Example of packaged food product
 

This tool help you to decide which information is required to demonstrate with simulation whether specific migration limits (SML) are not exceeded.
To modify the values defined below use the back button, to define a new product click "Packaged food product" in the menu bar.

SML value  
$SML$
mg/kg
mass of food  
$mF$
relative
mass of packaging material  
$mP$
relative
packaging thickness  
$lP$
$lPu$
product shelf life  
$shelf$
days

The maximum concentration in the packaging material (CP0) is now calculated according to complementary information, included in the form on the right. More information you add, higher the expected value of CP0 is.
 

 

 


max CP0 = $CP0$ mg/kg

property value unit/obs advice
Partition coefficient
qualitive
Select with care the appropriate condition (they are ordered from the most conservative to the lowest)
Diffusion coefficient
Introduce an overstimate of the diffusion coefficient (or leave it empty if you tkink that the thermodynamical equilibrium is reached)
Food texture
qualitative
Select with care the appropriate condition (they are ordered from the most conservative to the lowest)

HOW TO AUDIT YOUR PROVIDER
According to the information you have, your knowledge, the values you get from the bar menu (e.g. D overestimates or D estimates), modify the form above. Do not hesitate to test several options since all calculations are now in real time (the program uses precalculated data based on a dimensionless formulation).

You are compliant only if your choices are consistent with your application and if your provider can attest that the concentration in your packaging material is lower than max CP0.

 

 

 

Be aware that precalculated data are available only 120 min on our servers.
