A hydrocolloid is a substance that forms a gel-like consistency when mixed with water. It is made up of hydrophilic (water-attracting) molecules, which can absorb and retain moisture. Hydrocolloids are commonly used in food products, such as jellies, puddings, and sauces, to improve texture and stability. In addition to food applications, hydrocolloids are also utilized in the medical field. They are often found in wound dressings because they create a moist environment that promotes healing. Hydrocolloids can help protect wounds from infection while allowing for the absorption of exudate.
