Learn why onions rot quickly in plastic bags. Discover how lack of air circulation and trapped moisture lead to mold and spoilage.
1 Answer
Onions rot faster in plastic bags because the bags trap moisture and prevent proper ventilation, creating a humid environment that encourages mold and bacterial growth.
Detailed Explanation:
Onions need to breathe to stay fresh. When stored in a plastic bag, the natural moisture released by the onion gets trapped. This creates a humid environment, which is ideal for the growth of mold and bacteria. These microorganisms thrive in moist conditions and accelerate the decomposition process, leading to rot. Proper ventilation allows the moisture to evaporate, keeping the onions dry and inhibiting microbial growth. Without adequate airflow, the onions essentially stew in their own moisture, significantly shortening their shelf life. The lack of air circulation also prevents the dissipation of ethylene gas, a natural plant hormone that promotes ripening and spoilage.
Pro Tip:
Store onions in a cool, dry, and well-ventilated place, such as a mesh bag or a loosely woven basket, away from potatoes. Potatoes release moisture and gases that can cause onions to spoil faster.
