The present invention relates to process for enlarging oleosomes and the process comprises subjecting isolated oleosomes to a high-shear mixing or a high-shear centrifugal force, and obtaining an oleosome composition. The invention further relates to oleosome compositions. It also relates to food and feed products, pharmaceutical products, personal care products, nutritional compositions and industrial products comprising said oleosome composition. The invention relates to the process of preparing nutritional compositions comprising oleosome compositions. The current invention further relates to the use of rotor-stator high-shear mixer and/or a disk-stack centrifuge for enlarging the average globule diameter of oleosomes in an oleosome composition

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.

A method is provided for preventing or reducing the formation of monochloropropanediols (MCPDs) or monochloro-propanediol esters (MCPDEs) in triacylglyceride oil, comprising the steps: (a) concentrating insoluble components in liquid starting triacylglyceride oil by (i) applying a centrifugational force on the triacylglyceride oil whilst maintaining the triacylglyceride oil above its melting temperature; and/or (ii) allowing the insoluble components to settle by gravitational force whilst maintaining the triacylglyceride oil above its melting temperature; (b) separating the triacylglyceride oil from the insoluble components; (c) optionally applying additional refining steps and (d) applying heat treatment to the triacylglyceride oil. A purified triacylglyceride oil obtainable by the method of the invention is also provided.

MIU and metals are removed from Tallow or Seed based oils (feedstock) utilizing water treated by reverse osmosis and specific operating conditions using a very high RCF centrifuge. A relatively small quantity of the RO water (3% to 20% by weight) is added to the feedstock to attract the MIU and metals. The mixture is then centrifuged at an RCF in excess of approximately 6500. Temperature, flow rate to control Residence time and backpressure in the centrifuge are selected. The process separates the RO water with the MIU and metals from the feedstock.

A coalescence method and related system are disclosed herein. A multiphase dispersion feed comprising first and second liquids (i.e. where droplets of the first liquid (dispersed phase) are dispersed in the second liquid (continuous phase)) is passed through a static mechanical droplet-coalescer comprising a channel characterized by a plurality of in-series segments, each segment characterized by a segment-specific-characteristic obstacle size and having geometric features disclosed herein. In embodiments of the invention, the static mechanical droplet-coalescer promotes coalescence between droplets of first liquid to form larger droplets of first liquid. Subsequently, after the dispersion exits the coalescer, the larger droplets are easier to remove from the second liquid (continuous phase) than the smaller droplets that coalesced into the larger droplets.
