Mannan is a type of polysaccharide, which is a long chain of sugar molecules. It is primarily derived from the cell walls of certain plants, particularly seaweeds and legumes. Mannan is known for its ability to form gels and thicken solutions, making it useful in various food and pharmaceutical applications. In addition to its culinary uses, mannan has potential health benefits. It can act as a prebiotic, promoting the growth of beneficial gut bacteria. This can contribute to improved digestive health and overall well-being, making mannan an interesting subject of study in nutrition and health sciences.
