Use of Sodium trimetaphosphate in food processing

My company is thinking to add Sodium trimetaphosphate in fish product to retain water for better mouth feel. But I cannot find any related regulatory or standard for reference/guideline.

 

So, do anyone know if there is INS/E-number for Sodium trimetaphosphate? I can only find INS number for sodium phosphate.

 

Any Codex guidline on this one?

 

Many thanks.

Hi, Jackson;

 

Sodium phosphates (listed as INS E339) is a very generic term and most derivatives (di/tri/poly/meta) are used in food processing.  If you're unable to find GRAS with the EU I would suggest sourcing a more common derivative such as tripoly or metabi (as long as they serve the same purpose).  Or perhaps the purchasing agent(s) in EU that can assist with regulation?

 

Here are some attachments from CA in this order that I could find on the topic;
 

CXS_166e (fish "portions" et al as modified starches)

 

AL70_20e (limitations as modified by esterification)

 

Dear Jackson Tsang,

 

You should be aware that some countries ban the use of this technique, at any level.

Thanks mates. I am able to find the GRAS status of sodium trimetaphosphate from FDA.

Any example of the country banning the use of it as a reference?

Thanks.

Just for starters -

PS - and yes, Codex does have some restrictive viewpoints on the adding of various phosphates to certain seafood products. From memory it proposes a maximum limit of (total) Phosphorus content in the finished product.

The article I'm familiar with, and deduction is inconclusive for GRAS specifically for this form of phosphates (and it's somewhat dated).  

I am in no measure a chemist nor nutritionist, but I would not take that FDA article for a grain of  Na₂S₂O_{5  :biggrin:} 

 

Additionally it should be declared on packaging.
