Abstract:
In
this study, olive oil samples of different irrigation system in
Palestine were studied. The density, refractive index, acidity and
viscosity of the samples were measured. The results indicate that
acidity increase for samples with trees irrigated by waste water which
can be classified as Lampante oil. The experimental results of viscosity
showed that the viscosity increased for all samples were irrigated by
waste water.
The concentration of some metals in olive oil samples irrigated by waste water have high concentration compared with literature. These metals are: calcium, sodium, potassium, magnesium and zinc. The concentrations of iron, copper and lead for irrigated samples by waste water are greater than concentrations of established by standards of IOOC. The presence of these metals in olive oil may be due to the abundance of them in waste water. The concentration of cadmium and manganese found at high concentration for Hawara samples because it is industrial area.
