Purpose: To formulate the water in oil (W/O) emulsion of corn silk (CS) extract and to evaluate its stability at various storage conditions. Methods: Ethanol CS extract was prepared using maceration (cold) technique. A 4 % CS emulsion was prepared using varying concentrations of liquid paraffin, ABIL EM90 and water. The formulations were kept at 40 C for 28 days and to screen out the less stabl...

Pearled amaranth grains obtained by abrasive milling were processed by planetary ball milling to produce amaranth flours. The influence of milling energy on rheological and thermal behavior of amaranth flour dispersions and stability during 24 h storage at 4 °C were investigated based on a factorial design. The rheological behavior of flour dispersions (4 % and 8 % w/v) was determined using a r...

The solution properties of some cationic polyelectrolytes with ammonium quaternary centers either attached to an acrylic macromolecular chain (polycation PDMAEMQ type) or in the backbone (polycation PCA type) have been measured in order to identify how charge density, polyelectrolyte concentration, solvent polarity as well as temperature influence their behavior in solution by viscometric, cond...

Lead niobium zirconate titanate (PNZT) pastes with tailored rheological properties have been developed for direct-write fabrication of thick-film capacitor elements in highly integrated, multifunctional electroceramic devices. Such pastes exhibited pseudoplastic behavior with a low shear apparent viscosity of roughly 1 10 cP. On aging, the degree of shear thinning and the low shear apparent vis...

Ascorbic acid (AA), or vitamin C, is widely used in the pharmaceutical, cosmetic and food industries as an antioxidant and cosmetics containing AA have been gaining popularity in the last few years for the treatment of photoageing. To solve the problem of its low stability, some esters have been synthesised, such as magnesium ascorbyl phosphate (MAP), also available encapsulated in collagen-bas...

We have studied the extracellular polysaccharide (EPS) produced by the type strain, M8(T), of the halophilic bacterium Halomonas almeriensis, to ascertain whether it might have any biotechnological applications. All the cultural parameters tested influenced both bacterial growth and polysaccharide production. EPS production was mainly growth-associated and under optimum environmental and nutrit...

The development of a low glycemic index (GI) coconut milk ice cream by replacing 12% sucrose with different low GI sweeteners (xylitol, erythritol, inulin and fructose) was investigated. Three mixtures of sweeteners (6.2% xylitol + 7% inulin, 4% erythritol + 7% inulin + 2.15% fructose, 8.5% inulin + 5% fructose) were reformulated to obtain the similar characteristics as using 12% sucrose, inclu...

effects of some thermo-physical parameters on free convective heat and mass transfer over a vertical stretching surface at lowest level of heat energy in the presence of suction is investigated. the viscosity of the fluid is assumed to vary as a linear function of temperature and thermal conductivity is assumed constant. a similarity transformation is applied to reduce the governing equations i...

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...
