Origin and history of peppers
Geographic origin
The pepper is native to the tropical and subtropical regions of the American continent, specifically the area extending from Mexico to northern South America. Archaeobotanical and genetic studies indicate that this species was domesticated more than 6 years ago by Native American populations, along with other varieties of peppersThe greatest genetic diversity is still found in Mexico today, confirming its role as the main center of domestication.
Pre-Columbian History
Before the arrival of Europeans, bell peppers and their close relatives were already widely cultivated by pre-Columbian civilizations, including the Aztecs, Mayans, and Incas. In these cultures, they were a staple food, often combined with corn and beans in traditional dishes. Their consumption was not limited to the ripe fruit: young green peppers were also used, as were some hotter varieties to spice up dishes.
Worldwide distribution
After Christopher Columbus's discovery of the New World in the late 15th century, bell peppers were introduced to Europe, likely via the Spanish and Portuguese sea routes. Its cultivation spread rapidly throughout the Mediterranean, taking advantage of the warm, sunny climate. By the 16th century, they were already known in many parts of Europe, North Africa, and the Near East. Trade and the species' adaptation to different environments later led to its introduction to Asia, particularly India and China, where they became an important ingredient in various culinary traditions.
Evolution of varieties
Over the centuries, breeders and farmers have developed many varieties of peppers with distinct shapes, sizes, colors, and flavors. The distinction between sweet and peppers forts, both belonging to Capsicum annuum, has been strengthened through selection to reduce or eliminate capsaicin in certain lines. This work has resulted in cultivars with fleshy, sweet fruits, enjoyed in cuisines around the world.
Pepper species and varieties
Taxonomic position
Pepper belongs to the genus Capsicum, which includes around thirty species, of which only five are commonly cultivated: Capsicum annuum, Capsicum frutescens, capsicum chinense, Capsicum baccatum et capsicum pubescens. Among them, Capsicum annuum is the most widespread species worldwide and includes both sweet peppers and many hot peppers.
Diversity within Capsicum annuum
The species Capsicum annuum presents a great morphological variability. We mainly distinguish:
- Sweet peppers, with fleshy fruits, lacking any spiciness, cubic, elongated or conical in shape.
- Mild, finer-fleshed peppers, such asEspelette and ox horn, with an elongated shape.
- Hot peppers, such asbird and Cayenne, containing more capsaicin, often smaller and thinner.
These forms are the result of centuries of human selection aimed at adapting the plant to specific culinary uses and different growing environments.
Main varieties of sweet peppers
Among the most well-known varieties of sweet peppers are:
- The square or block pepper: with four lobes, often red, green or yellow, used raw or cooked.
- The elongated pepper: like the “ox horn” variety, with tender and sweet flesh.
- The conical pepper: appreciated grilled or stuffed, some varieties are close to the ox horn.
- Miniature varieties: often used as an aperitif or for culinary decoration.
Selection and hybridization
Modern breeding programs have resulted in hybrid cultivars that are resistant to certain diseases, suitable for greenhouse cultivation, and capable of producing uniform fruits. These hybrids can also have a more varied color palette, ranging from ivory white to dark purple, including shades of chocolate or intense orange.
Taste particularity
Unlike chili peppers, also from Capsicum annuum, the pepper is devoid or almost devoid of capsaicin, the molecule responsible for the sensation of spiciness. This absence gives it a mild flavor, which can be slightly sweet when fully ripe.
Botanical description of pepper
Port and stem
Pepper is a herbaceous plant belonging to the family of Solanaceae, the same as that of the tomato (Solanum lycopersicum) and theEggplant (Solanum melongena). Depending on growing conditions and climate, it can behave as an annual or persist for several years as a short-lived perennial. Its upright, branched stem has a semi-woody consistency at the base and can reach between 50 centimeters and 1,5 meters in height.
Sheets
The leaves, simple and entire, are arranged alternately along the stems. Their limbus is generally oval to lanceolate, with an acute apex (point) and an attenuated base, light to dark green in color. The surface is smooth or slightly glossy, while the veins are marked and paler in color. The average leaf length varies from 5 to 12 centimeters, depending on the variety and growing conditions.
Flowers
The flowers appear singly or in small groups of two to three, inserted in the axils of the leaves on a pedicel short. They are hermaphrodites, which allows them to self-fertilize, but can also be pollinated by insects. The corolla is generally white, sometimes tinged with green or purple, composed of five to seven petals fused at the base. The green calyx is formed of persistent sepals. The stamens, five to seven in number, surround a central pistil ending in a slightly enlarged stigma.
Fruits
The pepper fruit is a hollow berry with a fleshy wall, whose shape and size vary greatly depending on the cultivar: elongated, conical, rectangular, or lobed. When immature, it is generally green, then its color evolves during maturation towards red, yellow, orange, brown, or purple, depending on the pigments present. The surface is smooth, shiny, and sometimes slightly waxy. The interior of the fruit is divided into chambers by membranous septa, in the center of which is attached the placenta, supporting numerous seeds. These are flat, rounded, cream to pale yellow in color, and have a finely granular surface.
Geographic distribution and natural environment of peppers
Area of origin
The pepper is native to Central and South America, with a particularly high concentration of genetic diversity in Mexico. Wild populations grow naturally in warm, sunny, well-drained areas, often on the edges of open forests or in open habitats with low vegetation.
Worldwide distribution
Following its domestication by pre-Columbian peoples, the pepper was introduced to Europe in the late 15th century by Spanish and Portuguese explorers. It then spread widely throughout regions with Mediterranean, subtropical, and tropical climates. Today, it is cultivated on all continents, from warm temperate zones to the humid tropics, thanks to varieties adapted to different climatic conditions.
Natural ecological conditions
Wild, Capsicum annuum thrives in light, well-drained soils rich in organic matter, with full sun exposure. It prefers temperatures between 20 and 30 °C and does not tolerate prolonged cold spells well. Moderate rainfall, combined with good soil aeration, promotes its growth, while excess moisture can cause rapid root dieback.
Ecological adaptation and plasticity
The species is characterized by a high ecological plasticity, which allows it to adapt to varied environments, from coastal plains to moderate altitude areas. Human selection has accentuated this adaptability, giving rise to cultivars capable of producing in extreme conditions, such as in greenhouses in cold regions or in irrigated cultivation in arid zones.
Uses of pepper
Culinary uses
Pepper is one of the vegetables the most versatile in world gastronomy. Eaten raw, it brings crunch and freshness to salads and raw vegetables. When cooked, it develops milder and sweeter aromas, whether steamed, baked, grid, sauté, make us or simmered. Depending on its color and stage of maturity, its taste varies: green peppers are more herbaceous and slightly bitter, while red, yellow or orange ones are sweeter.
It is incorporated into many traditional cuisines: ratatouille and piperade in the south of France, paella in Spain, peperonata in Italy, ajvar in the Balkans, and fajitas and salsas in Mexico. The elongated varieties are often stuffed, while the conical or square types are well suited to roasting and drying.
Food processing
The pepper is processed in various forms: pickled, marinated peppersPeppers are used in purées, sauces, and dehydrated powders. Some red varieties are dried and then ground to produce mild spices, such as paprika, which is widely used in Central and Eastern Europe. The food industry also uses peppers as an ingredient to color and flavor preparations, thanks to their natural carotenoid pigments.
Non-culinary uses
Outside of food, bell peppers have a few other uses. Their pigments, particularly capsanthin and capsorubin, are used as natural colorants in certain food and cosmetic products. In some agricultural research programs, pepper varieties Capsicum annuum are also used as model plants for the study of disease resistance and climate adaptation, due to their relatively short growth cycle and genetic diversity.
