How long can beans be stored at room temperature

Beans can generally be stored for 2-3 days at room temperature, and the actual storage time is affected by factors such as temperature, humidity, maturity, damage, and storage method. Beans are perishable vegetables that are prone to spoilage at room temperature due to water loss and microbial growth. Undamaged and intact beans can be temporarily stored in a dry and ventilated environment, but may only be stored for about 1 day in high temperature and high humidity environments during summer. If there are black spots, stickiness, or odor on the surface of the beans, it indicates that they have spoiled and are not edible. If the beans are too ripe or mechanically damaged during harvesting, the rate of spoilage will significantly accelerate. These types of beans may soften and rot within 12 hours at room temperature, especially when mixed with fruits that release high amounts of ethylene.

It is recommended to put the beans in a breathable bag and place them in the refrigerator's refrigeration layer, which can extend the shelf life to 5-7 days. Before cooking, it is necessary to thoroughly clean and check for mold. Cold mixed beans must be thoroughly cooked to avoid saponin poisoning. Priority should be given to fresh green beans with full pods during daily storage to avoid excessive hoarding and waste.
