How does a freeze-drying machine change the taste of traditional candies?

Can gummy candies also become crispy snacks? The originally chewy and crunchy candies, after undergoing freeze-drying processing, become fluffy and crispy, and even significantly expand in size. Freeze-dried rainbow candies, freeze-dried cotton candies, freeze-dried rubber candies, freeze-dried chocolate, and other novel foods, for candy processing enterprises, using freeze-drying machines to develop crispy candies can enrich product varieties and expand the snack market for leisure.

Different from traditional fruit and vegetable freeze-drying, candy processing is not only about removing water, but more importantly, it is about changing the original texture. The freeze-drying machine uses a vacuum environment and temperature control to cause some candies to expand their internal gases, vaporize water, and form a loose and porous crispy structure. For candies with a high sugar content and less freezeable water, their expansion mainly comes from the physical changes under vacuum conditions, rather than the traditional ice crystal sublimation.

After being processed by the freeze-drying machine, different candies can achieve different product effects. For example, rainbow candies may expand and form a crispy shell, cotton candies become light and brittle, and some rubber candies form a fluffy internal structure.
