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...

In present study, two kinds of thermal power plant ashes; one the fly ash and the other waste ash are mixed with adhesive tragacanth and cement to produce new composite materials. 48 new samples are produced by varying the percentages of the fly ash, waste ash, cement and tragacanth. The new samples are subjected to some tests to find out their properties such as thermal conductivity, compressi...

Removal of antibiotics from contaminated water is very important because their harmful effects on the environment and living organisms. This study describes preparation a bionanocomposite carboxymethyl tragacanth gum-grafted-polyaniline γFe2O3 using an in situ copolymerization method as effective adsorbent for amoxicillin antibiotic remediation polluted water. The prepared materials were charac...

Persimmon fruits are often affected by large postharvest losses due to rapid ripening and the early onset of senescence. To reduce such in fresh fruits, application hydrocolloid-based edible coatings was conducted. Therefore, a plant gum, tragacanth gum (TCG), applied persimmon at 0.5%, 1%, 1.5% TCG concentrations, stored 20 ± 2 °C 80–85% relative humidity for days (analysis 0, 4th, 8th, 12th, ...

ABSTRACT: This paper presents the results of studies concerned with the preparation of fresh food foams based on egg white and various hydrocolloids including Iranian gum tragacanth, guar and xanthan gums at different concentrations (0.002-0.040% w/w). The basic physical parameters of the obtained foams such as overrun, stability and morphology of gas bubbles were measured. Viscosity measuremen...

Keratin protein has been applied for biomedical applications due to its biocompatibility, biodegradability, mechanical resistance, and bioavailability. Tragacanth gum (TG) as a polysaccharide-based biopolymer wound healing antimicrobial properties. In this study, keratin was extracted from protein-based chicken feather by using reduction hydrolysis (sodium sulfide), nanogels of TG composites at...
