Oil is extracted from locally purchased African Star apple using
Sochlet extractor. Knowledge and
information regarding the elemental composition of the fruits are very
essential both to the human nutritionist and the horticulturist since minerals
play vital roles in the life of both the human being and plants.

CONCLUSION AND RECOMMENDATION
The African Star Apple (Chrysophyllum Africanum), locally called
“Udala” by the Ibos and “Agbalumo” by the Yorubas is found mostly in African
Countries. Its distribution extend from
Sierra Leone to the Congo region and Angola, found in rain forest and
transitional formations, often planted for its edible fruits. Its distribution also extends to Sierra Leone
to Spain, Guinea, extending to Sudan, Uganda, Kenya and Nyasaiano. It is also found in countries like Southern
Nigeria, Cameroons, Ghana, Ivory Coast and Sierra Leone. Chrysophyllum Africanum is of the family
“Sapotacea”. Its habitat is usually on
riverside in closed forest, and often planted in villages. Chrysophyllum Africanum has
different species, but Chrysophyllum Africamum and Chrysophyllum Albidum
bear the same common name in Nigeria “UDALA”. (Okafor 1981).
A medium sized, evergreen three usually 70ft to 100ft high; bole
straight, flitted, bark gray and riddget, slash thin, cale brown, darkening to
orange, Heartwood whitish when first felled, turning a pink buff to an olive
yellow and finally a yellowish brown, not demarcated from the sapwood.
Texture fine to medium, grain straight to occasionally interlocked,
luster rather low; wood contains a pale brown gum. Chrysophyllum africanum bears
edible fruits with large berries containing five large flattened seeds. It is greenish in colour when unripe and pale
orange when ripe. It is pointed at both
ends. The fruits are large and more than
4cm wide, shaped like orange or apple, it is often cultivated for its edible
fruits and the pulp having a pleasant acid taste (Nwadinigwe, 1982).
Chrysophyllum africanum (African Star
apple propagation is by seed either by encouraging natural regeneration or
plantation traditionally. The sapwood is
pale yellow and takes a good polish. It
is fine grained, hard and tough polishes well.
It is used in carving and tourney.
The seeds yield edible oil, which is sometimes used in Ashanti for making
soap. The latex is used as birdlime, the
back is also used medically, often sold in the market and the tree is usually
grown for this purpose.
In parts of Anambra and Imo States, this tree (African Star Apple)
forms the focal point or venue for a fertility rite, in which young girls,
childless wives celebrates a festivity – eating, singing and dancing for the
sole purpose of praying to the gods of birth, this is a gesture of charity,
since children are freely entertained without discrimination or distinction. The African Star Apples are valuable sources
of minerals such as protein, fats and oil, carbohydrates etc. (Okigbo, 1989).
1.2 AIM AND
OBJECTIVE OF THE STUDY
The objective and aim of this Project is to extract the oil of African
Star Apply (Chrysophyllum africanum) seed using sochlet
extraction and to evaluate its potential as a raw material in cosmetic and
The demand for vegetable oil both for consumption and industrial
application is vast, and common sources like palm oil and palm kernel oil are
far stretched that the need for alternative sources is invariable. This has prompted us to ascertain the
quantity, quality and the utilizability of the oil of Chrysophyllum africanum
in industrial and domestic processes.
OF THE STUDY
The justification of this research study is to ensure that the oil
extracted from African Star Apple is circulated or sold. It is also carried out on the basic of making
soap, paint, cosmetics, it is also used in curing jaundice to avoid any sort of
suffering from Jaundice.
In a research project like this, it is always difficult to complete the
work without going through a number of challenges, which constitute
impediments. The time to get information
from the library, and time for the purchasing of raw materials, industrial
machines etc. finance is another constraint a lot of money was needed for
transport, typing, browsing and practical work.
