Hello all, 

 

Need some guidance here.

 

I am trying to understand the criteria of a food grade chemical, in particular Sulfuric acid. I tried to access the FCC but its not free and is expensive. Can anyone please comment on what makes a sulfuric acid good grade? Are there any particular set of tests that need to be done to verify them?

 

Thanks!

 

Bidhan C.

Hello Bid,

They must meet the FCC monograph requirements, register with the FDA and all that entails (GMP's, etc), as well as meet the FDA's requirements for the GRAS declaration for that chemical.

And then of course YOU must meet the GRAS requirements in using it in a food grade application.

This is currently my bag, so I can go into more detail if needed.

Had to read through my subscription agreement. Unfortunately, it looks like they are pretty adamant about disclosing actual monograph info. That seems silly to me, but that's the way the cookie crumbles.

I figured as much, because I can't even give out the monograph for the product I produce, only a specification that says it matches the FCC monograph.

 

You are most likely going to either want to:

  • a) purchase a sub to food chemicals codex.org (it even says links can not be provided to this website, which to me is overkill since you can just do a dang google search to find it)
  • b) have your supplier attest that they meet or exceed the FCC monograph (we handle this on our specification and on some CoA's)

The monograph isn't just a simple spec, it will include (I'm reading this off of the mono so hopefully I'm not giving out more info than I'm allowed)

  • Description (lots of info here)
  • Function
  • Packaging and storage
  • Identification with acceptance criteria
  • Procedures to meet acceptance criteria
    • Assay, Inorganic impurities, limits,  and procedures on testing for those

FC Codex is usually "fairly" readily available in Technical Libraries. Together with other necessities such as AOAC.

 

Many of the "monographs" from a Food Grade POV consist of a statement defining Purity. The information is often, for overlapping content, "similar" IMEX to the US Pharmacopeia which performs a somewhat parallel function and may be more readily located.

 

IIRC, at one time FCC offered free access, just like the USP Fraud Database. Such is the cost of development.
