What is freeze drying?
But freeze drying is the only method that does this fast—without heating the food. The process of freeze drying preserves aromas and color compounds and makes food taste almost as good as fresh. Freeze drying removes water through two phases of water: freezing and sublimation.
Why are pop tarts still good after freeze drying?
Mostly, that is because they didn’t have enough moisture for the process to effect change.
What is the second phase of a freeze dryer?
The second phase in a freeze dryer—sublimation—reduces the pressure around the food to as low as possible. Typically, ice needs to melt before it can turn into a gas—evaporation. However, if you reduce the pressure around the food low enough, that solid ice turns straight to gas.
Why does lettuce turn black when it freezes?
(You may have heard of it.) Water expands about 9% when it freezes. Even that small an expansion will damage the cell walls in some foods. This is why your lettuce turns black and floppy when it freezes in the crisper drawer. The faster the water in the food freezes, the less damage will occur in the food.

Why does my freezer burn?
Freezer burn occurs when moisture leaves frozen food, leaving desiccated patches where the food turns leathery or mealy. Any food can develop freezer burn when it stays in your freezer too long, but it's likelier to happen when you refreeze food after thawing it. Thawing allows ice to melt back into water; when you freeze the food again, that water turns into larger ice crystals that tear food apart from the inside, exposing more of the damaged cells to the arid atmosphere of your freezer and leaving it more susceptible to freezer burn.
What happens when you thaw ice crystals?
Large ice crystals degrade the textures of food, and refreezing a thawed product creates larger crystals. The characteristic crunch of a bell pepper and the juiciness of a steak are both the result of the foods' cellular structures. When these cells rip apart under the force of expanding ice crystals, the food turns into mush.
What temperature is safe to thaw food?
While safe thawing methods that take place outside of what the U.S. Department of Agriculture calls the "danger zone" -- between 40 and 140 degrees Fahrenheit -- don't generally give bacterial contamination a chance to happen, there's always a possibility that a portion of the food could reach that danger zone despite your care.
