It all starts in the kitchen.
The meal is prepared entirely like a real recipe with real ingredients.
No ingredients are added raw or dehydrated afterwards.
This is an essential step: if a meal is good to begin with, it will remain so once freeze-dried and rehydrated.
Once the recipe is prepared, the meal is frozen very quickly, going from 0 to -15°C in a few minutes.
This rapid freezing forms small ice crystals that preserve the food's structure and ensure a better texture and a more consistent taste upon rehydration.
Small ice crystals = better texture
The frozen meal is vacuum-sealed in a freeze dryer. It is heated very gently, just enough for the water to pass directly from solid to gas, without ever passing through the liquid state. This phenomenon is called sublimation.
Result: structure, texture, flavors, and nutritional qualities are preserved — and the meal regains its original texture upon rehydration.
Freeze-drying ≠ dehydration
Once freeze-dried, the meal is immediately sealed in airtight packaging, free from oxygen and moisture.
No refrigeration is necessary: the meal can be stored for up to 25 years, ready for adventure or the pantry.
Been disappointed by freeze-dried meals before? We get it. Here's what truly sets SLY apart from other brands.
A SLY meal weighs very little once packed. All you need is a stove, hot water, and a few minutes of patience, and it's ready. For trips lasting from 2 days to several weeks, it's the simplest and most flavorful solution.
A van, a sailboat, a chalet without a fully equipped kitchen: SLY meals adapt to all contexts. They take up little space, are not affected by temperature variations, and can be prepared in minutes with any heat source.
Freeze-drying is not just for adventurers. Having SLY meals in the pantry means a real cooked meal ready in 12 minutes for those evenings when you don't feel like cooking.
SLY meals can be stored for up to 5 years without refrigeration, making them convenient for building up a home reserve without having to regularly restock. This is perfect for power outages, crisis situations, or extended unforeseen events.
Freeze-drying is a technology.
What sets SLY meals apart is how well it's mastered.
100% cooked meals before freeze-drying, no ingredients added afterwards
Ingredients, sometimes raw or dehydrated, added afterwards
Everything made in-house: recipes, production, freeze-drying, packaging
Often outsourced steps
Full control over every technical parameter, for every batch
Limited control over the process and the final outcome
Recipes designed for taste first, technique follows
Recipes designed around process constraints, not taste
Freeze-drying is a preservation method that removes water from food by rapidly freezing it under vacuum. This process preserves taste, texture, and nutrients.
Dehydration uses heat to evaporate water. Freeze-drying, on the other hand, removes water by sublimation under vacuum, at cold temperatures. This preservation process allows for better texture, better taste, and longer shelf life.
No, it's the opposite. By removing water without using heat, freeze-drying preserves flavors and allows the meal to regain a taste very close to the original upon rehydration.
The quality of the result mainly depends on the initial dish. At SLY, each meal is cooked entirely before being freeze-dried.
A freeze-dried meal can be stored for up to 5 years in a cool, dry place. Without water, bacteria and mold cannot grow, so no preservatives are needed.
Yes, it is one of the preservation methods that best preserves vitamins and minerals.
Freeze-drying is a long, energy-intensive process that requires specialized equipment. At SLY, everything is done in-house: recipes, production, freeze-drying, and packaging. This total control comes at a cost, but it also allows us to offer better quality and taste.
