A preparation method of eicosapentaenoic acid (EPA) ethyl ester is provided and relates to the field of EPA ethyl ester processing technologies. The preparation method includes: performing degumming and deacidification on a sardine crude oil to obtain a semi-refined sardine oil, performing esterification on the semi-refined sardine oil to obtain an esterified sardine oil and then performing winterization on the esterified sardine oil to thereby obtain an semi-refined esterified sardine oil, performing bleaching and deodorization on the semi-refined esterified sardine oil, and performing multi-stage distillation treatment. Finally, the sardine oil is purified by liquid chromatography to obtain the high purity EPA ethyl ester. The preparation method can improve a utilization rate of the sardine oil and obtain the high-purity EPA ethyl ester.

The invention relates to a process for enzymatic degumming of unrefined triglyceride oil, said process comprising the following successive steps: (a) providing an unrefined triglyceride oil having a phosphorus content of at least 100 mg per kg of unrefined triglyceride oil; (b) combining the unrefined triglyceride oil with water, an acid and a phospholipase to produce an oil-in-water emulsion having a pH in the range of 2.5 to 4.5; said phospholipase being selected phospholipase A1, phospholipase A2 and combinations thereof; (c) keeping the emulsion at a temperature of 20-90° C. for at least 10 minutes; (d) introducing a base into the emulsion; and (e) separating degummed triglyceride oil from the emulsion. This enzymatic degumming process is extremely effective in removing phospholipids, including non-hydratable phospholipids (NHP), from unrefined vegetable oils and produces degummed vegetable oil in high yield.

The present invention addresses the problem of providing an oil/fat in which the glycidol content and glycidol fatty acid ester content are reduced. A method for manufacturing an edible fat/oil, wherein a step for decolorizing and deodorizing an oil/fat that contains a palm-based oil/fat, in which physically refined palm oil (RBDPO) is used as a raw material, includes a step for performing an acid-induced contacting process during a decolorization work step.

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.
