In Japan

  • The roots of tororoaoi, a plant of the mallow family, dried and made into powder. The main component is polysaccharides, and its purpose in the list of items in the List of Existing Food Additives is thickening stabilizer.
  • When used for thickening, stabilizing, or gelling, it must be written together with its purpose name, such as “増粘剤（トロロアオイ）” (thickener (tororoaoi)). There are no standards for use.

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.

When it is labeled under a shared name

Tororoaoi may be declared on the label in the same way as “増粘剤・安定剤・ゲル化剤”. See Thickener / stabilizer / gelling agent for details.
