Why does guacamole turn brown?
Before we dive into the preservation techniques, let’s first understand why guacamole turns brown. When oxygen reacts with the enzymes in the avocado, it causes a process called oxidation, which turns the exposed surface of the guacamole brown. Thankfully, there are several methods to slow down or prevent this oxidation process.
Best ways to preserve guacamole
Here are some tried and tested methods to ensure your guacamole stays fresh and green:
-
1. Use plastic wrap directly on the guacamole
Pressing a layer of plastic wrap directly onto the surface of the guacamole helps to minimize its contact with air, thus preventing oxidation. Make sure to push out as much air as possible before sealing the container.
-
2. Add lemon or lime juice
Lemon or lime juice contains citric acid, which acts as a natural preservative. Adding a squeeze of fresh lemon or lime juice to your guacamole can help delay the browning process, keeping it fresh for longer.
-
3. Store in an airtight container
When it comes to preserving guacamole, keeping it airtight is key. Invest in a good quality airtight container to store your guacamole. This prevents unnecessary exposure to air, helping it retain its vibrant green color.
-
4. Store with an avocado pit
Believe it or not, placing the avocado pit in the middle of your guacamole can help keep it fresh. The pit acts as a natural inhibitor of oxidation, helping to maintain the green color of your guacamole.

5. Freezing guacamole
If you have a large batch of guacamole that you want to preserve, freezing is your best option. Scoop the guacamole into an airtight container, leaving some space at the top for expansion during freezing. When you’re ready to enjoy it, simply thaw it in the refrigerator and give it a good stir.
Preserving guacamole is all about minimizing its exposure to air and using natural preservatives. By following these tips and tricks, you can extend the longevity of your guacamole and enjoy it for days to come. Whether you choose to use plastic wrap, lemon juice, store in an airtight container, or even freeze it, these preservation methods will ensure you always have fresh and delicious guacamole ready to be enjoyed.
Remember, the key is to experiment and find the method that works best for you. So, the next time you make a batch of guacamole, put these preservation techniques to the test and savor the taste of your preserved guacamole!
