Mucilage is a thick, gel-like substance produced by various plants, algae, and microorganisms. It is primarily composed of polysaccharides, which are long chains of sugar molecules. Mucilage serves several functions, including water retention, seed germination, and protection against pathogens. It can be found in plants like okra and slippery elm. In addition to its role in the plant kingdom, mucilage has applications in food and industry. It is often used as a thickening agent in products like ice cream and salad dressings. Mucilage is also studied for its potential health benefits, including its ability to aid digestion and promote gut health.
