Maltotriohydrolase マルトトリオヒドロラーゼ

Existing food additiveEU: covered by the food enzymes rules

Purpose: enzyme
On the label: “酵素” (enzyme; the group name used when the enzyme stays active and has an effect in the final food), not labeled when it counts as a processing aid, “アミラーゼ” (amylase) or “カルボヒドラーゼ” (carbohydrase) when written by substance name
Name in the List of Existing Food Additives: マルトトリオヒドロラーゼ (No. 283)
Source and production: An enzyme obtained from cultures of filamentous fungi (limited to the genus Penicillium), actinomycetes (limited to five species of the genus Streptomyces), or bacteria (limited to Bacillus subtilis, Cellulosimicrobium cellulans, and the genus Microbacterium) that hydrolyzes starch and similar substances to produce maltotriose (definition in the specifications).

In Japan

An enzyme obtained from cultures of filamentous fungi, actinomycetes, and bacteria that breaks down starch and similar substances to make maltotriose (a sugar made of three glucose units) (Specifications and Standards for Food Additives, 10th edition). Its alternative name is “G3生成酵素” (G3-producing enzyme), and its short names are “アミラーゼ” (amylase) and “カルボヒドラーゼ” (carbohydrase).
There are no standards for use. If it stays active and has an effect in the final food, it can be written under the group name “酵素” (enzyme), but labeling is exempt when it counts as a processing aid (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.
