Preserving what makes microgreens special

Freeze drying

Microgreens are packed with delicate phytonutrients. To preserve them and get them to you, we use freeze-drying , a vacuum-sealed drying process that retains up to 98% of the nutrients.

Instant freezing

Instant freezing

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

Vacuum sublimation

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

Stability and purity

Residual moisture is removed to very low levels.
The result is a stable ingredient, without preservatives, 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'll notice that your food retains the vegetable's original flavor, without any 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 lumps or a heavy feeling. Its low water activity ensures a stable and consistent experience over time, allowing for simple, repeatable use that fits seamlessly into a daily routine.

What preserves

What 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-sensitive vitamins, active enzymes, and delicate phytonutrients, maintaining the food's natural matrix.
Heat-free preservation
What it is not

What it is not

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

Frequently Asked Questions

¿Cómo funciona la liofilización? +

La liofilización es un proceso que extrae el agua de los alimentos sin aplicar calor, lo que permite conservar casi intactos sus nutrientes, sabor y estructura natural.

Primero, los microgreens se congelan rápidamente a -40ºC. Después, en una cámara de vacío, el hielo pasa directamente de sólido a vapor (sublimación) sin convertirse en líquido. Al eliminar el agua de esta forma, los nutrientes quedan estables, concentrados y protegidos, sin necesidad de aditivos ni conservantes.

El resultado es un polvo ligero y potente que mantiene más del 95% del valor nutricional del alimento fresco.

¿La liofilización es mejor que el secado tradicional? +

Sí. Al realizarse a baja temperatura y bajo vacío, la liofilización limita la degradación térmica y oxidativa de compuestos sensibles, nutrientes, en comparación con métodos basados en calor.

¿Un producto liofilizado es un extracto o un concentrado? +


No. Un producto liofilizado es el alimento completo al que se le ha retirado el agua. No se aíslan ni se concentran compuestos específicos, aunque la eliminación del agua reduce el volumen y hace que, a igualdad de peso, los nutrientes estén mucho más densamente presentes.

¿La liofilización cambia el valor nutricional del microgreen? +

No lo crea ni lo modifica. Su función es preservar, en la medida de lo posible, el perfil natural del alimento tal como existe en el microgreen fresco.
