Jackfruit

The jackfruit is a very big fruit.

It grows on a tree with a short trunk. The tree has thick, green leaves.

The fruit grows on the tree's branches and trunk. It has a hard shell. Inside, the fruit is sweet. It can taste like banana or pineapple. People eat the sweet parts. They also eat the seeds when they are cooked. It is a very useful fruit.

The jackfruit is the largest fruit that grows on a tree.

It grows on an evergreen tree. This means the tree stays green all year. The tree has a short trunk and thick leaves.

The fruit is a multiple fruit. This means it is made of hundreds or even thousands of tiny flowers that grow together.

Jackfruit trees grow well in warm, tropical places. They can produce many fruits in one year. Some old trees grow up to 500 fruits! The fruit has a hard, bumpy shell. Inside, there are many sweet parts called arils. These parts can taste like pineapple or banana. People use ripe jackfruit to make desserts. They also use unripe jackfruit in cooking. Some people say the young fruit feels like meat. You can even eat the seeds after you cook them. They can taste like chestnuts or Brazil nuts.

In some places, the fruit is used to make noodles or chips.

The jackfruit is a very special kind of fruit. It is the largest fruit that grows on a tree.

These fruits can be quite huge in weight and size. A single jackfruit tree can produce many fruits each year. Younger trees might grow about 200 fruits in one year. Older, larger trees can grow up to 500 fruits!

This fruit is what scientists call a multiple fruit. This means it is made of hundreds or even thousands of tiny flowers that grow together into one big piece.

Growing a jackfruit is a step-by-step way of nature. First, the tree grows small flowers on its trunk or branches. These trees have both male and female flowers on the same plant. The male flowers have tiny grains of pollen to help the fruit grow. Small bees, like the stingless variety, help move this pollen around.

Next, the female flowers grow into a large, bumpy fruit. The fruit starts out yellowish-green and slowly turns yellow or brown as it gets ripe. Inside the hard shell, many small, sweet parts called arils grow around the seeds.

People have known about the jackfruit for a very long time. The name comes from a word used by Portuguese explorers. They arrived in India at a place called Calicut in 1499. Later, a man named Garcia de Orta wrote about the fruit in 1563. He was a doctor and a scientist. Another person named Hendrik van Rheede wrote about it in the 1600s. Some people think the name might even come from a Scottish botanist named William Jack.

Jackfruit grows in many warm, tropical parts of the world. You can find these trees in South Asia and Southeast Asia. They also grow in places like Oceania and Brazil.

In 2017, India grew the most jackfruit in the world. Other big producers include Bangladesh, Thailand, and Indonesia. The fruit is very useful for many people. It can help provide enough food in some developing countries. It is also sold in many places as canned, frozen, or dried.

There are so many ways to eat this fruit. When the fruit is ripe, it tastes sweet like pineapple or banana.

People use it to make tasty desserts like cakes or ice cream. You can even eat the seeds if you cook them first. Cooked seeds can taste like chestnuts or Brazil nuts. When the fruit is still young and green, it has a different use. It has a texture that feels a bit like meat.

Because of this, people use it to make vegan burgers or pulled pork dishes.

The jackfruit, known scientifically as Artocarpus heterophyllus, is a remarkable species of tree. It belongs to the Moraceae family, which includes figs, mulberries, and breadfruit.

This tree is famous for producing the largest tree-borne fruit in the world. These massive fruits can reach incredible sizes in length, diameter, and weight. A single mature tree is highly productive. It can produce about 200 fruits every year. Older, more established trees can bear as many as 500 fruits annually. Because of its high yield, the jackfruit is a vital resource for food security in many developing countries.

Understanding how a jackfruit forms requires looking at its unique structure. The jackfruit is a multiple fruit. This means it is not just one single flower, but a fusion of hundreds or even thousands of individual flowers.

These flowers grow through a process called cauliflory, meaning they develop directly on the trunk, branches, or twigs. The tree is monoecious, which means it carries both male and female flowers on the same plant. The male flowers are greenish and hairy, containing tiny pollen grains about 60 microns in diameter. The female flowers have a fleshy base and contain an ovary. After pollination, these many ovaries fuse together to create the large, single fruit we recognize.

The jackfruit tree itself has very specific physical characteristics. It is an evergreen tree with a relatively short trunk and a dense treetop. The trunk can reach heights of 20 meters, and the diameter can reach 1 meter.

The bark is reddish-brown and smooth to the touch. If the bark is injured, the tree releases a thick, milky sap. The leaves are thick, leathery, and gummy. They are arranged spirally on the branches. On older trees, the leaf blades are dark green and rounded with smooth edges. Each leaf has a prominent main nerve and six to eight lateral nerves extending from the sides.

History shows that the jackfruit has been a part of many cultures for centuries. The name "jackfruit" likely has Portuguese origins. It may stem from the Malayalam word "chakka." This connection traces back to 1499, when the Portuguese Empire arrived at Calicut on the Malabar Coast in India.

In 1563, the physician Garcia de Orta recorded the fruit in his writings. Later, Hendrik van Rheede documented it in the 1600s. Some historians, including botanist Ralph Randles Stewart, suggested the name might honor William Jack. He was a Scottish botanist who worked in Bengal, Sumatra, and Malaya during the early 1800s.

Cultivation and ecology play huge roles in how the jackfruit spreads. The tree thrives in tropical lowlands, particularly from South Asia to Southeast Asia and Oceania.

In some areas, like Brazil, the jackfruit has become an invasive species. This happens because small mammals like the common marmoset and coati eat the fallen fruit. These animals then disperse the seeds, allowing the trees to compete with native species. Pollination is also a complex process. Stingless bees are important pollinators. There is also a suspected three-way mutualism involving the flower, a specific fungus, and a species of gall midge.

The fruit itself is composed of several distinct parts. The exterior is a hard, gummy shell covered in small, hexagonal tubercles. Inside, there is a fibrous, whitish core called a rachis. Radiating from this core are many individual fruitlets. Each fruitlet contains a seed protected by a fleshy, sweet layer called an aril. An average fruit is made of 27% edible seed coat, 15% edible seeds, 20% white pulp, and 10% core. The ripe fruit has a strong aroma that smells like a mix of pineapple and banana. This scent comes from specific chemical compounds like ethyl isovalerate.

People use every part of the jackfruit in different ways. When the fruit is ripe, the sweet arils are used in desserts, cakes, or even ice cream. In Indonesia, it is used in treats like es teler.

The seeds are also edible once they are boiled, baked, or roasted. They can taste similar to chestnuts or Brazil nuts. When the fruit is unripe, it is often called "vegetable meat." This is because its mild taste and meaty texture make it a popular choice for vegan dishes.

It is commonly used in South and Southeast Asian cuisines to create meat-like textures in various meals.
