Fatty acids and unsaponifiable matter composition of rice oil and rice germ oil as well as their dewaxed residue

Fatty acids and unsaponifiable matter composition of rice oil and rice germ oil as well as their dewaxed residue

Acta Agronomica Hungarica 41(1-2): 69-73

Gas liquid chromatography (GLC) technique was applied for determination of fatty acid and unsaponifiable matter composition of oils extracted from crude rice bran, crude rice germ and dewaxed oils. The results showed a resemblance in the fatty acid contents of each rice bran oil and rice germ oil with those of their dewaxed oils. The major fatty acids in all tested samples were palmitic (22.44-26.16%), oleic (34.37-38.46%) and linoleic (38.24-40-42%), whereas the minor were myristic (0.07-0.12%), stearic (0.29-0.51%) and linolenic (0.19-0.36%). Unsaponifiable matter composition showed that rice germ oil contains 20 compounds and its dewaxed oil contains 19 compounds. Twenty of these fractions were: 14 hydrocarbons, cholesterol, campesterol, stigmasterol, B-sitosterol, DELTA-5-avenasterol and DELTA-7-avenasterol. The major sterol compounds in rice germ oil and its dewaxed oil were B-sitosterol (50.39%), DELTA-5-avenasterol (19.04%), campesterol (13.58%) and stigmasterol (5.46%).
