Baobab fruit

Adansonia digitata L. (Malvaceae) is a versatile tree native to the savannas of Africa, highly regarded for its medicinal and nutritional value. Locally, it is known as kuka in Hausa, yiri mango or igiose in Igbo, and ose in Yoruba. Commonly referred to as the baobab, monkey bread tree, upside down tree, cream of tartar tree, boab, bottle tree, and kremetart tree, Adansonia digitata thrives in the arid, semi-arid, and dry sub-humid regions of Nigeria. Remarkably, it is the only fruit in the world that naturally dries on the branch.

Constituents

Phytochemical analysis has revealed the presence of flavonoids and phytosterols. Additionally, it contains carbohydrates, crude protein, moisture, fibre, ash, and micronutrients such as calcium, iron, potassium, phosphorus, magnesium, thiamine, riboflavin, as well as vitamins A, E, and omega fatty acids. The plant is also rich in mucilage, pectins, tartarate, free tartaric acids, vitamin C, linoleic acid, oleic acid, and palmitic acid.

Preparations

Baobab is available in various forms, including seeds, pulp, leaves, and roots, either dried or fresh; these can be boiled or roasted. It is also offered as oil, powder, fruit, bark, porridge, sweets, and juice. Due to its high pectin content, the pulp has traditionally been used as a thickening agent for sauces and jams.

Economic uses and potentials

Baobab fruit powder costs approximately 4,100 per 200g in the Nigerian market. A 2008 report by the UK-based Natural Resources Institute estimated that trade in baobab fruit could be worth up to $961 million per year for African producers; it is currently valued at $11 million. The global market for baobab powder is expected to grow to $10 billion by 2027. African producers reportedly export approximately 20 tons of baobab each year. This growing industry is providing financial benefits to local people who harvest and process the fruit. The baobab plant has the potential to supply much-needed indigenous raw materials for the medicinal, cosmetics, and food industries.
