What is "peel"?

The peel of a fruit refers to the outermost layer or skin that surrounds the flesh or edible portion. It serves as a protective barrier, shielding the fruit from damage, pathogens, and environmental stressors. The peel varies in thickness, texture, and color depending on the type of fruit and its maturity. Some fruit peels, such as those of oranges and lemons, are thick and tough, while others, like those of apples and grapes, are thinner and more delicate. In many fruits, the peel contains essential nutrients, antioxidants, and fiber, making it a valuable component of the fruit's nutritional profile. However, in some cases, such as with citrus fruits, the peel can be bitter or unpalatable and is often removed before consumption.
