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 invention relates to a non-dairy creamer and the triglyceride composition including a first ingredient, a second ingredient and a third ingredient. The first ingredient and the second ingredient together are from about 65wt % to about 80wt % by the weight of the triglyceride composition, and the third ingredient is from about 20wt % to about 35wt % by weight of the triglyceride composition. The first ingredient, the second ingredient and the third ingredient each have a MCPD content of less than 2500 ppb and a GE content of less than 1000 ppb. The first ingredient and the second ingredient are different, and the first ingredient and second ingredient are each selected from the group consisting of palm oil, palm kernel oil, palm kernel olein, palm kernel stearin, palm stearin, palm super stearin, palm olein, palm super olein, palm mid-fraction and a combination thereof. The third ingredient includes a lauric triglyceride.

The present disclosure is related to an apparatus and method for purification of biological feedstock, such as reducing or removing nitrogen containing compounds therein. The method can include subjecting the feedstock to a first separation step for obtaining a first fraction containing free fatty acids and nitrogen containing compounds, and collecting the residue containing acylglycerols. The first fraction is reacted with glycerol to obtain acylglycerols from the free fatty acid therein. This fraction is subjected to a second separation step for obtaining a second fraction containing nitrogen containing compounds, which is discharged as waste-product. The remains from the second separation contain formed acylglycerols and are collected.

A cooking oil degradation suppression filter that can effectively and easily suppress degradation of cooking oil without using a filter aid or the like and can prevent a decrease in the taste of food caused by separation of a degradation suppression agent. The cooking oil degradation suppression filter includes fiber (10) and at least one degradation suppression agent (13) selected from a carbonate, a silicate, a tartrate, an oxide, a hydroxide, an alginate, and a phosphate.

It is provided a process for producing a purified essential oil excellent in safety and quality with high productivity from an essential oil comprising a harmful contaminant such as an agricultural chemical by simply and smoothly removing the contaminant with high removal rate without causing poor balance of flavor which the essential oil originally has, decrease of flavor strength and the like. It relates to a process for producing a purified essential oil by treating an essential oil comprising a contaminant with an active carbon to remove the contaminant and the removal rate of the contaminant is further improved by using an active carbon activated with a chemical, particularly an active carbon activated with zinc chloride, in the treatment, or by conducting the treatment at a low temperature of room temperature or lower, particularly at 25 C. to 5 C.

A refined oil composition having a reduced 3-MCPD ester and/or glycidyl ester content and methods of preparation thereof.

A method for the combined synthesis of a mono-unsaturated nitrile-ester(acid) and of a bi-functional carbonyl compound, wherein it includes a step including the cross metathesis mc1 of an unsaturated fatty acid/ester compound with an unsaturated nitrile compound, in which mc1 is performed with partial conversion such as to obtain and recover, separately, at least the following products: a mono-unsaturated nitrile-ester/acid and a symmetrical compound, diester or diacid respectively including a double bond located in the middle of the molecular chain of compound, and subsequently a step including the oxidation cleavage cp2 of the double bond of compound, such as to form a single type of carbonyl compound having formula R2-(CH2)n-COR, in which R is H or OH, depending on the operating conditions selected for the oxidation cleavage cp2. Also, the production of monomers for the polymer industry.

The present invention relates to processes for extracting lipid from vegetative plant parts such as leaves, stems, roots and tubers, and for producing industrial products such as hydrocarbon products from the lipids. Preferred industrial products include alkyl esters which may be blended with petroleum based fuels.
