Avocados are a delicious and nutritious addition to any meal, but their tendency to turn brown quickly after being cut can be frustrating. Fortunately, there are several methods to keep your avocado looking fresh and appetizing. One popular solution involves using lemon juice, but how effective is it? In this article, we’ll dive into whether lemon juice can stop avocados from browning, along with other helpful tips and tricks.
Why Do Avocados Turn Brown?
Before we explore the magic of lemon juice, it’s essential to understand why avocados turn brown in the first place. Avocados contain an enzyme called polyphenol oxidase, which reacts with oxygen in the air. This reaction, known as oxidation, causes the flesh of the avocado to change color, resulting in an unappealing brown hue. While a browned avocado is still safe to eat, its taste and appearance can be less than desirable.
The Power of Lemon Juice
Lemon juice contains ascorbic acid, also known as vitamin C, which acts as a natural antioxidant. When applied to the surface of a cut avocado, the ascorbic acid creates a barrier that reduces oxidation. The acid in the lemon juice lowers the pH level of the avocado and decreases enzyme activity, slowing down the browning process.
How to Use Lemon Juice to Keep Avocado Green
- Cut the Avocado: Slice your avocado as usual, removing the pit if desired.
- Apply Lemon Juice: Squeeze or brush a generous amount of fresh lemon juice over the exposed surface of the avocado. Ensure that all areas are coated evenly.
- Store Properly: Place the avocado in an airtight container and store it in the refrigerator.
Additional Tips
- Chef Betsy Wiegand recommends storing the avocado completely covered to further reduce oxygen exposure.
- Jessica Gavin recommends adding one tablespoon of lemon juice to four cups of cold water and soaking the cut avocados for no longer than 10 minutes.
Other Methods to Prevent Avocado Browning
While lemon juice is a popular and effective method, several other techniques can also help keep your avocado from turning brown.
1. Olive Oil
Brushing a thin layer of olive oil over the exposed surface can shield the avocado from oxygen. This method works for about a day.
2. Plastic Wrap
Tightly wrap the surface of the avocado with cling wrap, ensuring minimal air gaps. For guacamole, gently press the cling wrap down onto the surface to remove all air pockets.
3. Water Submersion
Submerge the avocado in water, open-side down, in a container in the refrigerator. While effective, the FDA doesn’t recommend this method because the water can serve as a breeding ground for harmful pathogens.
4. Onion
Store the avocado open-side up over a few pieces of sliced onion in an airtight container. The sulfur compounds released by the onion act as a natural preservative.
