Typical source

Milk sugar (lactose)

Plain-language explanation

E966, or lactitol, is a sugar substitute derived from lactose, which is the natural sugar found in milk. It is produced by hydrogenating lactose, a process that does not introduce any non-halal substances, making it generally considered halal by major certification bodies like JAKIM, MUI, and MUIS. Its halal status is not typically a concern, as the source is milk and the manufacturing process is straightforward, but consumers should ensure the milk used is from halal-certified animals.
