E558Anti-caking agentLow concern
Bentonite
In plain words
The short version
A natural smectite clay — the standard wine fining agent and a clarifier for fruit juices.
Why it's green
It's widely considered safe at the amounts used in food, so we mark it green. The Safety section below has the details.
Safety profile
ADI not specified — considered safe at typical use levels (residue in finished beverage is essentially zero). Bentonite is filtered out after the fining step. Naturally contains trace heavy metals, so food-grade material must meet purity criteria.
