Ginger

Ginger root is used extensively as a spice in many if not most cuisines of the world. Though called a root, it is actually the rhizome of the monocotyledonous perennial plant Zingiber officinale. The active constituent of fresh ginger is gingerol, a relative of capsaicin. more...

When ginger is dried, the gingerol molecules are converted into the much more pungent shogaols. Cooking ginger transforms gingerol into zingerone, which is less pungent and has a spicy-sweet aroma.⁽¹⁾

Culinary uses

Young ginger roots are juicy and fleshy with a very mild taste. They are often pickled in vinegar or sherry as a snack or just cooked as an ingredient in many dishes. Mature ginger roots are fibrous and nearly dry. The juice from old ginger roots is extremely potent and is often used as a spice in Chinese cuisine to cover up other strong odors and flavors such as in seafood and mutton.

Ginger is also made into candy, is used as a flavoring for cookies, biscuits and cake, and is the main flavor in ginger ale, a sweet, carbonated, non-alcoholic beverage. A ginger-flavored liqueur called Canton is produced in the Guangdong province of China; it is advertised to be based on a recipe created for the rulers of the Qing Dynasty and made from six different varieties of ginger. Green ginger wine is produced in the United Kingdom traditionally Crabbie's and Stone's, in a green glass bottle.

In Japan, ginger is pickled to make beni shoga and gari or grated and used raw on tofu or noodles.

In Western cuisine, ginger is traditionally restricted to sweet foods, such as ginger ale, gingerbread, ginger snaps (a type of cookie), ginger cake and ginger biscuits.

Powdered dry ginger is used to add spiciness to gingerbread and other recipes. It tastes quite different from fresh ginger, and neither can be substituted for the other.

Ginger has a sialagogue action, stimulating the production of saliva.

Economics and distribution

Ginger is grown throughout the tropical areas of the world. The most expensive and highest quality varieties generally come from Australia, South India, and Jamaica, while most mass market ginger is grown in China.

Medicinal uses

Medical research has shown that ginger root is an effective treatment for nausea caused by motion sickness or other illness. Although very effective against all forms of nausea, PDR health officials do not recommend taking ginger root for morning sickness commonly associated with pregnancy. Ginger root also contains many antioxidants. Powdered dried ginger root is made into pills for medicinal use. Chinese women traditionally eat ginger root during pregnancy to combat morning sickness. Ginger ale and ginger beer have been recommended as "stomach settlers" for generations in countries where the beverages are made. Ginger water was commonly used to avoid heat cramps in the United States in the past.

The chacteristic odor and flavor of ginger root is caused by a mixture of zingerone, shoagoles and gingerols, volatile oils that compose about 1%–3% by weight of fresh ginger. The gingerols have analgesic, sedative, antipyretic, antibacterial, and GI tract motility effects.
