Why Low-Temperature Drying Matters

Dehydration is one of the oldest ways to preserve food, but not all drying is equal. The temperature at which produce is dried decides how much of its original nutrition, colour, and flavour survives the process.

Many heat-sensitive vitamins — vitamin C, several B vitamins, and a range of antioxidants — begin to break down well below boiling point. Push the temperature up to dry faster and you trade nutrition for speed.

At HarvestVita we dry at controlled, low temperatures. It takes longer and yields less per batch, but the powders and flakes that come out still carry the pigment, aroma, and micronutrients of the produce they came from.

The simplest test is colour. A beetroot powder that is deep crimson, not dull brown, tells you the pigment — and the betalains alongside it — made it through intact.
