An unknown vegetable world !

Can we imagine tropical cultural products sold on a national market finding a sustainable demand in foreign countries while they are unknown by Western people ?


In the way, European countries demand more and more a diversified food, new tastes, original and rare products, that strange to see that so many exotic fruits knowdifficulties to be commercialysed in Northern countries. That's why we select tropical productions which are developing in Southern countries ,where they grow, but that a european consumer has never heard about it. This is in order to inform you on what is grown on the other side of the ocean, and to make you dream through very exotical pictures....

Star Fruit

Averrhoa Carambola



Synonyms : Carambole (French), Carambola (Spanish), Ma Fueng (Thaïland), Fuang (Laos), Khe (Vietnam), Belimbing (Malaysia)


Origin : The origin of the fruitis unknown, but it is probably native to Malaysia, Indonesia and India. Some people claim that it is originated of Moluccas.



Area of Culture : Despite its Asiatic origin, the fruit spreads out in the world. It is domesticated in the American tropics (Hawaï, Florida, Brazil..), in Australia. Its commercial production now occurs throughout tropical regions of the world and it is exported in Europe. Malaysia is the global leader of the star fruit production in the world.



Description : The star fruit is a slow-growing tree: it remains a shrub during a long time and it becomes very tall reaching more than two meters in height.






Flowers appear in groups at the pit between the leaves and the stem or at the branch apex. They are of pink colour. The blooming begins between November and December and the flowers follow one another until May.




The fruit is composed of 5 to 6 salient fins. The star shaped cross section gives to the Carambola its common name of Star fruit as well as it colour : translucent yellow.




When you cut the fruit in slices, you can have much as star shaped slices as you want to.
The light-brown seeds are flattened and not numerous.



Climate conditions : The star fruit is a tropical and subtropical fruit. The Star fruit is best grown in warm regions from sea level to 2000 feet high. The fruit stops growing below temperatures of 55-60F and older trees can be killed when they are exposed a long time to temperatures below 28F. The fuit needs to be protected from extreme cold. However, older trees are more tolerant to frost.
The Star fruit needs also a shaded place at the beginning of its growth.


Cultural method : The Star fruit prefers full sun but it also requires enough humidity (rainfall). It does not have a preference in the type of soils (quality) but it requires a good drainage.

The Carambolas need to be planted at least 20 feet far away from each other. You have to fertilize the plants four to five times a year and to give regular and moderate amount of water throughout the year. The fruiting period is situated during the months of June, July and August but in some regions of the world, you can have a n all year fruitung period. The first fruits appear at 4 to 5 years of age.


A Carambola is ripe when the fruit shows colours of yellow with a lightshade of green. At the contrary, an unripe fruit is green and an overripe fruit is yellow with brown spots on it.



Uses : Fruits are generally eaten raw, but occasionally they can be used in desserts or juices. The best way to consume a Carambola, it is when it is ripe. The fruit is entirely an edible fruit, incluiding the skin.


Because of the fruit star shape, the fruit is also used as an adornment.

Mangosteen



Garcinia Mangostana L.


Synonyms : Mangostan


Origin : The place of origin of the mangosteen is unknown but it might be the Sunda Islands and the Moluccas in Malaysia.



Area of culture : The area of culture of the mangosteen is stretching from the South of the Philippines to South India, but it is cultivated primilary in Thaïland, Vietnam, Singapore, Malaysia, Burma, Hawaï.. : the most in Indonesia and South of the peninsula indochinese.

Description : The mangosteen tree is growing slowly, reaching from 20 to 80 feet in height with a pyramidal crown. The evergreen, elliptic and opposite leaves present two colours: the upper side of the leaf is green and bright; while the lower side is yellow-green and matted.


Flowers appear solitary or in pairs at the branch apex. They are composed of four pink petals with white shade in the middle and four persistent green sepals.

The fruit is round but lightly flattened at both ends. Mangosteen fruit is surrounded by a thick and smooth rind. When the fruit is ripe, the rind passes from yellow-green to red-purple. It contains from 6 to 8 white fruit segments: arils of the seeds.
We remove all the segments as we do for an orange. Mangosteen fruit is known for its aromatic and sweet flesh taste !

Climate conditions : The mangosteen is a strict tropical fruit. As a consequence, it requires high temperatures and a high amount of rainfall through its growing (high atmospheric humidity). It needs an annual rainfall of at least 1500 mm well shared through the growing period of the fruit : it tolerates only brief periods of drought. This water stress will induce blooming. The optimals temperatures for growing are situated between 25 and 30°C : the plant cannot tolerates temperature below 4°C and above 37°C. Mangosteen generally grows from sea level to 1,50 meters high.



Cultural method : The tree needs rich organic soil, and especially sandy soil. Mangosteen is usually propagated by "seeds". The so-called "seeds" are not true seeds because they developed without pollinisation: sexual intervention by pollen.
The capacity to germinate for the seed is lost quickly when the seed is separated from the fruit. As a consequence, seeds need to be sowed fresh and quickly. Procede by stem cuttings is difficult to realize because we have to do it in a water saturated environment.
It is recommended to have a place of around 12 meters for each seed. Planting is preferably done at the beginning of the humid season.
Plants need 50-75% of shade for the first 3 to 5 years: culture using the association of mangosteen trees and banana trees is a good solution !
With a good care, the trees will begin to produce fruits from 6 to 8 years after planting. Young trees produce around 100 to 200 fruits per year and mature trees produce from 500 to 1000 fruits per year (or more).



Uses : Mangosteen is primilary eaten raw but it can also be canned and used to make juices, jams or jellies.

Cape Goosberry

Physalis peruviana



Synonyms : Uvilla, Ground-cherry, Golden berry, Physalis, Aguaymanto, Inca berry, Poc-Poc [....].



Origin : Native to high altitude tropical lands in South America. More precisely, Physalis is native to Andean region of Venezuela (between 800 and 3000 meters high). However, fruits were cultivated in South Africa, in the region of the Cape of Good Hope during the 1800s: it is presumably the origin of its common name, Cape goosberry.



Area of Culture : After the cultivation of these fruits in the Cape of Good Hope, they developed in Australia. Now, Cape goosberries have spread to a large scale in the world and have naturalized in tropical regions around the world.


Description : Physalis is a perennial plant reaching from 1 to 2 feet in height: it is usually small, like tomato plant. The plant has green hairy leaves. The yellow flower is hermaphrodite. The fruit is a small round berry about the size of a marble with a lot of small yellow seeds in it. The colour of the ripe fruit is yellow or orange. The fruit is surrounded by a calyx: a kind of pod which looks like a lantern.





Climate conditions : Cape goosberry grows best in tropical areas with not quite hot temperatures (warm temperatures). The plant needs also to be covered from frost because the aerial part of the plant is nipping at (- 3°C). Howling winds can damage or kill the plant.




Cultural method : Plants are propagated by seeds or by stem cuttings. Physalis can grow in most soil types. It can accept very poor soils to grow and also to be cultivated in pots. However, Cape goosberry feared misdrained soils and suffocating one. Densities of population do not exceed 6500 to 11000 plants per hectare. We have to provide lots of water thoughout the growing period of time except when the fruit begins to ripe. Physalis can be cultivated as an annual or as a biennial plant.




Uses : The fruit is commonly eaten raw but it can also be used in jams, jellies or pies [....]. It is also popular to find cape goosberries in a restaurant used as a garnishment for a table or a dish because of their appearances with husks. In South America, fruits are also used in medicine because of their diuretic properties.

Dragon Fruit

Hylocereus undatus


Synonyms : Pita(ha)ya (Spanish), Belle of the Night (English)


Origin : The exact origin is unknown and undated but the plant might come from an area situated between Mexico (Central America) and South America.



Area of Culture : Now, dragon fruit is widespread: it is cultivated around the world in tropical areas. You can find it mostly in Southeast Asia, Australia and South America.




Description : Pitahaya is a succulent and vining or creeping plant with green steems reaching from 6 to 12 feet long. The plant climbs onto trees using aerial roots. They propaged by seeds or by stem cuttings.





Flowers are beautiful and some species are used as ornementals. They bloom only at night and one time. Flowers are called "Moonflower" or "Belle of the night". Blossoms are grouped together: 4 to 6 blossoms could succeed between December and April. These flowering cycles are leading to 4-6 fruiting cycles per year. As a consequence, you can find on the same plant at this period of time, buds, young fruits and mature fruits. Pollinisation is necessary to set fruit.


Dragon fruits will be harvest around one month later pollinisation. They can weigh from 150-700g each. Some fruits reach 1kg.


They are three types of dragon fruits:



- Hylocereus undatus (Red Pitaya) with red skin and white flesh composed of a lot of small black seeds. The most commonly known as "Dragon fruit".


- Hylocereus costaricensis with red skin and red flesh composed also of a lot of small black seeds.


- Hylocereus megalanthus (Yellox Pitaya) with yellow skin and white flesh composed also of a lot of small black seeds.


Climatic conditions : Dragon fruit grows best in dry tropical areas with a moderate amount of rain. The annual rainfall may be situated between 600 to 1300 mm per year with an alternation of humid and dry seasons. The first summery rains begin blooming period. The plant tolerates high temperatures (38-40°C) and short period of frost otherwise the plant will be damage or kill.

Cultural methods : Because of their epiphytic nature, plants are not much depending on soil types. It is recommended to grow them in soil that is supplemented with a high amount of organic materials. The plants also grow successfully in sandy soils. Attention needs to be paid to the plants because of their environment. A specie of ant Solenospsis germinata cause important damages to the plants and particularly to the fruits and steems. The bites caused seem to be a good entrance for other diseases for Pitaya. Birds can also be a nuisance for the plant. Overwatering or excessive rainfall can cause the flowers to simply drop off and rot. A specie of bacteria can also cause steems to rot.




Uses : The only part of the fruit which is edible is the flesh: the skin is not eaten. It is recommended and very popular that dragon fruit is eaten chilled and alone to improve flavour. The fruit is low in calories. Eating fruit is likened to kiwi fruit. The fruit can be also converted into juice or used to flavour other drinks (tea..). Unopened flowerbuds are cooked and eaten as vegetables.

Prickly Pears

Opuntia ficus indica



Origin: This fruit comes from Mexico.



Culture of area: It's cultivated in Mexico and in Mediterrannean Bassin


Description: Prickly Pears grow on a cactus with hase leaves with spine on it, called "raquettes". Flowers are bright yellow and frits are around 6 cm large and crimson. Fruits are very sweeted and riched with vitamine C.





Climate conditions: This plant need a hot and drought climate. It's well adapted to arid lands. It tolerates light frosts.



Culturals Methods: Each plant needs 3 m2 to grow so that aroud 1100 plants per hectares. In average, yields can be 10 or 15 t/ hec. But culture with an adapted irrigation( not a lot) and fertilisation, plant's growth is accelerated and fruits are bigger.
From the fouth year, when cactus is productive, some farmers take flowers from the first bloom off, to have a better and bigger fruits issued from the second bloom.
Harvest made by hand is difficult because of spine.






Use:

Fresh Fruit: The first use of this plant is for her fresh fruits. Indeed Prickly Pears enjoy the exotic fruit market's growth in Europe and in USA. So everything is done to go towards an industialised production as irigation drop by drop and fertilization. This way, 50000 hec are cultivated in Mexico, 1000 hec in Italia and also in Israel.
This culture is profitable because it demands less investisments than cereals and prices are more interstants. Fruits know a better sucess when varieties without spines would developed.


Vegtable : Young "raquettes" thanks to their gustative quality find a new market the USA. They are eaten as a vegetable. That why an industry based on it developing in Mexico. They export 2000/3000 tonnes of these young "raquettes" on 23000 tonnes to the USA.


Forage: Raquettes are also used as forage. They give very good yields, around 30t of dry matter. It's use especially in Northern Africa (Algeria, Maroco...)


Beekeeping: With this culture it's possible to have a beekeeping activity during 3 months in the year. Bees can produce 1 or 4 liters of honey in a beehive. That's a sizeable income.



Medicinal properties: Flowers owns" anti-diurétique" substances. Fruit is a very good "antidiarrhéique" and it can reduce the cholesterol rate and the sensibility to insulin.



Industrial uses: In Chili a sirup is extracted from this fruit.

Biogaz is made thanks to leaves' fermentation.

Prickly pears are also grown because an insect called Cocus cacti lives in it. "Cochenilles" are used to make the only natural red colouring agent authorized in France, the carmitic acid.France import 20 tonnes a year of this colouring agent.



Ecological interests: It's use as fences in Algeriafor cattlle.
This vegetal which can easily grows in desert let to fix the sandy soil in Somalia and so it has fantastic results against erosion.

Durian or Civet fruit

Durio Zibethinus



Synonyms : Durion/Dourian (French), Thurian (Thaïland).


Introduction to Durian : The Durian is the fruit of trees from the genius Durio, composed of 30 species native to Southeast Asia. Only nine of them produce edible fruit. However, some unknown species which have never been discovered, studied or collected could produce edible fruits. We have decided to study the specie Durio Zibethinus because it is the only one available in the international market. It is the only specie commercially cultivated on a large scale and available outside of its native region. Others are commercialised but in their local markets of the regions where they are cultivated.


Origin : The Durian is native to Malaysia and Borneo. The name of Durian comes from Malay language "duri", meaning thorn.


Area of culture : Now, the fruit is cultivated in the major part of Southeast Asia. The main producers of the Durian fruit are : Indonesia, Malaysia and Thaïland. Thailand is not the native place of Durian but Thaïland is currently the major exporter of Durian : 781 000 tonnes per year.


It is known in Asia as the " KING OF FRUIT" !




Description : Durian trees are relatively large and can grow up to 30-40 meters depending to the species. Branches are strong and horizontal. Leaves are evergreen, dark green and elliptic. The lower side of the leaves is covered by a silver fuzz.





The flowers are produced by groups of 3 to 30 on adult branches and directly on the trunk. They are composed of 3 to 6 petals. The coulour of the flowers is yellow-white.




The Durian fruit is distinctive from the others by its large size from 20cm to 30cm long and 15cm in diameter. As an illustration of its large size, you hav to know that the Durian fruit is 5 to 6 times higher than a mango. His weigh can afford more than 5kg. His shape vary from round to oblong.
His particularity excepted his large size comes from its strange looking : a thorn,woody, covered of husks of one centimeter.

When the fruit is reaching ripeness, the colour of his husk becomes yellow/green to brown depending to the species, and his flesh pale yellow to red. Ripe fruit emits also a unique odour, strong and penetrating when the husk is intact. This odour is considered as offensive by some people and some compared it to "milk which had gone off". Some people have compared the odour to the one of rotting onions or unwashed socks or smell feet..
The disagreable odour has led to the fruit banishment from certain public transportation in Southeast Asia !


Quote about the odour of the Durian fruit by Richard Streling :
"... its odor is best described as pig-shit, turpentine and onions, garnished with a gym sock. It can be smelled from yards away. Despite its great local popularity, the raw fruit is forbidden from some establishments such as hotels, subways and airports, including public transportation in Southeast Asia."


From a biologist side, the fruit splits in 4 to 5 compartiments and each room contained one to six seeds surrounded by a flesh, odourless, edible and creamy. The colour of this pulp is between white and yellowish.



Climate conditions/cultural methods : Durian trees have one or two blooming and fruiting periods per year, thought the timing depends on the species, cultivars and localities. It is a seasonal fruit, it means that he is not available throughout the year. The Durian season is May throughout October.


The Durian fruit is a strictly tropical fruit : it stops growing up when the temperature drops below 22°C. Durian is cultivated in some regions of low altitude, until 700m and also in humid regions. Soil have to be deep.

The Durian is ready to harvest when it begins to crack.


Uses : Most commonly, the Durian fruit is eaten raw. In Southeast Asia, the flesh is also used to prepare ice cream. Fruits are consumed as good as ripe, fermented, dried or transformed in pastry. The Durian fruit considered as aphrodisiac is used against a lot of diseases. The legend says : "When the durians come down from the trees, the sarongs come off".
