Five different varieties of paddy (four pigmented and one non-pigmented) were shelled and milled in
pre and post parboiled form, their dietary fiber contents were estimated. Under similar conditions of
milling, raw rice showed a high degree of polish (DOP), 9e12 g/100 g and parboiled rice showed low
DOP, 4.6e6.6 g/100 g. Dietary fiber content was high in pigmented rice, 9e10 g/100 g compared to nonpigmented,
w6 g/100 g. Soluble fiber content in pigmented head rice (dehusked) varied from 1 to 1.5 g/
100 g and in its brokens varied from 0.45 to 1.45 g/100 g. Dietary fiber content was low by about 1% in
parboiled rice. In the parboiled rice of pigmented varieties, the total fiber content varied from 7.95 0.15
to 9.05 0.25 g/100 g and the soluble fiber content varied from 0.7 to 0.9 g/100 g. In milled parboiled
rice the respective values were 5 0.4 to 6 0.1 g/100 g and 0.85 0.05 to 1.25 0.05 g/100 g.
However, the soluble fiber content in the non-pigmented brown rice, IR-64 remained same after parboiling,
0.75 0.5 g/100 g. Milled parboiled rice showed higher soluble dietary fiber compared to milled
raw rice. In conclusion, dietary fiber was high in pigmented rice varieties when compared with nonpigmented
rice.
