Cumin (, ; ; Cuminum cyminum) is a in the family , native to the Irano-Turanian Region. Its seeds – each one contained within a fruit, which is dried – are used in the of many cultures in both whole and ground form. Although cumin is used in traditional medicine, there is no high-quality evidence that it is safe or effective as a therapeutic agent.


Etymology and pronunciation
The term comes via comyn, from cymen (which is cognate with Old High German kumin) and cummin, both from the Latin term cuminum. This in turn comes from the κύμινον (kúminon), a Semitic borrowing related to rtl=yes (kammōn) and rtl=yes (kammūn). All of these ultimately derive from Akkadian 𒂵𒈬𒉡 (kamūnu).

Description
Cumin is the dried seed of the herb Cuminum cyminum, a member of the . The cumin plant grows to tall and is harvested by hand. It is an , with a slender, glabrous, branched that is tall and has a diameter of 3–5 cm (–2 in). Each branch has two to three sub-branches. All the branches attain the same height, so the plant has a uniform canopy. The stem is colored grey or dark green. The are long, or , with thread-like leaflets. The are small, white or pink, and borne in . Each umbel has five to seven umbellets. The is a lateral fusiform or 4–5 mm (– in) long, containing two mericarps with a single . Cumin seeds have eight ridges with oil canals. They resemble seeds, being oblong in shape, longitudinally ridged, and yellow-brown in color, like other members of the family Apiaceae () such as caraway, parsley, and .


Confusion with other spices
Cumin is sometimes confused with ( Carum carvi), another spice in the parsley family (). Many European and Asian languages do not distinguish clearly between the two; for example, in both are called jinten. Many and refer to cumin as " caraway" or "spice caraway". The distantly related and Bunium bulbocastanum and the unrelated are both sometimes called black cumin ( q.v.).

They have also been reported from several New Kingdom levels of archaeological sites. In the ancient Egyptian civilization, cumin was used as a spice and as a preservative in mummification.

Cumin was a significant spice for the Minoans in ancient . for cumin appear in archive tablets documenting stores during the Late Minoan period.Castleden, Rodney, "Minoans: Life in Bronze Age Crete”, Routledge, London & New York, 1990, p.52. The ancient Greeks kept cumin at the dining table in its own container (much as pepper is frequently kept today), and this practice continues in . Cumin was also used heavily in ancient Roman cuisine. In India, it has been used for millennia as a traditional ingredient in innumerable recipes, and forms the basis of many other spice blends.

Cumin was introduced to the by Spanish and Portuguese colonists. Black and green cumin are used in . Today, the plant is mostly grown in the Indian subcontinent, , , , and . Since cumin is often used as part of and exported to many countries, the plant can occur as an introduced species in many territories. Bird Seed Aliens in Britain


Cultivation and production

Cultivation areas
is the world's largest producer of cumin, accounting for about 70%. The other major cumin-producing countries are (13%), (5%), UAE (3%), and . India produced 856,000 tons of cumin seed in the 2020–2021 fiscal year.


Climatic requirements
Cumin is a drought-tolerant tropical or subtropical crop. It is vulnerable to frost and has a growth season of 120 frost-free days. The optimum growth temperature ranges are between . The Mediterranean climate is most suitable for its growth. Cultivation of cumin requires a long, hot summer of three to four months. At low temperatures, the leaf color changes from green to purple. High temperatures might reduce growth period and induce early ripening. In India, cumin is sown from October until the beginning of December, and harvesting starts in February. In Syria and Iran, cumin is sown from mid-November until mid-December (extensions up to mid-January are possible) and harvested in June/July.


Grading
The three noteworthy sorts of cumin seeds in the market vary in seed shading, amount of oil, and flavor.


Cultivation parameters
Cumin is grown from seeds. The seeds need for emergence, an optimum of is suggested. Cumin is vulnerable to frost damage, especially at flowering and early seed formation stages. Methods to reduce frost damage are spraying with (0.1%), irrigating the crop prior to frost incidence, setting up , or creating an early-morning smoke cover. The seedlings of cumin are rather small and their vigor is low. Soaking the seeds for 8 hours before sowing enhances germination. For an optimal plant population, a sowing density of is recommended. Fertile, sandy, loamy soils with good aeration, proper drainage, and high oxygen availability are preferred. The pH optimum of the soil ranges from 6.8 to 8.3. Cumin seedlings are sensitive to salinity and emergence from heavy soils is rather difficult. Therefore, a proper seedbed preparation (smooth bed) is crucial for the optimal establishment of cumin.

Two sowing methods are used for cumin, broadcasting and line sowing. For broadcast sowing, the field is divided into beds and the seeds are uniformly broadcast in this bed. Afterwards, they are covered with soil using a rake. For line sowing, shallow furrows are prepared with hooks at a distance of . The seeds are then placed in these furrows and covered with soil. Line sowing offers advantages for intercultural operations such as weeding, hoeing, or spraying. The recommended sowing depth is 1–2 cm and the recommended sowing density is around 120 plants per m2. The water requirements of cumin are lower than those of many other species. Despite this, cumin is often irrigated after sowing to be sure that enough moisture is available for seedling development. The amount and frequency of irrigation depends on the climate conditions.


Cultivation management
The relative humidity in the center of origin of cumin is rather low. High relative humidity (i.e. wet years) favors fungal diseases. Cumin is especially sensitive to blight and wilt. Early-sown crops exhibit stronger disease effects than late-sown crops. The most important disease is Fusarium wilt, resulting in yield losses up to 80%. Fusarium is seed- or soil-borne and it requires distinct soil temperatures for the development of epidemics. Inadequate fertilization might favor Fusarium epidemics. Cumin blight ( Alternaria) appears in the form of dark brown spots on leaves and stems. When the weather is cloudy after flowering, the incidence of the disease is increased. Another, but less important, disease is . Incidence of powdery mildew in early development can cause drastic yield losses because no seeds are formed. Later in development, powdery mildew causes discolored, small seeds.

Pathogens can lead to high reductions in crop yield. Cumin can be attacked by aphids ( ) at the flowering stage. They suck the sap of the plant from tender parts and flowers. The plant becomes yellow, the seed formation is reduced (yield reduction), and the quality of the harvested product decreases. Heavily infested plant parts should be removed. Other important pests are the ( Petrobia latens) which frequently attack the crop. Since the mites mostly feed on young leaves, the infestation is more severe on young inflorescences.

The open canopy of cumin is another problem. Only a low proportion of the incoming light is absorbed. The leaf area index of cumin is low (about 1.5). This might be a problem because weeds can compete with cumin for essential resources such as water and light and thereby lower yield. The slow growth and the short stature of cumin favors weed competition additionally. Two hoeing and weeding sessions (30 and 60 days after sowing) are needed for the control of weeds. During the first weeding session (30 days after sowing), thinning should be done, as well, to remove excess plants. The use of preplant or pre-emergence is very effective in India, but this kind of herbicide application requires soil moisture for a successful weed control.


Breeding
Cumin is a species with 14 (i.e. 2n = 14). The chromosomes of the different varieties have morphological similarities with no distinct variation in length and volume. Most of the varieties available today are selections. The variabilities of yield and yield components are high. Varieties are developed by sib mating in enclosed chambers or by biotechnology. Cumin is a cross-pollinator, i.e. the breeds are already hybrids. Therefore, methods used for breeding are in vitro regenerations, DNA technologies, and gene transfers. The cultivation of cumin allows the production of genetically identical plants. The main sources for the explants used in vitro regenerations are embryos, , shoot internodes, leaves, and . One goal of cumin breeding is to improve its resistance to biotic (fungal diseases) and abiotic (cold, drought, salinity) stresses. The potential genetic variability for conventional breeding of cumin is limited and research about cumin genetics is scarce.


Uses
Cumin seed is used as a for its distinctive flavor and aroma. Cumin can be found in some cheeses, such as , and in some traditional breads from France. Cumin can be an ingredient in (often or Mexican-style) and is found in blends, , , , , and , and is used to flavor numerous commercial food products. In Indian and other South Asian cuisine, it is often combined with in a powdered mixture called .

Cumin can be used ground or as whole seeds. It imparts an earthy, warming and aromatic character to food, making it a staple in certain stews and soups, as well as spiced gravies such as curry and chili. It is also used as an ingredient in some pickles and pastries.


Traditional
In India, the seeds are powdered and used in different forms such as kashaya (decoction), arishta (fermented decoction), and vati (tablet/pills), and processed with (a semifluid clarified butter). In traditional medicine practices of several countries, dried cumin seeds are assumed to have medicinal purposes, although no scientific evidence has been found for its effectiveness as a drug or medicine.


Volatiles and essential oil
, , and are the major volatile components of cumin oil, which is used for a variety of , , and . Cumin oil may be used as an ingredient in some .


Aroma
Cumin's flavor and warm aroma are due to its essential oil content, primarily the cuminaldehyde. Other aroma compounds of toasted cumin are the substituted , 2-ethoxy-3-isopropylpyrazine, , and 2-methoxy-3-methylpyrazine. Other components include , , , and .


Nutritional value
Cumin seeds are 8% water, 18% protein, 22% , and 44% (table).

In a reference amount of , cumin seeds provide 375 of and high amounts of the for , , and several dietary minerals, especially iron, magnesium, and manganese (table).
