Total Dietary Fiber - Enzymatic assay kit
Reference : K-TDFR
See General Referee Reports: Journal of AOAC INTERNATIONAL, Vol. 81, No. 1, 1998.
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 non-swellable, more or less hydrophobic, compounds such as cutins, suberins and lignins.
The procedures for the determination and analysis of total dietary fiber as outlined in the data booklet are based on the methods of Lee et al.1 and Prosky et al.2,3 (AOAC 991.43, AOAC 985.29, AACC 32-07.01 and AACC 32-05.01).
However, the enzymes in this Total Dietary Fiber Kit can also be used in other dietary fiber analytical methods such as AACC Method 32-21.01 and AACC Method 32-06.01.
