What is Agar in Food industry?

Agar is a natural hydrocolloid obtained from red algae, primarily Gelidium and Gracilaria species, widely used in the food industry as a gelling agent, stabilizer, thickener, and texturizer. It forms a firm, thermo-reversible gel that sets at room temperature and remains stable under moderate heat, making it a valuable alternative to gelatin. Rich in polysaccharides, it’s contributes no flavor, odor, or calories, and is suitable for vegetarian and vegan applications. Other close terms include agar-agar, seaweed gelatin, vegetable gelatin, marine gum, and algal hydrocolloid. Known for its strong gel strength, clarity, and stability, this raw material is used in confectionery, bakery, dairy, beverages, and functional foods.
