Wild Syringa (Burkea africana) edible tree resin
Many African trees extrude edible gums and resin. Notable Vachellia ssp. and Senegalia ssp. (old name: Acacias) are known for their edible gums. Ju/’hoansi people are collecting and eating whatever edible gums and resins they find on the go. In our case it was resin of Wild Syringas (Burkea africana).
Distribution of Wild Syringa is widespread in tropical- and subtropical Africa and mainly occurs between the Tropics of Cancer and Capricorn.
The outer bark contained on two spots the amount of resin that can be seen at attached photos. The two old women were chewing it without offering something to the men. Obviously, resin is a food of the Ju/’hoansi just for the collectors, although all other roots, fruits and nuts we found were shared amongst all of us on the spot.
Taste of Burkea africana resin is pleasantly mild and resembles the taste of roasted sweet chestnuts. It is neither sticky (like pine resin), nor too brittle – but just the right taste and texture for enjoyment. Calorific value of Burkea africana resin is not known yet, but pine resins for example got a CV of over 38 MJ/kg, which is a medium high value. Wild Syringa resin will have a higher CV due to sugars contained in it. Fungi for comparison got around 17 MJ/kg.
Lessons learned about Wild Syringa edible tree resin:
- Tree resin is used as a kind of snack food for wild food collectors
- Burkea africana resin tastes pleasantly like sweet chestnut
- Calorific value of tree resins is high enough to pay off for the extra energy spent looking for it
