The pineapple (Ananas comosus) is a tropical plant with an edible fruit and the most economically significant plant in the family Bromeliaceae. The pineapple is indigenous to South America, where it has been cultivated for many centuries. Since the 1820s, pineapple has been commercially grown in greenhouses and many tropical plantations. Further, it is the third most important tropical fruit in world production.
Pineapples grow as a small shrub; the individual flowers of the unpollinated plant fuse to form a multiple fruit. The plant is normally propagated from the offset produced at the top of the fruit, or from side shoot, and typically mature within a year.
Raw pineapple pulp is 86% water, 13% carbohydrates, 0.5% protein, and contains negligible fat. In a 100-gram reference amount, raw pineapple supplies 50 calories, and is a rich source of manganese (44% Daily Value, DV) and vitamin C (58% DV), but otherwise contains no micronutrients in significant amounts.
