This is a summary of the standards for use. See the source list for the exact conditions.

In the EU

  • In the EU, flavoring substances are covered by the flavorings regulation (Regulation (EC) No 1334/2008), not by the list of food additives. It is on the Union list of flavoring substances (Annex I) as FL 12.025.
  • In 2010, EFSA evaluated a proposal to use it as a food additive for preventing spoilage and set an ADI of about 0.02 mg per kg of body weight per day. It pointed out that average intake from naturally occurring amounts in food, flavoring use, and the spoilage-prevention use combined would be 2 to 4 times the ADI in children.
  • In its 2010 evaluation, EFSA (the European Food Safety Authority) set an ADI (acceptable daily intake) of 約0.02mg per kg of body weight per day (EFSA ANS).

When it is labeled under a shared name

Allyl Isothiocyanate (Volatile Oil of Mustard) may be declared on the label in the same way as “香料”. See Flavoring for details.
