Gummy bears are made from a short list of ingredients: gelatin, sugar, glucose syrup, starch, citric acid, flavorings, and food coloring. That simplicity is deceptive, though, because each ingredient plays a specific role in creating the chewy, bouncy texture and bright fruity taste that makes gummy bears distinct from other candies. Here’s what actually goes into them and why.
Gelatin: The Key Ingredient
Gelatin is the backbone of a gummy bear. It’s a protein derived from animal byproducts, primarily cattle bones, pork skins, and cattle hides. The collagen in those connective tissues gets broken down into individual protein strands, which are then dried and ground into the powder that candy makers use. Higher quality gummy bears list gelatin as the first ingredient.
What makes gelatin special for candy is how it behaves when heated and cooled. When dissolved in warm water and mixed with the other ingredients, the protein strands float freely in the liquid. As the mixture cools, those strands reach out and try to reform their original structure, wrapping around sugar, water, flavor, and dye molecules in the process. The result is a tangled three-dimensional web that holds everything firmly in place. In some spots, the strands lock together in tight triple-helix junctions that give the candy its signature bounce and stretch.
The reason gummy bears seem to melt on your tongue is that these protein structures start unraveling at body temperature. That’s why a gummy bear feels firm when you first bite it but quickly turns slippery and almost liquid in your mouth. No other gelling agent replicates this exact sensation, which is why gelatin-based gummies have a noticeably different chew than plant-based alternatives.
Sugar and Glucose Syrup
The two main sweeteners in gummy bears are regular granulated sugar (sucrose) and glucose syrup, and they each do more than just add sweetness. In a conventional gummy candy formulation, glucose syrup makes up roughly 54% of the recipe. Sugar does the rest of the sweetening while also acting as a bulking agent that gives the candy its density and body.
Sugar improves the solubility of the other ingredients, prevents crystallization, and lowers the water activity inside the candy. That last point matters because lower water activity means bacteria and mold have a harder time growing, which is why gummy bears can sit in a bag on a shelf for months without spoiling. Glucose syrup reinforces these same effects, further preventing sugar crystals from forming and keeping the texture smooth rather than gritty. Together, the two sweeteners create the glossy, pliable consistency you expect from a gummy bear. A standard 40-gram serving (roughly a small handful) contains about 21 grams of sugar and 31 grams of total carbohydrates, with just 2 grams of protein from the gelatin.
Acids for Tartness and Balance
Without acid, gummy bears would taste flat and overly sweet. Citric acid is the most common addition, sourced naturally from citrus fruits. It sharpens the fruity flavors and adds the subtle tang you notice underneath the sweetness. Some manufacturers also use malic acid (from apples) for a more rounded sour note, or tartaric acid (from grapes) to fine-tune the flavor profile.
Sour gummy bears take this further with fumaric acid, which delivers a much stronger, longer-lasting sourness. Fumaric acid also stays stable at higher temperatures, making it practical for candy production. In small amounts, these acids double as preservatives, helping control the pH of the candy and keeping it shelf-stable.
Flavorings, Colors, and Coatings
The flavors in most commercial gummy bears are a mix of natural and artificial compounds designed to mimic fruits like raspberry, orange, lemon, strawberry, and pineapple. Food colorings, whether synthetic dyes or plant-based alternatives, match each flavor to the color you’d expect. The specifics vary by brand and market, with European formulations more likely to use natural colorings than their American counterparts.
You may have noticed that gummy bears have a slight sheen and don’t clump together in the bag. That comes from a thin coating, typically carnauba wax (from palm leaves) or beeswax. These hydrophobic waxes repel moisture and prevent the sticky candy surfaces from fusing together during storage. Some brands use a confectionery glaze or a light vegetable oil instead.
How They’re Shaped
Gummy bears get their shape through a process called starch molding. Trays filled with fine cornstarch are stamped with rows of tiny bear-shaped impressions. The warm, liquid gummy mixture is deposited into these molds and left to cool and set. The starch absorbs excess moisture from the surface, helping the gummies firm up and develop their final texture. Once set, the bears are flipped out of the trays, and the surrounding starch is removed with air suction and blowing nozzles. The starch is recycled and used again for the next batch, making it a shaping tool rather than an ingredient in the finished candy.
What Vegan Gummy Bears Use Instead
Because gelatin comes from animal tissue, it’s off the table for vegans, vegetarians, and people who follow halal or kosher diets (depending on the animal source). Several plant-based alternatives exist, though none perfectly replicate gelatin’s texture.
- Pectin is a powder extracted from citrus fruit skins. Pectin-based gummies are softer and more jelly-like, closer to a gumdrop than a traditional gummy bear.
- Agar-agar comes from seaweed. It produces a firmer candy than gelatin, with a higher melting point (185 to 203°F), so agar gummies don’t melt in your mouth the same way.
- Carrageenan, also from seaweed, creates a softer texture than either gelatin or agar, with a melting point between 122 and 158°F.
Most vegan gummy brands use pectin because its softer chew comes closest to what people expect, though the mouthfeel is noticeably different. The rest of the recipe, including the sugars, acids, flavors, and colors, stays largely the same regardless of which gelling agent is used.
