GMS is largely used in baking preparations to add "body" to the food. It is somewhat responsible for giving ice cream and whipped cream their smooth texture. It is sometimes used as an antistaling agent in bread. It can also be used as an additive in plastic, where GMS works as an antistatic and antifogging agent.Glycerol monostearate, or GMS, is available in the baking aisles of most major grocery stores. A white, odorless, flaky powder, GMS is often found as an added ingredient in pre-packaged baking mixes, where it acts as an emulsifier, providing body and lift to a baked good's finished crumb.
