In recent years, the global demand for frozen fruits has been on the rise, with consumers increasingly concerned about the quality and freshness of these products. Among them, high - quality frozen blackberries have gained significant popularity in the international market. However, ensuring the quality of frozen blackberries during the export process, especially in cold - chain transportation, is crucial. This article will unveil the technical knowledge of each link in the cold - chain transportation of high - quality frozen blackberries.

Advantages of High - Quality Frozen Blackberries

High - quality frozen blackberries are carefully selected from premium growing regions. For example, regions with abundant sunlight and appropriate soil conditions can produce blackberries with high sugar content and rich flavor. These blackberries are strictly screened during the selection process. Only those with a size error of no more than ±5mm and no visible damage are selected, ensuring a high whole - fruit rate. In fact, the whole - fruit rate of our high - quality frozen blackberries can reach over 95%.

After selection, the blackberries undergo a rapid freezing process. This advanced freezing technology can lock in the nutrients and freshness of the blackberries within 30 minutes, maintaining the original texture and flavor of the fruit. As a result, these frozen blackberries can provide consumers with a taste experience similar to fresh blackberries.

Cold - Chain Transportation Links

Vehicle Selection

Selecting the right cold - chain transport vehicle is the first step. The vehicle should have excellent insulation performance, with a heat transfer coefficient of less than 0.4W/(m²·K). This can effectively reduce the impact of external temperature on the temperature inside the vehicle. For long - distance transportation, vehicles equipped with redundant refrigeration systems are preferred to prevent refrigeration failures during transportation.

Loading

During loading, the frozen blackberries should be stacked neatly to ensure good air circulation inside the vehicle. The stacking height should not exceed 80% of the vehicle's internal height to avoid excessive pressure on the bottom blackberries. At the same time, a buffer layer should be placed between the blackberries and the vehicle wall to prevent direct contact with the cold wall and damage to the fruit.

Temperature Monitoring

Throughout the transportation process, the temperature inside the vehicle must be continuously monitored. The temperature should be maintained between -18°C and -22°C. Any temperature deviation can lead to quality problems. For example, if the temperature rises above -18°C, the blackberries may start to thaw slightly, resulting in cell damage and affecting the taste and texture.

Route Selection

When choosing a transportation route, factors such as traffic conditions, road quality, and weather should be considered. Routes with less traffic congestion and fewer road bumps can reduce the risk of damage to the blackberries. In addition, avoid routes passing through areas with extremely high or low temperatures to minimize the impact on the vehicle's internal temperature.

Destination Handling

Upon arrival at the destination, the frozen blackberries should be quickly transferred to a suitable cold storage environment. The transfer process should be completed within 30 minutes to prevent temperature fluctuations. The cold storage temperature should also be maintained between -18°C and -22°C.

Successful Case

A European food processing company once imported our high - quality frozen blackberries. By strictly following the above cold - chain transportation details, the quality of the blackberries was well - maintained during transportation. After receiving the goods, the company found that the whole - fruit rate of the blackberries was still above 93%, and the flavor and texture were excellent. This enabled them to produce high - quality blackberry products, which were well - received in the market and increased their sales by 20% compared to the previous year.

In conclusion, paying attention to every detail in the cold - chain transportation of high - quality frozen blackberries is of great significance. It can not only effectively guarantee the quality of the blackberries but also provide high - quality raw materials for subsequent processing and sales. Whether you are a food processing company or a distributor, choosing our high - quality frozen blackberries and following strict cold - chain transportation processes will bring you more market opportunities and higher profits.
