The pomelo, pummelo, or in scientific terms Citrus maxima or Citrus grandis, is the largest citrus fruit from the family Rutaceae and the principal ancestor of the grapefruit.[1] It is a natural, i.e., non-hybrid, citrus fruit, native to Southeast Asia.[1] Similar in taste to a large, sweet grapefruit, the pomelo is commonly consumed and used for festive occasions throughout Southeast Asia.


The etymology of the word "pomelo" derived from Dutch pompelmoes, which is rendered Pampelmuse in German, and pamplemousse in French.[1] Its botanical name, Citrus maxima, means "biggest citrus". In English, the word "pomelo" (also spelled pomello, pummelo, pommelo, pumelo) has become the more common name, although "pomelo" has historically been used for grapefruit. (The 1973 printing of the American Heritage Dictionary, for example, gives grapefruit as the only meaning of "pomelo.")

After a captain Shaddock of an East India Company ship introduced it to Barbados, the fruit was called "shaddock" in English.[2][3] From there the name spread to Jamaica in 1696.[4] It remains a common name for the fruit among English authors.[5] The fruit is also known as jabong in Hawaii and jambola in varieties of English spoken in South Asia.[1]

Description and uses[edit]

The pomelo tree may be 16–50 ft (4.9–15.2 m) tall, possibly with a crooked trunk 4–12 in (10–30 cm) thick, and low-hanging, irregular branches.[1] Leaf petioles are distinctly winged, with alternate, ovate or elliptic shapes 2–8 in (5.1–20.3 cm) long, with a leathery, dull green upper finish, and hairy lower leaf.[1] The flowers — single or in clusters — are fragrant and yellow-white in color.[1]

The pomelo is a large citrus fruit, 6–10 in (15–25 cm) in diameter,[6] usually weighing 2–4 lb (1–2 kg). It has a thicker rind than a grapefruit.[1] Containing 11–18 segments, the flesh tastes like a mild grapefruit (believed to be a hybrid of Citrus maxima and the orange).[1][7] The flesh has little of the common grapefruit bitterness. The enveloping membranous material around the segments is bitter, considered inedible, and usually discarded.[1] There are two varieties: a sweet kind with white flesh, and a sour kind with pinkish flesh, the latter more likely to be used as a ceremony, rather than eaten.[1] The fruit generally contains few, relatively large seeds, but some varieties have numerous seeds.[1]

The juice is regarded as delicious, and the rind is used to make preserves or may be candied.[1] 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, either raw or sprinkled with sugar. In large parts of Southeast Asia where pomelo is native, it is a common dessert, often eaten raw and sprinkled with, or dipped in, a salt mixture. It is eaten in salads.[1] In the Philippines, the juice is mixed with pineapple and made into a pink beverage.[8]

The fruit may have been introduced to China around 100 BC.[1] In East Asia, especially in Cantonese cuisine, braised pomelo pith is used to create dishes that are high in fibre and nutritional value and low in fat.[9]

Propagation and genetic diversity[edit]

The seeds of the pomelo are monoembryonic, producing seedlings identical to their parents, and therefore pomelo is typically grown from seed in Asia.[1] Seeds can be stored for 80 days at 41 °F (5 °C) and with moderate relative humidity.[1] Citrus maxima is usually grafted onto other citrus rootstocks outside Asia; high-quality varieties are propagated by air-layering or by budding onto favored rootstocks.[1]

A wide variability in the physical and chemical characteristics of pomelo occurs across South Asia.[1]


Non-hybrid pomelos[edit]

Possible non-hybrid pomelos[edit]


The pomelo is one of the original citrus species from which the rest of cultivated citrus have been hybridized, (others being citron, mandarin, and to a lesser extent, papedas and kumquat). In particular, the common orange and the grapefruit are presumed to be naturally occurring hybrids between the pomelo and the mandarin, with the pomelo providing the larger size and greater firmness.

The pomelo is employed today in artificial breeding programs:

Raw pomelo flesh is 89% water, 10% carbohydrates, 1% protein, and contains negligible fat (table). A 100 gram reference amount provides 38 calories, and is rich in vitamin C (73% of the Daily Value), with no other micronutrients in significant content (table).

Potential for drug interaction[edit]

As a species of citrus, pomelo may cause adverse effects, similar to those caused by grapefruit, through the inhibition of cytochrome P450-mediated metabolism of prescription drugs such as anti-hypertensives and anticoagulants.[11]
