Introduction
The Chikoo is the fruit of the evergreen tree Manilkara zapota. It is a slow-growing, long-lived, and ornamental tree, notable for the milky white latex (chicle) that exudes from all parts, which was historically the original base for chewing gum. The fruit is highly prized in tropical regions for its exceptionally sweet, malty flavor and granular, pear-like texture when fully ripe.
Etymology
Sapodilla: Derived from the Spanish term zapotillo, meaning "little sapote," which ultimately comes from the Nahuatl (Aztec) word tzapotl, a general term for soft, sweet fruits.
Chikoo/Chiku: Widely used in South Asia (India, Pakistan) and Southeast Asia. The name is believed to be derived from chicle, the name of the tree's latex.
Naseberry: A common name used in the Caribbean/West Indies.
Description
| Feature | Details |
| Tree | Evergreen, upright, and spreading, reaching 9–15 m (30–49 ft) in cultivation, but can reach over 30 m in the wild. It is highly wind-resistant and all parts exude a sticky, white latex (chicle). |
| Leaves | Glossy, dark green, 5–15 cm long, elliptical to ovate, clustered spirally at the tips of the branches. |
| Flower | Small, inconspicuous, off-white, and bell-shaped, measuring about 1 cm in diameter. The tree flowers almost year-round in the tropics. |
| Fruit | A large, round to oval berry, typically 5–10 cm in diameter. The skin is thin, brown, and scruffy. The flesh is sweet, juicy, soft, and ranges from pale yellow to earthy brown with a slightly grainy texture. |
| Seeds | Usually 1 to 12 black, hard, shiny, flattened, bean-like seeds with a hook at one end. |

Distribution and Habitat
Native Range: Southern Mexico (Yucatán Peninsula) and Central America (Belize, Guatemala, Nicaragua, etc.).
Distribution: Cultivation was spread by the Spanish to the Philippines and subsequently to India and Southeast Asia, where it is now a major crop. It is grown widely throughout the tropical and subtropical lowlands of the world.
Habitat: It is a tropical fruit tree, thriving in warm, humid climates with optimum temperatures between $11^\circ \text{C}$ and $34^\circ \text{C}$. It is quite hardy and can tolerate poor or calcareous (limestone) soils but prefers deep, well-drained sandy loams.
Cultivation
Propagation: Most commonly propagated commercially by grafting (e.g., on Manilkara hexandra rootstock) or air layering (marcotting) to ensure clonal fidelity and early fruiting. Seedlings can take 5–8 years to bear fruit.
Harvest: The fruit is climacteric and must be harvested when mature but still firm and allowed to ripen off the tree. Maturity is judged when the skin loses its roughness and stops exuding a milky latex when scratched.
Peak Season: Bears fruit twice a year, though flowering can be continuous in optimal climates.
Production
India is the world's largest producer of Sapodilla (Chikoo).
Top Producers (Area and Volume): India, Thailand, Mexico, Bangladesh, Indonesia.
Major Indian States: Gujarat, Maharashtra (known for the "Chikoo Belt" of Palghar/Dahanu), Karnataka, Tamil Nadu, and Andhra Pradesh.
Market: The vast majority of the fruit is consumed domestically in the producing countries.
Uses
Edible Fruit: Primarily eaten fresh as a dessert fruit due to its high sweetness. It is also used to make milkshakes, ice cream, jams, custards, and fermented into wine or vinegar.
Chicle: The milky latex harvested from the trunk was historically the main source of the natural base for chewing gum.
Wood: The reddish wood is exceptionally hard, heavy, and durable, used for furniture, flooring, and heavy construction due to its resistance to decay.
Traditional Medicine: Various parts (bark, leaves, seeds) are used traditionally as an astringent, antipyretic (fever reducer), and to treat conditions like diarrhea and coughs.
Phytochemistry
Chikoo is rich in diverse bioactive compounds:
Polyphenols: High concentration of phenolic compounds, including tannins and flavonoids (like quercetin and gallic acid), which contribute to its significant antioxidant activity. The astringent taste of unripe fruit is due to high tannin content.
Saponins and Triterpenes: Present in the fruit, leaves, and bark, contributing to reported anti-inflammatory and antimicrobial properties.
Vitamins and Minerals: Excellent source of Vitamin C and Copper.
Nutrition

Culture
Mayan and Aztec Heritage: The Sapodilla tree holds ancient cultural significance in its native range, with the Maya using its latex (chicle) for chewing and its durable wood for structures like temple lintels.
Popularity in Asia: Despite being native to the Americas, Chikoo has become deeply integrated into the food culture of countries like India, Pakistan, and the Philippines, where it is a beloved and commonly consumed table fruit.
