Avocados have earned a reputation for being temperamental, especially with the ripening process.

Even once they do ripen, they don’t stay price for long, turning brown and mushy.

Karl Graham, a food storage expert at Click Storage, has unveiled how to “double” an avocado’s lifespan.

The simple process uses scientific reactions to preserve the inside of the popular fruit.

The expert said: “Only a few materials are needed to extend its life and continue enjoying this delicious fruit, all while absorbing its healthy benefits.”

1. Wait for ripeness

Allow avocados to ripen on the counter at room temperature.

If the stem of the avocado can be easily removed from the top of the avocado and the flesh underneath is green, it’s ripe.

2. Apply citrus juice

Once ripe, cut the avocados in half and lightly brush the flesh of the avocado with lime or lemon juice.

The expert said: “Storing them with lime juice has become popular despite their rising costs and temperamental ripening process.

“The acidity in lime juice helps to slow down this enzyme, keeping the avocados vibrant, green and fresher for longer.

“This is particularly beneficial for those who like to meal prep or stock up on avocados for the week.” 

3. Store in an airtight container

Place the lime or lemon juice-coated avocado halves in an airtight container.

If only using half an avocado, store the half that still has the seed in it to help preserve the avocado further.

The expert noted: “If the avocados are not cut, brush some lime or lemon juice on the exterior to help keep it ripe for even longer while in the airtight container."

4. Refrigerate

Put the container in the refrigerator as cold temperatures will slow down avocado ripening.

Karl said: “When exposed to cold temperatures, the enzymes responsible for ripening slow down, thus prolonging the shelf life of the avocado.”
