摘要： Present invention relates to a process for reducing the MOSH and/or MOAH content from vegetable oil selected from the group consisting of palm-based oil, cocoa butter-based oil and any mixtures thereof, and comprising steps of: a) subjecting the vegetable oil to a short-path evaporation, wherein the short-path evaporation is performed at a pressure of below 1 mbar, at an evaporation temperature in a range of from 235 and 290° C., and with a feed rate per unit area of evaporator surface of the shorth-path evaporation equipment in a range of from 35 to 102 kg/h·m2, and thus obtaining a retentate vegetable oil and a distillate, b) Contacting the retentate vegetable oil with an adsorbent, and c) Subjecting the bleached retentate vegetable oil to a further refining step.

摘要： 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.

摘要： A method of fractionating a mannosylerythritol lipids (MELs) containing composition by loading the composition onto an adsorbing support, separating a fraction which is enriched in MELs from the support using supercritical carbon dioxide, and optionally separating one or more further fractions enriched in MELs from the support using supercritical carbon dioxide and an optional co-solvent. The MELs can be obtained at high concentration by using only “green” solvents.

摘要： The present invention relates to a fixed bed decolorization process for an polyunsaturated fatty acid, comprising a polyunsaturated fatty acid or a polyunsaturated fatty acid solution is either passed directly through a filler of the fixed bed or recycled in a filler of the fixed bed, a colorless or light-colored polyunsaturated fatty acid product is ultimately produced, at the same time, other than the color, other qualities of the polyunsaturated fatty acid remain unaffected. The decolorization process allows continuous operation or intermittent operation. The filler of the fixed bed comprises one or a mixture of activated carbon, diatomite, carclazyte, silicone and an ion-exchange resin. An upper or a middle or a bottom or a combination thereof is employed to feed a polyunsaturated fatty acid feedstock or a polyunsaturated fatty acid solution. The filler in the fixed bed can be used repeatedly. The filler can be reused after being washed when decolorization effects thereof become deteriorated or ineffective.
