Hi All - first post on IFSQN.

 

I have a query regarding migration testing for food contact packaging, currently we are using butter to detect a taint. We are leaving this for 72hrs before we test (organoleptic - taste/smell).  

 

I'd like to know more about migration tests and how I could improve our process;

 

  • Is this the most cost effective way?
  • Can I reduce the time down from 72hrs?

 

Feel free to share your thoughts, suggestions and experiences.

 

Thanks.

Hello arctic and welcome to the IFSQN.  When you use the word "migration" in confuses me.  These day's migration testing of food packaging is a whole different ball-game and is scientific chemical analysis conducted by an accredited laboratory to defined EU regulations.

 

What you are doing is taste and odour testing to see if the packaging taints your product.

 

If the packaging is purchased as suitable for your product and process to an agreed specification and you have conducted perhaps initial validation tests then why do you need ongoing tests?  Have you had problems? What do you find? What kind of taint?  What is your product?

 

Maybe you can reduce the frequency or get rid of it altogether.

Hi Simon,

 

Yes - we are testing each new supplier batch of printed food contact packaging for taint.

 

Our suppliers have indicated they do not carry out such tests after the printing process has been completed. We have had issues in the past depending on the process of printing which is carried out, and we have continued to use this method for a number of years.

 

Our product is salmon.

The company I work for is not large by any stretch of the imagination and our packages do have a fair amount of printing.  We carry out the extensive lab testing for all of the requirements such as migration testing, but also sensory testing that you are speaking of.  In the end it does not add that much to our costs and provides a lot of benefit to both ourselves and our customers.  If you are working with a laboratory they may be able to help with a proper procedure.  I utilize the same procedures that our lab uses to model my SOP's on so we are utilizing the same standard and I can pick up any possible issues before I send to the lab.

Make sure your printer is using low migration inks / varnish / adhesives and that the substrate is suitable for food contact.

They should also be operating to Good Manufacturing Practice as per EU reg 2023/2006.

Carry out a risk assessment on the final pack. 

You may not need to go to the expense of migration testing.
