Composition of waxes from crude rice bran oil

Abstract: Hard and soft waxes were separated from the tank settling of crude rice bran oil by solvent extraction and analyzed for their composition by gas liquid chromatography (GLC). The results showed that the melting points of the hard wax and the soft wax were 79.5 C and 74 C, respectively, and that the hard wax was mainly composed of saturated fatty alcohols of C24, C26 and C30, saturated fatty acids of C22, C24 and C26, andn-alkanes of C29 and C31. The soft wax was mainly composed of saturated fatty alcohols of C24 and C30, saturated fatty acids of C16 and C26, andn-alkanes of C21 and C29. In the soft wax, lauric acid was also detected.

Concentration of tocopherols and tocotrienols from vegetable oil

Abstract: PURPOSE:Tocopherol and tocotrienol in vegetable oil are concentrated by extracting the vegetable oil with a specific solvent and distilling off the solvent, whereby the concentration is economically and efficiently conducted by simple operations. CONSTITUTION:Vegetable oil containing tocopherol and tocotrienol such as palm oil, rice bran oil or soybean oil is extracted with a solvent of a monohydric lower alcohol or a mixture thereof with a ketone. The amount of the solvent used is 20- 80pts.vol., preferably 40-50pts.vol. per 100pts.wt. of the oil. Then, the extraction mixture is stood and separated into one phase soluble in the extraction solvent and the other phase soluble in the coil. The solvent-soluble phase is distilled to obtain the objective concentrate as a distillation residue. Since this process does not contain chemical reactions such as esterification or saponification, the oil is not damaged and the separation is readily effected by very simple operations.

Preparation of substance having antifungal, antiseptic, germicidal and preventing action on rancidification and growth promoting effect on animal

Abstract: PURPOSE:To obtain the titled substance with slight impurities easily in high yield, by extracting a by-product formed in the purification of rice bran oil, etc. with a hydrous organic solvent, and treating the by-product with a hydrocarbon solvent. CONSTITUTION:A by-product formed in the purification of rice bran oil or rice bran oil or dark oil or a fraction having a high boiling point >=200 deg.C obtained by the molecular distillation of a monohydric lower alcoholic ester of the dark oil is extracted with an alkaline solution of a monohydric alcohol, e.g. alkaline methanol, and then acidified weakly to separate a viscous material, which is then extracted with a hydrous organic solvent, e.g. methanol. After distilling off the organic solvent, a hydrocarbon solvent, e.g. n-hexane, is added to the resultant residue to remove tarry impurities completely, and then the remaining material is saponified with an alkali to remove and separate the impurities. The extract is then acidified to separate the aimed substance as an oil, which is then mixed with oryzanol and to give the aimed substance.

Preparation of food

Abstract: PURPOSE:To prevent the increase of serum cholesterol, by adding a mixed oil obtained by mixing a mixture of safflower oil and rice bran oil with nearly equal amount of tallow to a food, or by using the mixed oil for the cooking of a food. CONSTITUTION:A rice bran oil containing 20-40% safflower oil is mixed with 130-70%, preferably equal amount of tallow (beef tallow, lard, sheep suet, etc.), and the mixed oil is used as an additive for sausage, minched meat, hamburger, etc., or an oil for frying pork cutlet, fry, etc. When the mixed oil is liquid at normal temperature, it is emulsified with lecithin, sugar ester, soybean protein, etc.

Additive oil for feed used in fish breeding

Abstract: PURPOSE:To enhance the breeding effect of an eel, etc., by adding a mixture of a residual fish oil (obtained from entrails and bones of fishes discharged from canning plants, fish markets, etc.) having a specific iodine value with a rice bran oil to a feed therefor. CONSTITUTION:A residual fish oil (obtained from entrails and bones of fishes discharged from canning plants, fish markets, etc.) is mixed with a rice bran oil to adjust the iodine value of the mixed oil to 125-150. In one example, 5-10%, based on a feed for fish breeding, mixed oil is added thereto, and the breeding tests for 3 months showed the total body weight increase of about 1.2-1.3 times that of the feed in the absence of the mixed oil.

Production of composition having activity of lowering or inhibiting increase in cholesterol

Abstract: PURPOSE:Bran oil, diluted with an organic solvent, is cooled down to a specific temperature to separate the solid fraction and the maining fraction is subjected to columnchromatography fractionation to collect a specific fraction, thus obtaining the titled composition with low ingestion resistance and high safety. CONSTITUTION:Rice bran oil is diluted with an organic solvent such as methyl ethyl ketone or ethyl acetate and stood cooling down to -30--90 deg.C, preferably -50--70 deg.C. A cooling method is, e.g., to use dry ice-methanol medium. Then, the solid fraction is removed and the resultant fraction is subjected to column chromatography fractionation to collect the fraction that is not eluted with a solvent of lower than 7.5 solubility parameter such as hexane or diethyl ether, but eluted with a solvent of more than 7.5 such as acetone or ethanol to give a composition showing cholesterol-depressant or rise-inhibiting activity. The dose is more than 200mg a day calculated as the above composition.
