Check a product, not just a number
An additive's status describes the additive in general. What matters is the whole ingredient list on the packet in your hand.
This is information, not a fatwa. These statuses combine published scholarly positions with ingredient analysis, and they can be incomplete or out of date. For anything that matters, confirm with the manufacturer and with a qualified authority.
