Is potassium gluconate harmful?
The JECFA database (the FAO/WHO expert committee) records an ADI of “not specified” (no numerical ADI is needed) for potassium gluconate, evaluated in 1998; this is a group ADI for glucono delta-lactone and the calcium, magnesium, potassium and sodium gluconates.
Is INS 577 permitted in Vietnam?
Yes. Potassium gluconate (INS 577) is listed in Appendix 1 of Circular 24/2019/TT-BYT, the list of additives permitted in food, with the function sequestrant and acidity regulator.
