There is provided a vegetable-based lipid composition comprising very high levels of DHA, together with at least one other long-chain polyunsaturated fatty acid (typically as fatty acid esters). The composition typically contains low levels of EPA and palmitic acid. The composition is obtainable from a single source by conventional processing methods, and has improved stability properties.

The present invention relates to a process for preparing a deodorized oil with in-situ prepared mono-acylglycerides and the oil obtained as such. It relates to a process for preparing a deodorized oil containing in-situ prepared mono-acylglycerides by interesterifying in presence of an enzyme a glyceride containing fraction wherein the ratio of free and esterified hydroxyl groups (OH) to free and esterified fatty acids (FA) is greater than 1.07 and obtaining an oily composition containing less than 1% w/w, preferably less than 0.5% free fatty acids. Furthermore it relates to a deodorized oil containing 30 to 70% triglycerides, 20 to 50% di-acyl glycerides, 1.5 to 25% mono-acyl glycerides.

A highly unsaturated fatty acid or a highly unsaturated fatty acid ethyl ester that has been produced using as a feedstock oil a fat or oil that contains highly unsaturated fatty acids as constituent fatty acids and which has been reduced in the contents of environmental pollutants, wherein among the dioxins contained, polychlorinated dibenzoparadioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are contained in amounts of less than 0.05 pg-TEQ/g and coplanar PCBs (Co-PCBs) in amounts of less than 0.03 pg-TEQ/g. Also disclosed is a method for producing the highly unsaturated fatty acid or highly unsaturated fatty acid ethyl ester by the steps of removing free fatty acids and environmental pollutants by thin-film distillation from a feedstock oil, ethyl esterifying the resulting fat or oil, and refining the same by rectification and column chromatography.

The invention provides a method and apparatus for continuous extraction of plant oils from plant tissue using an advantageous azeotrope of ethanol and water and employing the differing solubility of plant oils in ethanol and water to drive formation of a non-toxic oil tincture.
