What Actually Are The Brown Spots on Fruits and Vegetables

You have certainly noticed that most apples, pears or potatoes are prone to small brown spots on peels. Have you ever wondered what these are? The small spots, no bigger than a needle prick, are called lenticules and are very important. Today you will find out more information about these small brown spots.

What is their role? Just like humans, vegetables and fruits need fresh air. Fresh air for fruits and vegetables means carbon dioxide. Flowers, trees, plants, all inspire carbon dioxide and exhale oxygen. But, unlike humans, they have no nostrils, they have lenticules.

Through these small holes, plants and vegetables absorb carbon dioxide and eliminate oxygen.

Like any open pore, lenticels are prone to disease and infection. The most common diseases is the breakdown of lenticel, which occurs due to a nutrient deficiency and forms those brown spots on the fruit peel. These spots do not affect the inside of the fruit, but it makes the apple, for example, no longer look so appealing on the outside.

The breakdown of lenticel also affects the texture of the fruit or vegetables. The spots will get a rough and uneven appearance, like a weird rash.
