Is hydrochloric acid harmful?
In 2019 EFSA concluded that exposure to chloride from hydrochloric acid and its potassium, calcium and magnesium salts (E507, E508, E509, E511) does not raise a safety concern at the reported use levels. EFSA used a reference value of 40 mg chloride/kg body weight per day: mean exposure in all age groups was at or below it, while 95th percentile exposure in toddlers, children and adolescents was slightly above it. The main contributors are processed fruit and vegetables, confectionery, flavoured drinks and sauces.
Is E507 permitted in Vietnam?
Yes. Hydrochloric acid (INS 507) is listed in Appendix 1 of Circular 24/2019/TT-BYT, the list of additives permitted in food.
Can children and pregnant women have E507?
According to EFSA (2019), hydrochloric acid (E507) is authorised in processed cereal-based foods and baby foods for infants and young children (category 13.1.3, only for pH adjustment), in other foods for young children (13.1.4, only for pH adjustment) and in dietary foods for special medical purposes for infants below 16 weeks of age (13.1.5.1). Because industry gave no use levels for 13.1.5.1, EFSA could not assess exposure or the safety of this use. If you have a particular health condition, ask a doctor.
