Can placing an avocado seed in guacamole prevent discolouration? ›

Some people swear by this one, so we had to put it to the test. The verdict: Contrary to popular belief, adding the avocado pit to guacamole does not prevent oxidation. In fact, if it sticks out above the surface, it creates air pockets that prevent the plastic wrap from adhering tightly enough.

Some of the ways in which you could easily block the enzyme's activity and prevent avocado browning are by wrapping it thoroughly, adding lemon or pineapple juice, or storing it with an onion. While avocados are safe to eat after they've turned brown, their quality may be reduced.

Pour a thin but visible layer of water or lemon/lime juice over the guacamole to form a barrier with the air. Cover the dish with plastic wrap, pushing the wrap, so it is flush with the guacamole to prevent air pockets, or put the guacamole in a sealed tub.

Many aficionados promote a time-tested approach to this problem: adding the whole avocado pit to the guacamole to help stanch the browning. Science actually supports this method, but not for the reasons you might expect.

My daughter has been asking to take this to school in her lunch and so I ended up packing it a few times. It turns out that the apple cider vinegar keeps it from turning too brown in her lunchbox. Bonus!

“Each panned guac gets sealed airtight with Saran Wrap,” he said. “Then it gets lidded, labeled and stored for later use. This process ensures freshness and prevents browning,” he continued.

Although brown guacamole isn't the most appealing, it's completely safe to eat (as long as you've stored the guacamole in the refrigerator, and it isn't more than three days old). "While a bit off-putting to look at, brown guacamole is totally safe," confirms Food Network's nutritionist, Dana Angelo White, MS RD ATC.

You see, lime is a very strong acidic flavor and it can easily overpower the delicate flavor of the avocado. Instead, finely dice red onions and pickle them with lime juice for 15-30 minutes.

Make your guacamole, then place any uneaten dip in a resealable container. Place a piece of plastic wrap on the surface of the dip, lightly pressing all over to make sure the plastic is directly in contact with the entire surface of the dip. Store the guacamole in the refrigerator for up to 2 days.

I simply squeezed the juice from half a lemon over the surface of the prepared guacamole. I checked for browning after one hour, one-and-a-half hours, and two hours.

Does olive oil prevent guacamole from turning brown? ›

Olive Oil

Rather than reacting with the browning enzyme, a thin layer of olive oil acts can act as a barrier between the dip and the air. If oxygen never reaches your guacamole, it can't turn brown. Use how ever much you need to coat the surface of the guac.

Some people swear by this one, so we had to put it to the test. The verdict: Contrary to popular belief, adding the avocado pit to guacamole does not prevent oxidation. In fact, if it sticks out above the surface, it creates air pockets that prevent the plastic wrap from adhering tightly enough.

You might have seen someone store their guacamole with the avocado's pit still in the bowl in the hopes it would keep the dip from browning.

Once opened, store-bought guacamole usually lasts 1-2 days. Homemade guacamole also usually lasts 1-2 days. You'll know it's gone bad when it has a substantial puddle of brown liquid and the layers below the surface have lost their vibrant green hue. That's when it's time to throw it out.

It's best to refrigerate an avocado that is ripe or close to it. If you refrigerate an unripe avocado, it will ripen eventually, but the texture and taste may be compromised. If your avocado is ripe, place the whole, uncut avocado in an airtight container or in the produce drawer in the refrigerator.

An even easier method is to submerge your ripe avocado in water. Cut your avocado in half and fill a glass or plastic container near full with water. With the flesh-side down, place the avocado in the container, cover, and place in the fridge. This will keep the avocado from turning brown for about another two days.

The method seemed simple enough: You're supposed to submerge whole avocados in cool water in an airtight container and place it in the refrigerator. Leave the container there until you're ready to use. Take it out, dry off the avocados, and enjoy.
