What the Data Says About

Carrageenan currently appears in 17,853 products across the OpenFoodFacts catalog we index, which gives a concrete measure of its footprint on US grocery shelves. Our internal safety score of 2/5 synthesizes FDA Substances Added to Food (SAFFA) regulatory status — currently "GRAS" — with the Center for Science in the Public Interest (CSPI) Chemical Cuisine classification of "Caution." These two frameworks capture different questions: regulators ask whether exposure at typical intake is acceptable, while consumer-advocacy groups examine cumulative dietary load and vulnerable-population risk.

In food manufacturing, Carrageenan functions as a anticaking agent or free-flow agent, drying agent, emulsifier or emulsifier salt, flavor enhancer, flavoring agent or adjuvant, formulation aid, humectant, processing aid, stabilizer or thickener, texturizer. That technical role explains why it recurs across many product categories — formulators select specific additives for stability, shelf life, color, or texture performance, and substitution is rarely a one-for-one swap when regulations or consumer preferences shift. Inspection and outbreak data often trace back to breakdown in the control of exactly these kinds of functional ingredients, either through contaminated batches, undisclosed substitutions, or labeling errors that trigger FDA-initiated recalls.

Documented concerns for Carrageenan include: controversial Consumers with diagnosed sensitivities, pregnant individuals, and parents of young children generally benefit from reviewing product-level detail pages to see the specific items in our catalog that contain this ingredient.
