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...

introduction : one of the most important problems of synthetic packaging of materials had been the time consuming process of their decomposition. therefore, they have the potential to contaminate the environment. during the recent years, the above-mentioned problem has paved the way for developing biodegradable biopolymers. one group of these polymers is films and edible coatings. soy protein i...

The effects of different hydrocolloids on the gelatinisation behaviour of hard wheat flour were investigated. Influence of guar, xanthan, Arabic, carboxy methyl cellulose (CMC) and tragacanth gums on wheat flour was studied using micro viscoamylograph. It was found that all hydrocolloids except tragacanth greatly modified the gelatinisation properties of wheat flour. Guar and xanthan significan...

XGH (xylogalacturonan hydrolase; GH 28) is an enzyme that is capable of degrading XGA (xylogalacturonan), which is a polymer of alpha-D-galacturonic acid, highly substituted with beta-D-xylose. XGA is present in cell walls of various plants and exudates, such as gum tragacanth. XGA oligosaccharides were derived from an XGH digestion of gum tragacanth, then fractionated, and analysed for their s...
