In order to understand the dissolve material of instant noodle bowl in process of soaking， five kinds of instant noodle paper bowls purchased on the market were used as the research object， this paper measured the contents of styrene， vinyl chloride， ethylbenzene， toluene， xylene， cumene， bisphenol A， lead， cadmium and polychlorinated biphenyls in distilled water， 3% acetic acid， 10% ethanol and refined olive oil soaking solution of instant noodle paper bowl at different times. In addition， the changes of fluorescent agents and heavy metal ions were detected by stacking and rubbing experiments. And， 23 aromatic amines were detected by ink / binder transfer test. The results showed that only a small amount of lead and cadmium were dissolved in 3% acetic acid， 10% ethanol and refined olive oil， but they were lower than the limits standard of corresponding industry. The fluorescent agents were not detected， and the amounts of heavy metal ions chromium， arsenic， cadmium， mercury， lead detection were also lower than the industry limit in the stacking and rubbing experiments. 23 kinds of aromatic amine were not detected in the ink / adhesive migration test.
