How freeze-drying keeps nutrients

Fresh fruit is mostly water. Freeze-drying freezes the fruit, then removes ice by sublimation (water jumps straight from solid to vapour) under vacuum. The result is very light, shelf-stable, and energy-dense per gram. Because heat exposure is gentler than many hot-air drying methods, colour, aroma, and heat-sensitive vitamins often fare well — though no process preserves everything perfectly.

Why the process matters

Good freeze-drying is a balance of temperature, pressure, and time. Rushing or cutting corners can darken fruit or blunt flavour; careful runs keep the fruit’s own sugars and acids in the spotlight.

How to think about portions

A small handful of freeze-dried fruit can equal a much larger volume of fresh fruit in sugar and calories — not automatically bad, but worth knowing when you’re budgeting snacks for kids or weight goals.
