摘　　要：按照金属三片罐的实际生产工艺,跟踪研究了制罐内涂、外涂、彩印、上光、罐内补涂以及全喷工序过程的中间品,各自相应内壁涂膜中9种双酚物向3%(m/v)乙酸和10%(v/v)乙醇模拟液中的迁移情况。结果表明:双酚F二环氧甘油醚及其衍生物在两种模拟液中都未检出;而双酚A-(2,3-二羟丙基)甘油醚和双酚A-双(2,3-二羟丙基)甘油醚在两种模拟液中均有迁出;10%乙醇中还检测到双酚A二环氧甘油醚及其他衍生物。在10%乙醇体系中,迁出的双酚物在全喷后增加显著。3%乙酸体系中,迁出的双酚物在补涂和全喷后增加明显。结果表明补涂与全喷这两个工艺对三片罐的食品安全性造成潜在影响,可在加工过程中作为关键控制点进行控制。The migration of nine kinds of bisphenol compounds from respective inner coating of intermediate product to 3% （m/v） acetic acid and 10% （v/v） ethanol after internal surface coating,external surface coating, color printing ,varnishing, supplementary coating and full spraying of cans according to the practical production process of three-piece metal cans was studied. It was found that bisphenol F diglycidyl ether and its derivatives were not detected in both two simulated solutions ,whereas bisphenol A（2,3-dihydroxypropyl） glycidyl ether and bisphenol A bis（2,3-dihydroxypropyl） glycidyl ether were detected in both simulated solutions. Moreover,bisphenol A（3-chloro-2-hydroxypropyl） glycidyl ether and other derivatives were also detected in 10% ethanol system,and the contents of all these detected bisphenol compounds increased significantly after full spraying of cans. Meanwhile ,the contents of these compounds also remarkably increased after supplementary coating and full spraying of cans in 3% acetic acid system. The results suggested the two processing points including supplementary coating and full spraying of cans had potential impacts on the safety of inner coatings ,which were deemed as key control points.
