Freeze-drying

Preserve what makes microgreens special.

Microgreens are packed with delicate phytonutrients. To preserve them and get them to you, we use freeze-drying, a vacuum freeze-drying process that retains more than 95% of their nutritional value.

The process

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.
Lightweight, stable, focused

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, without cooked or bitter notes, and has a light texture that dissolves quickly upon contact with a liquid. Thanks to its porous structure, it rehydrates evenly and blends 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 easy, repeatable use that is compatible with a daily routine.

What preserves and what is not

Preserve, do not transform.

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 heat-labile vitamins, active enzymes, and delicate phytonutrients, 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

Any questions?We have answers.

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. Carried out at low temperature and under vacuum, freeze-drying limits the thermal and oxidative degradation of nutrients and sensitive compounds, compared with heat-based methods.

Is a freeze-dried product an extract or a concentrate?

No. A freeze-dried product is the whole food with the water removed. No specific compounds are isolated or concentrated. When the water is removed, the volume shrinks and, weight for weight, the nutrients are much more densely present.

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.

Is 1 g per day enough?

It may seem small. But microgreens are naturally highly concentrated in phytonutrients, and freeze-drying removes only the water, not the compounds themselves.

What remains is the whole plant, with its phytonutrient matrix intact, concentrated through freeze-drying.

One gram of SYNERGIC concentrates the equivalent of more than fifteen times its fresh weight.
