PawPaw/Papaya Skin is typically thin and green when unripe, resembling that of a green banana. As the fruit ripens, the skin may develop brown spots and take on a more yellowish color, becoming softer to the touch. The texture of pawpaw skin is relatively smooth and may have a slight bumpy or wrinkled appearance. The skin is not typically consumed due to its slightly bitter taste and somewhat astringent nature.
Similarly, the skin of a papaya varies depending on the variety and level of ripeness. When unripe, the skin is usually green and can be quite smooth. As the papaya ripens, the skin transforms into shades of yellow, orange, or even reddish-orange.
Ripe carica papaya skin may develop small blemishes or dark spots, indicating its readiness to eat. The texture of papaya skin is relatively thin and may have a slightly rough or pitted surface. While the skin is generally not consumed, it is edible and contains some nutrients, although the flesh of the fruit is the main edible part.
The skin of carica papaya fruits varies in color, texture, and appearance, and while the skin of both fruits is not typically eaten, they are distinctive features that can help identify the fruits and determine their ripeness.
