You can use olive oil, lemon juice, lime juice, or sour cream to prevent leftover avocados from browning, but avocado oil is the easiest and most efficient way.

To keep your avocados fresh with avocado oil, coat a kitchen brush in the oil, spread it on the exposed fruit flesh, and store the avocado in a sealed plastic bag or container.

The oil creates a protective layer between the fruit and the air, preventing the flesh from oxidizing and turning brown.

Unlike other avocado storage hacks, like lime juice, sour cream, or even olive oil, avocado oil works best because it won’t alter the flavor of the fruit itself.
