Marshmallows are not typically made directly from bones. However, they do contain an ingredient called gelatin, which is derived from animal bones and other parts. Gelatin is a protein that is extracted from the skin, ligaments, tendons, and bones of cows or pigs through a process called hydrolysis.
To make gelatin, the animal parts are first cleaned and then boiled to extract the collagen protein. Collagen is the main structural protein found in connective tissues, and it gives gelatin its thickening and gelling properties. Once the collagen is extracted, it is further processed and purified to remove any impurities.
The purified collagen is then mixed with water and heated to create a gelatin mixture. This mixture is used as a binding and stabilizing agent in various food products, including marshmallows. In the case of marshmallows, the gelatin helps give them their fluffy and spongy texture.
When making marshmallows, the gelatin is combined with sugar, corn syrup, and water. This mixture is then heated and whipped to incorporate air, creating a light and fluffy marshmallow mixture. The mixture is then poured into molds or shaped into individual marshmallows and left to set.
It’s important to note that not all marshmallows are made with gelatin derived from animal sources. There are also vegetarian and vegan alternatives available, which use plant-based ingredients like agar-agar or carrageenan to achieve a similar texture.
While marshmallows themselves are not made directly from bones, they do contain gelatin, which is derived from the skin, ligaments, tendons, and bones of animals. Gelatin serves as a thickening and binding agent in marshmallows, giving them their characteristic texture.
