Covalent and non-covalent interactions between polyphenols and polysaccharides produced vital consequences on the sensory and nutritive qualities of the many foods. In the present study, the structure dependence of the non-covalent interactions between phenolic acids (PAs) and an arabinan-rich
A water-soluble polysaccharide fraction was prepared from dehulled rapeseed meal (winter rapeseed variety Casino). Further purification yielded two major fractions having a high content of arabinose and galactose residues, with Ara/Gal ratios of 5.4 (G1) and 1.8 (G2). The Ara/Gal ratio of the high
The sorption capacity of arabinan-rich pectic polysaccharide (ARPP) onto ferulic acid (FA) was investigated using equilibrium dialysis assays. UV and FT-IR spectra showed that FA was successfully adsorbed by ARPP. The effects of temperature, pH, buffer concentration, NaCl, and ethanol on sorption
To enable structural characteristics of individual cell wall polysaccharides from rapeseed (Brassica napus) meal (RSM) to be studied, polysaccharide fractions were sequentially extracted. Fractions were analysed for their carbohydrate (linkage) composition and polysaccharide structures were also
Unprocessed and acid-extruded rapeseed meal (RSM) was fed to broiler chickens, with and without addition of commercial pectolytic enzymes. Nonstarch polysaccharide (NSP) fermentability and unfermented NSP structures from RSM were studied in the excreta in detail. From unprocessed RSM, 24% of the
