How could I tell if a piece of fruit is rotten or not?

You can check the color and texture of the fruit. If it's green, brown, or shriveled up, then it might be rotten. 2 You can also smell it to see if there are any off-putting odors. 3 Finally, you can cut into the fruit and take a look at the interior to see if there are any signs of spoilage.
