Membrane applications in functional foods and nutraceuticals

17-06-2011 | Oguz Akin; Feral Temelli; Sefa Koseoglu, Critical Reviews in Food Science and Nutrition, 2011

Abstract The functional foods and nutraceuticals market is growing at a rapid pace. Membrane processing offers several advantages over conventional methods for separation, fractionation and recovery of those bioactive components. In this review, membrane applications of lipid-, carbohydrate-, and ...

MODELING OF HEAT AND MASS TRANSFER IN A ROTATING VERTICAL POROUS CHANNEL WITH HALL CURRENT

09-06-2011 | Sahin Ahmed; Joaquín Zueco, Chemical Engineering Communications, 2011

In this study we have obtained an exact solution to the problem of heat and mass transfer in a rotating vertical porous channel taking into account the effects of Hall current. A strong magnetic field of uniform strength is applied along the axis of rotation. The entire system rotates about the ...

EFFECT OF pH AND IONIC STRENGTH ON COMPETITIVE ADSORPTION OF ERYTHROMYCIN A AND C ONTO MACROPOROUS RESIN SEPABEAD SP825 AT DIFFERENT TEMPERATURES

09-06-2011 | Zhu Sheng; Zhu Jia-Wen; Chen Kui, Chemical Engineering Communications, 2011

Equilibrium adsorption experiments were carried out to investigate the effect of pH and ionic strength on competitive adsorption of erythromycin A (EA) and C (EC) in aqueous solution onto macroporous resin, Sepabead SP825, at different temperatures. The equilibrium data for the binary system were ...

Effect of Bath Concentration on Coagulation Kinetics at the Early Stage during Wet Spinning of PAN Copolymer Nascent Fibers

20-05-2011 | Pucha Zhou; Chunxiang Lu; Jiyou Shi; Kaixi Li; Fu He; Shouchun Zhang; Yonghong Li, Journal of Macromolecular Science, Part B, 2011

A mathematical model was proposed to simulate the effect of bath concentration on coagulation kinetics at the early stage of wet spinning for the poly(acrylonitrile-co-vinyl acetate)/dimethylsulfoxide (DMSO)/water system. The dependence of critical precipitation time, components concentration ...

Bounded soft-sphere fluids by molecular dynamics and integral equation techniques

29-04-2011 | G. Rickayzen; D.M. Heyes, Molecular Physics, 2011

The structural properties are determined for fluids composed of particles interacting with the Bounded Soft-sphere (BSS) potential, V(r) = εσ 2 n /(a 2 + r 2) n , where a is a variable parameter, r is the separation between the particle centres, n is an integer exponent, and ε and σ, ...

Crystal nucleation in binary hard-sphere mixtures: the effect of order parameter on the cluster composition

29-04-2011 | Ran Ni†; Frank Smallenburg†; Laura Filion; Marjolein Dijkstra, Molecular Physics, 2011

We study crystal nucleation in a binary mixture of hard spheres and investigate the composition and size of the (non)critical clusters using Monte Carlo simulations. In order to study nucleation of a crystal phase in computer simulations, a one-dimensional order parameter is usually defined to ...

Adsorption Behavior of Methylene Blue from Aqueous Solution by the Hydrogel Composites Based on Attapulgite

26-03-2011 | Yi Liu; Wenbo Wang; Yeling Jin; Aiqin Wang, Separation Science and Technology, 2011

A series of carboxymethyl cellulose-g-poly (acrylic acid)/attapulgite hydrogel composites were synthesized for the removal of cationic dye methylene blue. Various factors affecting the uptake behavior were investigated. Adsorption rate of the hydrogel was quite fast, and adsorption equilibrium ...
