The results showed (Table 5) that the level of these
elements decreased with reducing bran particle size possibly
because of the presence of more starchy materials in the
finer brans. The Fe+2 decreased from 0.026 to 0.016 %, Zn+2
decreased from 0.006 to 0.003 % and Ca+2 reduced from
0.080 to 0.046 % when particle size decreased from 1,200 to
90 μm.
