In Japan

  • Its main components are tannin and tannic acid, obtained from persimmon fruit, Chinese gallnut, oak gall, mimosa bark, and similar sources. Its purpose in the List of Existing Food Additives is processing agent.
  • It is divided into persimmon tannin, plant tannin, and mimosa tannin; persimmon tannin can also be written under the alternative names “柿渋” (kakishibu) or “柿抽出物” (persimmon extract).
  • There is no group name for processing agents, so it is labeled by substance name (short names such as “タンニン” (tannin) and “タンニン酸” (tannic acid)).

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.

This page lists facts stated in laws and in evaluations by public bodies; it is not a safety verdict. Additives used in Japan are approved by the government, which sets the foods and amounts they can be used in. The ADI is a guide to the amount that is considered safe to take every day over a lifetime.
