What is the best temperature for storing onions in cold storage?

　　The best temperature for storing onions in cold storage is generally between 0℃ and 4℃. This temperature range helps to extend the shelf life of onions, keeping them fresh and firm. Onions can slow down their metabolism at this temperature, thereby reducing water evaporation and reducing the risk of rot. In addition, this temperature range also helps to maintain the texture and taste of onions.

　　It should be noted that onions have relatively low temperature requirements, so when stored in cold storage, temperature fluctuations should be avoided as much as possible to ensure the quality and storage life of onions. At the same time, the humidity in the cold storage also needs to be controlled within the range of 65% to 70% to reduce water evaporation and rot.

　　In summary, the temperature range of 0℃ to 4℃ is the best temperature for storing onions in cold storage. Only under such temperature conditions can the shelf life of onions be maximized to ensure their freshness and quality.
