MEMBRANE method of reducing at least one of impurities and obtain a concentrate containing at least one natural component from a mixture of oils non-marine fatty acids, and the resulting composition

摘要

1. A method for reducing at least one impurity and / or obtain a concentrate containing at least one impurity, which in this case is a natural component of the mixture does not marine oils fatty acid, comprising: (a) mixing the oil mixture does not marine fatty acids with an organic solvent to form a solution; (b) passing the solution through at least one selective membrane, to obtain a concentrate containing oil, and the filtrate, containing at least one impurity; and (c) removing the organic solvent from the concentrate to obtain a purified not marine oils, wherein the at least one impurity in the purified not marine oil is reduced in comparison with the mixture of oils is not marine fatty acids, wherein the mixture of oils is not marine fatty acid contains no marine oil selected from triglyceride oils, phospholipid oils and any combination thereof; and wherein the membrane used is characterized by a retention coefficient Rtselevyh compounds triglyceride oils, phospholipid oils and / or mixtures thereof which is greater than the membrane retention coefficient R2 impurities. A method according to Claim. 1, wherein passing the solution through at least one selective membrane includes diafiltration or cross-flow filtration in / tangential flow, preferably at a linear velocity of about 0.1 m / s to 5 m / s, particularly preferably from about 0.5 m / s to about 3 m / s, or a combination of slide and cross-flow filtration and / or wherein the method is carried out at a temperature from about -10 ° C to about 60 ° C, preferably from about 25 ° C to about 50 ° C, and / or wherein the solution is passed through at least one selective m
