Freeze-drying Skittles, such as freeze dried rainbow, freeze dried worm and freeze dried geek, and other similar candies is a popular trend, and one of the most striking effects of this process is the way Skittles often "explode" or puff up during freeze-drying. This explosive transformation is not just for show; it’s a fascinating result of the physics and chemistry involved in freeze-drying.
The Structure of a Skittle
To understand why Skittles explode when freeze-dried, it’s important to know a bit about their structure. Skittles are small, chewy candies with a hard sugar shell on the outside and a softer, more gelatinous interior. This interior contains sugars, flavorings, and other ingredients that are tightly bound together with moisture.
Freeze-Drying and the Role of Moisture
When Skittles are freeze-dried, they undergo the same process as other freeze-dried foods: they are first frozen, and then placed in a vacuum chamber where the ice within them sublimates, turning directly from a solid to a gas. This process removes almost all the moisture from the candy.
During the freezing stage, the moisture within the chewy center of the Skittle turns into ice crystals. As these crystals form, they expand, creating internal pressure within the candy. However, the hard outer shell of the Skittle does not expand in the same way, leading to a buildup of pressure inside.
The "Explosion" Effect
As the freeze-drying process continues, the ice crystals within the Skittle subliminate, leaving behind air pockets. The pressure from these expanding air pockets pushes against the rigid shell. Eventually, the shell cannot contain the internal pressure, and it cracks or bursts open, creating the characteristic "exploded" appearance of freeze-dried Skittles. This is why, when you look at freeze-dried Skittles, they often appear puffed up, with their shells split open to reveal the expanded interior.
The Sensory Impact
This explosion not only alters the appearance of Skittles but also transforms their texture. The freeze-dried Skittles become light and crunchy, a stark contrast to their original chewy consistency. The flavor is also intensified due to the concentration of sugars and flavorings, making freeze-dried Skittles a unique and delicious treat.
The "explosion" effect adds to the fun and appeal of freeze-dried Skittles, making them a popular choice among those who enjoy freeze-dried candies. Richfield Food’s freeze-drying process enhances these qualities, ensuring that their freeze-dried candies, including Skittles, deliver an exciting and flavorful experience.
Conclusion
Skittles explode when freeze-dried due to the pressure created by the expansion of ice crystals within their chewy centers. This pressure eventually causes the hard outer shell to crack open, leading to the characteristic puffed-up appearance of freeze-dried Skittles. This transformation not only makes the candy visually interesting but also enhances its texture and flavor, offering a delightful and novel way to enjoy a classic treat.
