The Scoville scale is a measurement of pungency of chili peppers and other substances, recorded in Scoville heat units (SHU). It is based on the concentration of capsaicinoids, among which capsaicin is the predominant component.
Capsaicin (8-methyl-N-vanillyl-6-nonenamide) is an active component of chili peppers, which are plants belonging to the genus Capsicum. It is a potent irritant for mammals, including humans, and produces a sensation of burning in any tissue with which it comes into contact. Capsaicin and several related amides (capsaicinoids) are produced as secondary metabolites by chili peppers, likely as deterrents against certain mammals and fungi. Pure capsaicin is a hydrophobic, colorless, highly pungent crystalline solid.
The paprika or bell pepper is the fruit of plants in the Grossum Group of the species Capsicum annuum. Cultivars of the plant produce fruits in different colors, including red, yellow, orange, green, white, chocolate, candy cane striped, and purple. Bell peppers are sometimes grouped with less pungent chili varieties as "sweet peppers". While they are botanically fruits—classified as berries—they are commonly used as a vegetable ingredient or side dish. Other varieties of the genus Capsicum are categorized as chili peppers when they are cultivated for their pungency, including some varieties of Capsicum annuum.
Chili peppers, also spelled chile or chilli, are varieties of berry-fruit plants from the genus Capsicum, which are members of the nightshade family Solanaceae, cultivated for their pungency. Chili peppers are widely used in many cuisines as a spice to add "heat" to dishes. Capsaicin and the related capsaicinoids give chili peppers their intensity when ingested or applied topically. Chili peppers exhibit a range of heat and flavors. This diversity is the reason behind the availability of different types of chili powder, each offering its own taste and heat level.
Capsicum pubescens is a plant of the genus Capsicum (pepper). The species name, pubescens, refers to the hairy leaves of this pepper. The hairiness of the leaves, along with the black seeds, make Capsicum pubescens distinguishable from other Capsicum species. Capsicum pubescens has pungent yellow, orange, red, green or brown fruits.
Capsicum annuum var. glabriusculum, a chili-pepper variety of Capsicum annuum, is native to southern North America and northern South America. Common names include chiltepín, Indian pepper, grove pepper, chiltepe, and chile tepín, as well as turkey, bird’s eye, or simply bird peppers. Tepín is derived from a Nahuatl word meaning "flea". This variety is the most likely progenitor of the domesticated C. annuum var. annuum. Another similar-sized pepper, 'Pequin' is often confused with tepin, although the tepin fruit is round to oval where as the pequin's fruit is oval with a point, and the leaves, stems and plant structures are very different on each plant.
Capsicum annuum, commonly known as paprika, chili pepper, red pepper, sweet pepper, jalapeño, cayenne, or bell pepper, is a fruiting plant from the family Solanaceae (nightshades), within the genus Capsicum which is native to the northern regions of South America and to southwestern North America. The plant produces berries of many colors including red, green, and yellow, often with pungent taste. It is also one of the oldest cultivated crops, with domestication dating back to around 6,000 years ago in regions of Mexico. The genus Capsicum has over 30 species but Capsicum annuum is the primary species in its genus, as it has been widely cultivated for human consumption for a substantial amount of time and has spread across the world. This species has many uses in culinary applications, medicine, self defense, and can even be ornamental.
Oleoresins are semi-solid extracts composed of resin and essential or fatty oil, obtained by evaporation of the solvents used for their production. The oleoresin of conifers is known as crude turpentine or gum turpentine, which consists of oil of turpentine and rosin.
Capsicum chinense, commonly known as a "habanero-type pepper", is a species of chili pepper native to the Americas. C. chinense varieties are well known for their unique flavors and, in many cases, exceptional heat. The hottest peppers in the world are members of this species, with a Scoville Heat Unit score of 2.69 million measured in the C. chinense cultivar, Pepper X in 2023.
Zeaxanthin is one of the most common carotenoids in nature, and is used in the xanthophyll cycle. Synthesized in plants and some micro-organisms, it is the pigment that gives paprika, corn, saffron, goji (wolfberries), and many other plants and microbes their characteristic color.
The poblano is a mild chili pepper originating in Puebla, Mexico. Dried, it is called ancho or chile ancho, from the Spanish word ancho (wide). Stuffed fresh and roasted, it is popular in chiles rellenos poblanos.
Paprika oleoresin is an oil-soluble extract from the fruits of Capsicum annuum or Capsicum frutescens, and is primarily used as a colouring and/or flavouring in food products. It is composed of vegetable oil and capsanthin and capsorubin, the main colouring compounds. Commercial products are generally standardized to contain 7% total caretinoids. It is much milder than capsicum oleoresin, often containing relatively little capsaicin.
Capsorubin is a natural red dye of the xanthophyll class. As a food coloring, it has the E number E160c(ii). Capsorubin is a carotenoid found in red bell pepper and a component of paprika oleoresin. Capsorubin is also found in some species of lily.
Padrón pepper, also called Herbón pepper, is a landrace variety of pepper from the municipality of Padrón in northwestern Spain.
Bird's eye chili or Thai chili is a chili pepper variety from the species Capsicum annuum that is native to Mexico. Cultivated across Southeast Asia, it is used extensively in many Asian cuisines. It may be mistaken for a similar-looking chili derived from the species Capsicum frutescens, the cultivar siling labuyo. Capsicum frutescens fruits are generally smaller and characteristically point upwards. In the Marianas and Guam these are often called boonie peppers or Doni Sali, which can be term for regional wild varieties. The variation between different varieties can be significant for regional dishes or visuals, such as the Thai ornamental varieties.
Capsicum is a genus of flowering plants in the nightshade family Solanaceae, native to the Americas, cultivated worldwide for their edible fruit, which are generally known as "peppers" or "capsicum". Chili peppers grow on five species of Capsicum. Sweet or bell peppers and some chili peppers are Capsicum annuum, making it the most cultivated species in the genus.
Paprika is a spice made from dried and ground red peppers. It is traditionally made from Capsicum annuum varietals in the Longum group, including chili peppers. Paprika can have varying levels of heat, but the chili peppers used for hot paprika tend to be milder and have thinner flesh than those used to produce chili powder. In some languages, but not English, the word paprika also refers to the plant and the fruit from which the spice is made, as well as to peppers in the Grossum group.
The cayenne pepper is a type of Capsicum annuum. It is usually a hot chili pepper used to flavor dishes. Cayenne peppers are a group of tapering, 10 to 25 cm long, generally skinny, mostly red-colored peppers, often with a curved tip and somewhat rippled skin, which hang from the bush as opposed to growing upright. Most varieties are generally rated at 30,000 to 50,000 Scoville units.
Capsicum rhomboideum is a perennial member of the genus Capsicum with 2n=2x=26, and is considered a distant wild relative of the chili pepper. Its fruit do not have any pungency, and are a 0 on the Scoville Heat Unit scale. It gets its name from the rhomboidal to elliptical shape of its leaves. It is native to Mexico, Central America, and Andean region of South America.
