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, si...

Proteins and polysaccharides are common ingredients in food products. In many food formulations, proteins and polysaccharides (two major biopolymers) are used simultaneously. Understanding their interactions can help controlling physical properties and stability of formulated foods. Interactions between β-lactoglobulin (BLG) and tragacanth gum (TG) were studied in aqueous solutions at pH rangin...

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 measurements were al...

Date syrup as a nutritional additive and safe alternative to added sugar is one of the best choices for milk flavoring. In this study, a flavored milk beverage was formulated using date syrup for flavoring the product and gum tragacanth to obtain an acceptable mouth feel. Steady shear and dynamic oscillatory rheological properties of the samples contained 3 concentrations (0, 0.1, 0.2, and 0.3%...

INTRODUCTION Mechanical trauma to the nasal mucosa increases the risk of synechia formation, especially after chronic rhinosinusitis and nasal surgeries. OBJECTIVE This study was carried to assess the effect of propolis administration in healing injured nasal mucosa in rats. METHODS We randomly divided eighteen rats into three equal experimental groups: (1) non-treated group; (2) gum tragac...

Gum tragacanth is a natural complex mixture of polysaccharides and alkaline minerals extracted from species of Astragalus plant, which is found widely in arid regions of the Middle East. In a pilot experimental study we examined the effects of its topical application on wound healing in ten albino adult male rats. Two similar parasagittal elliptical full-thickness wounds (control vs. test sampl...

The present study was undertaken to develop oral sustained release tablets of metoprolol tartrate using natural hydrophilic matrix formers (xanthan gum and tragacanth). Sustained release matrix tablets of metoprolol tartrate were prepared by using different ratios of drug, xanthan gum and tragacanth. Microcrystalline cellulose (MCC) was used as diluent. The polymer was incorporated into a matri...

Background & Aim: Tragacanth is a natural gum obtained from the dried sap of several species of Middle Eastern egumes of the genus Astragalus, that is a viscous, odorless, tasteless, water-soluble mixture of polysaccharides. Tragacanth is used in pharmaceutical and foods industries as an emulsifier, thickener, stabilizer, and texturant additive. Sponge cake is one of the most popular b...
