Why some apples are brown inside?
This unappetizing phenomenon is actually due to a chain of biochemical reactions known as enzymatic browning. When an apple is injured (or cut into pieces), the plant tissue is exposed to oxygen. This triggers an enzyme known as polyphenol oxidase (PPO) towait for itoxidize polyphenols in the apple’s flesh.
Why are my apples rotting on the inside?
Moldy core (also known as dry core rot) begins to develop while the fruit is on the tree. It is caused by Alternaria and other species of fungi, which enter the fruit and grow in the seed cavity. Dry, spongy brown lesions extend from the core, but rotting symptoms do not develop.
