Kpangnan - African Butter Tree (Pentadesma butyracea)
Kpangnan, pronounced "pie-nya," has been
sold in the USA as "golden shea butter" or "yellow
shea butter," in fact it is from a completely separate species
of tree. Read more below and click on each picture for a larger

Kpangnan is the butter from the Butter Tree (Pentadesma
butyracea), a tree which grows in the gallery rainforests and
riverbank forests along the west coast of Africa from Sierra Leone
to Cameroon. Local names for this butter include Kpangnan (or painya)
as well as kanya (Benin), kanga or lamy butter (Sierra Leone), Akpoto
(Togo) among others. Kpangnan is traded locally across West Africa,
and especially in central Togo and Benin. It has also been traded
internationally, but under a false name. P. butyracea butter
has and is being sold in the United States as "yellow shea butter"
or "golden shea butter." In actuality, shea butter and P. butyracea
butter are from two distinct species of trees (Figure 1).

tree (L) and African butter tree (R) habitats. |
These trees are not even in the same genus and grow
in entirely different habitats. As a result, their ecologies are
quite different. The African tallow tree grows in the dense, wet
forests along river banks and low areas (called gallery forests),
while shea trees grow in the open savanna (Figure 2). The African
tallow tree prefers the shaded, wet conditions. Shea trees on the
other hand thrive in the full sunlight and are drought tolerant.

kernels. |
An interesting aspect of the African tallow tree
is that is it pollinated by bats, specifically the African long-tongued
fruit bat (Megaloglossus woermanni). The shea flowers are
not as large as those of the African tallow tree and are insect
pollinated. While the kernels of the two species are somewhat similar
in appearance (Figure 3), the fruits are quite distinct from each
other (Figure 4).

The butters of the African butter tree and the shea
tree are also quite different. Although their fatty acid profiles
are quite similar (Figure 5), their non-fatty constituents differ.
For instance, while unrefined shea butter has an unsaponifiable
content of 5% or more, Kpangnan has only 0.8% unsaponifiable matter.
The saponification (SAP) values of shea butter and Kpangnan are
also quite different. The SAP of unrefined shea butter is between
128 and 134, while that of Kpangnan is 191. A unique characteristic
of Kpangnan is the unexpected high fraction of stigmasterol (about
45% of the sterol fraction). Stigmasterol is an unsaturated plant
sterol usually found in occurring in plant fats like calabar bean,
soybean oil, rape seed and cocoa butter.

Stigmasterol is used as a starting material in the
manufacture of synthetic progesterone, but has other interesting
properties as well. Some research shows stigmasterol can lower the
risk of certain cancers, including ovarian cancer. Certain extracts
of stigmasterol have also been found to be affective topical anti-inflammatory
agents. Other differences between shea butter and Kpangnan are color,
texture, and odor. High quality, unrefined shea butter is a beige
color with light green or yellow tint. Kpangnan is a bright, clear
yellow (Figure 6). Shea butter is creamier than Kpangnan, although
both butters have a smooth feel.

Like shea butter, Kpangnan has been used in central
Togo for generations. Kpangnan is used for skin moisturizing and
treatments, a food oil, and for traditional soaps. Kpangnan is of
particular interest for sustainable development programs because
the tree grows in potentially endangered habitat. Adding value to
this indigenous resource will encourage conservation of the gallery
forest habitat and protect it from deforestation. Agbanga Karite
is working with local gatherers in central Togo to protect both
shea trees and the African butter tree. We feel it is a great honor
to be able to bring you another wonderful indigenous product from
our communities.
