Pomegranate

The pomegranate (Punica granatum) is a fruit-bearing deciduous shrub in the family Lythraceae, subfamily Punicoideae, that grows between 5 and 10 m (16 and 33 ft) tall. The pomegranate is rich in symbolic and mythological associations in many cultures. The pomegranate is thought to have originated from Afghanistan and Iran before being introduced and exported to other parts of Asia, Africa, and Europe.

It was introduced into Spanish America in the late 16th century and into California by Spanish settlers in 1769. It is widely cultivated throughout West Asia and Caucasus region, South Asia, Central Asia, north and tropical Africa, the drier parts of Southeast Asia, and the Mediterranean Basin. The fruit is typically in season in the Southern Hemisphere from March to May, and in the Northern Hemisphere from September to February.

Pomegranate and juice are variously used in baking, cooking, juice blends, garnishes, non-alcoholic drinks, and cocktails.

Etymology

The name pomegranate derives from medieval Latin pōmum 'apple' and grānātum 'seeded'. Possibly stemming from the old French word for the fruit, pomme-grenade, the pomegranate was known in early English as apple of Grenada—a term which today survives only in heraldic blazons. This is a folk etymology, confusing the Latin granatus with the name of the Spanish city of Granada, which is derived from an unrelated Arabic word.

Garnet derives from Old French grenat by metathesis, from Medieval Latin granatum as used in a different meaning 'of a dark red color'. This derivation may have originated from pomum granatum, describing the color of pomegranate pulp, or from granum, referring to 'red dye, cochineal'.

The modern French term for pomegranate, grenade, has given its name to the military grenade.

Pomegranates were colloquially called wineapples or wine-apples in Ireland, although this term has fallen out of use. It still persists at the Moore Street open-air market, in central Dublin.

Description

The pomegranate is a shrub or small tree growing 5 to 10 m (16 to 33 ft) high, with multiple spiny branches. It is long-lived, with some specimens in France surviving for 200 years. P. granatum leaves are opposite or subopposite, glossy, narrow oblong, entire, 3–7 cm (1+1⁄4–2+3⁄4 in) long and 2 cm (3⁄4 in) broad. The flowers are bright red and 3 cm (1+1⁄4 in) in diameter, with three to seven petals. Some fruitless varieties are grown for the flowers alone.

Fruit

The pomegranate fruit husk is red-purple in color with an outer, hard pericarp, and an inner, spongy mesocarp (white "albedo"), which comprises the fruit inner wall where seeds attach. Membranes of the mesocarp are organized as nonsymmetric chambers that contain seeds which are embedded without attachment to the mesocarp. Pomegranate seeds are characterized by having sarcotesta, thick fleshy seed coats derived from the integuments or outer layers of the ovule's epidermal cells. The number of seeds in a pomegranate can vary from 200 to about 1,400.

Botanically, the fruit is a berry with edible seeds and pulp produced from the ovary of a single flower. The fruit is intermediate in size between a lemon and a grapefruit, 5–12 cm (2–4+1⁄2 in) in diameter with a rounded shape and thick, reddish husk.

In mature fruits, the juice obtained by compressing the seeds yields a tart flavor due to low pH (4.4) and high contents of polyphenols, which may cause a red indelible stain on fabrics. The pigmentation of pomegranate juice primarily results from the presence of anthocyanins and ellagitannins.

Cultivation

P. granatum is grown for its vegetable crop, and as ornamental trees and shrubs in parks and gardens. Mature specimens can develop sculptural twisted-bark, multiple trunks and a distinctive overall form. Pomegranates are drought-tolerant, and can be grown in dry areas with either a Mediterranean winter rainfall climate or in summer rainfall climates. In wetter areas, they can be prone to root decay from fungal diseases. They can tolerate moderate frost, down to about −12 °C (10 °F).

Insect pests of the pomegranate can include the butterflies Virachola isocrates, Iraota timoleon, Deudorix epijarbas, and the leaf-footed bug Leptoglossus zonatus, and fruit flies and ants are attracted to unharvested ripe fruit. Pomegranate grows easily from seed, but is commonly propagated from 25 to 50 cm (10 to 20 in) hardwood cuttings to avoid the genetic variation of seedlings. Air layering is also an option for propagation, but grafting fails.

Varieties

P. granatum var. nana is a dwarf variety of P. granatum popularly planted as an ornamental plant in gardens and larger containers, and used as a bonsai specimen tree. It could well be a wild form with a distinct origin. It has gained the Royal Horticultural Society's Award of Garden Merit.

The only other species in the genus Punica is the Socotran pomegranate (P. protopunica), which is endemic to the Socotran archipelago of four islands located in the Arabian Sea, the largest island of which is also known as Socotra. The territory is part of Yemen. It differs in having pink (not red) flowers and smaller, less sweet fruit.

Cultivars

P. granatum has more than 500 named cultivars, but evidently has considerable synonymy in which the same genotype is named differently across regions of the world.

Several characteristics between pomegranate genotypes vary for identification, consumer preference, preferred use, and marketing, the most important of which are fruit size, exocarp color (ranging from yellow to purple, with pink and red most common), seed-coat color (ranging from white to red), the hardness of seed, maturity, juice content and its acidity, sweetness, and astringency.

Production and export

The leading producers globally are India and China, followed by Iran, Turkey, Afghanistan, the US, Iraq, Pakistan, Syria, and Spain. During 2019, Chile, Peru, Egypt, Israel, India, and Turkey supplied pomegranates to the European market. Chile was the main supplier to the United States market, which has a limited supply from Southern California. China was self-sufficient for its pomegranate supply in 2019, while other South Asia markets were supplied mainly by India. Pomegranate production and exports in South Africa competed with South American shipments in 2012–18, with export destinations including Europe, the Middle East, the United Kingdom, and Russia. South Africa imports pomegranates mainly from Israel.

History

The pomegranate is native to a region from modern-day Iran to northern India. Pomegranates have been cultivated throughout the Middle East, India, and Mediterranean region for several millennia, and it is also cultivated in the Central Valley of California and in Arizona. Pomegranates may have been domesticated as early as the fifth millennium BC, as they were one of the first fruit trees to be domesticated in the eastern Mediterranean region.

Carbonized exocarp of the fruit has been identified in early Bronze Age levels of Tell es-Sultan (Jericho) in the West Bank, as well as late Bronze Age levels of Hala Sultan Tekke on Cyprus and Tiryns. A large, dry pomegranate was found in the tomb of Djehuty, the butler of Queen Hatshepsut in Egypt; Mesopotamian records written in cuneiform mention pomegranates from the mid-third millennium BC onwards. Waterlogged pomegranate remains have been identified at the circa 14th century BC Uluburun shipwreck off the coast of Turkey. Other goods on the ship include perfume, ivory and gold jewelry, suggesting that pomegranates at this time may have been considered a luxury good. Other archaeological finds of pomegranate remains from the Late Bronze Age have been found primarily in elite residences, supporting this inference.

It is also extensively grown in southern China and in Southeast Asia, whether originally spread along the route of the Silk Road or brought by sea traders. Kandahar is famous in Afghanistan for its high-quality pomegranates.

Although not native to Korea or Japan, the pomegranate is widely grown there and many cultivars have been developed. It is widely used for bonsai because of its flowers and for the unusual twisted bark the older specimens can attain. The term "balaustine" (Latin: balaustinus) is also used for a pomegranate-red color.

Spanish colonists later introduced the fruit to the Caribbean and America (Spanish America). However, in the English colonies, it was less at home: "Don't use the pomegranate inhospitably, a stranger that has come so far to pay his respects to thee," the English Quaker Peter Collinson wrote to the botanizing John Bartram in Philadelphia, 1762. "Plant it against the side of thy house, nail it close to the wall. In this manner it thrives wonderfully with us, and flowers beautifully, and bears fruit this hot year. I have twenty-four on one tree... Doctor Fothergill says, of all trees this is most salutiferous to mankind."

The pomegranate had been introduced as an exotic to England the previous century, by John Tradescant the Elder, but the disappointment that it did not set fruit there led to its repeated introduction to the American colonies, even New England. It succeeded in the South: Bartram received a barrel of pomegranates and oranges from a correspondent in Charleston, South Carolina, 1764. John Bartram partook of "delitious" pomegranates with Noble Jones at Wormsloe Plantation, near Savannah, Georgia, in September 1765. Thomas Jefferson planted pomegranates at Monticello in 1771; he had them from George Wythe of Williamsburg.

Use

Culinary

Pomegranate juice can be sweet or sour, but most fruits are moderate in taste, with sour notes from the acidic ellagitannins contained in the juice. Pomegranate juice has long been a common drink in Europe and the Middle East, and is distributed worldwide. Pomegranate juice is also used as a cooking ingredient. In Syria, pomegranate juice is added to intensify the flavor of some dishes such as kibbeh safarjaliyeh.

Grenadine syrup, commonly used in cocktail, originally consisted of thickened and sweetened pomegranate juice, but today is typically a syrup made just of sugar and commercially produced natural and artificial flavors, preservatives, and food coloring, or using substitute fruits (such as berries).

Before tomatoes (a New World fruit) arrived in the Middle East, pomegranate juice, pomegranate molasses, and vinegar were widely used in many Iranian foods; this mixture still found in traditional recipes such as fesenjān, a thick sauce made from pomegranate juice and ground walnuts, usually spooned over duck or other poultry and rice, and in ash-e anar (pomegranate soup).

Pomegranate seeds are used as a spice known as anar dana (from Persian: anar + dana, pomegranate + seed), most notably in Indian and Pakistani cuisine. Dried whole seeds can often be obtained in ethnic Indian markets. These seeds are separated from the flesh, dried for 10–15 days, and used as an acidic agent for chutney and curry preparation. Ground anardana is also used, which results in a deeper flavoring in dishes and prevents the seeds from getting stuck in teeth. Seeds of the wild pomegranate variety known as daru from the Himalayas are regarded as high-quality sources for this spice.

Dried pomegranate seeds, found in some natural specialty food markets, still contain some residual water, maintaining a natural sweet and tart flavor. Dried seeds can be used in several culinary applications, such as trail mix, granola bars, or as a topping for salad, yogurt, or ice cream.

In Turkey, pomegranate sauce (Turkish: nar ekşisi) is used as a salad dressing, to marinate meat, or simply to drink straight. Pomegranate seeds are also used in salads and sometimes as garnish for desserts such as güllaç. Pomegranate syrup, also called pomegranate molasses, is used in muhammara, a roasted red pepper, walnut, and garlic spread popular in Syria and Turkey.

In Greece, pomegranate is used in many recipes, including kollivozoumi, a creamy broth made from boiled wheat, pomegranates, and raisins, legume salad with wheat and pomegranate, traditional Middle Eastern lamb kebabs with pomegranate glaze, pomegranate eggplant relish, and avocado-pomegranate dip. Pomegranate is also made into a liqueur, and as a popular fruit confectionery used as ice cream topping, mixed with yogurt, or spread as jam on toast.

In Mexico, pomegranate seeds are commonly used to adorn the traditional dish chiles en nogada, representing the red of the Mexican flag in the dish which evokes the green (poblano pepper), white (nogada sauce) and red (pomegranate seeds) tricolor.

Other uses

Pomegranate peels may be used to stain wool and silk in the carpet industry.

Nutrition

The edible portion of raw pomegranate is 78% water, 19% carbohydrates, 2% protein, and 1% fat (table). A 100 g (3.5 oz) serving of pomegranate sarcotesta provides 12% of the Daily Value (DV) for vitamin C, 16% DV for vitamin K, and 10% DV for folate (table). Pomegranate seeds are a rich source of dietary fiber (20% DV) which is entirely contained in the edible seeds.

Research

Phytochemicals

Processing

The phenolic content of pomegranate juice is degraded by processing and pasteurization techniques.

Juice

The most abundant phytochemicals in pomegranate juice are polyphenols, including the hydrolyzable tannins called ellagitannins formed when ellagic acid and gallic acid bind with a carbohydrate to form pomegranate ellagitannins, also known as punicalagins. The red color of the juice is attributed to anthocyanins, such as delphinidin, cyanidin, and glycosides of pelargonidin. Generally, an increase in juice pigmentation occurs during fruit ripening.

Peel

Pomegranate peel contains high amount of polyphenols, condensed tannins, catechins, and prodelphinidins. The higher phenolic content of the peel yields extracts for use in dietary supplements and food preservatives.

Seed

Pomegranate seed oil contains punicic acid (65%), palmitic acid (5%), stearic acid (2%), oleic acid (6%), and linoleic acid (7%).

Health claims

Despite limited research data, manufacturers and marketers of pomegranate juice have liberally used results from preliminary research to promote products. In February 2010, the FDA issued a warning letter to one such manufacturer, POM Wonderful, for using published literature to make illegal claims of unproven anti-disease effects.

In May 2016, the US Federal Trade Commission declared that POM Wonderful could not make health claims in its advertising, followed by a US Supreme Court ruling that declined a request by POM Wonderful to review the court ruling, upholding the FTC decision.

Symbolism

Ancient Iran

Pomegranate, known as anār in Persian, is a symbol of fertility, blessing and favor in Iranian belief. Pomegranates are sacred in the Zoroastrian religion and Zoroastrians used it in their religious rituals. The yellow color of the pomegranate stamens symbolizes the sun and light.

Pomegranate tree has been one of the most sacred and holiest plants in Iran and is believed to be grown from the spot where the blood of Siavash (the legendary Iranian character who is known for his innocence) and has been mentioned in Iranian Pahlavi scripts as a fruit of heaven. It is also believed that the invulnerability of Esfandiar (Iranian legend) was related to this sacred fruit. The Zoroastrians of Iran, believe that pomegranate is a blest fruit as it is served in their festivals like Mehregan and Nowruz, and especially in their wedding ceremonies to wish for the newly married couple to have a healthy child in the future. They also used to plant a pomegranate tree in their fire temples to use its leaves in their ceremonies.

During the Iranian tradition, Yalda Night, people come together on winter solstice and eat pomegranate fruit to celebrate the victory of light over darkness.

In a relief from Persepolis, Darius the Great is holding a pomegranate flower with two buds. This Achaemenid king is accepting the representatives of all the subordinate lands of Greater Iran to his presence, while holding a large flower in his hand as a sign of peace and friendship.

Ancient Egypt

Ancient Egyptians regarded the pomegranate as a symbol of prosperity and ambition. It was referred to by the Semitic names of jnhm or nhm. According to the Ebers Papyrus, one of the oldest medical writings from around 1500 BC, Egyptians used the pomegranate for treatment of tapeworm and other infections.

Ancient and modern Greece

A pomegranate is displayed on coins from Side, as Side was the name for pomegranate in the local language, which is the city's name. The ancient Greek city of Side was in Pamphylia, a former region on the southern Mediterranean coast of Asia Minor (modern-day Antalya province, Turkey).

The Greeks were familiar with the fruit far before it was introduced to Rome via Carthage, and it figures in multiple myths and artworks. In Ancient Greek mythology, the pomegranate was known as the "fruit of the dead", and believed to have sprung from the blood of Adonis.

The myth of Persephone, the goddess of the underworld, prominently features her consumption of pomegranate seeds, requiring her to spend a certain number of months in the underworld every year. The number of seeds and therefore months vary. During the months that Persephone sits on the throne of the underworld beside her husband Hades, her mother Demeter mourned and no longer gave fertility to the earth. This was an ancient Greek explanation for the seasons.

According to Carl A. P. Ruck and Danny Staples, the chambered pomegranate is also a surrogate for the poppy's narcotic capsule, with its comparable shape and chambered interior.

In another Greek myth, a girl named Side ("pomegranate") killed herself on her mother's grave in order to avoid suffering rape at the hands of her own father Ictinus. Her blood transformed into a pomegranate tree.

In the fifth century BC, Polycleitus took ivory and gold to sculpt the seated Argive Hera in her temple. She held a scepter in one hand and offered a pomegranate, like a "royal orb", in the other. "About the pomegranate I must say nothing," whispered the traveller Pausanias in the second century, "for its story is somewhat of a holy mystery." The pomegranate has a calyx shaped like a crown. In Jewish tradition, it has been seen as the original "design" for the proper crown.

Within the Heraion at the mouth of the Sele, near Paestum, Magna Graecia, is a chapel devoted to the Madonna del Granato, "Our Lady of the Pomegranate", "who by virtue of her epithet and the attribute of a pomegranate must be the Christian successor of the ancient Greek goddess Hera", observes the excavator of the Heraion of Samos, Helmut Kyrieleis.

In modern times, the pomegranate still holds strong symbolic meanings for the Greeks. When one buys a new home, it is conventional for a house guest to bring as a first gift a pomegranate, which is placed under/near the ikonostasi (home altar) of the house, as a symbol of abundance, fertility, and good luck. When Greeks commemorate their dead, they make kollyva as offerings, which consist of boiled wheat, mixed with sugar and decorated with pomegranate. Pomegranate decorations for the home are very common in Greece and sold in most home goods stores.

Ancient Israel and Judaism

Hebrew Bible

Some Jewish scholars believe the pomegranate was the forbidden fruit in the Garden of Eden.

Pomegranates were known in Ancient Israel as the fruits that the scouts brought to Moses to demonstrate the fertility of the "Promised Land". The Book of Exodus describes the me'il ("robe of the ephod") worn by the Hebrew high priest as having pomegranates embroidered on the hem, alternating with golden bells, which could be heard as the high priest entered and left the Holy of Holies. According to the Books of Kings, the capitals of the two pillars (Jachin and Boaz) that stood in front of Solomon's Temple in Jerusalem were engraved with pomegranates. Solomon is said to have designed his coronet based on the pomegranate's "crown" (calyx).

Pomegranates are one of the Seven Species (Hebrew: שבעת המינים, Shiv'at Ha-Minim) of fruits and grains enumerated in the Hebrew Bible (Deuteronomy 8:8) as special products of the Land of Israel, and the Songs of Solomon mentions pomegranate six times and contains this particular quote: "Thy lips are like a thread of scarlet, and thy speech is comely: thy temples are like a piece of a pomegranate within thy locks." (Song of Solomon 4:3).

Historical and traditional use

The pomegranate appeared on the ancient coins of Judaea, see Hasmonean, Herodian and First Jewish Revolt coinage.

The handles of Torah scrolls, when not in use, are sometimes covered with decorative silver globes similar in shape to pomegranates (Torah rimmonim).

Consuming pomegranates on Rosh Hashana, the Jewish New Year, is traditional because, with its numerous seeds, it symbolizes fruitfulness.

Talmud and Kabbalah

The pomegranate is said to have 613 seeds representing the 613 commandments of the Torah, but it is a misconception. There is no clear source for this claim, although it is used as a metaphor in the Talmud for numerous good deeds.

In European Christian motifs

In the earliest incontrovertible appearance of Christ in a mosaic, a fourth-century floor mosaic from Hinton St Mary, Dorset, now in the British Museum, the bust of Christ and the chi rho are flanked by pomegranates. Pomegranates continue to be a motif often found in Christian religious decoration. They are often woven into the fabric of vestments and liturgical hangings or wrought in metalwork. Pomegranates figure in many religious paintings by the likes of Sandro Botticelli and Leonardo da Vinci, often in the hands of the Virgin Mary or the infant Jesus. The fruit, broken or bursting open, is a symbol of the fullness of Jesus' suffering and resurrection.

In Islam

Chapter 55 of the Quran mentions the pomegranate as a "favour" among many to be offered to those fearful to the "Lord" in "two Gardens".

Armenia

The pomegranate is one of the main fruits in Armenian culture (alongside apricots and grapes). Its juice is used with Armenian food and wine. The pomegranate is a symbol in Armenia, representing fertility, abundance, and marriage. It is also a semireligious icon. For example, the fruit played an integral role in a wedding custom widely practiced in ancient Armenia; a bride was given a pomegranate fruit, which she threw against a wall, breaking it into pieces. Scattered pomegranate seeds ensured the bride future children.

The Color of Pomegranates, a movie directed by Sergei Parajanov, is a biography of the Armenian ashug Sayat-Nova (King of Song) which attempts to reveal the poet's life visually and poetically rather than literally.

Azerbaijan

Every fall the Goychay Pomegranate Festival is held in the city of Goychay.

China

Introduced to China during the Han dynasty (206 BC–220 AD), the pomegranate (Chinese: 石榴; pinyin: shíliu), in older times, was considered an emblem of fertility and numerous progeny. Pictures of the ripe fruit with the seeds bursting forth were often hung in homes to bestow fertility and bless the dwelling with numerous offspring, an important facet of traditional Chinese culture.

In modern times, the pomegranate has been used to symbolise national cohesion and ethnic unity by Xi Jinping, urging the Chinese population to "stick together like pomegranate seeds".

India

In some Hindu traditions, the pomegranate (Sanskrit: dāḍima) symbolizes prosperity and fertility, and is associated with both Bhumi (the earth goddess) and Ganesha (the one fond of the many-seeded fruit).

Kurdish culture

Pomegranate is an important fruit and symbol in Kurdish culture. It is accepted as a symbol of abundance and a sacred fruit of ancient Kurdish religions. Pomegranate is used as a symbol of abundance in Kurdish carpets.
