The application of this research was implemented at the laboratories of
Food Science Department, Agriculture College, Damascus University in order
to investigate the effect of different ratios of added oil upon the rheological,
chemical and microb
ial characteristics of mayonnaise. The traditional
mayonnaise was made from fresh egg, vinegar, salt, mustard, citric acid and
corn oil at 70% ratio, to be used as a standard. Two changes in the oil ratio:
40% and 50% were applied for obtaining lower oil mayonnaise, with fewer
calories (Diet). The influence of adding Xantan gum as a substitute to oil
reduction, on the properties of final product was also investigated. Results
showed that the addition of Xantan gum at 1.5% was necessary to complement
the reduction in the added oil. The results also confirmed that reduction in the
added oil of the diet mayonnaise led to reduction in viscosity and firmness when
compared with the standard mayonnaise.
Terebinth trees have been occupying a good part of the mount of Syrian
(abed elaziz, pelass). The Pistacia atlantica fruit, rich in oil, is used by local
inhabitants in many ways, few studies investigation of the P. atlantica fruit oil
of Syria ha
s been carried out,This study investigates the protein, ash, crude oil
and oil composition of P. atlantica with respect to total phenol, iodine value and
saponification value, in order to classify it among the other known edible oils
thenafter compare the oil composition with the oils of other Pistacia species.
The fruit of P.atlantica appears to be rich in oil. The major fatty acid in the
sample studied are oleic, linoleic, our results show that. The oil has a higher
content of unsaturated FA (oleic + linoleic = 72%). The oil can be classified as
an oleo-linoleic vegetable oil. The biochemical data showed an elevated MUFA
content (50-48%) which may constitute an important property against certain
pathologies for its nutritional and preventive virtues.
During the season of 2002, samples of olive fruit were taken (Ashrasi type)
from Ninavah horticulture’s station that belongs to the ministry of agriculture
in Iraq. The purpose of this research is to study some physical and chemical
characteristic
s during the growing period, from July until October. Those
characteristics include moisture, ash, oil content, chlorophyll A & B, protein,
pH and carbohydrate, In addition to fruit length, size, weight, radius, and
rigidity. The results showed significant increase in moisture, oil, weight, size
and length of the fruit were studied. Significant reduction was noticed in the
percentages of the protein, carbohydrate, ash and the fruit rigidity. The highest
values of chlorophyll were observed during The month of September. October
considered as the best time to harvest olive fruits for pickle purpose.
The bio-effect of anise oil and its fruit extracts(alcoholic and
aqueous extract) to control the cowpea beetle, Callosobruchus
maculatus that infest stored leguminous crops was investigated. The
study was conducted according to three treatments: e
vaporation,
direct spray of insects and food spray. The anise oil was used at
different concentrations from 0.05 to 5%. Whereas, the aqueous and
.alcoholic fruit extracts were used as 30%.
This research confirms the great importance of oil and its impact on international relations
at the political and economic levels, which drives the major countries, especially the
United States of America, to secure the necessary oil supplies perma
nently and in any way
possible. The research aims to introduce the most important pillars of US oil policy and the
importance of protecting the oil security belt In general and the Gulf in particular, and the
development of the means followed by the United States to control and exploit the Gulf oil
as far as possible, both through the signing of the agreements of monopoly and even access
to the policy of waging wars or making crises, as research refers to the political and
economic history of the American exploitation of the Gulf oil despite the prevailing belief
that the United States is a strategic ally of the Gulf states. The research founded many
results and made some recommendations.
