Emulsifying surfactant is a category

In the Chinese mainland called emulsifiers. Emulsifiers are a large class of surfactants , may stabilize the emulsion . The reason is , emulsifying two substances can be dispersed in water physiognomy , or double -layer thin film is formed , droplets of the dispersed phase with each other to prevent condensation , the formed emulsion is stable . For example, Lactic acid original drug ( solid ) or oil ( liquid ) in a certain amount of emulsifier , then they are dissolved in an organic solvent , the mixing can be made after a transparent liquid , called EC. The emulsifiers used are soaps , acacia , alkylbenzene sulfonate .
However, some emulsifiers can be used as food additives , primarily for immiscible oil ( hydrophobic material ) , and water ( hydrophilic substance) foods , so that the oil and water two- phase reduce the surface tension , the two surfaces to form a protective film , lactic acid powder the oils can be uniformly stable in water , so that stability of aqueous material in the oil evenly . So , beverages ( sports drinks, fruit juices and jellies ) , dairy products, pastries, pasta and so can add emulsifiers , so that food looks fluffy , soft, foam , food there is moist, the role of lubrication and durability , but also to food appearance looks homogeneous liquid solution , control solution crystallization , precipitation , thus changing the quality of the food , flavor and taste.
