1.3 STATEMENT OF THE PROBLEM
This
research work involves the analysis of African pear and its oil though
the food crop African pear potential is rated one of the highest oil
producing fruit crop yet it begs the question of its potential.
Furthermore, this project will answer the following questions;
i) Solvent extraction by solvent method
ii) What is the optimum yield of the particle size using n- hexane?
iii) Is there significant difference in the characterization of the extracted oil as compared to theoretical value in terms of;
1) Chemical properties (Acid value, iodine value, saponification value and peroxide value).
2) Physical properties (specific gravity, density, viscosity, refractive index).
3) Chemical composition (protein crude, fibre, carbohydrate and moisture.
1.4 SIGNIFICANCE/ECONOMIC IMPORTANCE OF THE STUDY
Characterizing
the potentials of African pear/African pear oil for many purposes has
several implications. Communities in the West African countries are
significantly dependent on financial gain from agrarian enterprise.
It
is hope that from the project, optimum extraction parameters which are
quality of the oil would be established, the result would add to the
data bank that could help potential industrialist who intends to go into
vegetable table oil production from African pear. A crop that
experiences a post harvest loss in excess of 40% in areas where
malnutrition is prevalent is a problem for potentials to reclaim the
lost percentage of either food or other purposes is advantageous for
producers and consumers alike.
Furthermore, the development of crops
with indigenous appeal can strengthen the agricultural and energy
sectors of struggling economics, identifying the oils fuels quantities,
whether favorable or not, will help to inform future crop and industry
development.
1.5 SCOPE AND LIMITATION OF THE STUDY
In this project
work, we intend to analyze and extract completely African pear and its
oil. Many research work has been done in giving a detailed composition
found in African pear. But this research account on the optimum route
to:
i) Extraction of vegetable oil from bush pear.
ii) Separation of pure oil from the solvent.
iii) Characterization of the African pear.
iv) Characterization of the oil extracted.
Due
to the low yield of the above method (mechanical method) of extraction,
soxhlet and cold method of extraction are used i.e. solvent extraction.

ABSRACT - [ Total Page(s): 1 ]The research project studies the analysis of pear and its oil. The
mesocarp from edible African pear “DacryodesEdulis†were evaluated for
their oil yield. The pulp from this pear were oven dried at 100oC-105oC
to a moisture content level of 29%.The mesocarp was subjected to
proximate analysis to determine the percentage of the moisture, ash,
fat, crude fibre, crude protein and carbohydrate content which resulted
to the values of 29%, 2%, 19.6%, 25.5%, 11.9%, and 12% respe ... Continue reading---
