Pineapple is an evergreen tree of Moraceae, also known as jackfruit, honey duoluo and cowherb. The fruit is huge, spherical or oval, and the heaviest can reach about 30 kilograms. The epidermis has hexagonal blunt thorns, which tend to be smooth when mature and the fruit is delicious. Known as the "queen of tropical fruits" and "fragrant teeth".
