Carrageenan is used in dairy meat and beverage products as a stabilizer and gelling agent.
Food-grade carrageenan is a natural food additive derived from red seaweed, widely used as a thickening, gelling, and stabilizing agent in various food products. It is available in different types (kappa, iota, and lambda) and can be purchased from several online retailers in South Africa.
Characteristics and Uses
Carrageenan is a versatile, plant-based alternative to gelatin, and its specific properties vary by type.
Kappa Carrageenan: Forms strong, brittle gels, especially in the presence of potassium ions, and is ideal for dairy products (like chocolate milk, puddings, yogurts), meat products (ham, sausages), and vegan alternatives. It requires heat to dissolve and gels upon cooling.
Iota Carrageenan: Forms soft, elastic gels in the presence of calcium ions, making it suitable for items like frozen desserts, pie fillings, and soft gel capsules. It also aids in freeze-thaw stability.
Lambda Carrageenan: Primarily used as a thickener rather than a gelling agent, as it is cold soluble and does not form gels. It is often found in salad dressings, sauces, and some beverages where it enhances viscosity and mouthfeel.
Carrageenan is approved as “generally recognized as safe” (GRAS) by the FDA and the Joint FAO/WHO Expert Committee on Food Additives (JECFA), although some controversy exists among certain researchers regarding its potential health effects.
