If it is properly stored in a cold storage for preservation, the survival time of corn can be extended. With the continuous improvement of people's living standards, fresh corn is becoming more and more popular, which has created a market demand for fresh corn.
However, since fresh corn is prone to aging or spoiling at room temperature, how to keep it fresh is one of the main issues we need to consider. The long-term storage of fresh corn still depends on cold storage for preservation.

Next, let me tell you what characteristics we should pay attention to when storing corn in a cold storage for preservation.

Cold storage method in a preservation cold storage: Fresh corn must be refrigerated under the condition of 0 - 1℃. Fresh corn can only be stored for 1 - 2 days at normal temperature (25 - 30℃), and about half a month at 0℃.
Freeze-drying preservation method: Peel and remove the hairs from fresh corn cobs, quick-freeze them at -45℃, then vacuum dry them until the moisture content is about 10%, and then package them with polyethylene film and store them at room temperature for more than one year. According to comparison, the cost of treatment by the freeze-drying method is lower than that of the cold storage preservation method.
Quick-freezing low-temperature storage preservation method: A storage method in which fresh corn is frozen at a low temperature (-30℃ - -25℃) and then stored at a low temperature. The process is as follows: quickly put the fresh corn cobs that have been color-protected, blanched, and pre-cooled into a low-temperature quick-freezing cold storage, let them be frozen for 12 - 15 hours, and after thorough freezing, then put them into a low-temperature cold storage at -18℃ for long-term storage. This method can preserve for 5 - 6 months and still retain the aroma and flavor of fresh corn.
Storing corn in a cold storage for preservation can extend the lifespan of corn, but the taste is not as good as that of freshly picked corn. Fresh corn is delicious, but it should not be eaten too much, especially for the elderly.
