Fructosyl Transferase フルクト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), “フルクトシルトランスフェラーゼ” (fructosyl transferase)
Name in the List of Existing Food Additives: フルクトシルトランスフェラーゼ (No. 244)
Source and production: An enzyme that transfers the fructosyl group of sugars, obtained from cultures of filamentous fungi (genus Aspergillus, genus Aureobasidium, Penicillium roqueforti) or bacteria (genus Arthrobacter, genus Bacillus, and others).

In Japan

An enzyme obtained from cultures of filamentous fungi or bacteria that moves the fructosyl group of a sugar to another sugar (as defined in the Japanese Standards of Food Additives). There are no standards for use.
It falls within the scope of the group name “酵素” (enzyme), and if it is not inactivated and its effect remains in the final food, it can be written together as “酵素” (enzyme). If it counts as a processing aid, for example because it is inactivated or removed during manufacturing, labeling is exempt (Food Labeling Standards).

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.
