Onions have are relatively longer storage life. Freshly raw onions may be stored in the pantry for 2–3 weeks, perhaps even longer, if done carefully. This all varies based on how they’re being stored. If you store them for an extended amount of time but rarely use them, it’s a good idea to check on them once a week. Pick the ones that are rotten or are about to go rotten and throw them away so that others don’t take up the virus.

Onions, whether halved or cut into small pieces, also stay for a long time. Generally select fresh, solid onions that are free of sprouts. The onions aren’t newly picked if they have green stems growing on them. Examine the area for brownish, dark, or squishy areas. Onions with bruising or dark stains have a higher chance of spoiling.

If you preserve an onion for an extended time, you may need to remove just a few dry skins until getting to the good part. You may come across a brownish and often sticky layer in the center periodically. That is unusual but not uncommon, but all you do to be safe is to eliminate that piece.

It normally takes 40 – 60 days for all of them to be suitable for the conservation and long shipping. It can then be traded or eaten after this method.

Onion storage is very identical to pepper or bulb storage. Air temperature, moisture, and airflow are the three aspects to consider.

  • For the first, a chilly temperature is desirable, thus, a closet or a dark cupboard in the kitchen far out from the stove would suffice. To address the second problem, ensure that the area is dried even if there are no forms of moisture nearby.
  • Ensure the bag in which the onions are stored allows for unrestricted ventilation. If it’s a sealable bag, poke a few holes in it and keep the top intact. Alternatively, move the vegetables to a dish or carton without a covering.

Storing onions in a plastic shopping bag isn’t a smart idea. Avoid stacking many slices of onions over top of one another. Air must be allowed to circulate freely for the onions to remain dried by being in storage.

After you’ve sliced or diced the onions, place them in the refrigerator. Place them in a bag in the freezer or a sealed container to keep them fresh. The vegetables will not draw any more moisture from the outdoors, will not be dried out, and their odor will be retained within the container.
