Broccoli
Broccoli (''Brassica oleracea'' var. ''italica'') is an edible green plant in the Brassicaceae, cabbage family (family Brassicaceae, genus ''Brassica'') whose large Pseudanthium, flowering head, plant stem, stalk and small associated leafy greens, leaves are eaten as a vegetable. Broccoli is classified in the Brassica_oleracea#Cultivar_groups, Italica cultivar group of the species ''Brassica oleracea''. Broccoli has large flower heads, or florets, usually dark green, arranged in a tree-like structure branching out from a thick plant stem, stalk, which is usually light green. Leaves surround the mass of flower heads. Broccoli resembles cauliflower, a different but closely related cultivar group of the same ''Brassica'' species. It can be eaten either raw or cooked. Broccoli is a particularly rich source of vitamin C and vitamin K. Contents of its characteristic sulfur-containing glucosinolate compounds, isothiocyanates and sulforaphane, are diminished by boiling but are better p ...

Brassica Oleracea
''Brassica oleracea'', also known as wild cabbage in its uncultivated form, is a plant of the family Brassicaceae. The species originated from feral populations of related plants in the Eastern Mediterranean, where it was most likely first cultivated. It has many common cultivars used as vegetables, including cabbage, broccoli, cauliflower, kale, Brussels sprout, Collard (plant), collard, Savoy cabbage, kohlrabi, and gai lan. Description Wild ''B. oleracea'' is a tall biennial plant, biennial or perennial plant that forms a stout Rosette (botany), rosette of large leaves in the first year. The grayish-green leaves are fleshy and thick, helping the plant store water and nutrients in difficult environments. In its second year, a woody spike grows up to tall, from which branch off stems with long clusters of yellow four-petaled flowers. Taxonomy Origins According to the Triangle of U theory, ''B. oleracea'' is very closely related to five other species of the genus ...

Cauliflower
Cauliflower is one of several vegetables cultivated from the species '' Brassica oleracea'' in the genus '' Brassica'', which is in the Brassicaceae (or mustard) family. Cauliflower usually grows with one main stem that carries a large, rounded "head" made of tightly clustered, immature white or off-white flower buds called the "curd". Typically, only the "head" is eaten. An annual plant that reproduces by seed, the cauliflower head is composed of a (generally) white inflorescence meristem. Although cauliflower heads resemble those in broccoli, the latter differs in having flower buds as the edible portion. The global cauliflower production (combined with broccoli) in 2023 was 26.5 million tonnes, led by China and India with 72% of the total. Description There are four major groups of cauliflower. # Italian: This specimen is diverse in appearance, biennial, and annual in type. This group includes white, Romanesco, and various brown, green, purple, and yellow cultiva ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broccolo
Romanesco broccoli (also known as broccolo romanesco, romanesque cauliflower, or simply romanesco) is in fact a cultivar of the cauliflower (''Brassica oleracea'' var. ''botrytis''), not broccoli (''Brassica oleracea'' var. ''italica''). It is one of two types of broccoflower. It is an edible flower bud of the species ''Brassica oleracea'', which also includes regular broccoli and cauliflower. It is chartreuse in color and has a striking form that naturally approximates a fractal. Romanesco has a nutty flavor and a firmer texture than white cauliflower or broccoli when cooked. Description Romanesco superficially resembles a cauliflower, but it is chartreuse in color, with the form of a natural fractal. Nutritionally, romanesco is rich in vitamin C, vitamin K, dietary fiber, and carotenoids. Fractal structure The inflorescence (the bud) is self-similar in character, with the branched meristems making up a logarithmic spiral, giving a form approximating a natural fractal; e ...

Rapini
Rapini (broccoli rabe or raab) () is a green cruciferous vegetables, cruciferous vegetable, with the leaves, buds, and stems all being edible; the buds somewhat resemble broccoli. Rapini is known for its bitter taste, and is particularly associated with Mediterranean cuisine. It is a particularly rich dietary source of vitamin K. 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'', or ''Brassica rapa'' subsp. ''sylvestris'' var. ''esculenta''. 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. Culinary use The flavor of rapini has ... [...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 m ...

Stir-fry
Stir frying ( zh, c= 炒, p=chǎo, w=ch'ao3, cy=cháau) is a cooking technique in which ingredients are fried in a small amount of very hot oil while being stirred or tossed in a wok. The technique originated in China and in recent centuries has spread into other parts of Asia and the West. It is similar to sautéing in Western cooking technique. Wok frying may have been used as early as the Han dynasty (206 BC – 220 AD) for drying grain, not for cooking. It was not until the Ming dynasty (1368–1644) that the wok reached its modern shape and allowed quick cooking in hot oil. However, there is research indicating that metal woks and stir-frying of dishes were already popular in the Song dynasty (960–1279), and stir-frying as a cooking technique is mentioned in the 6th-century AD Qimin Yaoshu. Stir frying has been recommended as a healthy and appealing method of preparing vegetables, meats, and fish, provided calories are kept at a reasonable level. The English-la ...

Brassica Oleracea Var
''Brassica'' () is a genus of plants in the cabbage and mustard family (Brassicaceae). The members of the genus are informally known as cruciferous vegetables, cabbages, mustard plants, or simply brassicas. Crops from this genus are sometimes called ''cole crops''derived from the Latin ''caulis'', denoting the stem or stalk of a plant. The genus ''Brassica'' is known for its important agricultural and horticultural crops and also includes a number of weeds, both of wild taxa and escapees from cultivation. ''Brassica'' species and varieties commonly used for food include bok choy, broccoli, cauliflower, cabbage, choy sum, kohlrabi, napa cabbage, rutabaga, turnip and some seeds used in the production of canola oil and the condiment mustard. Over 30 wild species and hybrids are in cultivation, plus numerous cultivars and hybrids of cultivated origin. Most are seasonal plants ( annuals or biennials), but some are small shrubs. ''Brassica'' plants have been the subject of much scie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vegetable
Vegetables are edible parts of plants that are consumed by humans or other animals as food. This original meaning is still commonly used, and is applied to plants collectively to refer to all edible plant matter, including edible flower, flowers, fruits, edible plant stem, stems, leaf vegetable, leaves, list of root vegetables, roots, and list of edible seeds, seeds. An alternative definition is applied somewhat arbitrarily, often by culinary and cultural tradition; it may include savoury fruits such as tomatoes and courgettes, flowers such as broccoli, and seeds such as Pulse (legume), pulses, but exclude foods derived from some plants that are fruits, flowers, nut (fruit), nuts, and cereal grains. Originally, vegetables were collected from the wild by hunter-gatherers and entered cultivation in several parts of the world, probably during the period 10,000 BC to 7,000 BC, when a new History of agriculture, agricultural way of life developed. At first, plants that g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isothiocyanate
In organic chemistry, isothiocyanate is a functional group as found in compounds with the formula . Isothiocyanates are the more common isomers of thiocyanates, which have the formula . Occurrence Many isothiocyanates from plants are produced by enzymatic conversion of metabolites called glucosinolates. A prominent natural isothiocyanate is allyl isothiocyanate, also known as mustard oils. Cruciferous vegetables, such as bok choy, broccoli, cabbage, cauliflower, kale, and others, are rich sources of glucosinolate precursors of isothiocyanates. Structure The and distances are 117 and 158 pm. By contrast, in methyl thiocyanate, and distances are 116 and 176 pm. Typical bond angles for in aryl isothiocyanates are near 165°. Again, the thiocyanate isomers are quite different with angle near 100°. In both isomers the angle approaches 180°. Synthesis Allyl thiocyanate isomerizes to the isothiocyanate: : Isothiocyanates can be prepared by treating organ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
