Is L-Glutamic Acid (E620) Halal?
E620 (L-Glutamic Acid) is listed as doubtful by MUIS — its source can vary, so verify before consuming.
Why is E620 doubtful?
Glutamic acid is the parent acid of MSG (E621) and is made the same way, by fermenting plant sugars with bacteria. MUIS lists it as doubtful because the fermentation medium and processing aids vary by manufacturer and are not identified by the E-number. A halal logo on the finished product is the reliable check.
