Immediate use vs storage

Sometimes, you may only need a portion of chopped onion for a particular dish. If you expect to use leftover onions within a day or two, it’s usually safe to store them in the refrigerator. However, for longer storage, it is best to use one of the short-term or long-term storage methods described below.

Airtight containers: Use airtight containers to store sliced onions in the refrigerator.

One of the most effective short-term storage methods is to store chopped onions in an airtight container. Airtight containers prevent air from reaching the onion, slowing the oxidation process that leads to spoilage. Before sealing the container, make sure the onions are as dry as possible to minimize moisture and mold formation.

Wrapping in plastic wrap: Wrap chopped onions properly to minimize exposure to air.

Another option is to wrap the chopped onion tightly in plastic wrap or aluminum foil. Wrapping onions prevents air from reaching the cut surfaces, increasing their freshness. Remember to remove any excess air from the wrapping to create a snug enclosure.

Ziplock Bags: Using reusable plastic bags as an alternative storage method.

If you don’t have airtight containers or plastic wrap, reusable plastic bags can serve as a convenient alternative. Place the chopped onion in the bag and press out any excess air before sealing it. Ziplock bags provide a tight seal, preserving onion quality for a short period of time.

Cold Water Soak: An effective short-term storage hack to prevent onion odor.

If you plan to use chopped onions within a few hours and want to reduce their pungent smell, try soaking them in cold water. Place the chopped onion in a bowl of cold water and place the bowl in the refrigerator. This technique can help reduce onion odor emissions while keeping them fresh.

III. How to preserve cut onions without refrigerator

Preserving cut onions without a refrigerator can be challenging because onions are prone to spoilage when exposed to air and moisture. However, there are a few methods you can try to extend their shelf life:

1. Sealing in an Airtight Container: Place the cut onions in an airtight container or a resealable plastic bag, removing as much air as possible before sealing. This will help prevent moisture from reaching the onions and slow down their deterioration. You can also wrap them tightly in plastic wrap before placing them in the container.
2. Use a Paper Towel: Put a paper towel in the container with the cut onions. The paper towel can help absorb excess moisture, which can reduce the chances of mold and spoilage.
3. Store in a Cool, Dry Place: Find a cool, dry place in your kitchen to store the container with the cut onions. Keep them away from direct sunlight and heat sources, as heat can accelerate spoilage.
4. Use a Zip-Top Bag with a Straw: Place the cut onions in a zip-top bag and seal it almost completely, leaving a small opening. Insert a straw into the opening and suck out as much air as possible before sealing the bag completely. This will create a vacuum seal and minimize the exposure to air.
5. Dry the Onions: If you have the time and patience, you can try drying the cut onions. Lay them out on a tray or a baking sheet and let them air dry for a few hours or overnight. Once they are completely dry, store them in an airtight container in a cool, dark place. Dried onions can be rehydrated when you’re ready to use them.
6. Use Preservatives: Some people use lemon juice or vinegar to preserve cut onions. The acidity can help slow down spoilage. Toss the cut onions in a little lemon juice or vinegar before storing them in an airtight container.

Keep in mind that even with these methods, cut onions won’t last as long as they would in the refrigerator. They may still start to deteriorate after a day or two. Therefore, it’s best to use them as soon as possible if you don’t have access to a refrigerator.

How to keep cut onions odor free

Once you have learnt how to store cut onion, it is also imperative for you to keep them odor free. 

Understanding the science behind onion odor

The strong and distinctive odor of onions is due to sulfur-containing compounds that are released when onion cells are damaged. When you chop an onion, enzymes react with these sulfur compounds, creating volatile compounds that evaporate into the air and produce a distinctive smell. Understanding this chemical process can help you take specific steps to reduce and control onion odor in your kitchen.

Tips for preventing onion odors from spreading in the kitchen and refrigerator.

Consider the following tips to prevent onion odors from spreading throughout your kitchen and fridge:

1. Adequate ventilation: Ensure good ventilation in your kitchen by opening exhaust fans or windows while chopping onions. This helps to get rid of onion smell quickly.
2. Isolate onions: Store chopped onions in a separate airtight container or wrap them securely to prevent odors from entering other foods in the refrigerator.
3. Baking Soda: Keep an open container of baking soda near the bite area or in the refrigerator to absorb and neutralize odors.
4. Activated charcoal: Like baking soda, activated charcoal is great for absorbing and eliminating odors. Keep a few pieces of activated charcoal in the kitchen or fridge to prevent onion odor.
5. Lemon juice: Rub your hands with lemon juice after chopping onions to help remove the smell of onions.

Use of odor absorbents to neutralize onion odor.

In addition to baking soda and activated charcoal, other odor absorbents can be effective in neutralizing onion odors. Some options include coffee grounds, vinegar, or even a few drops of an essential oil such as lemon or peppermint in a bowl. Strategically placing these substances around the kitchen can help maintain a fresh-smelling environment.
