(Zingiber officinale), a perennial tropical plant of the family Zingiberaceae. It is cultivated in the south of Asia. The rhizomes are fleshy, aboveground stalks up to 1 m tall, the leaves are lanceolate, the flowers are violet yellow and gathered into short, spike-shaped inflorescences. The rhizome has a pleasant aromatic odor, caused by the presence of an essential oil (1.2–3 percent in the air-dried root) and a stinging taste, dependent on the presence of the phenol-like substance, gingerol.
The dry rhizome, under the name “ginger,” is used in cooking as a condiment and is also used in the food industry for aromati-zation of certain products (jam, liqueur). According to the method of processing, two commercial varieties are distinguished: white, or Jamaica, ginger is washed, peeled, and sun-dried; black ginger is unpeeled, boiled or scalded, and sun-dried.
