How do you measure fibre?
Dietary fiber is calculated as the weight of the residue minus the weight of the protein and ash, reported as a percentage of the original sample weight.
What is the most useful method for determining the chemical composition of a Fibre?
Van Soest
You can search for the Van Soest method to determine the biochemical composition (this is a very common method).
What are 4 ways that the physical characteristics of a fiber can be examined?
Fibers are analyzed using burn tests, tests for solubility in different solutions, polarized light microscopy, or infrared spectroscopy.
