The most frequently used raw materials for *emulsifiers include palm oil, rapeseed oil, soy bean oil, sunflower oil or lard/tallow. Egg* happens to be the oldest emulsifier. Basic emulsifier production involves combining oil (triglyceride) with glycerol that results in monoglyceride. The type of triglyceride used in the reaction determines the type of emulsifier obtained. Unsaturated triglycerides produce fluid products such as oil while saturated triglycerides result in pasty or solid structures like butter. Monoglycerides can be combined with other substances, such as citric acid and lactic acid, in order to increase their emulsifying properties. Emulsifiers are used in creams and sauces, bakery, and dairy products. They may be derived from the natural products or chemicals. Common emulsifiers are lecithins, mono- and di-glycerides of fatty acids esters of monoglycerides of fatty acids and phosphated monoglycerides.
