| Abstract: | Chemical substances such as additives,monomer,oligomer and decomposed products migrating from plastic packaging materials may be instable in food(simulants),which will directly affect the veracity and reliability of migration testing results.Research on migrants stability is summarized and instability theory of migrants is advanced.MigraSoft 2006,a software developed by MATLAB using Finite Difference Method for predicting migration,is utilized to simulate instability of chemical migrants in foods(simulants) numerically. |
