Can you store avocado with lemon juice to prevent browning?

Question

Yes! Learn how to use lemon juice to prevent avocado browning. It's a classic trick that helps keep your cut avocados fresh and green.

Answer 1

Yes, you can store avocado with lemon juice to prevent browning. The citric acid in lemon juice slows down oxidation, which causes the avocado to turn brown.

Detailed Explanation:

Avocados turn brown due to a process called enzymatic browning. When the flesh of an avocado is exposed to air, an enzyme called polyphenol oxidase (PPO) reacts with phenolic compounds in the avocado. This reaction, in the presence of oxygen, produces melanins, which are brown pigments.

Lemon juice contains citric acid, which is a natural antioxidant. Antioxidants work by slowing down or preventing oxidation. When you apply lemon juice to the surface of an avocado, the citric acid inhibits the activity of the PPO enzyme, thus slowing down the browning process.

To effectively prevent browning, make sure to coat all exposed surfaces of the avocado with lemon juice. You can also use lime juice, which contains similar acids. For cut avocados, press plastic wrap directly onto the surface of the avocado flesh after applying lemon juice to minimize air exposure.

Pro Tip:

For guacamole, adding a layer of water or milk on top before refrigerating can further minimize browning by creating a barrier against air. Pour a thin layer, about 1/2 inch, and then drain it off before serving.
