Emulsifiers are substances that help stabilize mixtures of oil and water by reducing the surface tension at the interface of the two phases. Carrageenan serves this purpose effectively due to its ability to interact with both hydrophilic (water-attracting) and hydrophobic (water-repelling) molecules. When added to emulsions, carrageenan enhances the physical stability of oil-in-water or water-in-oil systems by forming a protective layer around dispersed droplets, preventing coalescence and separation. This functionality is particularly crucial in food products where texture and consistency are key to consumer acceptance.
One of the most remarkable properties of xanthan gum is its ability to remain stable across a broad range of temperatures and pH levels. This stability allows food products to maintain their consistency from production to consumption. Additionally, xanthan gum has exceptional thickening capabilities; even in small amounts, it can significantly increase the viscosity of a liquid.
