Insoluble and soluble non-starch polysaccharides (NSPs) were analyzed by gas chromatography (VARIAN, CP-3800, Walnut Creek, CA, USA) as the alditol acetate derivatives of monosaccharide based on the method developed by Englyst and Hudson (1993), and Theander and Westerlund (1993).
Individual neutral sugars were analyzed as their alditol acetates by gas-liquid chromatography (GLC) using an HP 5890 SII with FID system, equipped with a capillary column (025 mm [empty set] x 30 m, model B-210, with film 0.

Total, soluble and insoluble NSP and their constituent sugars were determined as alditol acetates by gas-liquid chromatography for neutral sugars, and by a colorimetric method for uronic acids using a modification of the Uppsala method (Theander et al.
