Relationship of physico-chemical structure of starch and digestibility on the lower gut. - AN0303

Selected starches (wheat, potato, rice and banana ) will be characterised chemically and physicochemically and their digestibility index determined in laboratory animals. These starches will then be subjected to varying temperature / hydration regimes which may be expected to induce a range of changes e.g. structural reorganisation short of gelatinisation, gelatinisation and subsequently retrogradation. These changes will be characterised biochemically and physicochemically and the resultant materials evaluated in both laboratory animals and human subjects at the medical school.
1. To examine the facility with which different starches form resistant sarch. 2. To examine the impact of processing conditions of temperature, hydration and rates of temperature change on the formation of resistant starch. 3. To examine the physical and chemical nature of the native starches or partially processed starches and that of the resistant starch. 4. To study the physiological/medical impact of resistant starch.
