Light Browning (on the surface) If the flesh of the avocado has light brown spots on the surface, it’s still safe to eat. You can simply scrape off the brown areas to reveal the green flesh underneath. This browning happens due to oxidation, which is a natural process once the avocado is exposed to air.
Dark Brown or Black Flesh If the avocado has dark brown or black flesh throughout, it may have started to spoil. While it might not be harmful to eat, the taste and texture will likely be unpleasant. It could also be a sign that the avocado is overripe.
Rancid Smell If the brown avocado smells sour or rancid, it’s best to discard it. The fruit could have gone bad, and consuming it may lead to foodborne illness.
Tips to Prevent Browning To prevent an avocado from turning brown, you can sprinkle lemon or lime juice on the exposed flesh, or store it in an airtight container with the pit still inside. Additionally, refrigerating leftover avocado can help slow the oxidation process.
Light browning on an avocado is normal and safe to eat, but dark or blackened flesh, especially if accompanied by an off-putting smell, suggests the avocado has spoiled.
Always check the texture and smell before consuming.
