Hi All,

 

Does anyone know of a laboratory in North America ( e.g. USA, Canada etc.) that can test for the level of Dimethylpolysiloxane, an anti-foaming agent used in refined vegetable oils?

 

The laboratory we use cannot do the test and since this is a controlled additive we have to periodically verify the level. An online search for a suitable North American laboratory did not yield any satisfactory result.

 

Thanks.

I would start with Bureau Veritas in New York.  If they don't do it they will most likely be able to point you in the right direction.  Other choice might Intertek or UL, though getting good answers from UL has always been difficult for me.

Can I ask why you test for it?

 

It is a permissible food additive 21CFR173.340

 

Sorry, just curious. lol

Git-R-Done, though it's permissible, there is a maximum level allowed under CODEX. We just want to  confirm that we are within the permissible limits. Based on calculations, we know that we use less than required & regularly calibrate the scale but we have never done laboratory confirmation.

 

Thanks Snookie for the info. I will check out your suggestions.

If this test is really unusual then you may have to go to some of the bigger lab facilities in Hong Kong, but they are still run by BV, Intertek and UL.

My understanding is that there is a maximum allowable of >10000ppm

Not sure of labs as not my country but you can test for yourself fairly easily I believe.
