Xylanase キシラナーゼ

Existing food additiveEU: covered by the food enzymes rules

Purpose: enzyme
On the label: “酵素” (enzyme), “キシラナーゼ” (xylanase)
Name in the List of Existing Food Additives: キシラナーゼ (No. 77)
Source and production: An enzyme that breaks down xylan, obtained from cultures of filamentous fungi (such as the genera Aspergillus and Trichoderma) or actinomycetes (the genus Streptomyces). The specifications limit which microorganisms can be used.

In Japan

Xylanase is an enzyme that breaks down xylan, which is found in plant cell walls and elsewhere. It is used in food manufacturing and processing for its catalytic action.
It falls within the group name “酵素” (enzyme), and if it stays active and has an effect 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.
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.
