The Advantage
Four reasons producers choose freeze drying.
Long-lasting storage
A shelf life of up to 25 years — ideal for long-term food storage and biological or medical samples.
Preserves nutrition
Retains vitamins and nutrients far better than air drying or oven drying, keeping foods genuinely healthier.
Keeps food fresh
Looks and tastes fresh when rehydrated — well suited to camping, hiking and other outdoor use.
Lightness
Much lighter than fresh or frozen equivalents, making product easier and cheaper to transport.
