Beet Totally Explained

Everything about Beta Vulgaris totally explained

Beta vulgaris, commonly known as beet or beetroot, is a flowering plant species in the family Chenopodiaceae. Several cultivars are valued around the world as edible root vegetables, fodder (mangel) and sugar-producing sugar beet.

Description

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 very small, 3-5 mm diameter, green or tinged reddish, with five petals; they're wind-pollinated. The fruit is a cluster of hard nutlets.

Taxonomy

Three subspecies are recognised:

Beta vulgaris subsp. maritima. Sea beet. North-West Europe. Plant smaller, to 80 cm tall; root not swollen.
Beta vulgaris subsp. vulgaris. Europe. Plant larger, to 2 m tall; with a rounded fleshy taproot. The ancestor of the cultivated beets (not subsp. maritima, as sometimes stated). Var. Ruba is the red beet.
Beta vulgaris subsp. cicla - see Chard

Uses

Food

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 Africa the whole leaf blades are usually prepared with the midribs as one dish.
   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 borscht, is a popular dish. Yellow-coloured garden beets are grown on a very small scale for home consumption.
   One increasingly popular preparation involves tossing peeled and diced beets with a small amount of oil and seasoning, then roasting in the oven until tender.
   Garden beet juice is a popular health food. Betanins, obtained from the roots, are used industrially as red food colourants, for example to improve the colour of tomato paste, sauces, desserts, jams and jellies, ice cream, sweets and breakfast cereals. Hippocrates advocated the use of beet leaves as binding for wounds.
   Since Roman times, beetroot juice has been considered an aphrodisiac. It is a rich source of the mineral boron, which plays an important role in the production of human sex hormones. Field Marshal Montgomery is reputed to have exhorted his troops to 'take favours in the beetroot fields', a euphemism for visiting prostitutes.. 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'.
   Today the beetroot is still championed as a universal panacea. One of the most controversial examples is the official position of the South African Health Minister on the treatment of AIDS. Dr. Manto Tshabalala-Msimang, Health Minister under Thabo Mbeki, has been nicknamed 'Dr. Beetroot' for promoting beets and other vegetables over antiretroviral AIDS medicines, which she considers toxic.
   Research published in the American Heart Association journal Hypertension on the 4th February 2008 and showed drinking 500mls of beetroot juice a day can help reduce blood pressure levels. Researchers saw a reduction in blood pressure in volunteers after just 1 hour of drinking 500mls of beetroot juice. The reduction was more pronounced after 3 to 4 hours and up till 24 hours after drinking the juice.

Other uses

Forms with strikingly coloured, large leaves are grown as ornamentals. Nevertheless, breeding programs can produce cultivars with low geosmin levels yielding flavours more acceptable to shoppers.
Major cultivar groups include:

Fodder beet wurzel or mangold used as animal fodder.

Sugar beet grown for sugar.

Chard, a beet which has been bred for leaves instead of roots and is used as a leaf vegetable.

Beetroot or table beet (or, in the 19th century, "blood turnip") used as a root vegetable. Notable cultivars in this group include:

Albina Vereduna, a white variety.
Bull's Blood, an open-pollinated variety originally from Britain, known for its dark red foliage. It is grown principally for its leaves, which add color to salads.
Burpee's Golden, a beet with orange-red skin and yellow flesh.
Chioggia, an open-pollinated variety originally grown in Italy. The concentric rings of its red and white roots are visually striking when sliced. As a heritage variety, Chioggia is largely unimproved and has relatively high concentrations of geosmin.
Detroit Dark Red has relatively low concentrations of geosmin, and is therefore a popular commercial cultivar in the US.
India Beet isn't as sweet as Western beet.
Lutz Greenleaf, a variety with a red root and green leaves, and a reputation for maintaining its quality well in storage.
Red Ace, the principal variety of beet found in U.S. supermarkets, typical for its bright red root and red-veined green foliage.

Properties

Beta vulgaris roots contain significant amounts of vitamin C, whilst the leaves are an excellent source of vitamin A. They are also high in folate, soluble and insoluble dietary fibre and antioxidants. It is among the sweetest of vegetables, containing more sugar even than carrots or sweet corn. The content of sugar in beetroot is no more than 10%; in the sugar beet it's typically 15 to 20%.
Beetroots are rich in the nutrient betaine. Betaine supplements, manufactured as a byproduct of sugar beet processing, are prescribed to lower potentially toxic levels of homocysteine (Hcy), a homologue of the naturally occurring amino acid cysteine, which can be harmful to blood vessels thereby contributing to the development of heart disease, stroke, and peripheral vascular disease.

Red/purple colouring

The colour of red/purple beetroot is due to a variety of betalain pigments, unlike most other red plants, such as red cabbage, which contain anthocyanin pigments. The composition of different betalain pigments can vary, giving breeds of beetroot which are yellow or other colors in addition to the familiar deep red. Some of the betalains in beets are betanin, isobetanin, probetanin, and neobetanin (the red to violet ones are known collectively as betacyanin). Other pigments contained in beet are indicaxanthin and vulgaxanthins (yellow to orange pigments known as betaxanthins). Indicaxanthin has been shown as a powerful protective antioxidant for thalassemia, as well as prevents the breakdown of alpha-tocopherol (Vitamin E).
Betacyanin in beetroot may cause red urine in some people who are unable to break it down. This is called beeturia.
The pigments are contained in cell vacuoles. Beetroot cells are quite unstable and will 'leak' when cut, heated, or when in contact with air or sunlight. This is why red beetroots leave a purple stain. Leaving the skin on when cooking, however, will maintain the integrity of the cells and therefore minimise leakage.

History

Beet remains have been excavated in the Third dynasty Saqqara pyramid at Thebes, Egypt, and four charred beet fruits were found in the Neolithic site of Aartswoud in the Netherlands. But it's difficult to determine whether these are domesticated or wild forms of B. vulgaris. Zohary and Hopf note that beet is "linguistically well identified." They state the earliest written mention of the beet comes from 8th century BC Mesopotamia; the Greek Peripatetic Theophrastus later describes the beet as similar to the radish. "Roman and Jewish literary sources indicate that already in the 1st century BC domestic beet was represented in the Mediterranean basin by leafy forms (chard) and very probably also by beetroot cultivars."With the imposition of the blockade of the continent during the Napoleonic Wars there was an impetus to develop beet for their sugar content. Beet historians have long argued that the term “bonbon de naturel” or “natures candy” came into the popular vernacular during this time period.
