The separation of polyunsaturated triglycerides from monounsaturated triglycerides and polyunsaturated fatty acids from monounsaturated fatty acids is performed by an adsorptive chromatographic process in liquid phase using silver- or copper-exchanged aluminosilicates as the adsorbent. The exchange ions limit deactivation of the desorbent to a substantial degree, but batchwise or continuous regeneration can be further practiced to maintain active adsorbent by treatment with hydrogen peroxide or an organic peroxide.
