- Polysaccharides derived from plant foods are major components of the human diet, with limited contributions of related components from fungal and algal sources. In particular, starch and other storage carbohydrates are the major sources of energy in all diets, while cell wall polysaccharides are the major components of dietary fiber. We review the role of these components in the human diet, including their structure and distribution, their modification during food processing and effects on functional properties, their behavior in the gastrointestinal tract, and their contribution to healthy diets.

- The surface pressure–molecular area (–A) relationship for spread layers of the high molecular-weight glutenin subunit 1Dx5, a 58 kDa peptide derived from the central repetitive domain of the subunit, and an -gliadin fraction was measured by means of a surface film balance (Langmuir trough). The aqueous phase was a 10 mM acetate buffer, pH 4.0, either with or without 100 mM NaCl. Subunit 1Dx5 generated much higher surface pressures than the 58 kDa peptide, whereas the -gliadin fraction generally gave higher surface pressures than subunit 1Dx5. Furthermore, subunit 1Dx5, but not the 58 kDa peptide or the -gliadin fraction, formed a highly cohesive film. The differences in the interfacial behaviour of subunit 1Dx5 and the 58 kDa peptide were ascribed to significant hydrophobic interactions for the subunit. The reversibility of a compression–expansion cycle was generally greater for the second cycle than for the first. For subunit 1Dx5 and the -gliadins, but not the 58 kDa peptide, the reversibility was increased when NaCl was present in the aqueous phase.
