Preserving what makes microgreens special

Freeze drying

Microgreens contain concentrated, delicate phytonutrients. To preserve them and get them to you, we use freeze-drying, a vacuum freeze-drying process that retains up to 98% of their nutrients.

The freeze-drying process

Flash freezing

Flash freezing

The fresh product is flash-frozen at a very low temperature.
This step sets the cellular structure and prevents the degradation of vitamins, enzymes, and sensitive compounds.
It is the basis for high-quality preservation.
Preserve from the very first second
Vacuum sublimation

Vacuum sublimation

Under a vacuum, frozen water passes directly from ice to vapor.
There is no liquid phase, no cooking, and no significant nutritional loss.
This is how the integrity of the food and its original profile are preserved.
Remove water without heat
Stability and purity

Stability and purity

Residual moisture is removed to very low levels.
The result is a stable, preservative-free ingredient with a high concentration of nutrients and a long shelf life.

Easy to use, concentrated and true to the food

When using a freeze-dried product, you will notice that your food retains the original flavor of the vegetable, with no cooked or bitter notes, and has a light texture that dissolves quickly upon contact with a liquid medium. Thanks to its porous structure, it rehydrates homogeneously and integrates easily into water, smoothies, or yogurt, without clumps or a heavy feeling. Its low water activity guarantees a stable and consistent experience over time, allowing for simple, repeatable use that is compatible with a daily routine.
What it preserves

What it preserves

Freeze-drying preserves the most sensitive compounds in microgreens. By working at low temperatures and without liquid water, it limits the degradation of thermolabile vitamins, active enzymes, and delicate phytonutrients, while maintaining the food's natural matrix.
Heatless preservation
What it is not

What it is not

Freeze-drying is not an extraction process. It does not create nutrients or transform the food: it preserves what is already there, without reformulating it.
It does not transform, it preserves

Frequently Asked Questions

How does freeze-drying work? +

Freeze-drying removes water from food without heat. The microgreens are first rapidly frozen at –40 °C. Then, under vacuum, the ice turns directly into vapor without passing through a liquid phase. The water is removed; the nutrients remain.

The result is a stable powder, free from preservatives and additives, that preserves more than 95% of the nutritional value of fresh microgreens.

Is freeze-drying better than traditional drying? +

Yes. As it is carried out at low temperature and under vacuum, freeze-drying limits the thermal and oxidative degradation of sensitive compounds and nutrients compared to heat-based methods.

Is a lyophilized product an extract or a concentrate? +


No. A freeze-dried product is whole food from which the water has been removed. Specific compounds are not isolated or concentrated, although the removal of water reduces the volume and makes the nutrients much more densely present, at the same weight.

Does freeze-drying change the nutritional value of microgreens? +

It does not create or modify it. Its function is to preserve, as much as possible, the natural profile of the food as it exists in the fresh microgreen.
