Agar 750/800;800/850 – Natural thickener and gelling miracle in food and cosmetic industry

Agar with the 750/800 and 800/850 designations is a high-purity extract of red algae (mainly of the Gelidium and Gracilaria genera), commonly used as a natural gelling, stabilizing and thickening agent. It mainly contains polysaccharides – agarose and agaropectin – which give it unique structural properties. These products, with varying gelling strengths (750 to 850 g/cm²), are used both in laboratories and in the food and cosmetic industries.

Thanks to its plant-based origin and lack of calories, agar is very popular as an alternative to gelatin – especially in vegan applications. But its capabilities go much further. Meet Agar 750/800;800/850 – a natural, powerful ingredient with applications ranging from ice cream to laboratory lines.
