Cakes that you fondly crave for contain emulgents. Biscuits, bread, frozen desserts, sodas, coffee creamers, caramels, margarines as well as extruded snacks have emulsifiers. Emulsifiers in food are usually included in the preparation of beverages as well as other food items requiring longer shelf life.
Mayonnaise, vinegarette and homogenized milk are also rich in oil-in-water emulsions.
