Eggplants are not a Good Candidate for Storage in the Refrigerator.
The eggplant is a delectable and fragile vegetable that can deteriorate when subjected to additional light, dampness, or heat. Keeping it in the refrigerator for an extended period of time may result in mush, mold, or other unappetizing issues.
The maximum amount of time that eggplants can be kept at room temperature is five days. If you want it to last a few more days, put it in the refrigerator. The final step is to wrap the item in a paper towel; if you don’t, the condensation will quickly degrade it.
