How much is permitted

A listing usually limits the quantity as well as the food. Only one of the forms that takes is a figure: quantum satis and good manufacturing practice permit the amount the technological effect requires and no more, which is a limit rather than the absence of one. Figures below are the range across every food category this page is listed in, and categories differ between regulators — see how much is permitted.

European Union2,000 mg/kg – 4,000 mg/kg4 numeric limit, 46 several limits, 19 quantum satis, 23 no quantity stated

What FDA’s inventory records

This page holds no listing for Disodium citrate in the parts of 21 CFR this site reads. FDA’s Substances Added to Food inventory does carry it, as DISODIUM CITRATE, pointing at a food-contact regulation, not a listing for use in food: 21 CFR 181.29.

Technical effects FDA records: stabilizer or thickener.

The inventory is an information resource: a row means FDA holds information about the substance’s use in food, not that the substance is listed for that use. It is shown apart from the permissions above and is not counted as a US permission anywhere on this site.
