Take note that eggplants do not do well in hot or cold temperatures. You must see to it that you store them in a climate-controlled environment to preserve its freshness. See the storage techniques for eggplants listed below:

Storing eggplant at room temperature

  1. Keep the eggplant in a paper bag. Place all of your eggplants inside the paper bag as this absorbs moisture. Just wrap it loosely around your vegetable, and you do not have to tie the bag. If you are keeping the whole eggplant, don’t cut it yet if you plan to store it for days. Cutting it will only spoil your eggplants faster. Use paper towels and wrap your eggplants individually just in case you don’t have some paper bags and place them inside an unsealed plastic or vented bowl. It is not advisable to store the eggplants inside a sealed plastic bag as this will only provide poor air circulation. As a result, your eggplant will just spoil faster. 
  2. Eggplants are actually a delicate vegetable that is sensitive to both extreme hot and cold temperatures. It is best to provide your eggplants in a storage area where the temperature is between 50 and 54 °F or 10 to 12 °C. A cool, dry place like your pantry is the vegetable’s ideal storage area. Refrigerators can be too cold for them, and in the kitchen during the summer season, they may also be too hot for them. Others would suggest keeping eggplants in a dry, well-ventilated cellar, garage, or basement if your kitchen is too warm for storage.
  3. Make sure to keep your eggplants away from direct sunlight.
  4. Keep eggplants away from ethylene-producing fruits or vegetables.  Eggplants ripen faster if they are stored together with ethylene-producing produce. Ethylene is a gas that accelerates the ripening process of a fruit or vegetable. The ethylene-producing fruits involve apples, avocados, bananas, cantaloupe, kiwi, peaches, pears, peppers, and tomatoes. For ethylene-producing vegetables, they include broccoli, Brussels sprouts, cabbage, carrots, and cauliflower.

You may also store the eggplants in an open paper bag or in a perforated plastic bag. Never seal the bag or container to provide the vegetable with good airflow to hold its freshness for a longer time. 
  2. Store your eggplants in the warmest part of your fridge. Keep the eggplants in the crisper drawer of your refrigerator. The crisper drawer helps prevent moisture and controls humidity in order for any produce to last fresh for a longer time. Well, it is not wrong to store your eggplants in the refrigerator, though. However, your vegetable may not last long as it would if you put it in the crisper. The shelf door is also a warmer part of your refrigerator. You can place them there if you see it fit. 
  3. Remove ethylene-producing items stored in the crisper. As mentioned earlier, ethylene-producing fruits or vegetables can ripen your eggplants prematurely. So, you have to keep them away if you have eggplants in the crisper.
