Extended information:

Since the sugar content of sweet waxy corn drops rapidly after harvest at room temperature, it must be refrigerated at low temperature as quickly as possible. Tests have shown that at 30°C, about 60% of the soluble sugars are converted into starch one day after harvest; at 10°C, about 25% of the sugars are converted into starch in one day. Although the low temperature of 0°C has a significant inhibitory effect on the sugar conversion process, In one day, 6% of the soluble sugar is converted into starch. The loss of sugar will significantly affect the unique flavor and tender quality of fresh corn.

So fresh corn cannot be stored for a long time, let alone stored at room temperature for a long time. The suitable storage temperature for fresh corn is 0℃±0.5℃ and the relative humidity is 95-98.

Remove most of the bracts from the frozen ears of corn, leaving only a layer of inner bark, and put them into boxes lined with fresh-keeping bags. Each box is 5-7.5 kg, and they are stacked and stored. Pay attention to leaving a ventilation channel when palletizing, and keep the storage temperature constant at 0℃±0.5℃. This storage method is generally not suitable for more than 20 days.
