How to keep avocado from turning brown?

There are various tricks that you can use to prevent avocados from turning brown and these include pairing them with some sliced onions, brushing them with some lemon, brushing the flesh with some olive oil, sealing them with a plastic wrap and submerging them in water. We will look at the tricks in depth shortly.

But first, let’s find out why avocados brown.

Why do avocados brown?

The browning of avocados is a chemical reaction process as a result of its exposure to the oxygen present in the air. This tends to be accelerated by the presence of compounds in the avocados known as phenolic compounds.

When the flesh of the avocado is exposed to oxygen after being sliced, an enzyme known as polyphenol oxidase in the avocados assists in the conversion of the phenolic compounds to another class that is known as quinones.

The quinones then polymerize and form these long chains of polyphenols known as polyphenols. It is this polymerization process that exhibits itself as the brown discoloration of the flesh.  The browning process is not only unique to avocados it also occurs to fruits such as apples.

How do you prevent avocados from browning?

They are various tricks that you can use to prevent your avocados from browning. Some of them are:

Pairing your avocados with sliced onions

You can dice up about a quarter of a red onion and put it in the bottom of a sealable container. Then proceed to place the fleshy side of the avocado on the onions. Onions usually have sulfur compounds that reduce the rate of oxidation.

Brush the avocados with some olive oil

The key here is to prevent oxygen from getting in contact with the flesh of the avocado which sets off a chain of reaction that leads to oxidation. Brushing the flesh of the avocado with olive oil creates a barrier that prevents oxidation.

After brushing the flesh with some olive oil or any vegetable oil for that matter ensure that you seal the avocado in an airtight container. This should be able to prevent enzymatic browning for about a day or so.

Seal the avocados with a plastic wrap/cling

Once again, the goal here is to create a barrier to oxygen. To do this, carefully wrap a plastic lining against the fleshy part of the avocado. You can choose to remove the pit or just leave it, however if you take it out ensure that the plastic wrap presses along the sunken section of the pit to form a tight seal.

Brush with some lemon

Another way of preventing browning of avocados is by rubbing some lemon juice on the exposed flesh of the avocado. The enzymes that accelerate enzymatic browning don’t function optimally under acidic conditions and this will therefore delay the browning process for a day or so.

Submerge your avocados in water

You can as well submerge your avocados in water as a whole. Thereafter you can place them in the refrigerator. This will assist in keeping them fresh incase you happen to have many of them to consume quickly or are traveling for a while.

Leave the seed pit in the avocado

This is perhaps the most known method. However, leaving the seed pit in the avocado only curbs enzymatic browning on the part that is protected from the oxygen. All the other exposed parts of the avocado flesh will end up turning brown in time.
