What is the filling inside Skittles?

5 min read

Most people assume Skittles have a liquid center, but the interior consists mainly of a chewy core. The filling inside Skittles is a blend of sugar, corn syrup, and hydrogenated palm kernel oil, with added flavors. This creates the distinctive, solid-but-chewy texture loved by many.

Quick Summary

The chewy center of Skittles is composed of sugar, corn syrup, and hydrogenated palm kernel oil, along with natural and artificial flavors. Unlike a liquid or jelly filling, this substance gives the candy its signature soft bite beneath the hard, colorful shell.

Key Points

  • Chewy Core: The filling of a Skittle is not liquid but a solid, chewy center made from a mix of sugar, corn syrup, and hydrogenated palm kernel oil.

  • Flavor Incorporation: Flavors are not injected but blended directly into the chewy core, with each core having its own unique taste.

  • Panning Process: The candy is formed by starting with the chewy core and building the hard, colorful shell in layers using a rotating drum called a 'pan'.

  • Vegetarian-Friendly: Since 2009, Skittles have removed animal-derived gelatin and shellac, using a plant-based carnauba wax for their shine.

  • No Injected Filling: The manufacturing method differs from other candies like chocolates, as it creates the core first and then adds the shell.

  • Texture Science: Hydrogenated palm kernel oil is a key ingredient that gives the core its solid-yet-chewy consistency at room temperature.

Decoding the Chewy Center of Skittles

When you bite into a Skittle, the combination of the hard, crunchy shell and the soft, chewy inside is instantly recognizable. However, contrary to popular belief and the classic "Taste the Rainbow" slogan, the filling is not a liquid burst of flavor. The magic is in the chewy core, which is a carefully crafted combination of ingredients that gives the candy its texture and concentrated fruity taste. The manufacturing process ensures that this chewy center is uniformly produced before being coated with its vibrant, sugary shell.

The Key Ingredients of the Chewy Filling

The main components of the Skittles filling are common confectionery ingredients designed to create a specific texture and flavor profile. The primary ingredients include sugar, corn syrup, and hydrogenated palm kernel oil.

  • Sugar and Corn Syrup: These are the base sweeteners that provide the core's foundational taste and texture. The combination helps create the chewy, malleable consistency.
  • Hydrogenated Palm Kernel Oil: This ingredient is crucial for creating the solid but pliable core. The hydrogenation process solidifies the oil at room temperature, which is essential for the candy's stability and texture. It gives the filling its specific density, preventing it from being liquid or too hard.
  • Citric Acid: Adding a characteristic tanginess, citric acid provides the fruity sourness that complements the sweetness.
  • Flavors and Colors: The distinctive fruit flavors (like strawberry, lemon, and grape) are added through a precise blend of natural and artificial flavors. These are carefully mixed to ensure each candy core has a distinct taste.

How the Filling is Made: A Panning Process

The creation of Skittles is a multi-step manufacturing process that doesn't involve injecting a filling into a shell. Instead, it starts with the center and builds the outer layers from there.

  1. Core Creation: Ingredients like sugar, corn syrup, and hydrogenated palm kernel oil are mixed and heated until they form a thick, paste-like batter.
  2. Shaping the Core: The batter is poured into molds and cooled to create small, pliable, toffee-like pellets, which will become the chewy core of the candy.
  3. Panning: This is the critical step. The cores are placed in large, rotating drums called "pans". As they tumble, colored, and flavored sugar syrup is slowly added, coating each core in a thin, uniform layer. This process is repeated multiple times, sometimes for several hours, to build up the hard, colorful outer shell.
  4. Polishing: After the final shell layer is dry, a carnauba wax is added to the pan to give the candies their glossy, trademark shine.

This method explains why Skittles don't have a hollow center or a burst of liquid—the "filling" and the "shell" are built upon a single, solid foundation. The flavor isn't injected; it's incorporated into the core mixture from the start.

Conclusion

The secret behind the filling inside Skittles is not a hidden, liquid core but rather a chewy, fruity center made from a consistent mixture of sugar, corn syrup, and hydrogenated palm kernel oil. This core is built up layer by layer with a hard, colorful sugar shell through a meticulous panning process. Understanding this reveals the fascinating food science behind the classic candy and explains why each bite offers a uniform taste and texture, giving life to the iconic "Taste the Rainbow" experience.

Are Skittles Vegetarian and Vegan Friendly?

In 2009, Skittles adjusted their recipe to remove animal-derived gelatin and shellac, making them suitable for vegetarians and vegans in many regions. The primary waxy coating used now is carnauba wax, a plant-based alternative. However, specific ingredient formulations can vary slightly by region and product line, so it's always wise to check the packaging.

Frequently Asked Questions

What is the chewy center of Skittles made of?

The chewy center of a Skittle is primarily composed of sugar, corn syrup, and hydrogenated palm kernel oil. These ingredients are combined with natural and artificial flavors to give each piece its distinctive taste.

Does the filling inside Skittles contain fruit juice?

Yes, the chewy core of Skittles typically contains fruit juice, along with natural and artificial flavors, to enhance the fruity taste of the candy.

Is the filling inside Skittles liquid?

No, the filling inside Skittles is not a liquid. The core is a solid, pliable, and chewy consistency created using ingredients like hydrogenated palm kernel oil.

How do they get the 'S' on the outside of the Skittles?

The letter 'S' is printed on the hard, sugary shell of the candy during the manufacturing process. After the candies are coated and polished, they pass through a machine that prints the logo.

Why do Skittles have a hard shell and a soft filling?

The hard shell is built up in multiple layers of sugar and syrup through a process called panning, while the soft, chewy core is made separately and then coated. This two-part construction is what gives Skittles their unique texture.

Do Skittles contain any animal products?

Since 2009, Skittles in many regions are made without animal-derived gelatin or shellac and use plant-based carnauba wax, making them suitable for vegetarians and vegans. Always check the specific packaging for the most current information.

What is the process that gives Skittles their shiny coating?

After the colored sugar shells are added during the panning process, the candies are polished with carnauba wax. This plant-based wax provides the final, glossy finish and helps seal the shell.
