What is the storage temperature for green beans

The optimal storage temperature for green beans is 8-10 degrees Celsius. Excessive temperature can easily cause the beans to rot and spoil, while low temperature may lead to cold damage. Attention should be paid to humidity control, dark storage, avoiding squeezing, and timely sorting when processing green beans.

Beans have high requirements for storage environment, and suitable low temperature can effectively delay their respiration and water loss. An environment of 8-10 degrees Celsius can maintain the freshness of green beans, and this temperature range can inhibit microbial growth without causing cell frostbite. It is recommended to use fresh-keeping bags for storage, and absorbent paper can be placed inside the bag to regulate humidity. It is ideal to maintain a relative humidity of around 90%. At the same time, avoid direct sunlight as ultraviolet radiation can accelerate the breakdown of nutrients in the beans. If the storage temperature is below 5 degrees Celsius, the surface of the beans is prone to cold damage symptoms such as dents and spots, and the cell structure is damaged, which can lead to a deterioration in taste. When the temperature exceeds 12 degrees Celsius, the beans will quickly lose water and wilt, the pods will turn yellow and age, and they are more susceptible to mold infection. Short term storage can choose the lower level of the refrigerator compartment, while long-term storage requires professional cold storage equipment. Regardless of the method used, it is necessary to regularly check and remove spoiled beans to prevent cross contamination.

When storing beans in daily life, it is recommended to first remove diseased pods and damaged parts, and retain the intact stem of the pods. You can wrap it with a clean cotton cloth first, then put it in a breathable container and store it in a cool place. Fresh beans should not be stored after cleaning, as surface moisture can accelerate spoilage. If it needs to be stored for a long time, it can be blanched and frozen, but the taste will change after thawing. Reasonable control of storage temperature can maximize the nutritional value and edible quality of soybean beans.
