The pomelo ( /ˈpɒmɪloʊ,ˈpʌm-/ POM-il-oh, PUM-; [2] [3] Citrus maxima), from the family Rutaceae, is the largest citrus fruit, and the principal ancestor of the grapefruit. [4] It is a natural, non-hybrid, citrus fruit, native to Southeast Asia. [4] Similar in taste to a sweet grapefruit, the pomelo is commonly consumed and used for festive occasions throughout Southeast Asia and East Asia. As with the grapefruit, phytochemicals in the pomelo have the potential for drug interactions.
The pomelo tree may be 5–15 meters (16–50 feet) tall, possibly with a crooked trunk 10–30 centimeters (4–12 inches) thick, and low-hanging, irregular branches. [4] Their leaf petioles are distinctly winged, with alternate, ovate or elliptic shapes 5–20 cm (2–8 in) long, with a leathery, dull green upper layer, and hairy under-leaf. [4] The flowers — single or in clusters — are fragrant and yellow-white in color. [4]
The fruit is large, 15–25 cm (6–10 in) in diameter, [5] usually weighing 1–2 kilograms (2–4 pounds). It has a thicker rind than a grapefruit, [4] and is divided into 11 to 18 segments. The flesh tastes like mild grapefruit, with a little of its common bitterness (the grapefruit is a hybrid of the pomelo and the orange). [4] [6] The enveloping membranes around the segments are chewy and bitter, considered inedible, and usually discarded. [4] There are at least sixty varieties. [7] The fruit generally contains a few, relatively large seeds, but some varieties have numerous seeds. [4]
According to the Oxford English Dictionary, the etymology of the word "pomelo" is uncertain. [8] It may be derived from Dutch pompelmoes. [4] Its botanical name, Citrus maxima, means "the biggest citrus". In English, the word "pomelo" (also spelt pummelo, pumelo, pomello, pommelo) has become the more common name, although "pomelo" has historically been used for grapefruit.
After introduction into Barbados by 'Captain Shaddock' of the East India Company (apparently Philip Chaddock, who visited the island in the late 1640s [9] ), the fruit was called shaddock in English. [10] [11] From there the name spread to Jamaica in 1696. [12] The fruit is also known as jambola in varieties of English spoken in South Asia. [4]

Raw pomelo flesh is 89% water, 10% carbohydrates, 1% protein, and contains negligible fat (table). A 100 gram reference amount provides 159 kilojoules (38 kilocalories) of food energy, and is rich in vitamin C (73% of the Daily Value), with no other micronutrients in significant content (table).
Pomelo, while not itself toxic, may cause adverse interactions with some prescription drugs similar to those caused by grapefruit and some other citrus fruits, through the inhibition of cytochrome P450-mediated metabolism of prescription drugs including anti-hypertensives and anticoagulants. [15]
The pomelo is one of the original citrus species from which cultivated citrus fruits have been hybridized, others being citron, mandarin, and to a lesser extent, papedas and kumquat. In particular, the common orange is presumed to be a naturally occurring hybrid between the pomelo and the mandarin, with the pomelo as larger and firmer of the two. The grapefruit was originally also presumed to be a naturally occurring hybrid of the pomelo and the mandarin; however, genome analysis conducted more than two centuries after this presumption was made shows that it is actually a backcrossed hybrid between a pomelo and a sweet orange which is why 63% of the grapefruit's genome comes from the pomelo. [16]
The pomelo is employed today in artificial breeding programs:
The flesh and juice can be consumed, and the rind is used to make preserves, or may be candied. [4] In Brazil, the thick skin may be used for making a sweet conserve, while the spongy pith of the rind is discarded. In Sri Lanka, it is often eaten as a dessert, sometimes sprinkled with sugar. In large parts of Southeast Asia where pomelo is native it is commonly eaten as a dessert, often sprinkled with salt or dipped in a salt mixture, but it may be made into salads. [4] In the Philippines, a pink beverage is made from pomelo and pineapple juice. [20]
The fruit may have been introduced to China around 100 BCE. [4] In East Asia, especially in Cantonese cuisine, braised pomelo pith is used to make dishes that are high in fibre and low in fat. [21]
The seeds of the pomelo are monoembryonic, producing seedlings with genes from both parents, but they are usually similar to the tree they grow from and therefore pomelo are typically grown from seeds in Asia. [4] Seeds can be stored for 80 days at a temperature of 5 °C (41 °F) with moderate relative humidity. [4] Citrus maxima is usually grafted onto other citrus rootstocks outside Asia to produce trees that are identical to the parent; high-quality varieties are propagated by air-layering or by budding onto favored rootstocks. [4]
The physical and chemical characteristics of pomelo vary widely across South Asia. [4]
Citrus is a genus of flowering trees and shrubs in the family Rutaceae. Plants in the genus produce citrus fruits, including important crops such as oranges, mandarins, lemons, grapefruits, pomelos, and limes.
The grapefruit is a subtropical citrus tree known for its relatively large, sour to semi-sweet, somewhat bitter fruit. The interior flesh is segmented and varies in color from pale yellow to dark pink/red.
The mandarin orange, also known as mandarin or mandarine, is a small, rounded citrus tree fruit. Treated as a distinct species of orange, it is usually eaten plain or in fruit salads. Tangerines are a group of orange-colored citrus fruit consisting of hybrids of mandarin orange with some pomelo contribution.
Citrus cavaleriei, the Ichang papeda, is a slow-growing species of papeda that has characteristic lemon-scented foliage and flowers.
The tangerine is a type of citrus fruit that is orange in color, that is considered either a variety of Citrus reticulata, the mandarin orange, or a closely related species, under the name Citrus tangerina, or yet as a hybrid of mandarin orange varieties, with some pomelo contribution.
The Jamaican tangelo, also known by proprietary names uglifruit, uglifruit, and uniq fruit, is a citrus fruit that arose on the island of Jamaica through the natural hybridization of a tangerine or orange with a grapefruit, and is thus a tangelo. The original tree is believed to have been a hybrid formed from varieties of Seville orange, grapefruit and tangerine.
The tangelo, Citrus × tangelo, is a citrus fruit hybrid of a Citrus reticulata variety, such as mandarin orange or tangerine, and a Citrus maxima variety, such as a pomelo or grapefruit. The name is a portmanteau of 'tangerine' and 'pomelo'.
Yuzu is a citrus fruit and plant in the family Rutaceae of East Asian origin. Yuzu has been cultivated mainly in East Asia, though it has also recently been grown in New Zealand, Australia, Spain, Italy, and France.
The tangor is a citrus fruit hybrid of the mandarin orange and the sweet orange. The name "tangor" is a formation from the "tang" of tangerine and the "or" of "orange." Also called the temple orange, its thick rind is easy to peel and its bright orange pulp is sour-sweet and full-flavoured.
An oroblanco, oro blanco, or sweetie (Israel) is a sweet seedless citrus hybrid fruit similar to grapefruit. It is often referred to as oroblanco grapefruit.
Ponkan ; Citrus poonensis; "Chinese Honey Orange") is a high-yield sweet Citrus cultivar with large fruits in the size of an orange. It is a citrus hybrid, though it was once thought to be a pure mandarin.
Zest is a food ingredient that is prepared by scraping or cutting from the rind of unwaxed citrus fruits such as lemon, orange, citron, and lime. Zest is used to add flavor to foods.
An orange, also called sweet orange to distinguish it from the bitter orange, is the fruit of a tree in the family Rutaceae. Botanically, this is the hybrid Citrus × sinensis, between the pomelo and the mandarin orange. The chloroplast genome, and therefore the maternal line, is that of pomelo. The sweet orange has had its full genome sequenced.
The ponderosa lemon is a citrus hybrid of a pomelo and a citron. It is not the same as the 'Yuma Ponderosa' lemon-pomelo hybrid used as citrus rootstock.
Cam sành or King orange is a citrus hybrid originating in Vietnam.
A mandelo is a citrus fruit that is smaller than a grapefruit, has yellow or yellow-green coloured skin and bright yellow or yellow-orange flesh, but is sweeter than a grapefruit.
Citrus taxonomy refers to the botanical classification of the species, varieties, cultivars, and graft hybrids within the genus Citrus and related genera, found in cultivation and in the wild.
Banpeiyu is a cultivar of pomelo which produces extremely large fruits.
Citrus × deliciosa is a citrus hybrid mandarin orange with just under 6 % pomelo ancestry. It is related to the ponkan.
The New Zealand grapefruit, also known as the Poorman, Poorman orange, poorman's orange, poor man's orange, and goldfruit, is a type of citrus fruit grown in New Zealand. Despite its name, it is not genetically a true grapefruit, but rather is believed to be a hybrid between a pomelo and a mandarin or tangelo.
