食品印刷包装纸中的光引发剂Irgacure-184会向食品中迁移，建立了用气相色谱法检测被污染的奶粉中Irgacure-184的方法，并研究了在高温条件下，纸中Irgacure-184向奶粉迁移的行为。结果表明：温度越高，迁移速度越快，越容易在短时间内达到平衡，且总迁移量越大。

Printed paper packaging for food usually contain the photoinitiator like Irgacure-184, which can migrate into the packaged food. A new gas chromatographic method was established to detect the content of Irgacure-184 in contaminated milk. Migration behavior of Irgacure-184 to milk powder at high temperature was investigated. The result showed that migration speed increases with temperature increase and it is easier to reach equilibrium with larger total migration amount.
