Palm kernel oil is not usually extracted on the plantations, though occasionally mills contain press designed for this purpose.
The
conditions for the release of palm kernel oil, which is liquid at
tropical day temperatures, are different from those of palm oil, but
similar to those of copra and hand oil bearing seeds.
Very small
quantities are extracted in producing countries by primitive means but
the greater bulk of the palm kernel produced are subjected to industrial
process.
Although the extraction of palm kernel oil from palm kernel
is not a new project, this project is capitalized on using different
types of refining processes to determine the one that will yield a
higher output.
Further cultural and agricultural practices differ for
its fruit species depending on the type of soil, different samples from
different localities were collected in consideration to its essential
commercial plantings on which each sample produces high quality
fruit/seed and profitable yield. Thus this research study is being
conducted.
1.3 STATEMENT OF PROBLEM
Palm kernel oils consist
mainly of glycerides, and like other oils in their crude form, may
consist of small and variable portions of non-glyceride components as
well. In order to render the oils to an edible form, some of these non
glycerides need to be either removed or reduced to an acceptable level
so as to meet the request of the buyers.
Therefore, this project aims
at reducing the non-glycerides present in oil in their crude form using
the chemical (alkali) method of refining.
1.4 AIMS/OBJECTIVE OF THE STUDY
1. Reduction of the free fatty acids from 5.0 to 0.03 percent or less.
2. Production of a fully deodourized product.
3. Operation without substantially greater utilities consumption than a standard deodourizer.
4. Recovery of the fatty acids from the sparge stream.
5. Obtaining a mixture of traicylglycerols with the desired solid content profiles over the range of product used;
6. Preparation and storage of semi-solid products with desire textures.
1.5 SCOPE OF THE STUDY
The
refining of crude palm kernel oil is converting it to quality edible
oil renewing objectionable impurities to the desired levels in the most
efficient manner where possible, losses in the desirable components are
kept minimal.
After refining of crude palm kernel oil, a good quality
has low free fatty acid (FFA) content, does not contaminate with water
or other impurities and has a good bleacheability.

ABSRACT - [ Total Page(s): 1 ]This work studied the refining of crude palm kernel oil derived from the kernels within the nut of a palm fruit.This research project was aimed at reducing the non-glycerides present in oil in their crude form using an alkali method of refining.The crude palm kernel oil was first washed with distilled water by heating the mixture in an electric heater for about 2 hours to reduce the impurities present in the oil in their crude form, degummed with phosphoric acid and neutralized with NaOH (causti ...
