Variability in grain extract viscosity and water-soluble arabinoxylan content in wheat
1995
Saulnier, L. | Peneau, N. | Thibault, J.F.
Twenty-two varieties of wheat grown in France were analysed for their content of water-soluble arabinoxylans and the viscosity of their aqueous extracts. A high natural variation was observed in these two parameters [range 0.36-0.83% (w/w) dry matter and 1.24-2.28, for arabinoxylan content and relative viscosity, respectively]. The water-soluble arabinoxylans also exhibited a large variation in weight-average molecular weight as shown by size-exclusion chromatography and their intrinsic viscosities. The content of water-soluble arabinoxylans was only poorly correlated with the viscosity of the aqueous extracts.
