The present invention provides a process for the enzymatic degumming of unrefined triglyceride oils, said process comprising: 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, lactic acid and enzyme to produce an oil-and-water emulsion, said enzyme being selected from phospholipase, lipid acyltransferase and combinations thereof; c) keeping the emulsion at a temperature of 20-90° C. for at least 10 minutes; and d) separating degummed triglyceride oil from the emulsion. This enzymatic degumming process is extremely effective in removing phospholipids, including non-hydratable phospholipids (NHP), from crude and other unrefined vegetable oils.

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 provides a method of efficiently separating solid fat from polyunsaturated fatty acid grease. The method comprises adding a certain amount of inert material to the polyunsaturated fatty acid grease, and cooling crystallization, and then filtering through a filter to obtain clarified polyunsaturated fatty acid grease. Afterwards introducing hot gas through the filter to make solid fat adsorbed on a filter cake in the filter dissolved and then recycling it through a filter plate. Inert solid substances can be applied next time. The method of the present invention can be efficiently separated saturated and low-saturated fatty acids from polyunsaturated fatty acid grease. In the process, the winterization crystallization time is short, the crystallization is complete, the crystal separation is easy. It will not cause some solid fat melted and thus re-enter the filtrate due to long separation and blowing dry in conventional process. The yield of final product is high up to 89.8%-97.8%. After winterization, a lipid clarity of the polyunsaturated fatty acid grease is good, and no crystal precipitation would occur at 0° C. for 5 hrs.

[Problem] To provide: a method for suppressing the coloration of oils and fats during frying; and a coloring inhibitor. [Solution] A method for suppressing the coloration of an oil/fat composition for frying, the method comprising a step for adding a prepared oil to an edible oil or fat, wherein the prepared oil is obtained through (1) a degumming step, (2) a neutralization step which may or may not be performed, (3) a bleaching step which may or may not be performed, and (4) a deodorizing step, in this order, in the process of refining a crude oil obtained from an oil feedstock, and the absorbance difference determined by subtracting the absorbance at a wavelength of 750 nm from the absorbance at a wavelength of 660 nm of the prepared oil obtained from step (3) is at least 0.030 when isooctane is used as the control. A coloring inhibitor characterized by containing said prepared oil.

The present invention relates to a polyunsaturated fatty acid composition comprising Omega-3 fatty acids, 17-HDHA and 18-HEPE. The composition can furthermore comprise DPA and/or an acceptable carrier and can be present in a capsule or other suitable dosage unit. The invention also relates to the process of obtaining the composition and methods for using same.

The invention relates to a process for purification of oil by heat treatment in order to degrade phospholipids present in the non-purified oil.

The disclosure provides a method of obtaining an isolated phospholipid enriched krill composition. The method includes a) contacting a crude krill composition with an alcohol in an amount sufficient to provide a phospholipid enriched layer and a non-phospholipid enriched layer; b) forming a phospholipid enriched layer and a non-phospholipid enriched layer, wherein the phospholipid enriched layer is above the non-phospholipid enriched layer; c) isolating the phospholipid enriched layer and the non-phospholipid enriched layer; and d) removing the alcohol from the phospholipid enriched layer to provide an isolated phospholipid enriched krill composition.

There is a method for extracting bio-oil from algal biomass, in particular oily microalgae, using solvents of a Deep Eutectic Solvents (DES) capable of producing a bio-oil with a low content of phospholipids and inorganic salts, mainly sodium chloride.
