How to Keep Avocado Fresh for Lunch

Depending on how you prepare your avocado for lunch, there are some ways to ensure it stays as fresh as possible for when you are ready to eat it.

Cut Avocado

If you have cut your avocado to pack for lunch, you should sprinkle the avocado pieces with some lemon or lime juice. This stops the flesh from browning. Place the cut avocado pieces in a plastic zipper bag and place it near an ice pack to keep the avocado chilled until you are ready to eat.

Whole Avocado

It is easier to keep a whole avocado fresh, compared to cut-up chunks. You should rinse the exterior of the avocado and dry it thoroughly. Place the avocado in a plastic zipper and place it in a lunch box with an ice pack to keep it chilled. Remember to include a knife in your lunch bag to use to cut the avocado.

  • Avocados tend to discolor very quickly when they are cut. To prevent sliced or cut avocado from turning brown, sprinkle a small amount of lime or lemon juice onto the flesh of the avocado, and wrap it tightly in plastic wrap.

  • Avocados can last up to 3 to 4 days in the refrigerator if stored properly, and wrapped in plastic wrap with a sprinkling of lemon juice.
  • Many people do not know that you can freeze avocado. To do this, you will need to peel and puree the avocado and add ½ tablespoon of lemon juice per avocado. The puree should be placed in a freezer bag or airtight container before being placed in the freezer.
  • Avocado stored this way in the freezer can maintain its quality for between 3 to 6 months. They can be consumed after this amount of time, but will not have the same quality.
  • Avocados that have a bad smell or appearance should be discarded.

Tricks to Keep Avocados from Turning Brown

One of the only downfalls of avocados is that they turn brown fairly quickly. This does not always affect the taste, but brown avocado is nowhere as appealing as a fresh, green slice.


Avocados turn brown due to the enzyme polyphenol oxidase, which is found under the skin. When the avocado is cut, this enzyme comes into contact with the oxygen found in the air, which turns the surface of the avocado flesh brown.

The below tricks are some of the best ways to prevent your avocados from browning too quickly.

Lemon Juice – Sprinkling some lemon or lime juice on the cut avocado is a good way to stop the surface from turning brown. The avocado will brown over time if not eaten, but the lemon or lime juice does prevent this from happening too quickly.

Plastic Wrap – Wrapping avocado in plastic wrap prevents air from reaching the surface of the flesh, which prevents browning. The top of the sliced avocado might turn slightly brown, but the flesh underneath this will still be green.

Pit – One of the easiest ways to keep an avocado from browning completely is to leave the pit in the leftover avocado half. The area that is in contact with the pit will be the last to brown, however, some of the further pieces of the avocado might turn a very light brown, but is still okay to use in a sandwich or salad.

Olive Oil – Just like plastic wrap, brushing the avocado with olive oil stops air from reaching the surface of the avocado, which encourages browning. When brushed with olive oil, the surface of the avocado might experience light browning, but the inside flesh will still be a wonderful green color.

Water – Immersing avocados in water stops the avocado flesh from being exposed to air, which helps to prevent browning. Avocado can be kept in water for up to 48 hours.

The surface of the avocado might turn slightly slimy after this amount of time, but the inside will be perfectly green, and completely fresh-tasting when eaten.

Onions – You can chop up a quarter of a red onion and place it at the bottom of a sealable container. Place the avocado skin side down on the onion.

The vapors emitted from the onion prevent the avocado from browning, but there will be no transfer of flavor between the onion and the avocado as the flesh of the avocado will not be in contact with the onion.
