α-Glucosyltransferase / 4-α-Glucanotransferase / 6-α-Glucanotransferase α-グルコシルトランスフェラーゼ

Existing food additiveEU: covered by the food enzymes rules

Purpose: enzyme
On the label: “酵素” (enzyme), “α-グルコシルトランスフェラーゼ” (α-glucosyltransferase), “4-α-グルカノトランスフェラーゼ” (4-α-glucanotransferase), “6-α-グルカノトランスフェラーゼ” (6-α-glucanotransferase)
Name in the List of Existing Food Additives: α-グルコシルトランスフェラーゼ (No. 100)
Source and production: An enzyme that transfers glucosyl groups or glucan chains, obtained from potato tubers, or from cultures of actinomycetes (Streptomyces) or bacteria (Bacillus and others) (the specifications and standards limit the species that can be used).

In Japan

α-Glucosyltransferase (alternative names: 4-α-glucanotransferase, 6-α-glucanotransferase) is an enzyme that moves glucose units (glucosyl groups) or glucan chains onto other molecules. It is used to make enzymatically modified stevia (definition in the specifications and standards).
It falls within the group name “酵素” (enzyme); if it stays active and has an effect in the final food, it can be written together as “酵素”. If it counts as a processing aid, for example because it is inactivated or removed during manufacturing, it is exempt from labeling.
There are no standards for use.

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

In the EU, food enzymes are covered by the food enzymes regulation (Regulation (EC) No 1332/2008), not by the list of food additives (Regulation (EC) No 1333/2008, Annex II).

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.
