Freeze-drying – how does fresh green juice become a practical product?

When we think of green juice, we usually imagine a freshly squeezed drink that should be consumed shortly after preparation. But what if we want to preserve the properties of such a product in a more practical form, without applying the high temperatures characteristic of some classic drying methods?

This is where we come to freeze-drying – a technology used in the food, pharmaceutical, and other industries precisely when it is important to carefully remove water from a product.

In our products, this process has a special place, because it allows us to obtain a stable, practical product suitable for everyday use from freshly squeezed spelt green juice.

But what actually happens during freeze-drying?

What is freeze-drying?

Freeze-drying, also known as lyophilization, is a process in which the product is first frozen, and then water is gradually removed from it under reduced pressure conditions.

The special feature of this technology is that it allows for the drying of products without the need for classic intensive heating.

In classic drying, the product is often exposed to elevated temperatures to remove water. Freeze-drying allows for a different way of processing, which is why it is particularly interesting when we want to best preserve the characteristics of sensitive products.

It all starts long before freeze-drying

The quality of the final product does not only depend on the machine in which the freeze-drying is performed.

In the case of spelt green juice, the story begins with the plant itself.

The young green spelt leaf is used, and after the plant reaches the appropriate stage of development, harvesting begins. The time between harvesting and further processing is kept to a minimum.

The young leaf is then squeezed to obtain fresh green juice.

This detail is precisely what is important: we do not freeze-dry the ground plant or the spelt grain, but the previously obtained green juice.

Only after that does the process begin by which the fresh juice will take on a completely different form.

From green juice to fine powder

Fresh spelt green juice contains a high percentage of water. During freeze-drying, the juice is frozen, and then, under controlled conditions and vacuum, the water is gradually removed.

When the process is finished, instead of liquid green juice, dry matter in the form of powder remains.

That is freeze-dried spelt green juice.

This form has one very practical advantage: it is no longer necessary to grow the plant every day, pick young leaves, squeeze them, and consume the fresh juice immediately.

The freeze-dried form allows the product to be more easily stored, transported, dosed, and integrated into an everyday routine.

Why are low temperatures important?

Temperature is one of the important factors in food processing.

Certain components of food can be sensitive to heat, which is why the processing method can affect the characteristics of the final product.

This is precisely one of the reasons why freeze-drying is valued as a technology for processing sensitive materials. Water removal takes place without the classic intensive heating of the product required by some other drying methods.

Freeze-drying is a technology that aims to best preserve the quality of the starting material, while simultaneously obtaining a more stable and practical product.

Why is it not enough just to write “freeze-dried”?

Freeze-drying is an important part of production, but the word itself on the packaging is not a guarantee of quality.

It matters what the raw material was like, in what conditions the plant was grown, when it was harvested, how much time passed until processing, how the juice was squeezed, how the freeze-drying process itself was controlled, and how the finished product is stored.

That is why quality should be viewed as a chain of connected steps.

If the starting material is not of appropriate quality, the technology that comes later cannot simply “create” quality that did not exist at the beginning.

When technology makes nature more practical

Modern technology and natural products do not have to be opposites.

Freeze-drying is a good example of how technology can help a product that is demanding to store and prepare daily in its fresh state take on a form adapted to a modern lifestyle.

In the case of our products, everything begins with a young green leaf, continues with the squeezing of fresh green juice, and freeze-drying creates a practical form that is further used in production.

So when you next read the phrase “freeze-dried spelt green juice“, you will know that an entire technological process stands behind that short formulation.

Because the quality of the finished product does not begin with the last step of production.

It is built from the plant to the finished product – step by step.
