Rambutan is a tropical fruit that belongs to the same family as the lychee and longan fruits. The fruit is small and round, about the size of a golf ball, and covered in a red or yellow skin that is covered in soft, hairy spines.
When the skin is peeled away, a white, juicy flesh is revealed that surrounds a single seed. The flesh has a sweet and slightly acidic flavor, similar to a grape. Seed is not edible and should be discarded.
Rambutan is a good source of vitamin C, fiber, and antioxidants. It is often eaten fresh as a snack or used in desserts and sweet dishes. It can also be canned or dried for later use. In some countries, rambutan is used in traditional medicine for its various health benefits.
Wild ancestors
The wild ancestors of Rambutan (Nephelium lappaceum) are believed to have originated in the Malay-Indonesia region of Southeast Asia. These wild varieties are not as widely cultivated as the commercial cultivars that we see today. Wild Rambutan trees can be found growing in the rainforests of Malaysia, Indonesia, and other neighboring countries.
The wild varieties of Rambutan differ from the commercial cultivars in many ways, including their size, taste, and appearance. Wild Rambutan fruits are typically smaller than commercial varieties and have a slightly different taste. They also have a harder outer skin and a more fibrous flesh.
History
Rambutan is a tropical fruit native to Southeast Asia and is believed to have originated in the Malay Archipelago, specifically the island of Sumatra in Indonesia. The fruit's name comes from the Malay word "rambut," which means hair, referring to the hairy spines that cover the fruit's outer skin.
The exact origins of the rambutan are unknown, but it is believed to have been cultivated in Southeast Asia for centuries. The fruit was introduced to other parts of the world, including India, Sri Lanka, and the Philippines, during the 19th century.
Rambutan was first introduced to the Western world by French botanist Pierre Poivre, who brought the fruit to the island of Mauritius in the 18th century. From there, the fruit was introduced to other parts of the world, including Africa, South America, and the Caribbean.
Today, rambutan is widely cultivated in tropical regions of the world, including Indonesia, Malaysia, Thailand, the Philippines, and parts of Africa and South America. It is a popular fruit in Southeast Asian cuisine and is enjoyed fresh or canned. It is also used in various desserts, jams, and juices.
Cultivars
Over time, farmers in Southeast Asia have selectively bred Rambutan trees to produce larger, sweeter, and more desirable fruit. Today, there are many different cultivars of Rambutan grown around the world, each with its unique characteristics and flavor. Here are some of the most popular cultivars:

Production
According to data from the Food and Agriculture Organization (FAO) of the United Nations, the total global production of rambutan was approximately 928,000 metric tons in 2019.
The largest producers of rambutan in the world are Indonesia, Thailand, and the Philippines. Other significant producing countries include Malaysia, Vietnam, Sri Lanka, and India. Rambutan is also grown in some African countries such as Madagascar and Tanzania, as well as in parts of South and Central America.
It's worth noting that while rambutan is a popular fruit in many countries, its production levels are relatively small compared to other fruits such as bananas, apples, and oranges.
The production of rambutan typically begins with the planting of rambutan seeds or the propagation of seedlings. Rambutan trees grow well in warm, humid climates with well-drained soil. They are often planted in orchards or small farms and require regular watering and fertilization.
The rambutan tree takes approximately 5-7 years to bear fruit, with the fruiting season typically occurring between June and September. The tree produces clusters of fruit, each containing 10-20 individual fruits. The fruit has a reddish or yellowish skin with soft spines, and its white flesh is sweet and juicy with a single seed in the center.
During the fruiting season, the fruit is harvested by hand-picking the clusters of fruit from the tree. The harvested fruit is then sorted and graded according to its size, color, and quality.
Rambutan is a perishable fruit, and it must be handled carefully to ensure that it does not spoil during transportation. The fruit is often packed in ventilated containers or baskets and transported to local markets or exported to other countries.
As a whole, the production of rambutan requires a significant amount of care and attention, but the delicious and nutritious fruit is well worth the effort.
