Storing Whole Unripe Avocados
Unripe, not-yet-ready-to-eat avocados should be stored at room temperature to speed up the ripening process. Leave them on the countertop, out of direct sunlight. Ripening could take up to five days, but be sure to check their ripeness daily by gently pressing on them to see if they yield to pressure.
How to Store Cut Avocados
Once you cut into an avocado, it has been exposed to its worst enemy: oxygen. Avocado flesh turns brown when opened to the air because of a reactive enzyme, a process otherwise known as oxidation. Trying to keep a cut half of an avocado ripe is an uphill battle. But there are some preventative measures you can take to protect that beautiful green flesh from turning brown and unappetizing.
Storing Ripe Avocado Halves
Fresh and ready avocado halves are a sight to behold. But they won't stay that way for long. To keep them from turning brown, seal the flesh with a sprinkle of lemon juice, lime juice, or olive oil, then tightly wrap it in plastic wrap and refrigerate.
You can also protect the avocado flesh with water. Fill a container with water and place the avocado half flesh-side-down in the water. Cover and place in the refrigerator for up to two days.
Storing Unripe Avocado Halves
While a ripe avocado half is a beautiful thing, there's nothing worse than cutting into an avocado only to find the flesh firm and inedible. But before you toss it, try these tips. Sprinkle the flesh with lemon or lime juice, place the halves back together, and wrap with plastic wrap. Stick it in the fridge and check its ripeness each day.
With these preservatives measures, avocados can be stored for a long time, which reduces the spoilage rate.
