In the late 19th century, French manufacturers thought of using egg whites or gelatin , combined with modified corn starch , to create the chewy base.
This avoided the labour-intensive extraction process, but it did require industrial methods to combine the gelatin and corn starch in the right way.
Another milestone in the production of marshmallows was the development of the extrusion process by the Greek American confectioner Alex Doumak, of Doumak Inc.
In this process, which Doumak patented in ,  marshmallow mixture is pumped through extrusion heads with numerous ports aligned next to each other which form continuous "ropes" of marshmallow.
This invention allowed marshmallows to be manufactured in a fully automated way and gives us the familiar cylindrical shape of today's marshmallow.
To make marshmallows in large quantities, industrial confectioners mix water, sugar, and corn syrup in massive kettles which are then heated to a precise temperature and cooked for a precise time.
This mixture is then pumped to another kettle to cool. Re-hydrated gelatin is added and blended in, once the mixture has cooled enough to not denature the gelatin.
To give the marshmallow its fluffiness, it is pumped through a blender while air is pumped into it. At this point, it still needs to be cooled further, so it will hold its shape when extruded, it is pumped through a heat exchanger prior to being pumped through the extrusion heads and onto a wide conveyor belt.
The conveyor belt is coated in corn starch and more corn starch is dusted onto the top of the marshmallow extrusion as it passes down the conveyor.
A large knife the width of the conveyor is located at the end of this conveyor table that chops the extrusion into the size marshmallow desired.
The pieces will then be tumbled in corn starch in a large drum, allowing the marshmallow to form its familiar skin and to allow pieces that did not get cut all the way to break apart.
Marshmallows, like most candies, are sweetened with sucrose. They are prepared by the aeration of mixtures of sucrose and proteins to a final density of about 0.
The molecular structure of marshmallows is simply a sugar solution blended with stabilizing structure agents such as gelatin , xanthan gum , or egg whites.
The aforementioned structural components prevent the air from escaping and collapsing the marshmallows during aeration. Each brand of marshmallow has its own specific formula for how to produce the 'perfect' marshmallow.
No matter how they are made each ingredient plays a specific role in the final product. The marshmallow is a foam , consisting of an aqueous continuous phase and a gaseous dispersed phase in other words, a liquid with gas bubbles spread throughout.
The goal of an aerated confection like marshmallow is to incorporate gas into a sugar mixture, and stabilize the aerated product before the gas can escape.
When the gas is introduced into the system, tiny air bubbles are created. This is what contributes to the unique textural properties and mouth-feel of this product.
In marshmallows, proteins are the main surface-active agents responsible for the formation, and stabilization of the dispersed air.
Due to their structure, surface-active molecules gather at the surface area of a portion of water-based liquid. A portion of each protein molecule is hydrophilic , with a polar charge, and another portion is hydrophobic and non-polar.
The non-polar section has little or no affinity for water, and so this section orients as far away from the water as possible.
However, the polar section is attracted to the water and has little or no affinity for the air. Therefore, the molecule orients with the polar section in the water, with the non-polar section in the air.
Two primary proteins that are commonly used as aerators in marshmallows are albumen egg whites and gelatin. Albumen is a mixture of proteins found in egg whites, and is utilized for its capacity to create foams.
In a commercialized setting, dried albumen is used as opposed to fresh egg whites. In addition to convenience, the advantages of using dried albumen are an increase in food safety, and the reduction of water content in the marshmallow.
Fresh egg whites carry a higher risk of Salmonella, and are approximately 90 percent water. This is undesirable for the shelf life and firmness of the product.
For artisan-type marshmallows, prepared by a candy maker, fresh egg whites are usually used. Albumen is rarely used on its own when incorporated into modern marshmallows, and instead is used in conjunction with gelatin.
Gelatin is the aerator most often used in the production of marshmallows. It is made up of collagen, a structural protein derived from animal skin, connective tissue, and bones.
Not only can it stabilize foams, like albumen, but when combined with water it forms a thermally-reversible gel. This means that gelatin can melt , then reset due to its sensitivity to temperature.
This is what contributes to the "melt-in-your-mouth" sensation when a marshmallow is consumed—it actually starts to melt when it touches the tongue.
During preparation, the temperature needs to be just above the melting point of the gelatin, so that as soon as it is formed it cools quickly, and the gelatin will set, retaining the desired shape.
If the marshmallow rope mixture exiting the extruder during processing is too warm, the marshmallow starts to flow before the gelatin sets.
Instead of a round marshmallow, it will take a more oval form. Excessive heat can also degrade, or break down, the gelatin itself. Therefore, when marshmallows are being produced at home or by artisan candy makers, the gelatin is added after the syrup has been heated and cooled down.
In commercial operations, the gelatin is simply cooked with the sugar syrup, rather than being added later after the syrup has cooled. In this case, kinetics play an important role, with both time and temperature factoring in.
The marshmallow would have reduced springiness from that loss of gelatin. But since the time the syrup spends at elevated temperature in modern cookers is so short, there is little to no degradation of the gelatin.
In terms of texture, and mouth-feel, gelatin makes marshmallows chewy by forming a tangled 3-D network of polymer chains. Once gelatin is dissolved in warm water dubbed the "blooming stage" , it forms a dispersion, which results in a cross-linking of its helix-shaped chains.
The linkages in the gelatin protein network, trap air in the marshmallow mixture, and immobilize the water molecules in the network.
The result is the well-known spongy structure of marshmallows. Marshmallows are an amorphous solid because of how the sugars crystallize.
This is because the crystals formed are not grained, and very fine in size, as opposed to its crystalline counterpart where the crystals are grainy, and larger in size.
This is why temperature plays such an important role in the production of marshmallows. To make an amorphous solid like marshmallow, the sugar syrup solution sucrose, corn syrup, and invert sugar is heated at a high temperature.
It is then cooled so rapidly that no crystals have time to form. Marshmallow Challenge 0 PDF. Team-Building 20 - 30 min Small 8 Passive.
Save to Playlist. Environment Indoor. Distribute one kit to each small group. Instruct the groups to use only the contents of the kits to build the tallest free-standing structure, and to place the marshmallow on top highest peak of structure.
Explain that every group has exactly 20 minutes to complete the task. Take a look at the many Leadership Tips for some useful operational hints.
Remind your groups that the entire marshmallow must be on top — there is a tendency for some groups to want to break it up into smaller pieces, but this is not cool.
Limited Resources : Vary any one or more of the items in the kit, such as more or less spaghetti sticks, tape or string. Yet, as in the original challenge, a marshmallow must be positioned on top of the structure.
What exactly? What lessons does this challenge present to us? In many cases, three key lessons may bubble up from a debrief of this exercise: Children do better than adults, especially business and management graduates — on almost every measure of creativity, kindergarteners create taller and more interesting structures.
They are not bound by rules, engineering degrees and assumptions. Prototyping matters — the reason children do better than adults, and commerce graduates, in particular, is that young people spend more time playing and prototyping.
They naturally start with the marshmallow and poke in the sticks. The marshmallow is a metaphor for the hidden assumptions of a project: Most people assume that marshmallows are light and fluffy and easily supported by the spaghetti sticks.
Yet, when a group starts to build their structure, they discover that marshmallows are a lot heavier than they appear. This is the process which leads to effective innovation.
