Source and production
Obtained by hydrolyzing with enzymes the nucleic acids extracted with water, in the presence of salt, from the cells of yeast (Candida utilis), then separating the product. The component is 5'-cytidylic acid.

In Japan

  • 5'-Cytidylic acid, obtained by breaking down nucleic acids taken from yeast with enzymes (Japan's Specifications and Standards for Food Additives). Its purpose in the List of Existing Food Additives is “強化剤” (nutrient fortifier). There are no standards for use.
  • The short name used on labels is “5'-CMP”. The designated additive “5'-シチジル酸二ナトリウム” (disodium 5'-cytidylate) is a separate item.

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

  • It is not on the EU list of food additives (Regulation (EC) No 1333/2008, Annex II), so it cannot be used as a food additive in the EU.

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.
