Rambutan: features, properties and tips for eating
Kiwi and avocado have already ceased to be absolute exotic in Russia. But gradually new fruits are coming, which are not yet familiar enough to people. One of them is rambutan, which we will talk about in more detail.
What it is?
Rambutan literally means "hairy" in Malay. This name exactly matches the appearance of an exotic fruit. It grows on an evergreen tree. The fruit itself has a jelly-like texture. So far, rambutan is practically not exported from Malaysia, so the chances of trying it anywhere except Southeast Asia tend to zero.
The plant has another name - nephelium. The fruit is usually bright red, occasionally crimson. Rambutans grow in bunches. If you cut off the peel, you will find a translucent, pearl-colored flesh. However, it can only be called pulp conditionally - the difference between rambutan and lychee is just related to the hardness of the core.
The taste of the fruit is sweeter than that of the lychee. It is not difficult to notice, however, a slight sour note. Ripe fruits are always juicy, contain quite a lot of seeds. You can peel rambutan without a knife or some other sharp object. Although the fruit looks like it is covered with spines, the hairs are by no means stiff, they are easily bent.
Those who have tasted rambutan note that it feels like grapes.And this feeling is not accidental. Malay fruit also helps to compensate for the lack of moisture. The thick skin keeps the inside of the fruit free from contamination. This property is very valuable for tourists who do not want to risk being away from running water.
How and where does it grow?
An exotic tree can reach 25 m in height. It forms a spreading crown. Rambutan is found in almost all states of the tropical belt. It grows even in Australia. However, the leading position in the international market is occupied by Thailand. It should be noted that rambutan reaches a height of 25 m only in favorable conditions. Usually it is limited to 6-7 m. Many branches develop on the tree. The fruits outwardly resemble chestnuts or walnuts, the shape is a circle or oval. The largest size of the fruit does not exceed 6 cm.
The rind of rambutan is relatively dense, and when the fruit ripens, the coloring only becomes more saturated. Fruit is harvested in the tropics in July and December. Breeders managed to breed up to 200 varieties that have fruits of various sizes and colors. The main direction in breeding work is to reduce the height of the tree - so far it has been possible to reduce it to 4 m. A number of varieties have been bred, the fruits of which do not contain seeds, however, it is worth noting that the taste of seedless rambutan necessarily becomes sourer.
Taste and composition
The pleasant taste of rambutan is not its only advantage. The pulp of the fruit contains many vitamins, especially ascorbic acid. Also, the Malay fruit is rich in B vitamins. The concentration of mineral components is also high:
- copper;
- calcium;
- potassium;
- zinc.
In addition to these components, rambutan contains a lot of magnesium. Up to 100 mg can fall on 1 fetus.Yes, to fill the daily requirement, you have to eat quite a lot of fruit. But in hot, sultry weather, this happens by itself. Good rambutan and high concentration of iron.
The pulp of the fruit is quite rich in phosphorus. 4.3% of the daily value per 100 g of the product. There are 2 g of fiber per 100 g of product. At the same time, the same mass of pulp contains no more than 60 kcal. Low calorie content, together with high fiber and water content, make rambutan recommended for weight loss.
The properties of the fruit make it a useful element of low-calorie diets. Successfully suppressing hunger helps prevent relapses. According to experts, rambutan seeds also give a good effect in losing weight. It is best to swallow them crushed, in combination with other foods. Raw seeds can be consumed only in extremely small quantities.
Benefit and harm
The beneficial properties of rambutan have been actively used in traditional medicine in Southeast Asia for hundreds of years. Centuries-old experience, together with the results of biochemical studies, allows us to confidently say that this plant helps:
- patients with diabetes;
- suffering from high blood pressure;
- people with impaired immunity.
There are benefits in the fight against parasites, as well as a reduction in the risk of cancer. In the past, Thai medicine men used almost all parts of the plant. They even used roots. One of the latest studies by Malay experts showed that inedible parts of rambutan can be useful in the fight against already developed cancer. Such an effect was found in seeds, fruits and peels - and, importantly, a positive result is achieved with a variety of types of tumors.
The high concentration of antioxidants in the peel helps to slow down the aging process. Not without reason, specialized companies and online stores are increasingly beginning to supply an extract from the peel of the Malay fruit. But the beneficial properties of the rambutan shell do not end there. The gallic acid contained in it successfully suppresses microorganisms. Even if they have already attacked the cells of the human body, this substance acts in the most gentle way, without aggravating the damage.
According to recent studies, gallic acid, together with other substances contained in the fetus, effectively fights microbes, viruses, and even pathological fungi. The presence of phosphorus facilitates the excretion of various waste products by the kidneys. This trace element also contributes to the restoration of damaged organs and tissues. And if they are completely intact and healthy, phosphorus will help prolong this situation. There is evidence, although not fully confirmed, that ingestion of rambutan seeds improves the condition of diabetics.
Hairy fruit contains a lot of carbohydrates and proteins. This combination provides an almost instant energy boost. And if you take into account the juicy pulp, this fruit can be safely recommended for those involved in sports and physical education. Due to the presence of copper, rambutan helps to improve blood formation. And this function of the body is equally valuable for those engaged in physical and intellectual labor.
A significant amount of manganese allows you to increase the production of enzymes and increase their activity. Thanks to this, the biochemical processes in the body will go faster, become more complete. The combination of phosphorus, calcium and iron helps to strengthen the musculoskeletal tissue.As a result, the risk of a fracture is reduced, and if it does occur, recovery is accelerated and facilitated.
Rambutan enhances the peristalsis of the final sections of the gastrointestinal tract. Therefore, the risk of constipation is reduced. But it is precisely with this circumstance that the main contraindication of a tropical fruit is connected. It is not recommended for those suffering from diarrhea, including those who have undergone food poisoning. The systematic use of rambutan improves the condition of the skin, and even masks for rejuvenation are made on its basis.
The bones of the Malay fruit are used to produce a unique oil. This natural liquid is in demand in the manufacture of cosmetics, shampoo and even soap. It is noted that rambutan oil inhibits hair development. That is why it is appreciated by those who often do hair removal. It should be noted that a day you can eat no more than 8 fruits. This is the maximum amount that only perfectly healthy people can afford.
If there are at least minor health problems, it is worth bringing the daily portion to a maximum of 5 rambutans. It is recommended to avoid the consumption of uncooked seeds. Otherwise, they turn out to be bitter, and even contain substances with a narcotic effect. Toxins are also concentrated in the peel, so it, like the seeds, should be used carefully.
How is it eaten?
To eat the fruit of rambutan, you must be able to properly clean it. You can make an incision in the peel with a knife and carefully remove it. But often they do without any knife, just pressing on the surface. One side cracks, after which it is possible to extract the fruit. You can throw away the bone, and that's what most people do.
But it is much more correct to do it, as is customary in Asian countries.There, these bones are fried and eaten. As for the storage of the Malay fruits themselves, even in the refrigerator they will lie for a maximum of 7 days. Despite the benefits of raw rambutans, they are often used for:
- jam processing;
- jam cooking;
- making sauces.
Alternatively, the pulp can be preserved with sugar. Rambutan fruits are used as an integral part of a number of exotic dishes, including desserts. Experienced chefs advise filling them with pies. Malay fruit gives great sensations in combination with ice cream. And you can also make an excellent compote from it.
How to choose and store the fruit?
The excellent quality of rambutan can only be enjoyed if it is chosen correctly. It is unacceptable to buy fruits, the peel of which has spots, especially dents or scratches. Almost always brown fruits are stale. A quality product is distinguished by the greenish tone of the hairs. If they have lost elasticity, you should also refuse to buy.
When rambutan is transported or stored at temperatures around 0 degrees, it becomes darker and loses its taste. The recommended temperature is 7-15 degrees Celsius. In this mode, the fruit can be stored for up to 14 days. As already mentioned, you can choose either varieties with or without a stone, but more acidic. Knowing these simple rules, you can choose guaranteed high-quality rambutan.
Growing at home
In order not to choose fruits, while still risking running into marriage or a low-quality product, you can grow rambutan at home. It is also cheaper than buying imported fruits. Given the tropical origin of the plant, it is necessary to maintain:
- intense light (at least 12 hours per day);
- air temperature of at least 18 degrees Celsius;
- high humidity in the room.
Residents of the southern regions of Russia can take a chance and try to grow a "tropical guest" in the open air. For this purpose, only areas reliably covered from the wind are suitable. There must be fertile land, built of clay or loam. Good drainage is also essential. At the same time, in most of Russia, rambutan can be cultivated only at home.
A tree grown in a pot almost always has only a decorative function. But with luck, you can achieve fruits in season 5. Beginning gardeners are advised to grow rambutan from the seed, as this is the easiest option. It still needs careful maintenance though. The first step is to buy at least a few ripe fruits from the tree.
Bones are pulled out of them, at least one should sprout. But we must remember that the germination of seeds does not last long. It is best if the landing is made immediately. It is advisable to check the quality of planting material in order to avoid disappointment. To do this, the seeds are separated from each other:
- wrapped in damp cloth;
- transferred to a sealed container;
- transferred to heat.
It is necessary to constantly monitor so that the fabric does not dry out. Treatment with growth-stimulating drugs helps to increase the chances of success. In most cases, sprouts appear on the 10-15th day of such treatment. Sprouted seeds are immediately transplanted into a pot filled with soil mixture. Flower primer is recommended, 3 parts of which are mixed with 1 part of peat. It is advisable to lay out the bottom of the pot with drainage material:
- broken ceramics;
- expanded clay;
- pebbles of a large fraction.
The bones are laid 2-3 cm into the ground. The container must be covered with glass or polycarbonate to achieve a greenhouse effect.She is moved to a warm sunny place. Watering is carried out, focusing on the dryness of the coma of the earth. Normally, the sprout comes out after 7-8 days, but sometimes you have to wait longer. After about 60 days, rambutan grows to 3-4 cm and gives the first foliage.
A stronger shoot is transplanted into a larger tank. If the weather is warm, you can put the plant on a balcony or terrace, but on condition that it is sunny there and the air is stably warmed up to 25 degrees. An exotic tree does not survive temperature fluctuations well. If the air cools to +10 degrees, it may die altogether. Water the seedling systematically - and at the same time avoid waterlogging.
The accumulation of excess water in the pan leads to deformation of the rambutan roots and threatens the appearance of fungal diseases. Yellowing of the foliage and stunting show that the tree lacks moisture. If it is not possible to transplant the plant, you need to replace the upper part of the soil in the tank at least once every 6 months and add humus. Strict observance of these rules allows you to enjoy the pleasant appearance of the tree in the next few years. Rambutan survives pruning well - therefore, you can improve its appearance yourself.
