The Vietnam National Codex Committee affirmed Thursday that tartrazine - a synthetic lemon yellow azo dye used as a food coloring - is allowed under FAO/WHO Food Standards.
Codex Vietnam made the statement after local media recently raised questions about possible health effects of the yellow coloring (known as E102).
The agency said the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) had established an acceptable daily intake of 0-7.5 mg/kg bw/day for E102.
The US, the EU and other Southeast Asian countries also allow E102 in food, it added.
E102 attracted public attention in Vietnam after a TV commercial early this month released a message that dark-colored instant noodles may be more harmful than bright-colored ones.
Local newspapers and websites later chipped in and ran stories implying negative health effects of food coloring used in instant noodles and other food products.
