Abstract/OtherAbstract:
|
Metabolite production and antioxidant released during colonic fermentation of natural occurring dietary fibre (DF) from two European diets (Mediterranean and Scandinavian) were determined. With this aim, fibre DF and associated components were isolated from both whole diets, as well as from cereals and fruits-and-vegetables comprising the diets. DF was used as substrate for colonic fermentation in a dynamic in vitro model of the colon, samples were collected and fermentation metabolites were analysed. Statistical differences between samples were observed in the concentrations of short chain fatty acids, ammonia, and in the ratio acetate:propionate:butyrate. Whole grain cereal DF generated larger amount of propionate than refined flour cereal DF. Fruit-and-vegetable DF generated higher amounts of butyrate than cereal DF. Most antioxidant compounds were released from DF during in vitro colonic fermentation. It is concluded that different sources of DF may play a specific role in health maintenance mediated by metabolites produced during colonic fermentation. |
