It seems that in order to produce food, I need to have food grade chemicals. How unexpected.

As I can see, the best source for food-grade definition is the FCC (food chemicals codex), but the book is quite heavy and expensive. Do anyone knows a source for food grade specifications for chemicals?

Dear Itay.sh

The requirement will perhaps depend on the chemical which is ??

@ FSSM
Very useful links indeed.

I tested the additives database with orthophosphate, hydrochloric acid and sodium chloride. Only got no hit with the last one which is rather surprising.

The first two gave impressive data although the heavy metal impurities seemed to be primarily restricted to lead and arsenic (the reason is probably explained in the text given time to browse).

To answer the original request, there are some published alternative sources of data, eg USP Pharmacoepia but probably not cheap also. Most people head to a library.

There is also a thread on the subject of locating / buying food-grade chemicals somewhere on this forum (initially relating to sourcing NaOH from memory) if you are willing to do a bit of searching.

Ok, sorry now I get what kind of chemicals we are talking about.

Dear Charles.C you are right just could find potassium chloride (INS 508).

Also check this link, might help for some other searching tasks:

Hydrochloric acid (INS 507),
Sodium hydroxide (INS 524),
Acetic acid, glacial (INS 260),
Ammonium hydroxide (INS 527) in solution CAS number 1336-21-6.

itay.sh, what other chemicals do you need?

Hi itay.sh

I am not clear if you are looking for food grade cleaning chemicals or food chemical additives?

In either case your supplier should provide you with comprehensive specifications.
