**3. Food-packaging interaction testing**

The most important quality of packaging materials is to provide protection to the food by providing enclosure which provide total barrier to external impact. As seen above, food-package interaction follows different pattern and offered several detrimental effect to the food quality/integrity. Packaging testing is necessary step in package selection to ensure that applicable packaging material is used. Quality testing as well as testing to measure the amount of interacting substance in a packaging system is very important for the manufacturer to ensure that standard packaged are employed for enclosure of the food and also to make sure that packaging material has negligible effect on the final product getting the consumer and it does not cause any negative impact on health after consumption of the packed food material. For the detection and analysis of the interacting components in a packaging system the following system are employed (i) simulants (ii) mathematical models (iii) predictive models and (iv) analytical/chromatographic techniques are used.
