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.
Traditional wheat varieties are resistant to fungi
Yellow rust, also known as stripe rust, is caused by the fungus Puccinia striiformis f. sp. tritici and is one of the most dangerous diseases in wheat cultivation. Around 88% of global bread wheat production is potentially affected by the pathogen. An international research team led by the University of Zurich (UZH) has now identified two genome segments in Asian wheat varieties that give the plants natural resistance to the disease.
