Is E330 (Citric acid) Halal?
Generally halal
E330 (Citric acid) is produced by microbial fermentation of plant sugars and is generally considered halal; a strict check would confirm the fermentation medium.
What is E330?
Citric acid is a sour-tasting acid used to adjust acidity, add tartness and preserve freshness. Although it occurs naturally in citrus fruit, commercial citric acid is made by fermenting sugars with the mould Aspergillus niger.
Produced by fermenting a carbohydrate (often corn/glucose) with the mould Aspergillus niger, then purified. The process is plant- and microbe-based.
Why is it generally halal?
Citric acid is generally classified as halal because it is produced by microbial fermentation of plant sugars, with no animal or alcohol component. A small number of strict bodies ask about the fermentation medium and processing aids; for full certainty, look for certification. The finished product still needs its own verification.
