The present invention relates to a method of preparing a crocodile oil to reduce unpleasant odour comprising: preparing crocodile fats and mucosal tissues; adding water to the crocodile fats in the ratio of water to crocodile fats at 1:15 by weight, heating the crocodile fats until boiling; adding the mucosal tissues of crocodiles into the boiled crocodile fats until an oil is rendered from the crocodile fats; cooling down the crocodile fats to room temperature to obtain a crude crocodile oil; adding water, plant essence and emulsifier to the crude crocodile oil and mixing to obtain a crude crocodile oil mixture; filtering out oil dregs from the crude crocodile oil mixture; passing the remaining white liquid through a high pressure homogenizer to obtain a scented crocodile oil; and adding 15 to 20 ml of ginger oil to every 5000 ml of the scented crocodile oil and obtain the crocodile oil.

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 method for producing renewable diesel includes introducing a primary feedstock comprising biologically-derived triglycerides with catalyst poisons into a first reaction chamber and hydrolyzing the primary feedstock within the first reaction and liquid-liquid extraction chamber for at least an hour such that the reacted triglycerides are separated into an aqueous solution comprising glycerol and catalyst poisons, and an intermediate feedstock comprising free fatty acids and catalyst poisons. The method also includes distilling the intermediate feedstock to separate the intermediate feedstock into a purified intermediate stream and a lower volume bottom stream containing unreacted triglyceride, diglyceride, monoglyceride, FFA and catalyst poisons. The method also includes combining the purified intermediate feedstock with a hydrogen stream and converting, in a second reaction chamber comprising a metallic catalyst bed, the purified intermediate feedstock into a product comprising long-chain alkanes. The method also includes hydrotreating the purified intermediate feedstock into a renewable diesel product.

The present invention relates to methods of synthesizing long-chain polyunsaturated fatty acids, especially eicosapentaenoic acid, docosapentaenoic acid and docosahexaenoic acid, in recombinant cells such as yeast or plant cells. Also provided are recombinant cells or plants which produce long-chain polyunsaturated fatty acids. Furthermore, the present invention relates to a group of new enzymes which possess desaturase or elongase activity that can be used in methods of synthesizing long-chain polyunsaturated fatty acids.

Methods of refining palm oil in order to produce a refined, bleached and deodorized palm oil with reduced level of 3-monochloropropane-1, 2-diol (3-MCPD) ester are disclosed. The methods may include premixing a palm oil with an acid to chelate metals and form a reaction mixture, and subjecting the reaction mixture to hydrodynamic cavitation mixing for less than 1 second.

The present invention provides an improved method for purification of a primary triacylglyceride oil comprising the steps of washing the primary triacylglyceride oil, trapping assisted removal of chlorinated precursors of MCPDEs by admixing the primary triacylglyceride oil with an auxiliary trapping agent; crystallising the auxiliary trapping agent or the primary triacylglyceride oil; and separating solid and liquid phases of the product.

The present invention discloses solvent free process for extracting cholesterol free of impurities from milk fat. The so isolated cholesterol is useful for the further preparation of vitamin D3. The present invention further provides pharmaceutical grade cholesterol from milk fat of high purity.

Methods for reducing the color of phospholipid compositions comprising lecithin are disclosed. The phospholipid composition is exposed to ultraviolet light to reduce the color of the composition. The phospholipid composition may be diluted and/or heated prior to exposure to ultraviolet light to improve the flow properties of the composition. The phospholipid composition may be cooled and/or concentrated after color reduction.

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.
