Sodium Caseinate カゼインナトリウム

In Japan

• The sodium salt of casein, a milk protein, and a designated additive. There are no standards for use (rules on which foods it may be used in or how much).
• It is labeled by its substance name or by the short name “カゼインNa” (sodium caseinate) (CAA, Annex to the Food Labeling Standards explanatory notice).
• Because it is made from milk, allergen labeling writes it as “カゼインNa（乳由来）” (sodium caseinate (derived from milk)).
• The list of standards for use has no purpose category for it, and in the CAA annex it is not included in the range of the group name for emulsifiers, nor in the list of additives for which the purpose name is written alongside as a thickener or “糊料” (thickening agent).

Japan's standards for use

There are no standards for use that limit which foods or how much (the general standards for all additives still apply).

This is a summary of the standards for use. See the source list for the exact conditions.

In the EU

• It is not on the EU list of food additives (Regulation (EC) No 1333/2008, Annex II), so it cannot be used as a food additive in the EU.
• In the EU, caseinates are treated as food (an ingredient), not as food additives, and have no E number. The specifications for the components are set in EU Directive 2015/2203.
