Homemade Trick! How to Keep Avocado from Turning Black and Keep It Fresh

ADVERTISEMENT

Have you ever sliced open a perfect avocado, only to watch it turn brown minutes later? That discoloration can ruin everything from your  salad to your  guacamole. The good news? There are easy, natural ways to keep your avocados green and fresh longer — no special equipment required.

Why Do Avocados Turn Brown So Quickly?

Avocados are packed with healthy fats, fiber, and nutrients, making them a popular superfood in many parts of the world.

But they oxidize fast, turning brown when exposed to air. Thankfully, a few simple kitchen tricks can help preserve their vibrant color and creamy texture.

1. Use Red Onion as a Natural Preserver

One surprising method is to store your avocado with red onion slices. Just place a few slices in the same container, making sure they don’t touch the avocado flesh.

The onion releases sulfur compounds that act as natural antioxidants, helping slow down the browning process.

Bonus tip: Store the avocado in an airtight container with the pit still intact. This can help maintain freshness even longer.

2. Ice Water to Slow Oxidation
