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.

APPLICATIONS: 1-Food and other domestic uses Desserts, ice cream, cream, milkshakes, salad dressings, sweetened condensed milks, and sauces: gel to increase viscosity. Beer: clarifier to remove haze-causing proteins Toothpaste: stabilizer to prevent constituents from separating Fruit Gushers: ingredient in the encapsulated gel Fire-fighting foam: thickener to cause foam to become sticky Shampoo and cosmetic creams: thickener Biotechnology: gel to immobilize cells/enzymes Pharmaceuticals: used as an inactive excipient in pills/tablets Soy milk and other plant milks: used to thicken, in an attempt to emulate the consistency of whole milk Diet sodas: to enhance texture and suspend flavours Pet food, Personal lubricants, Vegetarian hot dogs 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.
