Can you use brown lemons?
Also to know is, can you eat brown Lemons?
Brown flesh on the inside of a lemon indicates a problem with the fruit. Most people who know their way around the kitchen know lemon juice can be used to keep foods like apples and avocados from turning brown when their flesh is exposed to oxygen. What may not be known is why the flesh of a lemon turns brown.
Likewise, are brown Lemons bad?
Just like it does with limes. A whole lemon should last about a week on the countertop, and a few days longer in the pantry. When it comes to cut lemons, they retain quality for about 3 to 4 days in the fridge. They won't go bad after that period, but they will inevitably shrivel and dry out.
Alternaria fruit rot affects the fruit of lemon trees, changing the color prematurely and causing a soft rot. Early infection of fruit results in sunken dark brown to black spots surrounded by a yellow halo. Infected fruit will have a brown to black discoloration inside.
