2.3. Comparison of parboiled and raw rice bran
Freshly milled rice bran obtained from milling par boiled
paddy and raw paddy was used. Paddy is parboiled by soaking
in cold water for 72h followed by steaming for 10 min. The
steamed paddy is then solar dried and milled to remove the
husk. The bran obtained from milling of parboiled paddy was
used for extraction of oil. Oil was extracted using water and
hexane as solvents to determine the effect of parboiling of
paddy on aqueous and hexane extraction.
