The IUPAC Commission on Oils, Fats and Derivatives undertook development of a method and collaborative study for determination of polymerized triglycerides in oils and fats. Two collaborative studies were carried out by IUPAC in 1985 and 1986. Both studies consisted of 4 materials, including animal fat, frying oil with average content of polymers, and blends of frying oil containing varying amounts of polymers. Thirteen and 17 laboratories were included in the first and second IUPAC collaborative studies, respectively. Another collaborative study conducted by inspectorate for Health Protection, Food Inspection Service, The Netherlands, included 13 laboratories. Six heat-processed fat samples (3 pairs of split samples) containing 14-28% (w/w) of polymerized triglycerides were studied. The method was adopted by AOAC INTERNATIONAL as an IUPAC-AOCS-AOAC method.
国际纯粹与应用化学联合会（IUPAC）油脂及衍生物委员会开展了一项测定油脂中聚合甘油三酯的方法开发及协作研究。IUPAC在1985年和1986年进行了两项协作研究。两项研究均包含4种材料，包括动物脂肪、聚合物平均含量的煎炸油以及含有不同聚合物含量的煎炸油混合物。IUPAC的首次和第二次协作研究分别有13个和17个实验室参与。荷兰卫生保护检查局进行的另一项协作研究有13个实验室参与。研究了6个含有14 - 28%（w/w）聚合甘油三酯的热加工脂肪样品（3对分割样品）。该方法被美国官方分析化学师协会（AOAC INTERNATIONAL）采用为IUPAC - AOCS - AOAC方法。
