A method for producing biodiesel using a sulfonated, carbonaceous catalyst produced from rice husk, Moringa seeds, or algae biomass, a method for producing the catalyst, and the catalyst itself.

Provided are a heating-odor-suppressing agent for a cooking oil or fat composition, a method for suppressing a heating odor in a cooking oil or fat composition, and a method for producing the cooking oil or fat composition that make it possible to suppress the heating odor of an oil or fat produced during cooking of deep-fried foods or the like.

The heating-odor-suppressing agent for a cooking oil or fat composition contains corn-derived roasted oil as an active component. Moreover, the method for suppressing a heating odor in a cooking oil or fat composition involves including corn-derived roasted oil in the cooking oil or fat composition. Furthermore, the method for producing a cooking oil or fat composition comprises mixing corn-derived roasted oil and an edible oil or fat other than the roasted oil to thereby obtain an oil or fat composition that contains 0.01% by mass or more to 10% by mass or less of the roasted oil.

The method of producing a lipid composition comprises an extraction treatment step to extract a lipid comprised in a hydrated raw material by using an extraction solvent comprising a polar solvent and a nonpolar solvent, and a separation treatment step to separate an extract solution obtained in the extraction treatment step into a polar solvent phase comprising a first lipid fraction and a nonpolar solvent phase comprising a second lipid fraction.

The present invention relates to a process for preparing purified vegetable liquid oil, and the process is comprising contacting a vegetable liquid oil, which has not been subjected to a deodorization step, with an adsorbent comprising alumina oxide and wherein the adsorbent has a content of alumina oxide of not more than 9.5% and the obtained deodorized vegetable liquid oils.

The invention relates to a method for the purification of crude rice bran wax using an alcohol as a purifying solvent under high pressure conditions. It particularly relates to the use of ethyl alcohol as said solvent for efficient and economic purification of crude rice bran wax into economically valuable high purity wax products.

This invention discloses new krill oil compositions characterized by having high amounts of phospholipids, astaxanthin esters and/or omega-3 contents. The krill oils are obtained from krill meal using supercritical fluid extraction in a two stage process. Stage 1 removes the neutral lipid by extracting with neat supercritical CO.sub.2 or CO.sub.2 plus approximately 5% of a co-solvent. Stage 2 extracts the actual krill oils by using supercritical CO.sub.2 in combination with approximately 20% ethanol. The krill oil materials obtained are compared with commercially available krill oil and found to be more bioeffective in a number of areas such as anti-inflammation, anti-oxidant effects, improving insulin resistances and improving blood lipid profile.

The present disclosure is related to refining one or more grain oil composition streams (e.g., distillers corn oil or syrup) in a biorefinery to provide one or more refined grain oil products, where each grain oil product has targeted amounts of a free fatty acid component and the fatty acid alkyl ester component.

The invention relates to a process for enzymatic degumming of unrefined triglyceride oil, said process comprising the following successive steps: (a) providing an unrefined triglyceride oil having a phosphorus content of at least 100 mg per kg of unrefined triglyceride oil; (b) combining the unrefined triglyceride oil with water, an acid and a phospholipase to produce an oil-in-water emulsion having a pH in the range of 2.5 to 4.5; said phospholipase being selected phospholipase A1, phospholipase A2 and combinations thereof; (c) keeping the emulsion at a temperature of 20-90 C. for at least 10 minutes; (d) introducing a base into the emulsion; and (e) separating degummed triglyceride oil from the emulsion. This enzymatic degumming process is extremely effective in removing phospholipids, including non-hydratable phospholipids (NHP), from unrefined vegetable oils and produces degummed vegetable oil in high yield.

The present invention relates to methods of synthesizing long-chain polyunsaturated fatty acids, especially eicosapentaenoic acid, docosapentaenoic acid and docosahexaenoic acid, in recombinant cells such as yeast or plant cells. Also provided are recombinant cells or plants which produce long-chain polyunsaturated fatty acids. Furthermore, the present invention relates to a group of new enzymes which possess desaturase or elongase activity that can be used in methods of synthesizing long-chain polyunsaturated fatty acids.

A method of remediating pesticides from an agricultural oil includes mixing a reaction solvent, a reducing agent, and an agricultural oil into a reaction mixture in a reaction vessel, controlling the temperature of the reaction mixture, producing a pre-neutralization mixture including a separation solvent, transferring the pre-neutralization mixture into a neutralization reactor that contains a neutralization agent, mixing the pre-neutralization mixture with the neutralization agent and allowing separation into an aqueous layer and a separation solvent layer, draining the aqueous layer, and distilling the separation solvent in the separation solvent layer from the remediated agricultural oils. A system has a reactor vessel, the reactor vessel having one or more inlets to allow a reducing agent, the agricultural oil, the separation solvent, and other additives as needed to produce a reaction mixture, a temperature control unit to control a temperature of the reaction mixture at a predetermined temperature for a predetermined time, a neutralization vessel fluidically connected to the reactor vessel to receive the reaction mixture from the reactor vessel, the neutralization vessel having an inlet to allow a neutralization agent to be introduced into the neutralization vessel to produce a neutralized reaction mixture, and a valve arranged at a bottom of the neutralization vessel to allow an aqueous phase of the reaction mixture to be drained from the neutralization vessel.
