Processed Eucheuma Seaweed
In plain words
The short version
PES — the cheaper, less-refined carrageenan, still containing seaweed cell-wall material.
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 (combined with E407, EFSA 2018 re-evaluation). Some studies suggest carrageenan-class molecules may have inflammatory effects on gut tissue, particularly at the cellular level; the human dietary relevance remains debated. The same considerations apply to PES.
