Marshmallows are one of the earliest confections known to humankind. They are made from only a few ingredients, which fall into two main categories: sweeteners and emulsifying agents. Sweeteners include corn syrup, sugar, and dextrose. Proportionally, there is more corn syrup than sugar because it increases solubility (the ability to dissolve) and retards crystallization. Corn starch, modified food starch, water, gum, gelatin, and/or whipped egg whites are used in various combinations. The resulting combination gives the marshmallows their texture. They act as emulsifying agents by maintaining fat distribution and providing the aeration that makes marshmallows puffy. Gum, obtained from plants, also can act as an emulsifier in marshmallows, but it is also important as a gelling agent.
A solution is formed by dissolving sugar and corn syrup in water and boiling it. Egg whites and/or gelatin is mixed with the sugar solution. Then the ingredients are heated in a cook kettle to about 240�F (115�C). The resulting mixture is passed through a strainer to remove extraneous matter.
In the pump, the mixture is then beaten into a foam to two or three times its original volume. At this stage, flavoring can be added. The heated mixture is transferred to a heat exchanger. Air is pumped into the mixture. The mixture cools in a tempering kettle, passes through another filter, and continues on to the "hill." Marshmallows are extruded through a machine or deposited onto bands.
The extrusion process involves the foam being squeezed through a die to produce marshmallow's familiar pillow shape. Usually, they get a coating of corn starch to counter stickiness and help maintain their form after they have been extruded.
The pillows are formed into a rope of pillows and are cut and dried on a rubber conveyor belt.
The "guillotine" cuts the pillows to its appropriate length.
After the pillows have cooled, they are weighed and packaged.
A view of the whole production process. It's the marshmallow factory category after all! XD

My category f@#$%&* stinks!
