The baobab, also called the upside down tree, could turn around the drinks industry. Dr John Wilkinson and  Dr Matt Hall explore the benefits of baobab.

While there is possibly 100,000 different edible plants in the world, so few are commercialised due to incomplete safety assessments, poor shelf life and the unavailability of the material for commercial production.

Recently a new botanical to the West seems to have found a reasonable solution to these problems with its use being imminent into the EU and the USA market place (Wilkinson 2006).

The baobab tree, Adansonia digitata, is a member of the Bombacaceae family which consists of around 20 genera and around 180 species (Heywood, 1993). This deciduous tree was originally located in South Africa, Botswana, Namibia, Mozambique and Zimbabwe (Keith & Palgrave, 2000), but can be found in most countries within the African continent. Export by traders means the baobab tree is also common in America, India, Sri Lanka, Malaysia, China, Jamaica and Holland (Sidibe & Williams, 2002).

The baobab tree has many names including the monkey bread tree, the cream of tartar tree, and the “upside down tree”. This last reference is due to the striking silhouette that the baobab tree forms at sunset which gives the appearance of the tree being uprooted and stood on end.

The heavy white flowers of the baobab tree are pollinated by fruit bats at night. The resulting large green or brownish fruits resemble gourd-like capsules that around 6-8 inches in length. These capsules contain a soft whitish fruit pulp that has the appearance of powdery bread and kidney shaped seeds. The baobab fruit is wild harvested by collecting from the trees or from the ground.

The hard shells of the fruit are cracked open and the powdery fruit pulp is separated from the seeds and shell before use. The resulting free flowing creamy white powder, melts in the mouth when sampled and has a unique pleasant flavour with a mild slightly acidic after taste which can easily be masked with sweeteners or other flavourings for incorporation into drink products.

Nutritional composition

Airan and Desai (1954) first highlighted the presence of organic acids in the baobab fruit pulp.

These included citric, tartaric, malic, succinic, and ascorbic acid. A later report from Nour et al (1980), confirmed the observations of Airan  and Desai when they showed that the pulp  contained ascorbic acid, tartaric acid, mainly water soluble pectins, and the elements of iron and calcium.

Nutritional analysis of baobab fruit pulp has shown that the fruit is an excellent source of pectins, calcium, vitamin C and iron. Vitamin C content of baobab fruit pulp has been compared with oranges by Manfredini et al (2002), and shown to be at least at least three times higher (150-499 mg/100g vs 46mg/100g). Nour et al (1980) reported that the vitamin C content of baobab fruit pulp was 300 mg/100g whereas data from Wilkinson (2006) shows vitamin levels ranging from 74 to 163 mg/100g. The current EC RDA value is given as 60 mg/day and so 10g of fruit pulp would give at least 25% the recommended daily amount of ascorbic acid.

Trace elements

Data from Kalenga
Sa ka et al (1994)

Data from Glew et al

Wilkinson (2006)























The baobab fruit pulp contains a high level of pectins, and has been found to contain up to 56% water soluble pectins by weight (Nour et al, 1980).

Recent analysis by Wilkinson (2006) revealed the pectin content to range from 23.4 to 33.8 g/100g of baobab fruit pulp. Although not as high as other reported values, these indigestible but soluble fibres are an important component of our diet.

Trace element analysis (see Table 1) shows that baobab fruit is a good source of calcium with 100g of baobab fruit providing 116 to 370 mg depending on the source (RDA for calcium is 500 mg/day). Iron content per 100g of fruit pulp is 1.7 to 9.1 mg (RDA for iron is 17 mg/day) and sodium content is very low.

Traditional food uses

The pulp of the baobab fruit is reported to have numerous uses by the indigenous people of Africa.  Bosch et al (2004) reported that the fruit is eaten as a sweet and used to make ice-cream. In Sudan, a refreshing drink called ‘gubdi’ is made from the fruit pulp and cold water to preserve the vitamins (Bosch et al, 2004). Amongst the Hausi farmers, the baobab fruit juice mixture is a popular drink and is available during the hot times of the year (Nicol, 1957).

The baobab fruit pulp is reported to be used in cooking, the dried pulp can be used in baking as alternative for cream of tartar (Bosch et al, 2004). Diop et al (1988) reported that the pulp was rich in calcium and this was the main reason that the baobab was largely consumed by pregnant women and children in Senegal. A study of pregnant women in Gambia, by Prentice et al (1993), reported that eating the fruit pulp in season  (December to April) without the seeds once a day, contributed 30 mg/day calcium to the diet.

Use of baobab in the EU and  the rest of the world

There are several reports in Europe of baobab fruit being used within the EU.  In the early 1900’s, there was a report that several tonnes were imported into the UK for use in the preparation of tea cakes (Kerauden, 1963). Later, during the First World War, the fruit pulp was used as a leaven for baking bread (Watt and Breyer-Brandwijk, 1962).

Unsurprisingly in Paris, the immigrant communities from West and central Africa, are reported to use the baobab in the traditional manner of their forebears. Most recently, an Italian media outlet reported that baobab fruit supplements have been endorsed by Italian cyclists, a Formula one driver, and AC Milan football players. There are numerous reports from across the globe regarding the use of baobab fruit pulp. In the USA dispensaries from 1860 to 1947, there are reports regarding use of baobab fruit (Woods et al, 1880, 1907, 1932, 1943). In Canada, baobab fruit was listed as a substance in cosmetics and care products between between January 1, 1987 and September 13, 2001. In India, the baobab tree is widely distributed and the fruit is regularly consumed. Finally, in Australia, fruit from Adansonia gregorii, a close relation of  Adansonia digitata, was considered by the Australian Food Standards agency as “not novel” and given food status in March 2005.

Traditional medicine use of baobab fruit

All parts of the baobab tree are reported to have medicinal properties according to traditional folklore (Watt and Breyer-Brandwijk 1962).

Of particular interest is the use of baobab fruit and seeds to treat dysentery as reported by Watt/Breyer-Brandwijk (1962). Recently, Tal-Dia et al (1997) compared the efficacy of a local solution, “pain de singe”, made from baobab fruit against the WHO standard solution for treatment of dehydration. The results showed that both solutions were equally effective.

Baobab fruit is reported to have febrifuge (antipyretic) properties in traditional medicine. Ramadan et al, (1994) showed that whilst baobab fruit pulp may lower elevated body temperature, normal body temperature is not affected.


Baobab dried fruit pulp is the latest novel food that could soon be available in the EU if regulatory approval is forthcoming. The intended use for baobab dried fruit pulp will mainly be in fruit bars and smoothies. Of more interest to manufacturers is the high nutritional value of the baobab dried fruit pulp which has been found to contain high levels of pectins, calcium, vitamin C and possibly iron.

There are very few new novel foods and exotic fruits that are now being introduced into the EU because of the high costs of getting approval as a food. Baobab is a land mark case in that if it is approved (the application by the baobab producers, PhytoTrade Africa was filed in June 2006), its approval will have been obtained by paying close attention to the real and justifiable concerns of the regulators, and finding innovative ways to achieve the safety objectives whilst avoiding inappropriate and unnecessary costs. Pending success with this approach, could inspire other exotic food producers in areas such as South America, Asia and Africa, to once again, bring new botanicals into the EU for consumers to enjoy without the millions of pounds of investment which has been needed in the past for novel foods to get approved.

Baobab powder is very nutritious. To obtain it, you can plant and grow your own baobab. We’ll explain you how to do it.


Baobab is the common name of a genus (Adansonia) with eightspecies of trees, 6 species in Madagascar; 1 in Africa and 1 in Australia.

  • Adansonia gregorii (A.gibbosa) or Australian Baobab (northwest Australia)
  • Adansonia madaf Zascariensis or Madagascar Baobab (Madagascar)
  • Adansonia perrieri or Perrier’s Baobab (North Madagascar)
  • Adansonia rubrostipa or Fony Baobab (Madagascar)
  • Adansonia suarezensis or Suarez Baobab Diego Suarez,(Madagascar)
  • Adansonia za or Za Baobab (Madagascar)

The name Adansonia honours Michel Adanson, the French naturalist and explorer who described A. digitata.

General Background

One of the earliest written references to the Baobab tree was made by the Arabic traveller, Al-Bakari in 1068. In 1592, the Venetian herbalist and physician, Prospero Alpino, reported a fruit in the markets of Cairo as “BU HUBAB”. It is believed that the name is derived from the Arabic word Bu Hibab which means fruit with many seeds.

Common names include bottle tree and monkey bread tree. Baobab – derived from African fokelore “upside-down-tree”. The story is after the creation each of the animals were given a tree to plant and the stupid hyena planted the baobab upside-down.

The baobab is the national tree of MadagascarWatering Baobabs.

Once the leaves start turning yellow at the beginning of autumn – gradually slow down watenng. Stop watering when plus minus 50% of leaves turn yellow. Do not water trees during the dormant (winter) period. However, some people do water in winter, mainly in hot areas, but according to experience chances are very good that trees will rot and may die.

Slowly start watering again when the trees are sprouting new buds, usually mid September.

Do not over water during this period but gradually increase water and fertiliser (preferably organic) as more and more leaves develop.Only once the tree is in full leaf can it receive as much water and fertiliser as other trees. Always let the surface soil dry out a bit before watering again. Adjust watering during rainy periods.

Where to keep Baobab

Baobabs like direct sunlight for as long as possible during the active growing period. The more sun the better they grow. Preferably keep under a hail net or not more than 30% shade net. Never keep indoors during growing period. During winter the tree MUST be kept anywhere indoors, on a wall unit or even under the bed or in a cupboard. The tree does not need any sunlight during the cold winter months as it is completely dormant. Protect the trees from cold (below 10 deg C) and frost – It is recommended keeping them indoors, this solves the problem of cold and frost and the temptation of watering them where they can also be displayed.

Transplanting Baobabs

Baobabs are easy to transplant as long as you stick to the basics. Baobabs can be transplanted from September to December. Baobabs have potato like roots – it is edible (some very sweet others not). Always make sure the cut through the root is done with a sharp tool and the cut is clean – the cut should at a right angle (90 degree) with the root to keep the surface of the scar as small as possible. Always seal the cut with a mix of wood glue and flowers of sulphur to prevent rotting of the root. Some bonsai growers burn the freshly cut root. Place the cut root after the application of the flower of sulphate mix in direct sunlight to dry out for about an hour. Transplant in a deep bonsai pot and make sure the tree is anchored if a lot of roots were removed. Do not water for 7 to 14 days, keep in full sun, thereafter water sparingly in the beginning until the tree is full of leaves. Baobabs prefer a well drained soil mixture. Soil mixture of 2 parts coarse aggregate, and one part compost.

Diseases in Baobab as Bonsai

Baobab trees have very few pests. Be careful of rootrot – too much water at the wrong time. Trees with root rot can be rescued if discovered early – cut back until there is no more sign of rot and treat the same as a newly transplanted tree. Regularly feel the base of the tree, it must remain hard because rotting always starts from the roots upwards. They may also be attacked by fungi.

Training Baobabs as Bonsai

To obtain the quickest results, the young seedlings should be transplanted in a big container. The bigger the better. The container should stand on the ground to give the roots the opportunity to grow through the enlarged drainage holes into the ground. Alternatively on top of another large pot filled with soil. This will result in very fast developing trees. The roots inside the pot must be watered to keep them alive. When the tree is transplanted the roots in the ground (larger pot) will be sacrificed and only the roots inside the growing pot will be used. The top growth needs to be trimmed back to compensate for the loss in roots. If planted to grow into open ground, in areas that are very cold and frost occurs during the winter months, the roots should be cut off just below the container and the cuts treated with flowers of sulphur.

All Baobab trees should be moved somewhere indoors to protect them from the cold.

This process should be repeated year after year until the desired development is reached.
