What Are The Brown Spots In Avocado?
The brown spots in an avocado are caused by oxidation. When the avocado flesh is exposed to air, an enzyme called polyphenol oxidase reacts with oxygen, causing the brown discoloration. This process is accelerated by cutting or bruising the avocado, but it does not affect the taste or nutritional value of the fruit. However, it does reduce the visual appeal of the avocado and may signal that it is past its prime.
