Why this verdict

E621 is monosodium glutamate (MSG), the most widely used flavour enhancer, found in savoury snacks, instant noodles, sauces, and seasonings. SANHA classifies E621 as halal, and JAKIM permitted it in 2014 (Muzakarah Council 105), ruling the purified final product halal. MUIS marks E621 as syubhah, noting it is the sodium salt of glutamic acid (E620). On the classification of SANHA and JAKIM, E621 is halal.

Food-safety note
Permitted as a flavour enhancer in Australia and New Zealand under the Food Standards Code (Schedule 15). Glutamate occurs naturally in many foods such as tomatoes and cheese; FSANZ reviewed the so-called "MSG symptom complex" and found no consistent evidence that MSG causes the reactions sometimes attributed to it. (Source: FSANZ; Food Standards Code Schedule 15.)
