Refrigerator zones

The refrigerator door (frequent temperature fluctuations from +5°C to +15°C): The refrigerator door is the warmest zone of the fridge, so it should be used to store items with a naturally longer shelf life.

What to store there: Foods with higher levels of acidity and salt, as well as those that contain preservatives. This includes:

• butter
• sesame oil
• beer & wine
• juice
