What is Carrageenan?
E407 is the E-number for carrageenan, one of the thickeners & gelling agents group of food additives (E400–E499). Additives in this group thicken foods and create gels for the right texture. Extracted from red seaweed. Carrageenan is extracted from red seaweed and has been used in cooking (as Irish moss) for centuries. Degraded carrageenan (poligeenan) is harmful, but food-grade carrageenan is approved by EFSA — the distinction fuels much of the online debate. Like every E-number, E407 has been evaluated and authorised for use in food in the European Union — the 'E' literally stands for Europe, and a number is only granted after a safety assessment. That authorisation doesn't mean every additive suits every diet or that all concerns are settled, which is why we break down the safety, vegan, vegetarian and halal status of E407 in detail below.
