文摘
- •
NMR shows dynamic molecular interactions between bile salts and cereal soluble fibres.
- •
Chemical shift changes due to concentration or dilution of bile in presence of fibres.
- •
Line broadening of bile resonances in presence of some fibres suggesting entrapment.
- •
Bile salt induced conformation changes for β-glucan but not arabinoxylan from SAXS.
