#22 - Freeze-Drying & The Future of Food Security - David Leaman

Can freeze drying help solve some of the biggest challenges in food and nutrition?

In this episode, David Leaman, freeze-drying content creator and strategic partner, takes us inside the science, business, and real-world applications of freeze drying — a preservation method that retains up to 97% of nutrients while dramatically cutting down on food waste.

We look at how freeze-dried powders can make kids’ meals more nutrient-dense, how farmers and grocery stores can save unsold produce, and why entrepreneurs are experimenting with everything from candy and chia pudding to pet treats and survival food.

David also shares the growing need for industry advocacy — from educating lawmakers to building food safety standards — to ensure freeze drying plays a bigger role in tackling waste and improving access to healthy food.

This conversation connects preservation technology with global food security, showing how innovation at the kitchen counter can ripple out to farms, businesses, and even public policy.
