In this study, new antimicrobial hydrogels were prepared via reaction of functionalized-tragacanthgum (TG) biopolymer by quaternary ammonium functionalization of TG (QTG) with acrylic acid(AA). Characterization of the QTG hydrogels (QTG-AA) was carried out by FTIR,thermogravimetric analysis (TGA), and 1H NMR. Dynamic mechanical analysis, (DMA) wasconducted to characteriz...

Various scaling methods such as relative viscosity, Peclet and Reynolds scaling were used to find the best scaling law. Scaling and modeling of the flow curves of various model emulsions consist of Tragacanth Gum (TG) (0.5, 1 % wt), Oleic acid (5, 10% v/v) and WPI (2, 4 % wt) were investigated and the best models were selected. As these emulsions are non-Newtonian, they do not obey the usual...

the aim of this research was to survey of using soy protein isolates and tragacanth gum as egg substitutes in mayonnaise formulation. the mayonnaise prepared with difierent compositions of soy protein isolate, egg, and tragacanth by applying the optimal mixture design method and effect of this substitution on its stability, heat stability, viscosity, texture, physicochemical and sensory charact...

The unique attributes, biodegradability, biocompatibility, perfect accessibility, and low production costs led to the use of natural gums in a different section our lives. Among them, we can mention obtained from microorganisms (xanthan gum gellan gum), plant tissues (Arabic tragacanth), seeds (konjac guar seaweeds (alginates, agar gum, carrageenans). Gums have essential applications medical ph...

Sustained release tablets of isoniazid were fabricated using guar gum and carbapol, Tragacanth Gum and PEG-6000, in different proportion and combinations by direct compression technique, Bulk density, tapped density, compressibility index, Hausner ratio before being punched as tablets. The tablets were evaluated for physical characteristic like hardness, weight variation, friability, and drug c...

Due to early deterioration of banana in drying process, almond, quince seed, and tragacanth gums as edible coatings were determined. For this purpose, banana slices were coated in 0.7% solution of each gum and one group remained uncoated as the control. The samples were examined at specific times considering the weight loss, color analyzing (a*, b*, and L*) through the method computer vision, c...

background: the excellent biocompatibility, biodegradability and biological properties of the hydrogels, fabricated using natural polymers, especially polysaccharides, are very advantageous for biomedical applications. gum tragacanth (gt) is a heterogeneous highly branched anionic polysaccharide, which has been used extensively in food and pharmaceutical industries. despite,  its desirable prop...

The natural tragacanth gum, the sap of Astragalus gummifer, has been successfully used as a gelling agent in tissue culture media for in vitro shoot development and proliferation of miniature rose and carnation. Shoot development of nodal segments excised from greenhouse grown plants, was investigated on MS medium solidified with either 2.5, 3.0, 3.5 and 4.0% tragacanth or 0.8% agar as control....

This study was undertaken to explore gum from Bombax buonopozense calyxes as a binding agent in formulation of immediate release dosage forms using wet granulation method. The granules were characterized to assess the flow and compression properties and when compressed, non-compendial and compendial tests were undertaken to assess the tablet properties for tablets prepared with bombax gum in co...
