Dear all,

we are working on determination  of  dietary fiber by Prosky method. It says that after enzymatic treatment, weigh the residue and calculate the difference by subtracting ash and protein.

Do we need to determine ash and protein of residue after all enzymatic treatments or it is fine to subtract protein and ash values obtained for whole food?

Thank you in advance.
