Factors affecting mineral content of defatted rice bran

Abstract

Factors affecting mineral content in defatted rice bran. Four rice bran types with different stored
conditions were selected to determine major elements and trace elements including seven kinds of major
elements, sodium (Na), potassium (K), calcium (Ca), phosphorus (P), magnesium (Mg), sulphur (S),
chlorine (Cl). The trace iron(Fe) content was also determined when the EDS method used. Maximum amount
of mineral was found from defatted rice bran after milling within 24 hours( RB1 ), rice bran stored at
temperatures 5 O
C 2 days prior to extraction fat( RB3 ), rice bran storage at room temperature for 2 days
before being taken to extract fat ( RB2 ), Rice bran through the extraction of fat and protein( RB4 ),
respectively. The selected RB1 was determine mineral contents by standard methods ICP-OES to confirm
that the RB1 found Ca, Fe, P and Zn in amounts sufficient to bring into production a mineral supplement.
The result showed that, RB1 had P (6,300 mg/kg), Ca (322.391 mg/kg), Fe (126.876 mg/kg) and Zn
(38.199 mg/kg).
