A new ultra thbi filtration membrane has been used for 1eukoc.yte renrovul from eqythocyte concentrates. This filtration niembrane, an Aquanrarijrt Microsieve@, has a high pore density find N nurroiv pore size distribution and shows good sepuration behaviour. The low surfuce roughness of the niicrosieve will contribute to the biocontpatibility and will reduce cell rupture, in particulur!y hento...

sour cherry and orange juice were successfully cryoconcentrated. novel clarification (electro-flotation and ultra-filtration) improved cryconcentration efficiency. ef-uf clarified sour cherry and orange juices were cryoconcentrated in three stages up to 34.52±0.14, 44.42±0.19, 52.44±0.13 and 28.43±0.16, 40.51±0.15, and 45.42±0.19° brix at -10˚c respectively. duncan's multiple range test was use...

Two membrane electrochemical reactors (MER) were designed and applied to HLADH-catalysed reduction of cyclohexanone to cyclohexanol. The regeneration of the cofactor NADH was ensured electrochemically, using either methyl viologen or a rhodium complex as electrochemical mediator. A semi-permeable membrane (dialysis or ultra-filtration) was integrated in the filter-press electrochemical reactor ...

Peptides from soybean meal were subjected to extrusion and the effects of extrusion conditions, such as moisture of the materials, barrel temperature, screw speed and nozzle diameter, on the antioxidant properties were studied. The extrusion conditions that had the highest free radical-scavenging activity were further separated into three peptide fractions (using ultra filtration); hydrolysis o...

Date juice was treated by cross- flow ultra-filtration with molecular weight cut-off (MWCO) of 5 kDa. Optimized levels of feed brix, TMP and operation time were determined as 47.13, 82.11 psi and 30 min, respectively. Under such conditions, 80.94% decolourisation and 97.78 % turbidity reduction were obtained while loss of glucose and fructose were estimated to be only 3.49% and 9.62%, respectiv...
