Vacuuming berries

Today I tried to vacuumize raspberries - the idea ended in a fiasco.



As I understand it, the problem is that raspberries, when squeezed, begin to quickly release juice, which interferes with the seal of the bag.

There was no such problem with blueberries, they pumped out the air and soldered perfectly:



Of course, raspberries can be pre-laid out on the board and frozen, then the problem with juice will be solved. But two things stop:

• unnecessary movements;
• the volume increases.

Apparently, you just have to wrap the raspberries in a bag. Or try to wrap it in cling film, just today's the topic prompted an idea.

Chef, not that many unnecessary movements.
Now I am vacuuming field strawberries, they are very ripe and if they are not frozen, they will draw out the juice. I have a Caso300, it has the function of sealing a wet bag, but the juice is a pity.
I put it in a bag and freeze it. After taking out the package, I knock on it, the berries are evenly distributed. I will vacuum. I do everything quickly.

The same problem with blackberries, pre-freezing saves. Or ice jam can be made.

berries are evenly distributed

Freeze exclusively for smoothies. Still, in bags with pre-frozen berries, many voids are formed.

And if you immediately grind and freeze roughly in portioned containers, there are such low ones with smooth walls. You can put one on top of the other. Defrost in the refrigerator for one to two days, for example. This is what I'm going to do this year.

I don't want to grind in advance. Though crushed, let it be stored in the original structure.

I will experiment with semi-freezing. For example, put in the freezer for an hour. So that the berry is not yet stone, but suddenly the juice will no longer run out like that.

frozen berries form a lot of voids.

There is a way out - buy another freezer or chest
We did so, we already bought the fourth (chest) for two refrigerators.
Seriously though, yes, it doesn't draw juice from a frozen berry.

Still, in bags with pre-frozen berries, many voids are formed.

Any berry is frozen in its own way, only experience can choose the desired storage option.
It is optimal to first freeze soft juicy berries in bulk, and then put them in bags (both vacuum and ordinary). The most capricious in storage is raspberry, from freezing it eventually falls apart into small pieces. It is advisable to vacuum it after preliminary freezing. Just do not squeeze too much, it will break.

Experience has come to understand that for the full use of space in the boxes, it is better to store berries in packages in bulk, without vacuum. That is, to put pre-frozen berries in bags, and close the bags not tightly with an ordinary knot, leaving free space. Then, when stacking packages in boxes one by one, the packages do not puff up, but fit as tightly as possible, filling all the voids. I try to stack the packages in piles, according to the names of the berries, then it is convenient to take them and put them back. Thus, there is a "monolithic" filling of the box with berries.
In contrast to vacuum, when the package with berries becomes rigid and puffy, which does not allow the packages to be folded in a monolith, and large quantities of voids remain.

The second reason why not a vacuum: if it is necessary to use a package, it must be opened, which in any case violates the integrity of the package, and the impossibility of then immediately evacuating it. Therefore:
- if small bags, then a lot of voids in the boxes, which eats up space
- if there are large packages, then it also eats up the space with voids, and after opening it will be necessary to vacuum the berries again, in the same package, which is inconvenient. Or take a new bag for vacuum, which will increase the consumption of the film, which is also undesirable.
The storage space is also eaten by wide seams on the bags during vacuumization, which also bulge strongly (which can be clearly seen on the top photo of the first post of the topic)

In general, a personal approach to each berry, each fruit

[Tatiana]

Seriously though, yes, it doesn't draw juice from a frozen berry.

Yes, I tried it. I only held it for one hour in the freezer - the berry remained fresh and soft to the touch, but the juice did not come out like that, everything was vacuumized and sealed normally. But I became on the advice Tatiana just wrap up in small ordinary packages - this really saves space. Probably, vacuumizing for the freezer is unnecessary.

Probably, vacuumizing for the freezer is unnecessary.

This is if the freezing of moisture from the contents does not interfere. As long as there is air, there is also the possibility of transferring steam from berries or vegetables to the colder side of the bag. And the longer such a bag is stored, the more ice forms.

Packages, where the contents after the vacuum sealer are tightly wrapped in foil, do not have frost even after a few years in the freezer.

And the longer such a bag is stored, the more ice forms.

and not only berries ... sliced ​​cucumbers, tomatoes also give frost to the walls of the bag, without a vacuum.

And the longer such a bag is stored, the more ice forms.

Again, experience is the son of our mistakes and ... our own observations and experiments.

Not all types of berries and fruits, vegetables are seized by frost. Personally depends on the type, on the wholeness or in slicing. This can only be determined after observing them.
As a rule, a normal freeze is enough for a year. And there are those that are safely stored and for years without problems.

Yes, sliced ​​vegetables can overgrow with hoarfrost, but if they are whole, they will be stored for years - it has been checked.Therefore, I choose small tomatoes for freezing, very red and ripe, autumn tomatoes that ripen well have never been frozen. Whole tomatoes have no broken film on top, which protects the pulp from problems
