In Japan

  • An emulsifier whose main component is saponin, obtained from the bark of quillaia.
  • It falls within the range of the group name for emulsifiers, and when used for emulsification it can be labeled simply as “乳化剤” (emulsifier). When written by substance name, the other name “キラヤサポニン” (quillaia saponin) and the simplified name “サポニン” (saponin) can also be used.

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 on the EU list of food additives (Regulation (EC) No 1333/2008, Annex II) as E999.
  • EFSA's ADI (3 mg per kg of body weight per day) is expressed as the amount converted to saponin. The ADI was maintained in a follow-up evaluation in 2024.
  • In its 2019 evaluation, EFSA (the European Food Safety Authority) set an ADI (acceptable daily intake) of 3mg（サポニンとして） per kg of body weight per day (EFSA FAF).

When it is labeled under a shared name

Quillaia Extract may be declared on the label in the same way as “乳化剤”. See Emulsifier for details.

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.
