Pineapple is one of the delicious fruits. Pineapple fruits are compound oval fruits, usually 6 to 8 inches long with spiky, robust leaves at the top of the fruit. The tough, waxy rind is green, brown, and yellow in color with a scale-like appearance. The flesh of the pineapple is juicy and yellow to white in color.
Pineapple plants are herbaceous perennials and these plants can reach 5 feet tall and 4 feet wide. The pineapple fruit grows on a stalk in the center of the rosette of leaves. Leaves of pineapple are waxy, strap-shaped leaves 2 to 6 feet in length. They usually have a sharp point on the tip of the leaf and spines along the margins of the leaves. The leaves may be green or variegated in color.
Only if the fruit matures on the plant then Pineapple fruit quality is at its best. They do not become sweeter if harvested earlier since there are no starch reserves to be converted to sugar. The sugar content must therefore come from the rest of the plant.
Pineapples are 15% sugar along with malic and citric acids. A pineapple wine is fermented in areas near where it is grown. It is rarely seen outside of the tropics therefore it does not store well so. Pineapples also contain bromelain, a protein digesting and milk-clotting enzyme similar to pepsin. Bromelain is used commercially to tenderize meat and chill-proof beer. It is due to bromelain that people belief that pineapples are good for digestion.
