Matches personal ingredient preferences based on label evidence; not medical, allergy, or dietary safety advice

What the label is naming

Carrageenan is a thickener extracted from red seaweed. Labels use the common name or E407. It is filed with gums and emulsifiers because that is where preference lists put it. The explanation does not turn the seaweed source into a safety claim in either direction.

Where it hides

Chocolate milk, creamers, deli meat, yogurt, and ice cream. In dairy it is often near the end, next to guar or locust bean gum.

Questions

Is carrageenan matched because it comes from seaweed?

It is matched because the household avoids this ingredient and the label prints it. The seaweed origin is context, not a verdict.

Does E407a count?

The pattern covers E407. A trailing letter still sits against a word boundary in a way that may not match processed eucheuma seaweed (E407a). That distinct code is not silently folded in.
