According to numerous, even recent studies, trans fatty acids (TFA) are related to coronary heart disease. Thus, for the evaluation of the daily TFA-intake precise data on the content of TFA in currently available edible fats are of great interest. The present study gives a comprehensive overview on total trans-octadecenoic acid contents in 93 brands of German margarines, shortenings, cooking and dietary fats purchases in 1994, that were obtained by a two-dimensional chromatography method (Ag-TLC/GC). Conventional margarines were found to contain 0.17-25.90 wt% (n = 46) and shortenings/cooking fats 0.04-32.51 wt% (n = 16) TFA related to total fatty acids. Mean values were 9.32 resp. 9.79%, whereas dietary and reformatory fats exhibited a mean of 0.65% (n = 31) TFA. Among conventional margarines the highest TFA contents were detected in products (n = 11) derived exclusively from sunflower oil (mean value = 20.71%). Seasonal changes in single brands were relatively small.
根据众多甚至是近期的研究，反式脂肪酸（TFA）与冠心病有关。因此，为了评估每日反式脂肪酸摄入量，目前市售食用脂肪中反式脂肪酸含量的精确数据备受关注。本研究全面概述了1994年购买的93个德国品牌人造黄油、起酥油、烹饪油和食用油脂中的总反式十八碳烯酸含量，这些数据是通过二维色谱法（银薄层色谱/气相色谱法，Ag-TLC/GC）获得的。结果发现，传统人造黄油中反式脂肪酸含量占总脂肪酸的0.17 - 25.90 wt%（n = 46），起酥油/烹饪油中为0.04 - 32.51 wt%（n = 16）。平均值分别为9.32%和9.79%，而食用油脂和改良油脂的反式脂肪酸平均含量为0.65%（n = 31）。在传统人造黄油中，仅由葵花籽油制成的产品（n = 11）中反式脂肪酸含量最高（平均值 = 20.71%）。单个品牌的季节性变化相对较小。
