ABSTRACT
This project was done to extract and characterize bean oil according to their particle sizes. The experiment was carried out using scent bean (i.e. ‘Ozaki’, ‘Ijilizi’or ‘Azamu’) as sample. The oils were extracted by solvent extraction /leaching extraction using n-hexane. Proximate analysis was carried out to obtain percentage moisture content, ash content, total oil content, protein content and carbohydrate content of the extracted oils. From observation, it was noticed that as the diameter of the sieve decreased, the quantity of oil obtained increased.
CHAPTER ONE
1.0. INTRODUCTION
1.1. BACKGROUND OF THE STUDY
There has been an increase in the world production of oilseeds over the last thirty years (Murphy, 1994); this would appear to be related to the increasing demand for oilseed products and by-products as oilseeds are primarily grown for their oil and meal.
Oils from most edible oilseeds are used in the food industry, though there is growing emphasis on industrial utilization as feedstock for several industries with about 80% of the world production of vegetable oils for human consumption. The remaining 20% utilization is between animal and chemical industries (Murphy, 1994).
According to Rajagopal et al. (2005), bio-oils from oilseeds are used as Straight Vegetable Oil (SVO) or as biodiesel (trans esterified oil) depending on type of engine and level of blend of the oil; scent bean oil i.e. Ozaki, Ijiliji, or Azamu is found mainly in the South-East of Nigeria and is not an exception. This phenomenon has created a school of thought that it is better to use oilseeds as bio-fuel, which will lessen the competition for fossil fuels, which are not renewable. Fossil fuels are not only costly in terms of price but are also costly to the...
