Regulatory evidence across markets

None of the 13 markets tracked here holds an imported rule under the name POTASSIUM BITARTRATE.

That is a statement about this inventory, not about the law: no imported rule is not evidence that a substance is permitted. A rule may exist under a different name, under a CAS or EC number this glossary entry does not carry, or in a dataset not yet imported.

Potassium Bitartrate

Potassium bitartrate is an organic potassium salt of L-tartaric acid. It is a by-product of winemaking and occurs naturally in grapes, the major fruit used to produce wine. It has a role as an antimicrobial agent, a laxative, a food acidity regulator, a plant metabolite, a food anticaking agent, a food stabiliser, a food humectant and a raising agent. It contains a L-tartrate(1-). — ChEBI
