| Popis: | Water-extractable arabinoxylan (WEAX) gels exhibiting different structural, rheological and protein transport properties were obtained upon laccase treatment of WEAX solutions, by modifying (i) the initial ferulic acid (FA) content of WEAX from 2.3 to 1.6 mg/mg AX or (ii) the AX concentration of the WEAX solution from 0.5 to 2.0% (w/v). WEAX gels with di and tri-ferulic acid (di-FA, tri-FA) contents varying from 6.2 to 3.2 mg/ml gel and from 0.61 to 0.27 mg/ml gel, respectively, were obtained. In parallel, increases in gel mesh sizes from 201 to 331 nm and reduction of G 0 of gels from 160 to 12 Pa were observed. The differences in structural and rheological characteristics of WEAX gels were reflected in their capacity to load and release proteins of Mw ranging from 43 to 669 kDa. The possibility of modulating protein release from WEAX gels makes these gels potential candidates for the controlled delivery of proteins. q 2005 Elsevier Ltd. All rights reserved. |
