    • An easy and inexpensive process by which a concentrate of a given unsaturated fatty acid can be obtained from a mixture which has conventionally been difficult to concentrate. The process, which is for producing a concentrate of a desired isomer (a) from a conjugated fatty acid mixture (A), is characterized by comprising: a step in which the conjugated fatty acid mixture (A) is mixed with at least one unsaturated fatty acid (B) to obtain a mixture solution containing the isomer (a) dissolved therein; a crystallization step in which either crystals rich in the isomer (a) or crystals poor in the isomer (a) are precipitated from the mixture solution; and a solid-liquid separation step for obtaining the crystals rich in the isomer (a) or for obtaining a solution rich in the isomer (a) by removing the crystals poor in the isomer (a).
    • 一种容易且廉价的方法,通过该方法可以从常规难以浓缩的混合物中获得给定的不饱和脂肪酸的浓缩物。 用于由共轭脂肪酸混合物(A)生产所需异构体(a)的浓缩物的方法的特征在于包括:将共轭脂肪酸混合物(A)与至少一种不饱和脂肪酸混合物 脂肪酸(B),得到含有溶解于其中的异构体(a)的混合溶液; 从混合溶液中析出析出富含异构体(a)或异构体(a)的晶体不足的晶体的结晶步骤; 以及固体 - 液体分离步骤,用于通过除去异构体(a)中的不稳定的晶体来获得富含异构体(a)的晶体或用于获得富含异构体(a)的溶液。
