Galactan is a polysaccharide primarily used in food and pharmaceutical industries due to its gelling and thickening properties. It serves as a dietary fiber supplement, supporting digestive health by promoting beneficial gut bacteria. In food products, it acts as a stabilizer in dairy items and plant-based alternatives, improving texture and shelf life. Galactan is also explored in drug delivery systems for its biocompatibility and ability to form hydrogels, enabling controlled release of active compounds. Additionally, it finds use in cosmetic formulations as a natural moisturizer and skin-conditioning agent.
