Storing vegetables in mesh bags promotes airflow, which helps to reduce moisture buildup and prevent spoilage, extending their shelf life. This also allows you to easily see the contents of the bag.
Mesh bags offer several advantages for vegetable storage compared to solid plastic bags or containers. The primary benefit is improved air circulation. Vegetables respire, meaning they release moisture and gases. When stored in a sealed environment, this moisture can lead to mold growth and accelerated decay. Mesh bags allow air to circulate around the vegetables, reducing humidity and preventing the buildup of ethylene gas, a plant hormone that speeds up ripening. This helps keep vegetables fresher for longer. Furthermore, the visibility offered by mesh bags allows you to quickly identify what you have on hand, reducing food waste by ensuring you use vegetables before they spoil. Different mesh sizes can also be used for different vegetables; larger mesh for heartier vegetables like potatoes and onions, and finer mesh for more delicate greens.
Avoid storing mesh bags of vegetables near fruits like apples and bananas, as these fruits release high levels of ethylene gas, which can cause your vegetables to ripen and spoil faster, even with the airflow provided by the mesh.
