Chemical and physiochemical properties of cell-wall biopolymers in relation to lipid absorption and metabolism - AN0104

The project represents a novel multidisciplinary approach to the understanding of the effects of dietary fibre on the human digestive processes. In particular, non-starch PS comprising cell walls will be studied after cooking and processing, to mimic the form in which they are usually eaten. The work spans 3 areas; Area 1, which examines the effects of cooking and processing on cell wall architecture in relation to the physicochemical behaviour of foods during gastrointestinal transit; Area 2 examines the effects of NSP on the emulisification and absorption of lipids in vitro; and Area 3 focuses on the physiological effects of NSP on the rate and site of lipid absorption in vivo.
1. To correlate the chemical and physiochemical properties of NSP (Area 1) with: a) the emulification and subsquent micellisation processes (Area 2). b) its effects on nutrient availability and interactions in vivo (Area 3). 2) To consolidate the in vitro results on the interactions of NSP with lipids (Area 2), with the data generated in vivo on the physiological effects of cell wall preparation ( Area 3). 3) To perform predictive modelling of NSP behaviour in rel ation to interaction with nutrients (particularly lipids) in the diet, and disseminate results.
