Is E321 halal? The verdict
E321 is mashbooh (doubtful). Synthetic antioxidant with no animal-derived ingredient. The halal additive listing the app follows marks it doubtful over its manufacturing process, so treat it as doubtful unless the product is halal-certified. Manufacturers aren't required to print the source on the label, so unless the pack states a plant/vegetable source or carries a recognised halal certification (HMC, JAKIM, MUI, IFANCA), the safest choice is to avoid it.

Scan the ingredient list for E321 and its other names. If it's present and the source isn't stated, treat the product as doubtful. A barcode or photo scan with Halal Food AI flags E321 automatically and tells you whether the product declares a halal source.
