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 ability of pea protein isolates (PPI) to form complex coacervates with tragacanth gum was investigated. coacervate formation structurally compared three other PPI-polysaccharide interaction models: arabic and sodium alginate (known PPI) tara gum, a galactomannan. effects the pH protein/polysaccharide ratio were mainly investigated using turbidity zeta potential measurements. Regarding solub...

The impact of natural emulsifier type on the fabrication, stability, and release attributes water-in-oil-in-water (W/O/W) emulsions prepared with a high-shear mixer were investigated: gum arabic, high-methoxy pectin, whey protein isolate (WPI), soy (SPI). At 1 wt%, all emulsifiers produced W/O/W similar mean droplet diameters (d32 = 23–25 ?m). However, less pectin was required to form small dro...

The mechanical and disintegration properties of paracetamol tablets formulated using Delonix regia seed gum (DRSG) as a binder have been studied in this work. Acacia BP (ACG) and tragacanth BP (TRG) were used as official gum standards. The mechanical properties, i.e. tensile strength (TS) and brittle fracture index (BFI), showed that with an increase in concentration of the gum binder, the tens...

AgNPs-Tragacanth conjugate gel as an eco friendly and low cost membrane was applied for the effective electromembrane extraction (EME) of Tenofovir disproxil fumarate, an important acidic and high polar (log p=1.25) antiviral drug, followed by HPLC-UV determination. The effect of various parameters on the extraction efficiency including the presence of AgNPs, tragacanth gum concentration, gel t...

Food powders were applied on crackers that had been coated using water, oil, emulsion, sucrose, or hydrocolloid solutions. The hydrocolloids that were used include gellan gum, kappa-carrageenan, methylcellulose, gum karaya, gum tragacanth, gum arabic, guar gum, modified starch, and maltodextrin. Solutions of similar hydrophobicity to the powder gave the greatest adhesion. NaCl, barbecue (BBQ), ...

background: the dispersed phase volume fraction plays key role in oil-in-water emulsion stability by different mechanisms like partial flocculation, depletion flocculation and bridging flocculation. since the mentioned mechanism is affected by emulsifier concentration presented in system, the major aim of this study was to investigate the effect of dispersed phase volume fraction on physical st...
