conclusions in conclusion, the suspension containing veegum 1%, sodium carboxy methyl cellulose 1%, glycerine 0.2%, sodium citrate 0.3% and sorbitol 20 % was chosen as the most physically stable formulation. results according to the results, glycerin (0.2%) and sodium citrate (0.3%) had the best effect on the suspension stability as wetting and flocculating agents, respectively. rheological pro...

Media composition and culture conditions for levan production by Bacillus mojavensis (BM-levan) were optimized using Plackett–Burman Box-Behnken designs. The yield was 0.44 g of per gram sucrose consumed. decomposition revealed an optimal temperature 228 °C, endothermic peak at 216.58 °C a melting enthalpy 49.28 J/g. rheological parameters the aqueous solutions from BM-levan determined accordin...

in this study, tretinoin microemulsion has been formulated based on phase diagram studies by changing the amounts and proportions of inactive ingredients, such as surfactants, co-surfactants and oils. the effects of these variables have been determined on microemulsion formation, particle size of the dispersed phase and release profile of tretinoin from microemulsion through dialysis membrane. ...

The effects of milling energy (0.26–4.08 kJ/g) on starch structure, flow behavior and syneresis dispersions (4–8% w/v) were investigated. Crystallinity loss (XRD analysis) during could be mathematically related with the increase 1047 cm?1/1022 cm?1 FT-IR intensity ratio (Ri) it was also reflected by changes in shape surface roughness granules (SEM micrographs). Starch showed a Newtonian or pseu...

smp was substituted by wpc in four levels for preparing reconstituted milk. two ropy and one nonropy starter cultures was used for doogh preparation. yield stress, viscosity, consistency index and pseudoplastic behavior of doogh increased by increasing wpc content. results showed that wpc increased colloidal particles dimension and constructed a network which led to a decrease in doogh phase se...

23 The rheological and functional properties of gelatin from the skin of bigeye 24 snapper (Priacanthus hamrur) fish were assessed. The protein content of dried gelatin 25 was 94.6% and moisture content was 4.2 %. The amino acid profile of gelatin revealed 26 high proportion of glycine and imino acids. The bloom strength of solidified gelatin was 27 108 g. The average molecular weight of fish s...

This study investigates the effects of micro- and nano-sized SiC powder on the rheological behavior of Al based feedstocks for powder injection molding (PIM).  Different compositions of Al feedstocks with additions of micro and nano-SiC powder were prepared and their rheological properties were measured with a rotational rheometer. The effects of SiC content and shear rate were investigated and...
