ALGINATE

Alginate is an apparently safe derivative of kelp, it is used as a food additive to maintain the desired texture in dairy products, canned frosting, and other factory-made foods. Propylene glycol alginate, a chemically- modified algin, thickens acidic foods (soda pop, salad dressing) and stabilises the head in beer.
