| Abstract: | The mathematics model and simulation model to predict migration of additives from plastics packaging materials to food were established applied finite element method.Based on migration of BHT to stimulant food,diffusion during extrusion and storage of plastics and reverse diffusion to plastics by food were analyzed.The models can be utilized to predict migration of additives having mixed boundary conditions,developed as a total solution food package for migration problems,predigested research quomodo. |
| Keywords: | food packaging plastic migration simulation additive |
