A vegetable oil physical refining process able to mitigate the occurrence of glycidyl esters (GE) including at least a deodorization step followed by a stripping step, wherein, the deodorization step includes contacting said vegetable oil with steam at a pressure above 5 mbara, during at least 10 minutes at a temperature of at least 230° C., and wherein the stripping step includes stripping the oil resulting from the deodorization step at a pressure below 5 mbara and at a temperature not exceeding 280° C. The process does not compromise the heat bleaching and the full removal of unwanted colours, taste and smell from the physically refined edible oil.

A method for extracting high-quality krill oil from krill includes the following steps: S1. performing extraction on krill with an organic solvent, and collecting an extracting solution; S2. adding alkaline water to the extracting solution to enable a free fatty acid to form a fatty acid salt to be separated from an oil phase, and performing oil-water phase separation and collecting the oil phase; and S3. purifying the oil phase to obtain the high-quality krill oil. In the present application, the preparation process for krill oil is optimized, organic solvent extraction and alkali refining are ingeniously combined, and process parameters are adjusted and optimized, thereby reducing the acid value of krill oil, and also ensuring the content of active ingredients such as phospholipid and astaxanthin in krill oil to the greatest extent, and improving the quality of krill oil.

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.

The present invention relates to a process reducing in a palm oil the content of unwanted propanol components selected from free chloropropanols, chloropropanol fatty acid esters and combinations of two or more thereof, and the process is comprising a bleaching step using an adsorbent comprising alumina oxide wherein the content of alumina oxide is not more than 9.5%, preferably the adsorbent is having a content of earth alkali oxides of from 12 to 27%.

The invention provides a method for the purifying of low-quality glyceridic material usually unfit for use as feed or food. The method includes a thermal treatment of the low-quality glyceridic material and chemical treatments. The purified oils and fat are suitable feed-stock or suitable components thereof for a hydrogenation processes yielding to high quality renewable diesel. The process thus permits the recycling of waste material that is usually discarded, into a valuable high-quality fuel.

The present invention relates to a method of for extracting oil from an oil-containing phospholipid composition, comprising the steps of: (a) Providing the oil-containing phospholipid composition, said composition comprising phospholipids and oil, the oil being in an amount of between and 80 wt % relative to the total weight of the oil composition; (b) Admixing water with the oil-containing phospholipid composition to obtain an aqueous composition, wherein the weight ratio of composition to water is between 6.0:1.0 and 1.3:1.0; (c) Separating the aqueous composition into an oil-rich fraction and an oil-depleted fraction, the oil-depleted fraction comprising water and phospholipids; and (d) removing the separated oil-rich fraction to obtain an aqueous, oil-depleted fraction comprising phospholipids; (e) optionally drying the aqueous, oil-depleted fraction to obtain a dried oil-depleted fraction comprising phospholipids.

The present disclosure relates to the design of structural features that enable the facile and reproducible fabrication of a microfluidic reactor that eliminates the problem of scaling factors in turn enabling the broad integration of microchannel reactors to industrial scale production. The process is highlighted via the effective and successful scale up of a purification process for the removal of a variety of different classes of impurities from crude vegetable oils mixtures into feedstocks that can be directly integrated into the hydrotreatment vegetable oil hydrogenation process for mass production of synthetic diesel derived from renewable sources.

A method of extracting oil from biological raw material includes creating a slurry of biological raw material, raising or lowering a pH of the slurry to separate lipid and protein components in the slurry, further separating the lipid and protein components into a first lipid rich phase and a protein rich phase, adjusting a pH of the first lipid rich phase to a point at which additional proteins in the first lipid rich phase coagulate, and recovering a second lipid rich phase from the additional coagulated proteins.

A method of recovering one or more insoluble oils from a liquid source using one or more membrane or membrane contactors, comprising the steps of: pumping the liquid source comprising the one or more oils to the membranes or membrane contactors, contacting the liquid source with a first surface of the membrane or membrane contactors, coalescing the one or more oils within the liquid source onto the first surface of the membrane contactors, pumping one or more recovery fluids through the membrane or membrane contactors in contact with the second surface of the membrane or membrane contactors, and removing a first stream of oil coalesced from the second surface of the membranes or membrane contactors.

Biological compositions containing animal fats and plant oils desirably are free of contaminants prior to processing into a biofuel. Disclosed herein is a method of removing such contaminants from these compositions to make that processing more efficient. The method employs a unique arrangement of mixers and centrifuges along with acidic solutions and recycle streams to remove these contaminants from the compositions.
