The present invention addresses the problem of providing, by a simple method, a method for conferring photodegradation resistance on cocoa butter, which has low photodegradation resistance. By performing degumming treatment using phospholipase, photodegradation resistance can be conferred to cocoa butter. When white chocolate was prepared using the thus-obtained cocoa butter, photodegradation was remarkably suppressed. Although any kind of phospholipase may be used, the use of phospholipase A2 is preferred as the effect therewith is particularly remarkable.

The present invention provides a method of producing/purifying highly unsaturated fatty acids and/or derivatives thereof while suppressing deterioration of a silver salt aqueous solution, in production/purification of highly unsaturated fatty acids and/or derivatives thereof using the aqueous solution of silver salt. The present invention also contacts or mixes a mixture having a peroxide value (POV) of 10 or smaller with an aqueous solution of silver salt, in a method of purifying highly unsaturated fatty acids and/or derivatives thereof from a mixture comprising highly unsaturated fatty acids and/or derivatives thereof.

Described herein is a polymerized biorenewable, petroleum based, previously modified, or functionalized oil, comprising a polymeric distribution ranging from about 2 to about 80 wt % oligomer content, a hydroxyl value ranging from about 0 to about 400, and an iodine value ranging from about 0 to about 200. Methods of manufacturing the polymerized oil as well as its incorporation into asphalt paving, roofing, and coating applications are also described.

This application relates to canola oils comprising triacylglycerols (TAGs), wherein 11-16% of the total TAGs in the oil comprise one saturated fatty acid and two unsaturated fatty acids and wherein 82-88% of total TAGs comprise three unsaturated fatty acids, and wherein 81-91% of the total TAGs comprise at least one oleic acid and wherein 7-12% of the total TAGs comprise at least one linolenic acid. In some embodiments, the oils have a low saturated fatty acid content of 3.5-5.5%, such as 3.5-4.5%, or 3.5-4.0%.

A methodology for cleaning and upgrading any kind of tires (cars, motorcycles, trucks, etc.), any kind of waste lubricants (internal combustion engines, industrial parts), any kind of oils as well as plant and animal fats by means of removal of the inorganic elements (potassium, sodium, chlorine, sulfur, phosphorus and heavy metals such as Pb, Cu, Cd, Zn, Hg, Mn, etc.) and the simultaneous addition of new such as calcium, magnesium and ammonium, in order to produce a clean and upgraded rubber material, lubricant as well as fat/oil, which can be used as raw material in thermochemical conversion processes such as flash (t<1 sec)/fast pyrolysis.

The present invention relates to extraction of phytosterols from alkaline tall oil soap which is obtained from the Kraft process black liquor by skimming. In the method according to the present invention, phytosterols are extracted using dibromomethane, bromoform, tetrabromomethane or a combination thereof.

Methods and compositions for the production of dielectric fluids from lipids produced by microorganisms are provided, including oil-bearing microorganisms and methods of low cost cultivation of such microorganisms. Microalgal cells containing exogenous genes encoding, for example, a sucrose transporter, a sucrose invertase, a fructokinase, a polysaccharide-degrading enzyme, a lipid pathway modification enzyme, a fatty acyl-ACP thioesterase, a desaturase, a fatty acyl-CoA/aldehyde reductase, and/or an acyl carrier protein are useful in manufacturing dielectric fluids.

Methods and systems for filtering a plant-derived extract to remove contaminants, including a filter column containing a filter medium and a vacuum pump. The plant-derived extract is mixed with a solvent, and drawn through the filter column across the filter medium. In various embodiments, the solvent and filter medium may be selected to target specific contaminants or classes of contaminants, such as herbicides, insecticides, fungicides and/or other synthetic agrichemicals.
