1The Colloid Structure of Marshmallow Fluff
Marshmallow toppings are complex gas-in-liquid emulsions. Gelatin proteins lower surface tension, allowing air to be whipped into tiny bubbles that are suspended in a highly concentrated, viscous sucrose-and-glucose syrup.
- Protein Foam: Gelatin coats air bubbles, preventing coalescence.
- Syrup Viscosity: Concentrated sugars prevent water from draining out of the foam.
2Gelatin Sol-Gel Transition
As the pie cools, the stretched gelatin polypeptide chains form a three-dimensional triple-helix network. This locks the sugar-water molecules and air bubbles in a stable, rubbery gel.
- Sol-Gel Transition: Occurs rapidly as temperature drops below 35°C.
- Triple-Helix Bonding: Reversible hydrogen bonds give marshmallow its springiness.
3Baking Response and Thermal Expansion
When exposed to high heat under a broiler, the trapped air bubbles expand. Simultaneously, the sugar caramelizes, forming a thin, brown, crispy crust that locks in the molten interior.
- Thermal Expansion: Charles's Law dictates the expanding foam volume.
- Maillard Browning: Reducing sugars react with proteins to produce a caramelized skin.
