Phosphodiesterase ホスホジエステラーゼ

Existing food additiveEU: covered by the food enzymes rules
Purpose
enzyme
On the label
“酵素” (enzyme), “ホスホジエステラーゼ” (phosphodiesterase)
Name in the List of Existing Food Additives
ホスホジエステラーゼ (No. 273)
Source and production
An enzyme that hydrolyzes phosphodiester bonds in nucleic acids and similar substances, obtained from cultures of filamentous fungi (3 species, such as Aspergillus niger) or actinomycetes (6 species of the genus Streptomyces) (definition in the specifications).

In Japan

  • An enzyme that breaks down phosphodiester bonds in nucleic acids and similar substances. The specifications state that it is obtained from cultures of specific filamentous fungi and actinomycetes.
  • No standards for use (the foods it can be used in or the maximum amounts) have been set.
  • It falls within the group name for enzymes, so it can be labeled together as “酵素” (enzyme). When it counts as a processing aid, for example because it is used during manufacturing and does not remain in the final food, labeling is exempt.

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.
