What is Gelatin and Why is it in Sweets?
Gelatin is a protein derived from animal collagen that functions as a gelling, binding, whipping, and stabilizing agent in many food products. Its unique properties allow it to form elastic films that trap air and liquids, which is why it is so crucial for creating the textures of countless confections. For sweets, gelatin is prized for its ability to produce a wide range of consistencies, from the firm chewiness of gummy candies to the light fluffiness of marshmallows. Its concentration, measured by 'Bloom' strength, is carefully controlled by manufacturers to achieve the desired result in the final product.
The Top Contenders: Sweets with High Gelatin Content
Gummy Candies
When considering which sweets have the most gelatin, gummies are the clear frontrunner. Their firm, elastic, and chewy texture is the result of a significant concentration of gelatin. Different formulations and manufacturing processes will influence the exact amount, but gummy foams can contain up to 7% gelatin to achieve the desired chewiness. Other studies on gummies mention a 4–6% gelatin concentration as standard for confectionery gels. The gelatin allows these sweets to hold their fun and intricate shapes while providing the satisfying chew consumers expect. Some popular brands known for their high gelatin gummies include Haribo and Trolli.
Marshmallows
Marshmallows are another prominent confection that relies heavily on gelatin, although in a different way than gummies. Gelatin in marshmallows works primarily to create a stable foam, trapping air bubbles to create the light, airy texture. The concentration is typically lower than in gummies, with producers using around 2.5% of a specific gelatin type to achieve the fluffy consistency. This aerated quality is what prevents the marshmallow from being dense or hard. Without gelatin, marshmallows would not have the soft, melt-in-your-mouth feel that makes them so popular.
Gelatin Desserts (Jello)
These products, sold as flavored powders, are essentially pure gelatin and sugar. When prepared, they contain a concentration of gelatin typically ranging from 1.5% to 2.5%. The concentration can vary depending on the desired firmness, with higher bloom strength gelatins allowing for a firmer set at lower concentrations. While these desserts are entirely defined by gelatin, the final, diluted product actually has a lower overall concentration than many types of gummies.
Nougat and Chewy Candies
Gelatin's use extends beyond just gummies and marshmallows to include chewy candies and aerated nougats found in popular chocolate bars. In these cases, it acts as a whipping agent to provide aeration and adds to the candy's unique texture. While a key component, the concentration of gelatin in these products is typically lower compared to gummies, as other ingredients like egg whites and sugars also contribute to the final chewiness.
Understanding the Difference: Gummy vs. Marshmallow
The difference in gelatin concentration between gummies and marshmallows is a perfect example of how this ingredient's properties are manipulated. Gummy candies are designed to be dense and very chewy, requiring a higher percentage of gelatin to create a firm gel network. Marshmallows, in contrast, need only enough gelatin to stabilize a large volume of trapped air, resulting in a lighter, less concentrated final product. This results in a sweet that feels substantially different, even though both rely on the same fundamental ingredient.

Comparison Table: Gelatin Use in Sweets
| Sweet Type | Typical Gelatin Concentration (approximate) | Primary Function of Gelatin |
|---|---|---|
| Gummy Candies | 4-7% | Provides elastic, firm, and very chewy texture. |
| Marshmallows | 1-2.5% | Stabilizes foam, creates light and airy texture. |
| Gelatin Desserts (Jello) | 1.5-2.5% | Forms a gel, giving the dessert its shape and texture. |
| Nougat | Variable, typically lower than gummies | Acts as a whipping agent to aerate and add chewiness. |
| Jelly Beans (some) | Variable, can be low or none | Contributes to the chewy inner consistency for brands that use it. |
Label Reading and Alternatives
Because gelatin is an animal product, it is essential for those with dietary restrictions (e.g., vegetarians, vegans) to read ingredient labels carefully. Many manufacturers now offer vegan alternatives using plant-based thickeners such as agar-agar, pectin, or carrageenan to create a similar texture. Specific brands like Jelly Belly do not use gelatin in their jelly beans, but other types of jelly beans may. Chewing gum brands like Wrigley's and Mentos have varieties both with and without gelatin, so checking the specific product is vital.
Conclusion
While many sweets rely on gelatin for their structure, gummy candies contain the highest concentration. Their chewy, resilient texture is a direct result of a formulation that can include up to 7% gelatin, significantly more than the airy foam of marshmallows or the soft gel of prepared desserts. Understanding the amount and function of gelatin in different sweets provides valuable insight for those with dietary restrictions and for anyone curious about the science behind their favorite candy. Always check the ingredients list on the packaging to be certain of a product's gelatin content, especially with the prevalence of both traditional and plant-based options available today.
