Turnip (brassica Rapa)
The turnip or white turnip (''Brassica rapa'' subsp. ''rapa'') is a root vegetable commonly grown in temperate climates worldwide for its white, fleshy taproot. The word ''turnip'' is a compound of ''turn'' as in turned/rounded on a lathe and ''neep'', derived from Latin ''napus'', the word for the plant. Small, tender varieties are grown for human consumption, while larger varieties are grown as feed for livestock. In Northern England, Scotland, Ireland, Cornwall and parts of Canada (Quebec, Newfoundland, Manitoba and the Maritimes), the word ''turnip'' (or ''neep'') often refers to rutabaga, also known as ''swede'', a larger, yellow root vegetable in the same genus (''Brassica''). Description The most common type of turnip is mostly white-skinned apart from the upper , which protrude above the ground and are purple or red or greenish where the sun has hit. This above-ground part develops from stem tissue, but is fused with the root. The interior flesh is entirely white. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rapini
Rapini or broccoli rabe () is a green cruciferous vegetables, cruciferous vegetable, with the leaves, buds, and stems all being edible; the buds somewhat resemble broccoli, but do not form a large head. Rapini is known for its bitter taste, and is particularly associated with Mediterranean cuisine. Classification Native to Europe, the plant is a member of the tribe Brassiceae of the Brassicaceae, Brassicaceae (mustard family). Rapini is classified scientifically as ''Brassica rapa'' var. ''ruvo''. It is also known as broccoletti, broccoli raab, broccoli rabe, spring raab, and ruvo kale. Turnip and bok choy are different varieties (or subspecies) of this species. Description Rapini has many spiked leaves that surround clusters of green buds that resemble small heads of broccoli. Small, edible yellow flowers may be blooming among the buds. Rapini is a source of vitamins vitamin A, A, vitamin C, C, and Vitamin K, K, as well as Potassium in biology, potassium, Calcium in biolo ...

Daily Value
The Reference Daily Intake (RDI) used in nutrition labeling on food and dietary supplement products in the U.S. and Canada is the daily intake level of a nutrient that is considered to be sufficient to meet the requirements of 97–98% of healthy individuals in every demographic in the United States. While developed for the US population, it has been adopted by other countries, though not universally. The RDI is used to determine the Daily Value (DV) of foods, which is printed on nutrition facts labels (as % DV) in the United States and Canada, and is regulated by the Food and Drug Administration (FDA) and by Health Canada respectively. The labels "high", "rich in", or "excellent source of" may be used for a food if it contains 20% or more of the RDI. The labels "good source", "contains", or "provides" may be used on a food if it contains between 10% and 20% of the RDI. The Recommended Dietary Allowances (RDAs) were a set of nutrition recommendations that evolved into both the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called peptides. The individual amino acid residues are bonded together by peptide bonds and adjacent amino acid residues. The sequence of amino acid residue ...

Carbohydrate
In organic chemistry, a carbohydrate () is a biomolecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogen–oxygen atom ratio of 2:1 (as in water) and thus with the empirical formula (where ''m'' may or may not be different from ''n''), which does not mean the H has covalent bonds with O (for example with , H has a covalent bond with C but not with O). However, not all carbohydrates conform to this precise stoichiometric definition (e.g., uronic acids, deoxy-sugars such as fucose), nor are all chemicals that do conform to this definition automatically classified as carbohydrates (e.g. formaldehyde and acetic acid). The term is most common in biochemistry, where it is a synonym of saccharide (), a group that includes sugars, starch, and cellulose. The saccharides are divided into four chemical groups: monosaccharides, disaccharides, oligosaccharides, and polysaccharides. Monosaccharides and disaccharides, the smallest (lower molecular wei ...

Food Energy
Food energy is chemical energy that animals (including humans) derive from their food to sustain their metabolism, including their muscle, muscular activity. Most animals derive most of their energy from aerobic respiration, namely combining the carbohydrates, fats, and protein in nutrition, proteins with oxygen from air or dissolved in water. Other smaller components of the diet, such as organic acids, polyols, and ethanol (drinking alcohol) may contribute to the energy input. Some diet (nutrition), diet components that provide little or no food energy, such as water, dietary mineral, minerals, vitamins, cholesterol, and dietary fiber, fiber, may still be necessary to health and survival for other reasons. Some organisms have instead anaerobic respiration, which extracts energy from food by reactions that do not require oxygen. The energy contents of a given mass of food is usually expressed in the International System of Units, metric (SI) unit of energy, the joule (J), and its ...

Boiling
Boiling is the rapid vaporization of a liquid, which occurs when a liquid is heated to its boiling point, the temperature at which the vapour pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere. There are two main types of boiling: nucleate boiling where small bubbles of vapour form at discrete points, and critical heat flux boiling where the boiling surface is heated above a certain critical temperature and a film of vapor forms on the surface. Transition boiling is an intermediate, unstable form of boiling with elements of both types. The boiling point of water is 100 °C or 212 °F but is lower with the decreased atmospheric pressure found at higher altitudes. Boiling water is used as a method of making it potable by killing microbes and viruses that may be present. The sensitivity of different micro-organisms to heat varies, but if water is held at for one minute, most micro-organisms and viruses are inactivated. Ten ...

Salad
A salad is a dish consisting of mixed, mostly natural ingredients with at least one raw ingredient. They are typically served at room temperature or chilled, though some can be served warm. Condiments and salad dressings, which exist in a variety of flavors, are often used to enhance a salad. Garden salads use a base of leafy greens such as lettuce, arugula/rocket, kale or spinach; they are common enough that the word ''salad'' alone often refers specifically to garden salads. Other types include bean salad, tuna salad, bread salad (e.g. fattoush, panzanella), vegetable salads without leafy greens (e.g. Greek salad, potato salad, coleslaw), sōmen salad (a noodle-based salad), fruit salad, and desserts like jello salad. Salads may be served at any point during a meal: *Appetizer salads — light, smaller-portion salads served as the first course of the meal *Side salads — to accompany the main course as a side dish; examples include potato salad and coleslaw * Main cour ...

Radish
The radish (''Raphanus raphanistrum'' subsp. ''sativus'') is an Eating, edible root vegetable of the family Brassicaceae that was domesticated in Asia prior to Roman Empire, Roman times. Radishes are grown and consumed throughout the world, being mostly eaten raw as a crunchy salad vegetable with a pungency, pungent, slightly spicy flavor, varying in intensity depending on its growing environment. There are numerous variety (botany), varieties, varying in size, flavor, color, and length of time they take to mature. Radishes owe their sharp flavor to the various chemical compounds produced by the plants, including glucosinolate, myrosinase, and isothiocyanate. They are sometimes grown as companion plants and suffer from few pests and diseases. They germinate quickly and grow rapidly, common smaller varieties being ready for consumption within a month, while larger ''daikon'' varieties take several months. Being easy to grow and quick to harvest, radishes are often planted by novi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cabbage
Cabbage, comprising several cultivars of ''Brassica oleracea'', is a leafy green, red (purple), or white (pale green) biennial plant grown as an annual vegetable crop for its dense-leaved heads. It is descended from the wild cabbage ( ''B. oleracea'' var. ''oleracea''), and belongs to the "cole crops" or brassicas, meaning it is closely related to broccoli and cauliflower (var. ''botrytis''); Brussels sprouts (var. ''gemmifera''); and Savoy cabbage (var. ''sabauda''). A cabbage generally weighs between . Smooth-leafed, firm-headed green cabbages are the most common, with smooth-leafed purple cabbages and crinkle-leafed savoy cabbages of both colours being rarer. Under conditions of long sunny days, such as those found at high northern latitudes in summer, cabbages can grow quite large. , the heaviest cabbage was . Cabbage heads are generally picked during the first year of the plant's life cycle, but plants intended for seed are allowed to grow a second year and must be ...

Chinese Cabbage
Chinese cabbage (''Brassica rapa'', subspecies ''pekinensis'' and ''chinensis'') can refer to two cultivar groups of leaf vegetables often used in Chinese cuisine: the Pekinensis Group (napa cabbage) and the Chinensis Group (bok choy). These vegetables are both variant cultivars or subspecies of the turnip and belong to the same genus as such Western staples as cabbage, broccoli, and cauliflower. Both have many variations in name, spelling, and scientific classification, especially bok choy cultivars. History The Chinese cabbage was principally grown in the Yangtze River Delta region, but the Ming dynasty naturalist Li Shizhen popularized it by bringing attention to its medicinal qualities. The variant cultivated in Zhejiang around the 14th century was brought north, and the northern harvest of napa cabbage soon exceeded the southern one. These were then exported back south along the Grand Canal to Hangzhou and traded by sea as far south as Guangdong. Napa cabbage became a s ...

Bok Choy
Bok choy (American English, Canadian English, and Australian English), pak choi (British English) or pok choi (''Brassica rapa'' subsp. ''chinensis'') is a type of Chinese cabbage, used as food. ''Chinensis'' varieties do not form heads and have green leaf blades with lighter bulbous bottoms instead, forming a cluster reminiscent of mustard greens. It has a flavor between spinach and water chestnuts but is slightly sweeter, with a mildly peppery undertone. The green leaves have a stronger flavor than the white bulb. ''Chinensis'' varieties are popular in southern China, East Asia, and Southeast Asia. Being winter-hardy, they are increasingly grown in Northern Europe. Now considered a subspecies of ''Brassica rapa'', this group was originally classified as its own species under the name ''Brassica chinensis'' by Carl Linnaeus. They are a member of the family of Brassicaceae or Cruciferae, also commonly known as the mustards, the crucifers, or the cabbage family. Spelling and naming ...
