Normal phase LC with gradient elution enabled the analysis of a broadened range of oligomers of BADGE (Bisphenol-A diglycidyl ether) and Novolak compounds in canned foods, such as sea foods in oil, meat products and soups. A major component released from Bisphenol-A resins was identified as the cyclo-(Bisphenol-A monoglycidyl ether) dimer and was commonly present in foods at concentrations of around 1 mg/kg. For the epoxy Novolaks, concentrations of the three- to six-ring compounds often far exceeded those of BFDGE (Bisphenol-F diglycidyl ether) and reached 20 mg/kg in foods. A two-step acylation is proposed for the detection of epoxy components.
具有梯度洗脱功能的正相液相色谱法能够分析罐装食品（如油浸海鲜、肉类产品和汤类）中双酚A二缩水甘油醚（BADGE）和酚醛清漆化合物的多种低聚物。双酚A树脂释放的一种主要成分被鉴定为环（双酚A单缩水甘油醚）二聚体，通常在食品中的浓度约为1毫克/千克。对于环氧酚醛清漆，三环至六环化合物的浓度常常远远超过双酚F二缩水甘油醚（BFDGE），在食品中可达20毫克/千克。本文提出了一种用于检测环氧成分的两步酰化法。
