© 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.Summary Enhancement of the extraction rate of β-glucan from corn pericarp (CP) by repeated freeze-thaw treatment of 2% w/w NaOH-6 M urea solution was investigated with emphasis on the association of β-glucan with cellulose in CP. Three freeze-thaw cycles were found to be adequate for extraction of β-glucan at a rate of 97.8%. The increase in extraction rate induced by the freeze-thaw treatment was estimated to be approximately 20%. The natural cellulose I structure of the cellulose in CP was disrupted by the freeze-thaw treatment, suggesting that the increase was due to greater β-glucan solubilization owing to the disruption of its association with cellulose by hydrogen bonds. The applicability of the present technique to other cereals was also demonstrated; extraction rates of 82.8% for oat meal and 92.5% for barley flour were achieved.
