PROBLEM To provide a composition comprising highly enriched PUFA or its alkyl esters while containing fatty acid esters of 3-MCPD at adequately low concentrations and to provide an efficient method for producing the composition.

MEANS FOR SOLVING A composition that contains fatty acids or fatty acid alkyl esters as its major component, the composition containing highly unsaturated fatty acid or alkyl ester thereof, wherein the proportion of the highly unsaturated fatty acid in the constituent fatty acids of the composition is 50 area % or more and wherein the concentration of 3-MCPD as found upon analyzing the composition by American Oil Chemists' Society official method Cd 29b-13 assay A is less than 1.80 ppm.

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.

A method for preparing field muskmelon oil includes the following steps: S1, removing foreign matter, including: removing the foreign matter in field muskmelon seeds; S2, low-temperature pressing, including: performing the low-temperature pressing on the field muskmelon seeds after removing the foreign matter in step S1 to obtain an oil residue mixture; S3, filtering and removing impurities: filtering the oil residue mixture obtained by the low-temperature pressing in step S2 to remove the impurities to obtain a primary oil; and S4, centrifugal separation, including: centrifugally separating the primary oil obtained by filtering and removing impurities in step S3 to obtain the field muskmelon oil. The new method avoids using high-temperatures resulting in optimal yield of nutritional content and no harmful byproducts.

A product matter of generally expanding the life of edible cooking oil used to deep fry wherein a combination of diatomaceous earth and anhydrous magnesium silicate are used as a fry and filtering aid.

A method for producing a carotenoid enriched fatty acid composition includes: reacting an oil including free fatty acids and carotenoids with a basic solution; withdrawing, separately from the oil, an extraction solution including at least a portion of the free fatty acids, at least a portion of the carotenoids, and the basic solution; acidifying the extraction solution to produce an aqueous phase and a fatty acid phase, the fatty acid phase including the free fatty acids and the carotenoids of the extraction solution; and separating the fatty acid phase from the aqueous phase.

A method for refining vegetable oil is used to reduce formation of soaps. An acid-treated vegetable oil mixture is passed through a low shear mixing device prior to being fed to a static hydrodynamic reactor. The static hydrodynamic reactor induces a neutralization reaction that forms soaps in a pressurized vegetable oil mixture. The reacted mixture is discharged from the reactor to a downstream system for separating the formed soaps from the reacted mixture to form a refined vegetable oil having reduced soaps content.

The present invention relates to a method of making a dough, said method comprises admixing a dough component, a phospholipase A2 enzyme which acts on N-acyl phosphatidyl ethanolamine at the sn2 position, and an enzyme that acts on a polar lipid at the sn1 position. A food enzyme composition comprising: a phospholipase A2 enzyme which is capable of acting on N-acylphosphatidyl ethanolamine at the sn2 position; and an enzyme that acts on a polar lipid at the sn1 position is also taught.

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.

Provided are methods and systems for treating a soapstock. Provided are systems and methods for treating a soapstock to generate free fatty acids and/or fatty acid derivatives, and for realizing the full fatty acid yield of a soapstock by first converting substantially all of the saponifiable material in a soapstock to fatty acids and acidulating the soaps to generate free fatty acids and/or fatty acid derivatives, wherein the soapstock comprises soaps and saponifiable lipids, and the generating of free fatty acids is achieved. Provided are systems and methods for realizing the full fatty acid yield of a soapstock by first converting substantially all of the saponifiable material in a soapstock to salts of fatty acids and acidulating the soaps to generate free fatty acids and/or fatty acid derivatives, wherein the soapstock comprises soaps and saponifiable lipids, and the generating of free fatty acids is achieved.
