Freeze drying — scientifically known as lyophilisation— is a precise preservation process that gently removes water from food while keeping its structure and nutrients intact. First, ingredients are frozen at very low temperatures, then placed under a deep vacuum where the ice turns directly into vapour (a process called sublimation). Because the food never passes through a liquid stage, essential proteins, vitamins, and natural enzymes remain stable and bioavailable.
1.
Fresh or cooked foods are flash
frozen, then placed in a vacuum
chamber.
2.
About 98% of the food's moisture is
drawn off by evaporating the ice, at
temperatures as low as -10°C.
3.
The food retains its original fresh
flavour, aroma and nutrients.
4.
We are ready to serve!
This technology locks in up to 98% of nutrients, while maintaining the original flavour, colour, and aroma of fresh food — without the need for heat, fillers, or artificial preservatives.
Raw meat diets frequently contain pathogens such as Salmonella, Listeria, Campylobacter, and pathogenic E. coli, posing risks to both pets and humans. Freeze-dried diets, due to their very low moisture content, demonstrate reduced pathogen survival, making them safer at the point of feeding.
Freeze-dried diets are shelf-stable, lightweight, and require no refrigeration, making them convenient for daily use and travel. Raw diets, in contrast, demand freezer space, thawing, and strict hygiene protocols to mitigate food safety risks.
At Pure Life, we include real freeze-dried pieces in every recipe to deliver the benefits of raw nutrition in a convenient dry format. These pieces arerich in high-quality single-animal proteins and superfoods, giving dogs and cats a nutrient-dense boost that supports energy, digestion, and overall vitality.
