About

The tomato (/təmeɪtoʊ/ or /təmɑːtoʊ/) is the edible berry of the plant Solanum lycopersicum, commonly known as the tomato plant. The species originated in western South America, Mexico, and Central America. The Nahuatl word tomatl gave rise to the Spanish word tomate, from which the English word tomato derived. Its domestication and use as a cultivated food may have originated with the indigenous peoples of Mexico. The Aztecs used tomatoes in their cooking at the time of the Spanish conquest of the Aztec Empire, and after the Spanish encountered the tomato for the first time after their contact with the Aztecs, they brought the plant to Europe, in a widespread transfer of plants known as the Columbian exchange. From there, the tomato was introduced to other parts of the European-colonized world during the 16th century.

Tomatoes are a significant source of umami flavor. They are consumed in diverse ways: raw or cooked, and in many dishes, sauces, salads, and drinks. While tomatoes are fruits—botanically classified as berries—they are commonly used culinarily as a vegetable ingredient or side dish.

Numerous varieties of the tomato plant are widely grown in temperate climates across the world, with greenhouses allowing for the production of tomatoes throughout all seasons of the year. Tomato plants typically grow to 1–3 meters (3–10 ft) in height. They are vines that have a weak stem that sprawls and typically needs support. Indeterminate tomato plants are perennials in their native habitat, but are cultivated as annuals. (Determinate, or bush, plants are annuals that stop growing at a certain height and produce a crop all at once.) The size of the tomato varies according to the cultivar, with a range of 1–10 cm (1⁄2–4 in) in width.

HISTORY


The wild ancestor of the tomato, Solanum pimpinellifolium, is native to western South America. These wild versions were the size of peas. The first evidence of domestication points to the Aztecs and other peoples in Mesoamerica, who used the fruit fresh and in their cooking. The Spanish first introduced tomatoes to Europe, where they became used in Spanish food. In France, Italy and northern Europe, the tomato was initially grown as an ornamental plant. It was regarded with suspicion as a food because botanists recognized it as a nightshade, a relative of the poisonous belladonna. This was exacerbated by the interaction of the tomato's acidic juice with pewter plates. The leaves and fruit contain tomatine, which in large quantities would be toxic. However, the ripe fruit contains a much lower amount of tomatine than the immature fruit.

    Mesoamerica

    The exact date of domestication is unknown; by 500 BC, it was already being cultivated in southern Mexico and probably other areas. The Pueblo people are thought to have believed that those who witnessed the ingestion of tomato seeds were blessed with powers of divination. The large, lumpy variety of tomato, a mutation from a smoother, smaller fruit, originated in Mesoamerica, and may be the direct ancestor of some modern cultivated tomatoes.

    Spanish distribution

    Spanish conquistador Hernán Cortés may have been the first to transfer a small yellow tomato to Europe after he captured the Aztec city of Tenochtitlan, now Mexico City, in 1521. The earliest discussion of the tomato in European literature appeared in a herbal written in 1544 by Pietro Andrea Mattioli, an Italian physician and botanist, who suggested that a new type of eggplant had been brought to Italy that was blood red or golden color when mature and could be divided into segments and eaten like an eggplant—that is, cooked and seasoned with salt, black pepper, and oil. It was not until ten years later that tomatoes were named in print by Mattioli as pomi d'oro, or "golden apples".

    After the Spanish colonization of the Americas, the Spanish distributed the tomato throughout their colonies in the Caribbean. They also took it to the Philippines, from where it spread to southeast Asia and then the entire Asian continent. The Spanish also brought the tomato to Europe. It grew easily in Mediterranean climates, and cultivation began in the 1540s. It was probably eaten shortly after it was introduced, and was certainly being used as food by the early 17th century in Spain.

    China

    The tomato was introduced to China, likely via the Philippines or Macau, in the 1500s. It was given the name 番茄 fānqié (foreign eggplant), as the Chinese named many foodstuffs introduced from abroad, but referring specifically to early introductions

    Italy

    The recorded history of tomatoes in Italy dates back to at least 31 October 1548, when the house steward of Cosimo de' Medici, the grand duke of Tuscany, wrote to the Medici private secretary informing him that the basket of tomatoes sent from the grand duke's Florentine estate at Torre del Gallo "had arrived safely". Tomatoes were grown mainly as ornamentals early on after their arrival in Italy. For example, the Florentine aristocrat Giovanvettorio Soderini wrote how they "were to be sought only for their beauty", and were grown only in gardens or flower beds. The tomato's ability to mutate and create new and different varieties helped contribute to its success and spread throughout Italy. However, in areas where the climate supported growing tomatoes, their habit of growing to the ground suggested low status. They were not adopted as a staple of the peasant population because they were not as filling as other fruits already available. Additionally, both toxic and inedible varieties discouraged many people from attempting to consume or prepare any other varieties. In certain areas of Italy, such as Florence, the fruit was used solely as a tabletop decoration, until it was incorporated into the local cuisine in the late 17th or early 18th century. The earliest discovered cookbook with tomato recipes was published in Naples in 1692, though the author had apparently obtained these recipes from Spanish sources

    Britain

    Tomatoes were not grown in England until the 1590s. One of the earliest cultivators was John Gerard, a barber-surgeon. Gerard's Herbal, published in 1597, and largely plagiarized from continental sources, is also one of the earliest discussions of the tomato in England. Gerard knew the tomato was eaten in Spain and Italy. Nonetheless, he believed it was poisonous (in fact, the plant and raw fruit do have low levels of tomatine, but are not generally dangerous; see below). Gerard's views were influential, and the tomato was considered unfit for eating (though not necessarily poisonous) for many years in Britain and its North American colonies.

    However, by the mid-18th century, tomatoes were widely eaten in Britain, and before the end of that century, the Encyclopædia Britannica stated the tomato was "in daily use" in soups, broths, and as a garnish. They were not part of the average person's diet, and though by 1820 they were described as "to be seen in great abundance in all our vegetable markets" and to be "used by all our best cooks", reference was made to their cultivation in gardens still "for the singularity of their appearance", while their use in cooking was associated with exotic Italian or Jewish cuisine

    Middle East and North Africa

    The tomato was introduced to cultivation in the Middle East by John Barker, British consul in Aleppo c. 1799 to 1825. Nineteenth century descriptions of its consumption are uniformly as an ingredient in a cooked dish. In 1881, it is described as only eaten in the region "within the last forty years". Today, the tomato is a critical and ubiquitous part of Middle Eastern cuisine, served fresh in salads (e.g., Arab salad, Israeli salad, Shirazi salad and Turkish salad), grilled with kebabs and other dishes, made into sauces, and so on.

    United States

    The earliest reference to tomatoes being grown in British North America is from 1710, when herbalist William Salmon reported seeing them in what is today South Carolina. They may have been introduced from the Caribbean. By the mid-18th century, they were cultivated on some Carolina plantations, and probably in other parts of the Southeast as well. Thomas Jefferson, who ate tomatoes in Paris, sent some seeds back to America. Some early American advocates of the culinary use of the tomato included Michele Felice Cornè and Robert Gibbon Johnson.[24] Many Americans considered tomatoes to be poisonous at this time; and in general, they were grown more as ornamental plants than as food. In 1897, W. H. Garrison addressed the Medico-Legal Society of New York stating, "The belief was once transmitted that the tomato was sinisterly dangerous." He recalled in his youth tomatoes were dubbed "love-apples or wolf-apples" and they were shunned as "globes of the devil."[25]

    Alexander W. Livingston receives much credit for developing numerous varieties of tomato for both home and commercial gardeners.

    Early tomato breeders included Henry Tilden in Iowa and a Dr. Hand in Baltimore. The U.S. Department of Agriculture's 1937 yearbook declared that "half of the major varieties were a result of the abilities of the Livingstons to evaluate and perpetuate superior material in the tomato." Livingston's first breed of tomato, the Paragon, was introduced in 1870, the beginning of a great tomato culture enterprise in the county. In 1875, he introduced the Acme, which was said to be involved in the parentage of most of the tomatoes introduced by him and his competitors for the next twenty-five years.

    When Livingston began his attempts to develop the tomato as a commercial crop, his aim had been to grow tomatoes smooth in contour, uniform in size, and sweet in flavor. He eventually developed over seventeen different varieties of the tomato plant. Today, the crop is grown in every state in the Union.

    Modern commercial varieties

    The poor taste and lack of sugar in modern garden and commercial tomato varieties resulted from breeding tomatoes to ripen uniformly red. This change occurred after discovery of a mutant "u" phenotype in the mid-20th century, so named because the fruits ripened uniformly. This was widely cross-bred to produce red fruit without the typical green ring around the stem on uncross-bred varieties. Prior to general introduction of this trait, most tomatoes produced more sugar during ripening, and were sweeter and more flavorful.

    Etymology


    The word tomato comes from the Spanish tomate, which in turn comes from the Nahuatl word tomatl [ˈtomat͡ɬ], meaning 'swelling fruit'; also 'fat water' or 'fat thing'. The native Mexican tomatillo is tomate. When Aztecs started to cultivate the fruit to be larger, sweeter and red, they called the new variety xitomatl (or jitomates) (pronounced [ʃiːˈtomatɬ]), ('plump with navel' or 'fat water with navel'). The specific name lycopersicum (from the 1753 book Species Plantarum) is of Greek origin (λύκοπερσικων, lykopersikon), meaning 'wolf peach'.

BOTANY

Description

tomato flower unripe tomato

Tomato plants are vines, initially decumbent, typically growing 180 cm (6 ft) or more above the ground if supported, although erect bush varieties have been bred, generally 100 cm (3 ft 3 in) tall or shorter. Indeterminate types are "tender" perennials, dying annually in temperate climates (they are originally native to tropical highlands), although they can live up to three years in a greenhouse in some cases. Determinate types are annual in all climates

Tomato plants are dicots, and grow as a series of branching stems, with a terminal bud at the tip that does the actual growing. When the tip eventually stops growing, whether because of pruning or flowering, lateral buds take over and grow into other, fully functional, vines.

Tomato vines are typically pubescent, meaning covered with fine short hairs. The hairs facilitate the vining process, turning into roots wherever the plant is in contact with the ground and moisture, especially if the vine's connection to its original root has been damaged or severed

The leaves are 10–25 cm (4–10 in) long, odd pinnate, with five to nine leaflets on petioles,[44] each leaflet up to 8 cm (3 in) long, with a serrated margin; both the stem and leaves are densely glandular-hairy

Their flowers, appearing on the apical meristem, have the anthers fused along the edges, forming a column surrounding the pistil's style. Flowers in domestic cultivars can be self-fertilizing. The flowers are 1–2 cm (1⁄2–3⁄4 in) across, yellow, with five pointed lobes on the corolla; they are borne in a cyme of three to 12 together.

Although in culinary terms, tomato is regarded as a vegetable, its fruit is classified botanically as a berry.[45] As a true fruit, it develops from the ovary of the plant after fertilization, its flesh comprising the pericarp walls. The fruit contains hollow spaces full of seeds and moisture, called locular cavities. These vary, among cultivated species, according to type. Some smaller varieties have two cavities, globe-shaped varieties typically have three to five, beefsteak tomatoes have a great number of smaller cavities, while paste tomatoes have very few, very small cavities.

Fruit versus vegetable


Botanically, a tomato is a fruit—a berry, consisting of the ovary, together with its seeds, of a flowering plant. However, the tomato is considered a "culinary vegetable" because it has a much lower sugar content than culinary fruits; because it is more savoury (umami) than sweet, it is typically served as part of a salad or main course of a meal, rather than as a dessert. Tomatoes are not the only food source with this ambiguity; bell peppers, cucumbers, green beans, aubergines/eggplants, avocados, and squashes of all kinds (such as courgettes/zucchini and pumpkins) are all botanically fruit, yet cooked as vegetables.

The confusion on whether tomatoes are fruits or vegetables has led to legal dispute in the United States. In 1887, U.S. tariff laws that imposed a duty on vegetables, but not on fruit, caused the tomato's status to become a matter of legal importance. In Nix v. Hedden, the U.S. Supreme Court settled the tariff controversy on 10 May 1893, by declaring that the tomato is a vegetable, based on the popular definition that classifies vegetables by use—they are generally served with dinner and not dessert. The holding of this case applies only to the interpretation of the Tariff of 1883, and the court did not purport to reclassify the tomato for botanical or other purposes.

TYPES

Tomatoes come in different sizes, shapes, and water content, which can help determine what kind to grow and how to use them. Here are some of the most common types:

  • Beefsteak tomato: Among the largest fruits, beefsteaks have a juicy, meaty texture and classic flavor. Round, slightly flattened fruits are superior slicers for sandwiches, salads, and caprese
  • Campari tomato: Also known as tomatoes on the vine. Golf-ball-sized fruits have low acidity, exceptionally sweet flavor, and juicy texture. Good for snacking, salads, salsa, roasting, and bruschetta.
  • Pear tomato: Small pear-shaped fruits have a sweet mild flavor and juicy texture. Plants are heavy producers over a long time. Good for snacking, salads, and preserves.
  • Plum tomato: Popular plum tomatoes are Roma and San Marzano. The water content is low and texture is firm, making these a good choice for tomato sauce, paste, roasting, drying, and canning. Fruits are mellow tasting, medium sized, and oval shaped.
  • Salad tomato: Rounded fruits, 2-3 inches in diameter, are perfect for slicing on sandwiches or chopped in salads. Somewhat tart and juicy, these have a good balance of acid and sweet.
  • Grape tomato: Similar to plum tomatoes but smaller, the oval-shaped fruits grow in clusters similar to cherry types but have a thicker, meatier texture, and milder flavor. Good for snacking, salads, kebabs, and roasting.
  • Cherry tomato: Bite-sized rounded fruits that grow in clusters are juicy and sweet tasting. Good for snacking, salads, kebabs, roasting, and quick sauces.

Determinate, indeterminate, or semi-determinate?

All tomatoes are either determinate, indeterminate, or semi-determinate. It is important to keep these definitions in mind when choosing what tomatoes to grow—depending on your growing space and how you want to use them

  • Determinate: ("bush tomatoes")
    • Plant grow 1-3 feet tall
    • Ideal for patios, containers, and small space gardens.
    • Produce one big crop and die off near the end of the growing season.
    • Because fruits ripen all at once, good for larger quantity uses such as canning, sauces, and drying.
    • On plant labels, these will be abbreviated as DET.
  • Indeterminate: ("vining tomatoes")
    • Plants grow up to 10 feet tall and need sturdy support.
    • More suited to raised beds and larger vegetable plots.
    • Continue to grow and produce fruit throughout the growing season.
    • On plant labels, these will be abbreviated as IND or INDET.
  • Semi-determinate
    • More compact than indeterminate plants
    • Produce fruit throughout the growing season

Heirloom vs hybrid?

  • Heirloom: Heirloom tomatoes have been around for hundreds of years. They tend to have the best flavor and come true from seed, which means that you will get the exact same variety from seed saved from the previous year.
  • Hybrid: Hybrid tomatoes are a cross between two varieties and bred for particular traits such as disease-resistance and cold hardiness. They can be somewhat less flavorful than heirlooms and will not come true from seed.

HOW LONG DO TOMATOES TAKE TO GROW?

Tomatoes can also be classified by how long it takes for the plant to grow and fruit to ripen.

  • Early season: Varieties bred to grow and ripen quickly—in 65 days or less. These are a good choice for cooler climates and shorter growing seasons.
  • Mid season: Maturity takes 70-80 days, with fruit production in mid-summer.
  • Late season: These take the longest to mature, 80-100 days. Fruit tends to be bigger and better tasting, as they’ve had more time to mature on the vine.
Variety Days take to grow
Early season 65 days or less
Mid season 70-80 days
Late season 80-100 days
Tomato plant after 7 days, 27 days, 52 days after planting

PRODUCTION

In 2021, world production of tomatoes was 189 million tonnes, with China accounting for 35% of the total, followed by India, the European Union, Turkey, and the United States as major producers

HOW OLD ARE THESE TOMATOES?

This 52 million-year-old fossil is the world’s oldest tomato

By Todd Venezia

Published Jan. 10, 2017, 9:19 p.m. ET

Scientists searching a prehistoric lake bed in southern Argentina recently uncovered the fossilized remains of a tomato that dates back 52.2 million years.

The discovery of the ancient edible shows that tomatoes have existed some 30 million years longer than researchers previously had thought.

The sample — which was found in an area known as Laguna del Hunco in an area called Chubut, according to the Mirror — is actually thought to be so old that it is likely the ancestor to the potato, the cucumber and even tobacco.

The tomato is similar to the Mexican husk tomato, and it wound up being preserved for eons after it fell into a lake next to a volcano.

The water had very little oxygen in it, and that helped the fossilization process, the Mirror reported.

USES

Culinary

Though it is botanically a berry, a subset of fruit, the tomato is considered a vegetable for culinary purposes. It has a strong savoury umami flavour, rather than significant sweetness (see above). Chef Heston Blumenthal observed that the inner pulp had more flavour that the flesh; a subsequent academic study in which he participated confirmed that the pulp had up to eleven times more glutamic acid, which carries umami flavour, than the flesh.

Although tomatoes originated in the Americas, the tomato is now grown and eaten around the world. It is used in diverse ways, including raw in salads or in slices, stewed, incorporated into a wide variety of dishes, or processed into ketchup or tomato soup. Unripe green tomatoes can also be breaded and fried, used to make salsa, or pickled. Tomato juice is sold as a drink, and is used in cocktails such as the Bloody Mary.

Tomatoes have become extensively used in Mediterranean cuisine as a key ingredient in pizza and many pasta sauces.[6] Tomatoes are also used in Spanish and Catalan dishes, such as gazpacho and pa amb tomàquet.

Storage

Tomatoes keep best unwashed at room temperature and out of direct sunlight. It is not recommended to refrigerate them as they take a mealy texture and lose flavour.

Storing stem down can prolong shelf life, as it may keep from rotting too quickly.

Unripe tomatoes can be kept in a paper bag to ripen.

Tomatoes are easy to preserve whole, chopped, or as tomato sauce or concentrated paste by home canning. The fruit can also be preserved by drying, sometimes in the sun where climate permits, and sold either in bags or in jars with oil.
