Agar vs. Carrageenan: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on January 10, 2024
Agar is a gelatinous substance from seaweed used in food and labs; Carrageenan is a seaweed extract used as a thickener and stabilizer in food.

Key Differences

Agar is derived from red algae and is a mixture of two components: agarose and agaropectin. Carrageenan, also from red algae, contains various polysaccharides, which differ based on the type of carrageenan.

In the food industry, agar is used as a vegetarian gelatin substitute and thickener, known for its strong gelling properties. Carrageenan, on the other hand, is widely used as a thickener, stabilizer, and gelling agent, particularly in dairy and meat products.

Agar forms firm gels at low concentrations and doesn't melt easily, making it ideal for high-temperature cooking. Carrageenan forms softer gels and is often used to improve the texture of foods, but it does not gel as strongly as agar.

Agar is extensively used in microbiology for culture media due to its stability and non-reactivity with most chemicals. Carrageenan, while not typically used in lab settings, has applications in pharmaceuticals as a stabilizer in various formulations.
