We're marvelling at the wonderful properties of beets, of course.
The beet (Beta vulgaris) is a plant in the Chenopodiaceae family which is now included in Amaranthaceae family.[1][2][3][4][5] It is best known in its numerous cultivated varieties, the most well known of which is the purple root vegetable known as the beetroot or garden beet. However, other cultivated varieties include the leaf vegetables chard and spinach beet, as well as the root vegetables sugar beet, which is important in the production of table sugar, and mangelwurzel, which is a fodder crop. Three subspecies are typically recognised. All cultivated varieties fall into the subspecies Beta vulgaris subsp. vulgaris, while Beta vulgaris subsp. maritima, commonly known as the sea beet, is the wild ancestor of these, and is found throughout the Mediterranean, the Atlantic coast of Europe, the Near East, and India. A second wild subspecies, Beta vulgaris subsp. adanensis, occurs from Greece to Syria.
The beet has a long history of cultivation stretching back to the second millennium BC. The plant was probably domesticated somewhere along the Mediterranean, whence it was later spread to Babylonia by the 8th century BC and as far east as China by 850 AD. Available evidence, such as that provided by Aristotle and Theophrastus, suggests the leafy varieties of the beet were grown primarily for most of its history, though these lost much of their popularity much later following the introduction of spinach. The beet became highly commercially important in 19th century Europe following the development of the sugar beet in Germany and the discovery that sucrose could be extracted from them, providing an alternative to tropical sugar cane. It remains a widely cultivated commercial crop for producing table sugar.
Beta vulgaris is a herbaceous biennial or, rarely, perennial plant with leafy stems growing to 1–2 m tall. The leaves are heart-shaped, 5–20 cm long on wild plants (often much larger in cultivated plants). The flowers are produced in dense spikes; each flower is very small, 3–5 mm diameter, green or tinged reddish, with five petals; they are wind pollinated. The fruit is a cluster of hard nutlets.
Spinach beet leaves are eaten as a pot herb. Young leaves of the garden beet are sometimes used similarly. The midribs of Swiss chard are eaten boiled while the whole leaf blades are eaten as spinach beet.
In some parts of Africa, the whole leaf blades are usually prepared with the midribs as one dish.[7]
The leaves and stems of young plants are steamed briefly and eaten as a vegetable; older leaves and stems are stir-fried and have a flavour resembling taro leaves.
The usually deep-red roots of garden beet are eaten boiled either as a cooked vegetable, or cold as a salad after cooking and adding oil and vinegar. A large proportion of the commercial production is processed into boiled and sterilised beets or into pickles. In Eastern Europe beet soup, such as cold borsch, is a popular dish. Yellow-coloured garden beets are grown on a very small scale for home consumption.[7]
Beetroot can be peeled, steamed, and then eaten warm with butter as a delicacy; cooked, pickled, and then eaten cold as a condiment; or peeled, shredded raw, and then eaten as a salad. Pickled beets are a traditional food of the American South. It is also common in Australia and New Zealand for pickled beetroot to be served on a hamburger.[8]
A traditional Pennsylvania Dutch dish is red beet eggs. Hard-boiled eggs are refrigerated in the liquid left over from pickling beets and allowed to marinate until the eggs turn a deep pink-red color.
In Poland, beet is combined with horseradish to form popular Ćwikła z chrzanem, which is often added to a meal consisting of meat, potatoes and a salad.
When beet juice is used, it is most stable in foods with a low water activity, such as frozen novelties and fruit fillings.[9] Betanins, obtained from the roots, are used industrially as red food colourants, e.g. to intensify the colour of tomato paste, sauces, desserts, jams and jellies, ice cream, sweets and breakfast cereals.[7]
Beet pulp is fed to horses that are in vigorous training or conditioning and to those that may be allergic to dust from hay.[citation needed]
Beetroot can also be used to make wine.[10]
The consumption of beets causes pink urine in some people.
Jews traditionally eat beet on Rosh Hashana (New Year). Its Aramaic name סלקא sounds like the word for "remove" or "depart"; it is eaten with a prayer "that our enemies be removed".[11]
Beetroot juice has been found to improve performance in athletes, possibly because of its abundance of nitrites. [12]
The roots and leaves of the beet have been used in folk medicine to treat a wide variety of ailments.[7] Ancient Romans used beetroot as a treatment for fevers and constipation, amongst other ailments. Apicius in De re coquinaria gives five recipes for soups to be given as a laxative, three of which feature the root of beet.[13] Hippocrates advocated the use of beet leaves as binding for wounds. Since Roman times, beetroot juice has been considered an aphrodisiac. From the Middle Ages, beetroot was used as a treatment for a variety of conditions, especially illnesses relating to digestion and the blood. Platina recommended taking beetroot with garlic to nullify the effects of 'garlic-breath'.[14][clarification needed]
It has been suggested the pigment molecule betanin in the root of red beets may protect against oxidative stress and has been used for this purpose in Europe for centuries.[15]
All parts of the beet plant contain oxalic acid. Beet greens and Swiss chard are both considered high oxalate foods which have been implicated on the formation of kidney stones.
[edit]Other uses
Cultivars with large, brightly coloured leaves are grown for decorative purposes.[7]
Beets are used as a food plant by the larvae of a number of Lepidoptera species.
The sea beet, the ancestor of modern cultivated beets, prospered along the coast of the Mediterranean Sea. Beetroot remains have been excavated in the Third dynasty Saqqara pyramid at Thebes, Egypt, and four charred beetroots were found in the Neolithic site of Aartswoud in the Netherlands though it is difficult to determine whether these are domesticated or wild forms of B. vulgaris. Zohary and Hopf note that beetroot is "linguistically well identified." They state the earliest written mention of the beet comes from 8th century BC Mesopotamia.[22] The Greek Peripatetic Theophrastus later describes the beet as similar to the radish, while Aristotle also mentions the plant.[22][23] Roman and Jewish literary sources suggest that by the 1st century BC the domestic beet was represented in the Mediterranean basin primarily by leafy forms like chard and spinach beet.[22] Zohary and Hopf also argue that it is very probable that beetroot cultivars were also grown at the time, and some Roman recipes support this.[22][23] Later English and German sources show that beetroots were commonly cultivated in Medieval Europe.[23]
[edit]Rise of the sugar beet
Modern sugar beets date back to mid-18th century Silesia where the king of Prussia subsidised experiments aimed at processes for sugar extraction.[23][24] In 1747 Andreas Marggraf isolated sugar from beetroots and found them at concentrations of 1.3-1.6%.[6] He also demonstrated that sugar could be extracted from beets that was the same as that produced from sugarcane.[24] His student, Achard, evaluated 23 varieties of mangelwurzel for sugar content and selected a local race from Halberstadt in modern-day Saxony-Anhalt, Germany. A man named Koppy and his son further selected from this race for white, conical tubers.[6] The selection was named 'Weiße Schlesische Zuckerrübe', meaning white Silesian sugar beet, and boasted about a 6% sugar content.[6][23] This selection is the progenitor of all modern sugar beets.[6]
A royal decree led to the first factory devoted to sugar extraction from beetroots being opened in Kunern, Silesia (now Konary, Poland) in 1801. The Silesian sugar beet was soon introduced to France where Napoleon opened schools specifically for studying the plant. He also ordered that 28,000 hectares (69,200 acres) be devoted to growing the new sugar beet.[23] This was in response to British blockades of cane sugar during the Napoleonic Wars, which ultimately stimulated the rapid growth of a European sugarbeet industry.[23][24] By 1840 about 5% of the world's sugar was derived from sugar beets, and by 1880 this number had risen more than tenfold to over 50%.[23] The sugar beet was introduced to North America after 1830 with the first commercial production starting in 1879 at a farm in Alvarado, California.[6][24] The sugar beet was also introduced to Chile via German settlers around 1850.[6]
