Is calcium lactate harmful?

The JECFA database (the FAO/WHO expert committee) records an ADI of “not limited” for calcium lactate, evaluated in 1974; the same ADI is also recorded from 1973.

Is INS 327 permitted in Vietnam?

Yes. Calcium lactate (INS 327) is listed in Appendix 1 of Circular 24/2019/TT-BYT, the list of additives permitted in food, as an acidity regulator, emulsifying salt, flour treatment agent, firming agent and thickener.
