Fruit peels are the outer protective layers of fruits, serving as a barrier against pests and environmental factors. They come in various textures and colors, depending on the type of fruit. Common examples include the banana peel, orange peel, and apple skin. Peels often contain nutrients, fiber, and antioxidants, making them beneficial for health. In addition to their nutritional value, fruit peels can be used in various culinary applications. For instance, citrus peels can be zested for flavoring dishes, while apple peels can be used in making sauces or snacks. Some peels are also used in natural remedies and beauty products.
