Calculating Total Dietary Fiber in Corn Flakes According to AOAC 985.29

Dietary fiber is a mixture of complex organic substances, including hydrophilic compounds such as soluble and insoluble polysaccharides and non-digestible oligosaccharides as well as a range of nonswellable, more or less hydrophobic compounds such as cutins, suberins and lignins. Total dietary fiber is determined using a combination of enzymatic and gravimetric methods. In this application note, total dietary fiber in cornflakes was calculated using VELP Scientifica’s GDE Enzymatic Digester and CSF6 Filtration Unit according to AOAC 985.29.
