Questions about ammonium phosphatides
Is ammonium phosphatide harmful?
In 2016, re-evaluating ammonium phosphatides (E 442), EFSA concluded there is no reason to revise the current ADI of 30 mg/kg body weight per day. Since the ADI is not exceeded in any population group, EFSA concluded that use of E 442 at the permitted or reported use levels would not be of safety concern.
Is INS 442 permitted in Vietnam?
Yes. Ammonium salts of phosphatidic acid (INS 442) is listed in Appendix 1 of Circular 24/2019/TT-BYT, the list of additives permitted in food.
