Rice bran is known to contain oil, it is known to be the most important by –product
that is used for animal feeding. It is
otabined by passing dehulled grain between gabrassive cone or disces and the different grades of grain
obtained from cone or disc gap settings
are generally mixed/. Rice bran usually
contains about 140-180g/kg of oil Osiji
(2006) in hamsters addition of the diet of 10 percent dietary fibre from stabilized rice bran
and oat bran significantly reduced the animals plasma
cholesterol compared to the
control Kahlom et al. (1990).
In
repeat experiment only defatted bran and oat bran lowered the cholesfrol level. (Haumann, 1989).
Heat stabilized
rice bran providing7 percent dietary fibre lowered the cholesfrol
and surpassed wheat bran when
combined with 5 percent fish oil in lowering
plasma and hepatic triglyceride and hepatic lipogenesis Topping et al, 1990) the hyocholesterolanic effect of oat bran is due to its
high content of soluble hemicelluoses. By
contrast the hypocholesters laenic activity of rice bran oil in human
and rats Raghuran, (1989) is due to the unsaponifiable matter
fraction(Suzuki et al, (1962) Sharama and
Rukumini (1988,1987). Rice
bran oil lowered human
blood chloestrol more effectively than did sunflower, corn
and safflower oils Suzuki et al,
(1962).
