Freeze-drying removes water from a frozen product at reduced pressure. For sweets, the most noticeable result is texture: a familiar candy or gummy becomes dry and brittle. At Frizle we process the sweets ourselves in a freeze dryer.
What is sublimation? ❄️
In a conventional cycle, the product freezes first. Pressure in the chamber is then reduced. Under these conditions, ice can turn into vapour without an intermediate liquid stage. This is called sublimation.
The conventional process is not a universal instruction for every sweet. Equipment can have separate candy programmes, and the cycle and settings depend on the product. We do not give one temperature or duration as a recipe for every bag.
What do vacuum and controlled heating do? ⚙️
A pump reduces pressure while the machine controls drying conditions. Supplying heat helps remove moisture. This differs from leaving sweets in an ordinary freezer, which does not operate under vacuum.
Ingredients and structure affect the result. Chewy candy and gummies can expand and crack. In bars, caramel or nougat fillings change most. Ingredients do not all respond in the same way, so a gummy and a chocolate coating will not produce identical results.
Why do sweets become crunchy? 🍬
Many processed products have a dry, porous structure. Instead of stretching when chewed, they break and crumble more easily. The extent depends on the type of sweet. Read examples in which sweets can be freeze-dried.
You can compare Skittles or gummies with their ordinary versions. This is a texture comparison. It does not mean the freeze-dried product contains less sugar or fewer allergens.
How long does processing take? ⏱️
There is no single duration for the whole range. Product type, piece size and machine settings all matter. Processing time is also separate from a shop’s dispatch promise: dispatch within 24 hours of payment concerns order fulfilment.
Why does packaging matter? 📦
The dry structure readily absorbs moisture from its surroundings. We therefore pack sweets in sealed packaging. After opening, reseal the bag after each use. Contact with moist cream or yogurt gradually takes away the crunch.
Check storage conditions and the date on the label. Read practical advice in how to store freeze-dried sweets.
Ingredients after freeze-drying 📋
Processing does not remove sugar, gelatin or allergens. Read the ingredients for the chosen flavour. If nutrition figures come from the label before freeze-drying, their source should be identified beside the table. Removing water changes mass, so starting-product figures should not be presented without explanation as measurements of the finished bag.
