Encapsulated health food oils such as fish oils are readily available in health food stores, pharmacies, and supermarkets. They are popular in the United States as well as in the European countries. However, such oils, because of their high degree of unsaturation, are easily oxidized and form complex mixtures of high molecular weight oxidation products. The present work reports the application of high-performance size exclusion chromatography to the determination of these materials in encapsulated fish oils. Of the six samples studied, five showed from 1-10% of dimeric triacylglycerols and one contained 6.3% trimeric triacylglycerols and 3.1% oligomeric triacylglycerols. Further investigation of this sample with silicic acid chromatography indicated that it contained a total of 36.3% polar material.
诸如鱼油之类的胶囊装保健食品油在保健食品商店、药店和超市中很容易买到。它们在美国以及欧洲国家都很受欢迎。然而，这类油由于不饱和度高，很容易被氧化，形成高分子量氧化产物的复杂混合物。本研究报告了高效尺寸排阻色谱法在测定胶囊装鱼油中这些物质的应用。在所研究的六个样品中，五个含有1%至10%的二聚甘油三酯，一个含有6.3%的三聚甘油三酯和3.1%的低聚甘油三酯。用硅酸色谱法对该样品进行的进一步研究表明，它总共含有36.3%的极性物质。
