional properties of the treate...
