The present disclosure is related to a multistep process for producing renewable gasoline components from a glyceride containing feedstock. The glycerides are split to provide a stream containing fatty acids, or esters of fatty acids, and another stream containing glycerol and water. Glycerol, preferably as crude glycerol recovered from splitting, is next converted to propanols at vapor phase, providing a renewable propanol gasoline component. Another renewable gasoline component is obtained from hydroprocessing of the fatty acids or esters thereof, as a renewable paraffinic naphtha component. Blending the renewable components can provide a novel 100% renewable gasoline.

[Object] To provide an oil and fat composition that can be used as a low trans fatty acid content, non-lauric, non-tempering type hard butter and an oil-based food product comprising the oil and fat composition that exhibits good heat resistance and melting feeling in the mouth. [Means for Solving the Problems] The oil and fat composition of the present invention is characterized by satisfying the following conditions of (a) to (g): (a) an X3 content is 3 to 20% by weight; (b) a weight ratio of P3/X3 is not less than 0.35; (c) an X2O content is 45 to 80% by weight; (d) a weight ratio of XOX/X2O is 0.20 to 0.65; (e) a weight ratio of PStO/X2O is 0.10 to 0.45; (f) a weight ratio of St2O/X2O is 0.05 to 0.35; and (g) a weight ratio of St/P is not more than 0.80; wherein X represents saturated fatty acid having 14 carbon atoms or more; O represents oleic acid; P represents palmitic acid; and St represents stearic acid.

Provided herein are microalgae of a Thraustochytrid and a method for preparing bio-oil using the same, and more particularly, Aurantiochytrium sp. LA3 (KCTC12685BP) having bio-oil producibility, and a method of preparing bio-oil, particularly bio-oil having a content of omega-3 unsaturated fatty acids of 30% by weight or more based on total fatty acids, characterized by culturing the microalgae. The microalgae Aurantiochytrium sp. LA3 (KCTC12685BP) described herein has a rapid sugar consumption rate when being cultured using glucose as a carbon source, has a high oil content, allows cells to be cultured at a high concentration, and allows oil to be obtained in high productivity and a high yield, and thus, may produce bio-oil more economically and environmentally friendly.

Products produced from distillers corn oil include once refined corn oil product, food grade corn oil product, and free fatty acid product which may be used in a variety of applications. The products have varying specifications for free fatty acid content and moisture content. The applications include food, feed, additives, and manufacture of industrial products.

Disclosed are methods of recovering urea from a urea/oil complex by drying the complex, combining the complex with water to form a urea solution, and removing water from the urea solution. Methods for recycling the urea in urea complexation processes are also disclosed. Also disclosed are methods of recovering polyunsaturated fatty acids or derivatives thereof from the urea/oil complexes.

Aspects of the present invention provide methods of drying lecithin in a batch reaction, comprising the steps of obtaining lecithin-containing material (derived from a crude refining stream) comprising 15-50% water, 10-30% acetone insoluble matter, and 10-20% free fatty acid; adding a fatty acid source (also derived from a crude refining stream) to the lecithin-containing material composition to obtain a lecithin/fatty acid reaction mixture; and blowing dry gas through the gum/fatty acid reaction miture to obtain a resultant dried lecithin fatty acid blend having a water content of less than 2%. The resultant dried lecithin fatty acid blend may be used in asphalt or oil field applications.

A method for purification of a triacylglyceride oil comprising the steps of concentrating the insoluble components in the melted triacylglyceride oil, by applying a centrifugational force on the liquid triacylglyceride oil whilst maintaining the triacylglyceride oil above its melting temperature; and/or allowing the insoluble components to settle by gravitational force whilst maintaining the triacylglyceride oil above its melting temperature; and separating the triacylglyceride oil from the insoluble components. A triacylglyceride oil obtained by the method of the invention for use in food production is also provided.

The present invention provides a chromatographic separation process for recovering a polyunsaturated fatty acid (PUFA) product from a feed mixture, which process comprises passing the feed mixture through one or more chromatographic columns containing, as eluent, an aqueous organic solvent, wherein the temperature of at least one of the chromatographic columns through which the feed mixture is passed is greater than room temperature.

One or more techniques are disclosed for a process of preparing stearic acid from animal and/or plant sources may comprise: 1) deodorizing and distilling a fat; 2) concentrating fatty acids of the fat; and 3) hydrogenating the fatty acid to provide stearic acid. The process may include the use of co-products from plant and/or animal sources. The process may also include distilling the stearic acid to provide palmitic acid and/or fully hydrogenated fatty acid. Tallow fatty acid, vegetable fatty acid, stearic acid, and palmitic acid prepared from the process described are also disclosed.

A method is provided for preventing or reducing the formation of monochloropropanediols (MCPDs) or monochloropropanediol esters (MCPDEs) in triacylglyceride oil, comprising the steps: (a) concentrating insoluble components in liquid triacylglyceride oil by (i) applying a 5 centrifugational force on the triacylglyceride oil whilst maintaining the triacylglyceride oil above its melting temperature; and/or (ii) allowing the insoluble components to settle by gravitational force whilst maintaining the triacylglyceride oil above its melting temperature; (b) separating the triacylglyceride oil from the insoluble components; (c) optionally applying additional refining steps and (d) applying heat treatment to the triacylglyceride oil. A purified 10 triacylglyceride oil obtainable by the method of the invention is also provided.
