The principle of a computing program describing precisely the migration of additives from a polymer into a food simulant is presented. As six parameters are used to fit the simulnnt sorption and additive extraction kinetics, the parameters have been determined by independent experiments. Owing to the complicated coupling between the liquid and additive diffusion processes, migration kinetics ca...

A food additive is any substance added to food primarily for preservation purposes and the consumer demands for a variety of safe and tasty, convenient and colourful foods. Additives and preservatives have been used for a very long time and contributed significantly to product development by the food industry. Despite the advances in the field of product development, some consumers have real co...
