CHAPTER ONE
1.0INTRODUCTION
Orange is from the citrus family, the
fruit’s size varies with cultivars and crop load, but most often measure
between 2.5-4 includes in diameter. The shape of the fruit is spherical
to oblong, with a peel thickness between that of grape fruit and
tangerine and it is either smooth or rightly pebbly. The presence and
amount of seed, depends on the cultivar (Nwobi et al, 2006).
Papaya
(carica papaya) is a plant that grows wild in many part of the tropics.
papaya is important for its fruit and it is cultivated mainly for this
purpose (Puangsri et al, 2005). It varies in size, most are oblong,
globular or round, often five angled and narrowed at the tip. Inside
hollow of the fruit is lined with numerous dark grey seeds. The seed of
papaya and orange fruits are generally discarded.
However in other to
make a more efficient use of papaya and orange, it is worth
investigating the use of the seeds as a source of oil. The extraction
and use of vegetable oil has for centuries played an important role in
the manufacture of large number of industrial product and food items
(puangir et al, 2005)
Kar and Mital (1999) reported that shear butter
is a natural fat obtained from the seeds of the shea tree Butyrespermum
park: the shea butter fat was extracted from the seeds with various
organic solvents such as petroleum ether, n- hexane, chloroform and
benzene. It is concluded that these solvents, particularly petroleum
ether and n-hexane, could be used for the extraction of shear butter
that is free from any oxidized fat and coloring impurities. Akpan et al
(1999) carried out extraction and characterization of castor seed oil
and reported that tested parameters which include specific gravity,
refractive index, acid value, saponification value, and iodine value for
both crude and refined castor oil product were of good quality.

ABSRACT - [ Total Page(s): 1 ]The seeds of pawpaw and orange are generally discarded. However, in order to make a more efficient use of pawpaw and orange, it is worth investigating the use of the seeds as a source of oil. In this work oil was extracted from the seeds of both pawpaw and orange. The specific gravity, iodine value, acid value, peroxide value, saponification value and moisture content of pawpaw seed oil were determined and the result are 0.85, 30.20, 47.12, 48.60, 79.38, and 0.18 respectively. Similarly, the fol ... Continue reading---
