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% respectively.
Then the dried sample was pulverized by using hammer mill and the oil
was extracted by solvent extraction using n-hexane. The oil extracted
were analyzed for the chemical properties i.e. (Acid value,
saponification value, peroxide value, iodine value) etc. the values
obtained are respectively 8.41gm/KOH/gm, 185.1gm/KOH/gm, 2.8gm/KOH/gm
3.96gm/iodine/gm and Physical properties i.e. (Refractive index, Ph
value, specific gravity) which the values obtained are 1.469brix, 5.7
and 0.92. and the The percentage oil yield content is 51.57%. This
physio-chemical characteristic and fatty acid composition of this oil
show that they have industrial potentials.

CHAPTER ONE - [ Total Page(s): 3 ]CHAPTER ONE1.0 INTRODUCTIONIn the major world, one major source of protein and vegetable oil is from oil seeds /fruits (Williams M. A. 1996). Oil constitutes a well defined class of naturally occurring substance. It is greasy, being soluble in organic solvents but insoluble in polar solvents such as water. Oil is a liquid at room temperature. Commercially, oil as well as fats is sourced from certain plant groups mostly seeds and nuts and some parts of animal within which they occur in relatively ...
