Alginate is a natural polysaccharide derived from the cell walls of brown seaweeds. It is commonly used in various industries, including food, pharmaceuticals, and biotechnology, due to its ability to form gels and thicken solutions. Alginate is often found in products like ice cream, salad dressings, and as a thickening agent in sauces. In addition to its culinary uses, alginate plays a significant role in medical applications. It is used in wound dressings and drug delivery systems because of its biocompatibility and ability to absorb moisture. Alginate's unique properties make it a valuable material in both food science and healthcare.
