Quick Answer
Short Answer: Fruits like pears, apples, and grapes are more likely to spoil in a buried barrel due to their skin's natural ability to breathe and allow ethylene gas to escape. Berries and tropical fruits like pineapple and mango tend to retain their ethylene gas, speeding up spoilage. Root vegetables like carrots and beets are less likely to spoil.
Choosing the Right Fruits
When selecting fruits for storage in a buried barrel, consider their natural ability to retain or release ethylene gas. Fruits that release ethylene gas, like apples and pears, can be stored for longer periods. However, if you plan to store fruits for an extended period, it’s best to avoid those that tend to retain ethylene gas, such as berries and tropical fruits.
Preparing the Barrel for Storage
Before storing fruits in a buried barrel, ensure it’s properly prepared. Start by filling the bottom 1-2 feet with a layer of straw or sawdust to provide good airflow. This helps to regulate humidity and prevent the growth of mold. Then, add a 4-6 inch layer of gravel or small rocks to facilitate drainage.
Storing Fruits in the Barrel
When storing fruits in the buried barrel, layer them with a 1-2 inch layer of straw or sawdust between each layer. This helps to maintain good airflow and prevent fruits from coming into contact with each other. Store the fruits in a cool, dark place, ideally between 32°F and 40°F (0°C and 4°C), to slow down the ripening process.
