What Temperature Should Be Set for Fruit Display Chillers?

The main purpose of using a display chiller in supermarkets or fruit shops is to provide an optimal environment to extend the freshness of fruits while also enhancing the store’s visual appeal. This helps create a pleasant shopping experience and can indirectly boost sales. But what is the ideal temperature to set for storing fruits in a chiller fridge? Let’s dive into the details to understand how to maximize fruit preservation.

Ideal Temperature Range for Fruit Preservation

Generally, the temperature for a display chiller should be set between 2 to 10°C (35.6 to 50°F). However, since different fruits have varying temperature requirements, it’s essential to adjust the settings based on the types of fruits you store.

For instance, fruits like apples, pears, and grapes can be stored directly in the display chiller at lower temperatures to maintain their freshness. However, each type of fruit has its optimal preservation temperature. In supermarkets and fruit stores, it is often impractical to store only one type of fruit in a single chiller. As a solution, it’s best to set the chiller at an average temperature that suits multiple types of fruits to achieve a balanced preservation effect.

Cold-Climate vs. Tropical Fruits: Understanding Their Differences

Cold-Climate Fruits

Fruits that grow in colder regions or ripen in autumn tend to be more tolerant of low temperatures. Storing them in a chiller fridge helps preserve their freshness by limiting the activity of microorganisms that cause spoilage. Examples include apples and pears, which can thrive in cooler storage environments.

Tropical Fruits

On the other hand, tropical fruits, such as bananas, mangoes, and pineapples, are sensitive to cold temperatures. Placing these fruits in a chiller fridge may cause chilling injuries, resulting in unsightly black or brown spots on the surface. These dark patches indicate that the fruit has suffered cold damage, which leads to nutrient loss and accelerates spoilage. In some cases, the fruit’s flesh may deteriorate and start rotting within a few days if not properly stored.

Therefore, it’s recommended to store tropical fruits in a cool, shaded area away from direct sunlight rather than in a refrigerator or chiller. This helps maintain their quality and prevents cold damage.

Practical Tips for Using a Display Chiller for Fruits

• Temperature Settings: For a mix of fruits, set the chiller to a temperature range of 4 to 6°C (39.2 to 42.8°F). This range is generally safe for most fruits without causing damage to tropical varieties.
• Humidity Control: Fruits generally require higher humidity levels to prevent dehydration. If your display chiller has humidity control features, aim for a relative humidity level of 85-90%.
• Proper Organization: Place fruits with similar temperature and humidity requirements together. For example, keep apples and pears in one section, while avoiding placing tropical fruits like bananas in the chiller.

Conclusion

The appropriate temperature setting for your commercial refrigerator depends on the types of fruits you are storing. Cold-tolerant fruits can benefit from lower temperatures, while tropical fruits require more moderate, non-chilled environments to avoid damage. By setting the right temperature and organizing your fruits efficiently, you can prolong their shelf life and reduce waste.
