1. AEF technology A new way to preserve vegetables
Shelfer, LLC

2. The problem with conventional freezing
Conventionally frozen products are perishable, their cell structure is damaged, during further storage products lose moisture and become frosted outside.
Rapid freezing (including the IQF system) has the same problems
As a result, conventionally frozen products have different taste and structure than fresh produce. After 1-2 month of storage, product quality significantly deteriorates due to ice self-creation from glass-type water inside the product.
Conventional rapid freezing process (photo under microscope): cells of the product are damaged

3. Acoustic Extra Freezing (AEF)
During the AEF process, acoustic waves create millions of microscopic ice crystals which are significantly smaller than cell size. As a result, cell structure remains intact.
The technology was initially used only for freezing produce for spaceships and submarines in order preserve the original quality of vegetables.
The AEF products are made available for households and HoReCa businesses. The quality and taste of AEF products is almost identical to fresh ones while the price is almost the same as for conventionally frozen products.
AEF method allows to keep the product’s cells undamaged (photo under microscope)

4. AEF frozen vs conventional
The AEF system allows freezing fruits and vegetables without damaging the cell structure. Vegetables frozen with the AEF technology retain their natural flavour and fresh smell.

7. Conventionally frozen potato slices
Conventionally, potato slices are pre-fried in vegetable oil during production.
This is done because shock freezing destroys the product’s structure, and in order to prevent it from falling apart, potato slices are enclosed in a "cocoon" of fried crust.
As a result, ordinary store-bought slices are not suitable for boiling and should not be defrosted before cooking.

8. AEF potato slices
Our potato slices have no preservatives, oil or ice unlike our competitors’ products.
AEF technology preserves cell structure so there is no need for pre-frying.
Taste the difference, it is almost like it was never frozen.

10. What makes us different?
It is impossible to taste the difference between AEF frozen potatoes and fresh ones. This allows HoReCa businesses to significantly cut costs since they can simply take our potatoes and start cooking.
We are ready to offer other AEF frozen products. A multitude of fruits and vegetables will be available after their growing season
Many vegetables and fruits (like tomatoes) are harvested when they are underripe for better storage. However, we buy fruits and vegetables when they are ripe. This allows us to offer unparalleled taste when it’s not their growing season
Our products are made from local vegetables and our prices are formed based on the prices of local produce.
AEF technology is also suitable for fish and meat.
We are ready to produce other AEF frozen products on request or sell the AEF technology.

11. Purchase your own AEF system
The AEF system can be installed inside existing quick-freeze cameras or as a separate module.
The AEF system’s price starts from USD (without the freezer system).
Freezer system cost nearly USD can be used one of existing or produced new one. For this money AEF system can freeze 5000 – 6000 kilo different food.
AEF vegetables are already available in stores like Metro C&C
Fully tested, approved trademark for HoReCa
AEF freezed vegatables must be cooked from frozen form.
AEF fish and meet can be defrosted and used or solded in retail as fresh, because quality of this type of product stay not changed during warming.
