Existing food additivePermitted in the EU (E459)

Purpose: processing agent
On the label: “シクロデキストリン” (cyclodextrin), “サイクロデキストリン” (cyclodextrin), “環状オリゴ糖” (cyclic oligosaccharide)
Name in the List of Existing Food Additives: シクロデキストリン (No. 143)
Source and production: Obtained by treating starch with enzymes, as non-reducing cyclic dextrins. There are α, β, and γ types (rings of 6, 7, and 8 D-glucose units) and branched cyclodextrins.

In Japan

A cyclic oligosaccharide, in which glucose units are linked in a ring, obtained by treating starch with enzymes. There are α (6 units), β (7 units), and γ (8 units) types, and branched cyclodextrins (Japanese Standards of Food Additives). Its purpose in the List of Existing Food Additives is manufacturing agent. There are no standards for use.
It can be labeled as “シクロデキストリン” (cyclodextrin), its other name “サイクロデキストリン” (cyclodextrin), or its short name “環状オリゴ糖” (cyclic oligosaccharide).

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 E459.
The EU additive list includes only β-cyclodextrin (E459); α- and γ-cyclodextrin are not listed.

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.
