This paper describes a study of the influence of extraction system
(centrifugation and pressure system) on the chemical composition and sensory
quality of Dan virgin olive oils produced in Syria. Analysis of the effect of the
extraction system on
the values of analytical determination revealed
statistically significant differences (P≤0.05) in a few parameters only, mainly in
antioxidant content and oxidative stability. The results appear to confirm the
influence of the extraction system on the quality of Dan virgin olive oils.
This investigation was carried out on fifteen years old Sorani and Kaissy
olive cultivars (Oleaeuropaea L.) trees grown in Basaltic soil that
was poor in organic matter and potassium.
The aim of the present investigation is to study the effect of
different
amount of organic and potassium fertilization on yield, fruit weight,
oil percentage, and oil acidity.
Results obtained showed that the highest value of fruit weight, yield, and
oil precentage exhibited statistically the highest values by trees
fertilized with the treatments (Organic + Potassium).
Acidity increased in (Organic + Potassium) treatments but it was less than
2% oleic acid , while it was less than 1% oleic acid in Potassium
treatments and in Organic treatments (Extra vergin oil).
This research aims to study the sterols which is considered, one of the most
important minor compounds, and characterizes vegetable oils.Ten items were
selected from the planted seeds of safflower in Syria in the spring of 2010.
Oil was separated
from seed oil extraction with petroleum ether, then the
content and content of the sterols were specified by using gas chromatography
according to the standard method in the appointment of sterols in olive oil. The
study concluded characterize safflower seed oil sterols from their content,

The research was aimed to study the effect of olive press methods on the oil quantity and quality. The results showed the following:
The method of press Olive effect to the quantity of Olive oil so the results of oil quantity from olive fruite p
ress in mechanical olive press method more above from half mechanical method and from traditional method ( the witness). The increase of quantity between mechanical and traditional method was 60% and between mechanical half mechanical method was 27% and bween half mechanical and traditional method was 28%.
The method of press Olive effect to the of Olive oil quantitatively the results of oil quantitatively from olive fruit press in mechanical olive press machines to surpass half mechanical olive press that is the flavor and color best and Acidity presumption and peroccid number is less .
