采用气液薄层色谱法和银离子薄层色谱法对奥地利、比利时、捷克、丹麦、芬兰、匈牙利、日本、挪威、波兰、瑞典和美国等国市场销售的人造黄油中的反式脂肪酸含量进行了测定。反式脂肪酸占总脂肪酸的wt%，在奥地利、芬兰、匈牙利和瑞典的大多数人造黄油产品中，反式脂肪酸的含量低于3%。比利时产品的反式脂肪酸含量相对较低，平均为4%。捷克共和国和丹麦将反式脂肪酸分为低于2%和高于20%两组。在日本、挪威、波兰和美国，反式脂肪酸含量超过20%。在奥地利、比利时、捷克、丹麦、芬兰、匈牙利和瑞典，人造黄油的反式脂肪酸含量普遍低于3%。日本、挪威、波兰和美国表示，反式脂肪酸的平均含量相对较高，为13-16%，尽管在这些国家的市场上出现了几种低反式脂肪酸人造黄油（低于3%）。在大多数情况下，低反式脂肪酸的人造黄油富含饱和脂肪酸，高反式脂肪酸和低反式脂肪酸的人造黄油反式脂肪酸和饱和脂肪酸的总价值（TFA+SFA）基本相同。总顺式多不饱和脂肪酸（PUFA）与TFA+SFA之比[PUFA/(TFA+SFA)]大于1的人造黄油在丹麦作为印刷人造黄油出售，在除瑞典以外的所有其他国家作为桶装人造黄油出售。美国人造黄油中TFA+SFA的含量（g/100g）很低，而日本人造黄油中TFA+SFA的含量很高。
Determination was made of trans fatty acid content in margarines marketed in Austria, Belgium, Czech Republic, Denmark, Finland, Hungary, Japan, Norway, Poland, Sweden and the United States by gas-liquid and silver-ion thin-layer chromatography carried out in conjunction. As wt% of total fatty acid, it was found that, in print margarines, trans fatty acid was less than 3% in most products of Austria, Finland, Hungary and Sweden. For products of Belgium, trans fatty acid was relatively low, at 4% on the average. In Czech Republic and Denmark, trans fatty acid was divided into two groups of less than 2% and 20% or more. In Japan, Norway, Poland and the United States, trans fatty acid was found to exceed 20%. In tub margarines, trans fatty acid was generally below 3% for Austria, Belgium, Czech Republic, Denmark, Finland, Hungary and Sweden. Japan, Norway, Poland and the United States indicated mean trans fatty acid to be relatively high, at 13-16%, though several brands of low trans fatty acid margarines (below 3%) appear on the market in these countries. In most cases, margarines low in trans fatty acid were rich in saturated fatty acid and the total value of trans and saturated fatty acids (TFA+SFA) was essentially the same in high and low trans fatty acid margarines. Margarines with total cis-polyunsaturated fatty acid (PUFA) to TFA+SFA ratio [PUFA/(TFA+SFA)], above 1, are available as print margarines in Denmark and tub margarines in all the other countries except for Sweden. TFA+SFA content (g/100g) in print margarines in the United States was quite low and tub margarines in Japan were noted to contain considerable TFA+SFA.
