Questions about propionic acid
Is propionic acid harmful?
In 2014 EFSA re-evaluated propionic acid and its sodium, calcium and potassium salts (E280–E283) and concluded that the present database did not allow an ADI to be allocated. EFSA estimated exposure from food additive use at 0.7–21.1 mg/kg body weight a day at the mean and 3.6–40.8 mg/kg at the 95th percentile. EFSA concluded that for food as consumed there would not be a safety concern from the maximum concentrations of propionic acid and its salts at their currently authorised uses and use levels.
Is E280 permitted in Vietnam?
Yes. Propionic acid (INS 280) is listed in Appendix 1 of Circular 24/2019/TT-BYT, the list of additives permitted in food, as a preservative.
