oil" is a comprehensive study carried out with an objective to
assess the qualitative changes of red palm oil during storage.
Red palm oil is extracted from the mesocarp of
oilpalm fruit which is deep red in colour due to its high
carotene content.
The storage study was planned for six
months.
The oil was stored in tins, polythene pouches,
polyteraphthalate bottles, plain glass bottles and coloured
glass bottles.
The analysis carried out to ascertain the
physico-chemical changes in the oil were specific gravity,
smoke point, moisture, acid value, fatty acid composition.
