Carrageenan
Carrageenan is a natural hydrocolloid extracted from red seaweed, widely used in food systems for its gelling, thickening, and stabilizing functions. It helps improve texture, suspend particles, and enhance mouthfeel in dairy, meat, beverages, and plant-based formulations while maintaining product consistency.

2-Medical uses
A 2006 in vitro study and a 2007 mouse study at the National Cancer Institute in the United States suggested that carrageenans might function as a topical microbicide. A 1987 in vitro study in Spain revealed a broad-spectrum antiviral activity of carrageenan.
