Name in the List of Existing Food Additives
酵素処理イソクエルシトリン (No. 115)
Source and production
Obtained by adding glucose, using cyclodextrin glucosyltransferase, to a mixture of “ルチン酵素分解物” (enzymatic decomposition product of rutin) and starch or dextrin. The main component is α-glucosylisoquercitrin.

In Japan

  • An antioxidant made by attaching glucose with an enzyme to rutin that has been broken down with an enzyme (the enzymatic decomposition product of rutin). The main component is α-glucosylisoquercitrin (10th edition of Japan's Specifications and Standards for Food Additives). There are no standards for use.
  • When used as an antioxidant, the purpose name must be shown alongside. The simplified names “酵素処理ルチン” and “糖転移ルチン” are shared with the existing food additive enzymatically modified rutin (extract), so these simplified names alone do not show which one is meant.

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.
