RESUMO
The objective of this study is to review the compliance of fatty acid compositions of Thai and India rice bran oil and level of desmethylsterols of Thai crude rice bran oil with the Codex Standard for Named Vegetable Oil (Codex Stan 210-1999). Fatty acid compositions of 90 samples of Thai and India refined rice bran oil were analyzed by capillary gas liquid chromatography. The results indicated that the contents of the C14:0, C18:2, C22:0 and C24:0 possible fall outside the range of Codex Stan 210-1999. In addition, sterol profile content of 40 samples of crude rice bran oil from Thai refinery plants were studied. The test results of major compositions of desmethylsterols are in good agreement with CODEX STAN 210-1999 except for Brassicasterol and other desmethylsterols. Accordingly, these data were proposed to corporate into the codex standard. Consequently, Codex agreed to amend the fatty acid composition of C14:0, C18:2, C22:0 and C24:0 from ND to 1.0, 21 to 42, ND to 1.0 and ND to 0.9 % and broaden level of Brassicasterol and other desmethylsterols to "ND-0.3" and to "7.5-12.8" accordingly.
