In Japan

  • A component obtained from the trunk, branches, and roots of hiba; its purpose in the List of Existing Food Additives is preservative. The specifications state that the dried product contains 98.0 to 102.0% β-thujaplicin.
  • No standards for use (the foods it can be used in or the maximum amounts) have been set.
  • Because it is a preservative, the purpose name is written alongside, as in “保存料(ヒノキチオール)” (preservative (hinokitiol)). The alternative name is “ヒノキチオール(抽出物)” (hinokitiol (extract)) and the short name is “ヒノキチオール” (hinokitiol).

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.
