Electroseparation of chitosan oligomers by electrodialysis with ultrafiltration membrane (EDUF) and impact on electrodialytic parameters

Demineralization of soybean oligosaccharides extract from sweet slurry by conventional electrodialysis

“…Therefore these molecules could potentially migrate in electrical field towards the concentrate tanks through the membrane as demonstrated by Aider et al (2006Aider et al ( , 2008, which led to losses. Moreover, the high concentration gradient between the dilute and concentrate tanks, the Donnan transferring and accompanying effect (Cai, 2006) can also force them to permeate through the ion-exchange membrane and to transfer from the dilute tank to the concentrated one.…”

Facile method to manipulate the molecular weight and practical mass production of chitosan by mechanical shearing and concurrent ultrafiltration treatment

“…27 Electromigration rates of the chitosan oligomers were varied between 1.05 and 14.45% depending on the operating conditions (molecular weight cut-off (MWCO) of membrane and processing time). 28 A color change from light to dark yellow in the chitosan samples was observed after exposure to steam, and the intensity of the color change increased with increased heating time. 29 The color darkening of the heated chitosan may be attributed to the Maillard reaction.…”

Insertion of Filtration Membranes into Electrodialysis Stack and Its Impact on Process Performance

“…It is a hybrid process that combines conventional electrodialysis with electrophoresis principles using filtration membranes. Ultrafiltration membranes serve as molecular barriers inserted into electrodialysis chambers, whilst the electrical potential difference remains the separation driving force (not pressure difference) [1,2].…”

“…for separation of chitosan oligomers [1,6], cranberry juice enrichment by polyphenol antioxidants [7,8], separation of whey proteins [3], separation of bioactive peptides from alfalfa protein hydrolysate [9,10], soy protein hydrolysate [11] or snow crab protein hydrolysate [12,13].…”
