What it is
Red seaweed extract, also known as carrageenan, is a food additive derived from red seaweed. It is extracted from various species of red algae, primarily those in the Gigartinaceae and Solieriaceae families. The process involves washing, drying, and then extracting the carrageenan with hot water or alkali.
Why it's used
Carrageenan is commonly used as a thickener, stabilizer, and emulsifier in a variety of food products. Its ability to form gels and thicken liquids makes it useful in dairy products like ice cream and yogurt, as well as processed meats, sauces, and desserts. It helps improve texture and prevent ingredients from separating.
Health notes
In the U.S., carrageenan is generally recognized as safe (GRAS) by the FDA for use as a food additive. Some studies have raised questions about its potential effects on digestion, but regulatory bodies like the WHO/FAO Joint Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated it. Evidence regarding its impact on human health at typical consumption levels is mixed, and research is ongoing.
Allergen info
Carrageenan is derived from seaweed and is not one of the FDA's nine major food allergens. It does not contain gluten.
