The Shared Foundation: Gelatin, Sugar, and Corn Syrup
At their heart, the basic formulas for both marshmallows and gummy bears are remarkably similar, relying on a common set of foundational components. The primary structural ingredient is gelatin, a gelling agent derived from animal collagen. Gelatin's ability to form a thermally reversible gel is crucial to the signature texture of both candies, providing the stretch in marshmallows and the chewiness in gummies.
Beyond gelatin, the dominant sweeteners in both confections are sugar and corn syrup. Sugar, primarily sucrose, provides the bulk of the sweetness and bulk. Corn syrup, however, is a critical addition that prevents sugar from crystallizing into a grainy texture, ensuring a smooth mouthfeel. The combination of these two sweeteners allows candymakers to control the candy's texture and moisture.
Gelatin: The Key to Structure
Gelatin plays a different, but equally vital, role in each candy. In gummy bears, a higher concentration of gelatin is used to form a strong, self-supporting gel network. This tight molecular structure is what gives gummies their firm, resilient, and chewy characteristics. The hot, liquid mixture is poured into molds and cooled, allowing the gelatin to set firmly. For marshmallows, a much lower concentration of gelatin is used. Here, the gelatin's main purpose is to stabilize the large amount of air that is whipped into the mixture, creating a light, spongy, and pliable foam. The gelatin creates a delicate network that traps air bubbles, resulting in the marshmallow's iconic fluffy texture.
Sweeteners and Other Ingredients
While sugar and corn syrup form the base, the specific types and ratios can vary. For example, some candies may use dextrose or other types of sugar. Flavourings, colors, and acids like citric acid are also added to customize the taste and appearance of both candies. Citric acid, in particular, is a common addition to gummy bears to provide the signature sour tang that complements the sweet fruit flavors. Marshmallows, on the other hand, often incorporate vanilla extract and a dusting of cornstarch and powdered sugar to prevent sticking.
The Impact of Processing
The most significant difference between the two treats lies in their manufacturing process. For marshmallows, the gelatin-sugar mixture is intensely whipped to incorporate a large volume of air, transforming it into a stable foam. This process results in a low-density, airy product. Gummy bears, by contrast, are not aerated. The gelatin-sugar mixture is poured into starch molds and left to cool, resulting in a dense, solid gel. This fundamental difference in processing is the sole reason for their dramatically different textures, despite their similar ingredients.
The Rise of Vegan Alternatives
Given that gelatin is an animal-derived product, it is unsuitable for vegetarians and vegans. This has led to the development of numerous plant-based alternatives that have reshaped the confectionery landscape. Gelling agents such as pectin (derived from fruits) and agar-agar (from algae) are popular substitutes. However, the texture created by these alternatives is not identical to that of gelatin. Agar-agar, for example, typically produces a firmer, more brittle gel, while pectin results in a softer set. Some brands may even use starch-based formulas. This makes reading ingredient labels crucial for those with dietary restrictions or preferences, as a candy that looks like a gummy bear or marshmallow might use a different base entirely.
Marshmallow vs. Gummy Bear: A Nutritional and Textural Comparison
To highlight the nuances between these two classic treats, consider the following comparison table:
| Feature | Marshmallows | Gummy Bears |
|---|---|---|
| Key Ingredients | Gelatin, corn syrup, sugar, water, air | Gelatin, corn syrup, sugar, water, starch, citric acid, flavorings |
| Texture | Soft, spongy, light, airy foam | Firm, chewy, resilient, dense gel |
| Processing Difference | Whipped vigorously to incorporate air | Poured into molds and set without aeration |
| Sweeteners | Sugar, corn syrup, often dusted with powdered sugar | Sugar, corn syrup, and various additives |
| Vegan Alternatives | Uses plant-based gelling agents like agar-agar to create a non-aerated marshmallow creme | Uses plant-based gelling agents like pectin or agar-agar, which alter the chewiness |
| Overall Density | Very low density due to high air content | High density, solid gel structure |
Conclusion
So, do marshmallows and gummy bears have the same ingredients? The answer is both yes and no. They share a core foundation of gelatin, sugar, and corn syrup, but the specific ingredient ratios and, most importantly, the manufacturing process create two fundamentally different products. The whipped air in a marshmallow is what sets it apart from the dense gel of a gummy bear. Understanding these differences not only provides a lesson in food science but also highlights why, despite a shared ancestry, these candies offer such distinct sensory experiences.

The Bigger Picture: Nutrition and Your Diet
From a nutritional diet perspective, both marshmallows and gummy bears are high-sugar confections and should be consumed in moderation. They offer minimal nutritional value beyond carbohydrates and calories. For those with dietary concerns, the rise of vegan options offers alternatives to the traditional gelatin-based formulas. Reading ingredient lists carefully will always be the most reliable way to understand exactly what you are consuming.
The Science of Textural Differences
The differences in texture are a direct result of the application of food science principles. The amount of gelatin used dictates the firmness of the gel, while the process of whipping air into the sugar solution creates a foam. This precise control over ingredients and processing is the hallmark of confectionery manufacturing, transforming a handful of shared components into a diverse array of delightful treats.
