Mn, Zn, Cu and Fe in total (TDF), soluble (SDF) and insoluble (IDF) di
etary fiber residues of four different samples of peas were measured.
The offical AOAC method was used to determine the TDF, SDF and IDF, an
d mineral content in the fiber residues was assayed by flame atomic ab
sorption spectrophotometry. A considerable amount of ash was associate
d with TDF and SDF. The mineral association with TDF complex was consi
derable for Mn and Fe, moderate for Zn and negligible for Cu, although
the mineral association differed as a function of dietary fiber fract
ion. A high percentage of Mn and Zn content in peas was associated wit
h SDF, and Fe with IDF.
