Fruits, bark, seeds, roots.
The cempedak fruit is very rich in vitamin A, which plays many roles in the body. One of the most important ones is to protect the eye cornea and improve vision. It is also a major source of dietary fiber, very good for digestion. Some compounds found in the bark can cure malaria and maybe even fight cancer. Vitamin A can be found in other vegetal sources but the cempedak fruit is one of the most delicious, so it can be a very enjoyable way to get your supply of this essential vitamin. Vitamin A is a very powerful antioxidant that plays a key role in the immune system but is especially known for improving vision. The cempedak is very good for the heart, due to the ideal mix of fibers, vitamin C and other antioxidant compounds. The fruit includes a lot of potassium, which also helps circulation and regulates high blood pressure. By alleviating hypertension and reducing cholesterol in the blood, eating this fruit contributes to overall cardiac health. A decoction prepared using the roots of cempedak has been used in traditional medicine to treat a variety of diseases like asthma, stomach disorders, and fever or skin problems. The plant is known to kill viruses, bacteria and fungus, a very useful effect in the treatment of infections of the urinary tract. It has a positive effect on a number of conditions, such as high blood pressure, anxiety and arthritis. The combination of antioxidants in the cempedak fruit can improve the condition of the skin and maintain the health of its cells. Malaria is one of the most dangerous diseases in the tropical areas where the tree grows. Eating the fruit in any form is said to cure malaria, probably due to the combination of vitamins with enzymes and bioactive components like bioflavonoid. The fruit is also capable of killing various internal parasites. These are a serious menace in rainforest areas and can severely impair the function of body organs. In time, parasites cause many dangerous diseases. Bioflavonoids are a type of very strong antioxidants that can neutralize the free radicals that are a by-product of our metabolism. This greatly improves the immune response to external threats. Cempedak is also very good for digestion, like many other fruits. This is because of the content of soluble fibers and vitamin C, which regulate bowel movements and prevent constipation. The fruit also greatly reduces the risk of heart attack, due to a combination of essential vitamins and nutrients. Strokes are one of the worst health hazards of today's society. Cempedak is generally recommended in weight loss diets because it gives a sense of fullness after a meal, eliminating the need for small snacks in between. The tree is a source of good quality wood. Since it is very strong, it serves in the construction of boats or in various home improvements. It can also be used to prepare a good quality yellow dye. The fibers in the bark are useful in manufacturing rope.
Cempedak is consumed in large quantities in its native range in Asia and it's starting to become popular in Australia as well. It is delicious if eaten raw but it can also be prepared in various ways. A popular street food in Malaysia is cempedak fried in oil, after soaking the pieces in batter. The seeds resemble the taste of water chestnuts and can be eaten raw after peeling but also roasted or boiled. Immature fruits can be eaten just like green vegetables. A special dish is prepared in the island of Borneo from the skin of the fruit. It is called mandai or dami and is prepared after peeling the cempedak until it becomes white. It is then placed in a solution of salt, which can preserve it for a long time and makes the flesh tender. It can be stored for a month, or prepared after a few hours. Mandai is prepared by taking the fruit out of the brine and frying it.
For best results, the tree should be planted in direct sunlight. It can also grow in shade, but the rate of development will be a lot slower. It also requires constant moisture and irrigation is necessary in dry areas. It is completely absent in nature from regions that have a dry season. The minimum amount of annual rainfall required by the tree is about 1,250 mm. While the tree likes moisture, it will die if the roots stay underwater for 4 hours or more. For this reason, cempedak requires very good drainage and will grow very well in sandy loam soils in particular. For propagation, the seeds can be sowed directly into the ground. It is common to grow new plants in containers, then transfer them outside. It is also possible to propagate cempedak by budding or by grafting on rootstocks of other varieties of breadfruits.
When harvested unripe, the fruit can be eaten like a vegetable. Ripeness is estimated based on a series of factors, like the smoothness of the skin, variations if skin color or the stem turning yellow. However, it is also possible to just let the fruit fall off from the tree. In this case, it must be consumed quickly, in maximum 2 or 3 days.
