Is E640 Halal?
E640 (Glycine and its Sodium Salt) is classified as mashbooh — doubtful. It is an amino acid that can be made synthetically or derived from gelatine, so it can be halal or haram depending on the source used, and the label doesn't say which.
Why is E640 mashbooh (doubtful)?
An amino acid that can be made synthetically or derived from gelatine. When an additive can come from either a permissible source (plant or synthetic) or a prohibited or unverified animal source, Islamic scholars classify it as mashbooh and advise Muslims to verify before consuming. The Prophet's guidance to leave what is doubtful is the basis of this cautious approach.
Frequently Asked Questions
Is E640 permissible in Islam?
It depends on the source. Plant-derived or synthetic E640 is permissible; animal-derived E640 is only permissible if from a halal-slaughtered animal. Since labels don't distinguish, it is treated as doubtful.
How do I know if E640 in a product is halal-certified?
Look for a halal certification logo on the packaging from a recognised halal certifying body. If the product has no halal logo and contains E640, contact the manufacturer to verify the source.
Is E640 suitable for a halal diet?
Only with verification. Choose products with recognised halal certification, or contact the manufacturer to confirm the source of E640 before consuming.
