Raw beetroot is 88% water, 10% carbohydrates, 2% protein, and less than 1% fat (see table). In a 100-gram ( 3 + 1 ⁄ 2 -ounce) amount providing 180 kilojoules (43 kilocalories) of food energy , raw beetroot is a rich source (27% of the Daily Value (DV)) of folate and a moderate source (16% DV) of manganese , with other nutrients having ...
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 minimize leakage.
The most heavily studied betalain is betanin, also called beetroot red after the fact that it may be extracted from red beet roots. Betanin is a glucoside, and hydrolyzes into the sugar glucose and betanidin. [2]
Beet (Beta vulgaris) has an immense economic importance as sugar crop , and a great importance as a vegetable (Chard, Beetroot), and as fodder plant (Mangelwurzel). This species is also used as medicinal plant, ornamental plant, dye and as renewable resource.
The species beet consists of several cultivar groups. The 16th-century French scientist Olivier de Serres discovered a process for preparing sugar syrup from (red) beetroot. He wrote: "The beet-root, when being boiled, yields a juice similar to syrup of sugar, which is beautiful to look at on account of its vermilion colour" [11] (1575). [12]
Because the level of circulatory glucose is largely determined by the intake of dietary carbohydrates, diet controls major aspects of metabolism via insulin. [18] In humans, insulin is made by beta cells in the pancreas, fat is stored in adipose tissue cells, and glycogen is both stored and released as needed by liver cells. Regardless of ...
