Flash freezing of berries

Shock freezing of berries is a method of rapid freezing in which berries are exposed to extremely low temperatures (-30°C and below). As a result, the berries freeze almost instantly, which allows them to retain their texture, taste, color, nutrients, and vitamins.

Types of berries suitable for shock freezing

• raspberries;
• strawberries;
• blueberries;
• cherries;
• currants;
• blackberries.

Shock freezing of raspberries

Raspberries are one of the most popular berries for shock freezing. Thanks to the high freezing speed, raspberries retain their structure and taste. This is especially important when using raspberries in desserts, yogurts, and smoothies.

Shock freezing of strawberries

Strawberries are another berry that is perfectly suited for shock freezing. Due to this technology, strawberries preserve their sweetness and aroma. Frozen strawberries can be used in cooking all year round, which makes them indispensable in the food industry.

Frequently Asked Questions

How can I prevent berries from sticking together after freezing?

To prevent berries from sticking together, they must be frozen immediately after harvesting with no excess moisture on the surface. It is also important to ensure intense cold air circulation and not to exceed the recommended layer thickness when loading the container, so that the ice crystal formation stage is passed quickly.

Can I rent a container for the harvest season?

Yes, Global Container Service offers shock containers for rent during the seasonal berry harvest, when the need for refrigeration capacity increases for a limited period. Renting a container allows you to avoid large capital expenditures and quickly scale up processing volumes during peak harvest activity.

Can the container be installed near the harvesting site?

Thanks to their mobility, shock‑freezing containers can be installed directly next to berry receiving or collection points. This approach reduces the time between harvesting and freezing and lowers the risk of quality loss.

Can different types of berries be frozen at the same time?

Freezing different types of berries together is permissible if they have the same temperature and processing requirements, ensuring uniform cooling of each batch.

What temperature is considered optimal for shock freezing berries?

The optimal temperature for shock freezing berries is between –30 °C and –35 °C. At this temperature, with intense air circulation, berries freeze quickly without ice crystals damaging cell walls, which fully preserves their shape, texture, flavor, and vitamins.
