Carrageenan – it sounds exotic, but for many people, it’s already a part of everyday life. In yogurt, ice cream, or toothpaste, carrageenan helps ensure the right consistency and stability. The plant-based gelling and thickening agent is commonly used in foods as additive E 407 and is approved without quantity restrictions. The substance comes from red algae and consists of long sugar chains with many so-called sulfate groups. These very sulfations make carrageenan both intriguing and complex.
Signposts for crisis-proof food systems
The way in which fields are cultivated and food is produced has a lasting impact on the environment and climate. Around a third of global greenhouse gas emissions, biodiversity loss and soil degradation are caused by global agricultural and food systems. The Leibniz research network ‘Green Food - Healthy Society’ is now providing a new systemic approach to tackling these challenges.
