The scope of the current study is to investigate the ultrafiltration process of high molecular weight β-glucan molecules with a final purpose to optimize their recovery from oat mill waste. Therefore, standard β-glucan solutions were processed in a dead-end cell using three types of membranes (regenerated cellulose, polyethersulfone and polysulfone) under several transmembrane pressures. Optimization was conducted by monitoring performance parameters and retention coefficients for each experimental combination. In terms of membrane type, polysulfone was selected as the most appropriate membrane material since it obtained satisfactory retention coefficient and performance parameter values when the β-glucan concentration was less than 600
mg/L. Thereafter, the polysulfone membrane was applied in a pilot cross-flow module instead of a dead-end cell. The retention of β-glucan as well as the flux recovery was markedly improved with no important reduction of the permeate flux. Finally, polysulfone membrane was applied in the pilot cross-flow module for the ultrafiltration of β-glucan containing feeds (<600
mg/L) recovered from the industrial oat mill waste. Results indicated that the optimized ultrafiltration process (polysulfone in cross-flow module, with transmembrane pressure ≤2
bar and β-glucan concentrations
<
600
mg/L) could be utilized in order to recover β-glucan from the oat mill waste feeds and clarify them from smaller organic and inorganic compounds. A disadvantage of the latter application was the small degree of separation between β-glucan and proteins.</description><identifier>ISSN: 0376-7388</identifier><identifier>EISSN: 1873-3123</identifier><identifier>DOI: 10.1016/j.memsci.2011.02.032</identifier><identifier>CODEN: JMESDO</identifier><language>eng</language><publisher>Amsterdam: Elsevier B.V</publisher><subject>artificial membranes ; Beta glucan ; beta-glucans ; cellulose ; Chemistry ; Colloidal state and disperse state ; Dietary fiber ; Exact sciences and technology ; General and physical chemistry ; inorganic compounds ; Macromolecules ; Membranes ; molecular weight ; monitoring ; oats ; Operational features ; Polysaccharides ; proteins ; Ultrafiltration ; wastes</subject><ispartof>Journal of membrane science, 2011-05, Vol.373 (1), p.53-63</ispartof><rights>2011 Elsevier B.V.</rights><rights>2015 INIST-CNRS</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c393t-ed598b252a366823df97a11c8e840798e0f1ca3749e2ac0f43b05014c12d65033</citedby><cites>FETCH-LOGICAL-c393t-ed598b252a366823df97a11c8e840798e0f1ca3749e2ac0f43b05014c12d65033</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,780,784,27923,27924</link.rule.ids><backlink>$$Uhttp://pascal-francis.inist.fr/vibad/index.php?action=getRecordDetail&idt=24099555$$DView record in Pascal Francis$$Hfree_for_read</backlink></links><search><creatorcontrib>Patsioura, Anna</creatorcontrib><creatorcontrib>Galanakis, Charis M.</creatorcontrib><creatorcontrib>Gekas, Vassilis</creatorcontrib><title>Ultrafiltration optimization for the recovery of β-glucan from oat mill waste</title><title>Journal of membrane science</title><description>► Ultrafiltration optimized for the recovery of β-glucan (>100
