Marshmallows have been a beloved treat for many, enjoyed in s’mores, hot chocolate, and as a snack on their own. However, one of the most notable characteristics of marshmallows is their tendency to become sticky. This phenomenon can be frustrating, especially when handling or storing them. But have you ever wondered why marshmallows get sticky in the first place? In this article, we will delve into the world of marshmallows and explore the science behind their stickiness.
Introduction to Marshmallows
Marshmallows are a type of confectionery made from sugar, corn syrup, and gelatin. They are known for their soft, fluffy, and lightweight texture. The process of making marshmallows involves whipping the mixture of sugar, corn syrup, and gelatin until it becomes light and airy. This whipping process incorporates air into the mixture, creating the characteristic texture of marshmallows.
The Role of Ingredients
The ingredients used to make marshmallows play a crucial role in their stickiness. Sugar and corn syrup are the primary contributors to the stickiness of marshmallows. These ingredients are hygroscopic, meaning they attract and retain moisture from the air. When marshmallows are exposed to air, the sugar and corn syrup absorb moisture, causing the marshmallows to become sticky.
Humidity and Temperature
Humidity and temperature are also important factors that contribute to the stickiness of marshmallows. High humidity and warm temperatures can cause marshmallows to become sticky and soft. When the air is humid, the sugar and corn syrup in the marshmallows absorb more moisture, leading to an increase in stickiness. Similarly, warm temperatures can cause the marshmallows to soften and become more prone to sticking.
The Science of Stickiness
The stickiness of marshmallows can be explained by the concept of viscoelasticity. Viscoelasticity refers to the ability of a material to exhibit both viscous and elastic properties. In the case of marshmallows, the sugar and corn syrup molecules are arranged in a way that creates a viscous and elastic network. When marshmallows are exposed to moisture, the network breaks down, causing the marshmallows to become sticky.
The Role of Gelatin
Gelatin is another important ingredient in marshmallows that plays a role in their stickiness. Gelatin helps to strengthen the network of sugar and corn syrup molecules, making the marshmallows more resistant to moisture. However, when gelatin is exposed to heat or moisture, it can break down, causing the marshmallows to become sticky.
Moisture Content
The moisture content of marshmallows is also a critical factor in their stickiness. Marshmallows with high moisture content are more prone to stickiness. When marshmallows are exposed to air, they can absorb moisture, leading to an increase in moisture content. This increase in moisture content can cause the marshmallows to become sticky and soft.
Practical Applications and Solutions
Understanding the reasons behind the stickiness of marshmallows can help us find practical solutions to this problem. One way to prevent marshmallows from becoming sticky is to store them in an airtight container. This helps to prevent the marshmallows from absorbing moisture from the air. Another solution is to add a drying agent, such as cornstarch or powdered sugar, to the marshmallows. This helps to absorb any excess moisture and prevent the marshmallows from becoming sticky.
Industrial Applications
The stickiness of marshmallows can also have implications for industrial applications. Food manufacturers can use this knowledge to develop packaging and storage solutions that prevent marshmallows from becoming sticky. For example, using moisture-resistant packaging or adding drying agents to the packaging can help to prevent marshmallows from absorbing moisture and becoming sticky.
Conclusion
In conclusion, the stickiness of marshmallows is a complex phenomenon that involves the interplay of various factors, including ingredients, humidity, temperature, and moisture content. By understanding the science behind the stickiness of marshmallows, we can develop practical solutions to prevent this problem. Whether you are a food manufacturer or a consumer, knowing why marshmallows get sticky can help you to appreciate these tasty treats even more.

By understanding and addressing the factors that contribute to marshmallow stickiness, we can enjoy these treats while minimizing the hassle of their sticky nature.
What causes marshmallows to become sticky?
Marshmallows become sticky due to their high moisture content and the structure of their ingredients. When marshmallows are exposed to air, the moisture on their surface evaporates, causing the marshmallow to dry out slightly. However, if the air is humid or the marshmallow is not dried properly, the moisture can become trapped, leading to a sticky surface. The main culprit behind the stickiness is the gelatin in marshmallows, which is a protein that absorbs and retains moisture.
The gelatin in marshmallows is typically derived from animal products, such as bones and connective tissue. When gelatin is mixed with sugar, water, and other ingredients, it forms a network of protein chains that give marshmallows their characteristic texture. However, this network can also absorb and retain moisture, leading to stickiness. Additionally, the sugar in marshmallows can contribute to stickiness by absorbing moisture from the air and creating a sticky film on the surface of the marshmallow. By understanding the role of gelatin and sugar in marshmallows, we can better appreciate why they tend to become sticky under certain conditions.
How does humidity affect the stickiness of marshmallows?
Humidity plays a significant role in determining the stickiness of marshmallows. When the air is humid, the moisture in the air can be absorbed by the marshmallow, causing it to become sticky. This is because the gelatin in marshmallows is highly sensitive to moisture, and high humidity can cause it to absorb more moisture than it would in a dry environment. As a result, marshmallows are more likely to become sticky in humid environments, such as near oceans or in tropical climates.
In contrast, dry environments can help to reduce the stickiness of marshmallows. When the air is dry, the moisture on the surface of the marshmallow can evaporate more quickly, reducing the stickiness. This is why marshmallows are often packaged in airtight containers or bags to maintain a dry environment and prevent moisture from entering. By controlling the humidity level, manufacturers can help to minimize the stickiness of marshmallows and keep them fresh for longer.
Can the type of sugar used in marshmallows affect their stickiness?
The type of sugar used in marshmallows can indeed affect their stickiness. Different types of sugar have varying levels of hygroscopy, which is the ability to absorb moisture from the air. For example, granulated sugar is more hygroscopic than corn syrup, which means it can absorb more moisture and contribute to stickiness. On the other hand, some sugars like honey and maple syrup are less hygroscopic and may produce less sticky marshmallows.
The choice of sugar can also affect the texture and structure of the marshmallow, which can in turn influence its stickiness. For instance, using a combination of granulated sugar and corn syrup can create a marshmallow with a smoother, more even texture that is less prone to stickiness. Additionally, some manufacturers may use specialized sugars or sugar substitutes that are designed to minimize stickiness and improve the overall texture of the marshmallow. By selecting the right type of sugar, manufacturers can help to reduce the stickiness of their marshmallows and create a more desirable product.
Do all types of marshmallows become sticky?
Not all types of marshmallows become sticky, although many do. The likelihood of a marshmallow becoming sticky depends on its ingredients, texture, and manufacturing process. For example, marshmallows made with egg whites or aquafaba (the liquid from canned chickpeas) tend to be less sticky than those made with gelatin. This is because egg whites and aquafaba contain proteins that are less prone to absorbing moisture than gelatin.
Some types of marshmallows, such as those made with agar agar or carrageenan, may also be less sticky due to their unique ingredient profiles. Agar agar, for instance, is a vegan alternative to gelatin that is derived from red algae and has a lower moisture-absorbing capacity. Similarly, carrageenan is a seaweed-based ingredient that can help to reduce stickiness in marshmallows. By using alternative ingredients and manufacturing processes, manufacturers can create marshmallows that are less prone to stickiness and have improved texture and shelf life.
How can I prevent marshmallows from becoming sticky?
To prevent marshmallows from becoming sticky, it’s essential to store them in a dry, airtight environment. This can be achieved by placing the marshmallows in a sealed container or plastic bag and keeping them away from direct sunlight and moisture. Additionally, using a desiccant or silica gel packet can help to absorb any excess moisture in the container and keep the marshmallows dry.
Another way to prevent stickiness is to use a light coating of powdered sugar or cornstarch on the surface of the marshmallows. This can help to absorb any excess moisture and reduce the stickiness. Some manufacturers also use specialized coatings or glazes to minimize stickiness and improve the texture of their marshmallows. By taking these precautions, you can help to keep your marshmallows fresh and prevent them from becoming sticky.
Can I still use sticky marshmallows for cooking and baking?
Yes, you can still use sticky marshmallows for cooking and baking, although they may require some additional handling. Sticky marshmallows can be used in recipes where they will be melted or dissolved, such as in hot chocolate or marshmallow fluff. In these cases, the stickiness is not a major issue, as the marshmallows will be fully incorporated into the mixture.
However, if you’re using sticky marshmallows in a recipe where they need to be toasted or browned, such as in s’mores or rice Krispy treats, you may need to take some extra steps. For example, you can try dusting the marshmallows with powdered sugar or cornstarch to reduce stickiness, or using a lower heat setting to prevent them from melting or becoming too sticky. With a little creativity and experimentation, you can still use sticky marshmallows to create delicious treats and desserts.
