Is Lactic Acid (E270) Halal?
E270 (Lactic Acid) is listed as doubtful by MUIS — its source can vary, so verify before consuming.
Why is E270 doubtful?
Lactic acid is produced by fermenting sugars with lactic-acid bacteria. The acid itself contains no animal material, but the fermentation medium can include whey or other animal-derived nutrients and the E-number does not identify the producer, so MUIS lists it as doubtful. Lactic acid from the major manufacturers is commonly halal-certified.
