A study of chemical composition of woman's milk has been
made and compared with cow's milk in the province of Homs.
The findings of this study show that The total value of the solid
material in cow's milk is (12.26 ± 1.2%). It is approximately
eq
ual to woman 's milk content of the total solid material which
is (12.11 ± 0.09%).
The woman 's milk content of mineral elements is (02% ±
001%), while the cow's milk content is (0.71 ± 0.14%).
For the value of fatty material in the mother's milk, it is (3.5 ±
0.02%) and this is almost equal to cow's milk content of the
same material which is (3.4 ± 0.05%).
The cow's milk content of protein is equivalent to (2.92 ±
0.019%), whereas cow's milk content is equivalent to ( 1.25 ±
0.009%).
The value of calcium in the mother's milk is (32 ± 4.3 mg), and
this is significantly lower than the value of the calcium in cow's
milk, which is (118 ± 8.2 Mg/ kg).
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.
This study was carried out at the laboratory of Food Science Department,
Faculty of Agriculture, Damascus University in order to evaluate physical,
chemical and microbial properties of Akkawi cheese in Syria. Thirty samples of
Akkawi Cheese collec
ted randomly from different Syrian cities and urban
markets during 2011 were analyzed. Chemical and microbiological analyses
were applied to determine their suitability to the Syrian standards. Results
showed that the quality of cheese samples did not fulfill the set minimum
Syrian quality standards and the proportion of the violation of the Syrian
specification for total dry matter in cheese samples studied was nearly 10%,
and 100% for sodium chloride. The study also demonstrated differences in
chemical properties, with an average of acidity, moisture content 0.34 %, 53.9
% respectively. The fat content had a wide range for all cheese samples. On the
other hand, the proportion of health violation for this type of cheese from the
Syrian standard was 73.3 % for Coliform bacteria and 56.6 % for the E. coli.
but they were acceptable for the existence and account of Staphylococcus
aureus , Salmonella and Listeria.
Yarmouk basin is considered one of the important basin in Syria due to its
economical contribution in the total national production of the country.
Also water plays a vital role in this effective activity of the economical
development, the purpose
of this research is to study the pollution in the southwest
area inYarmouk basin on three levels: chemical, chemi-toxical and the
Bacteriological.
The study was done on three different sites which are: the outlet of Almzereeb
lake, Zeizoun spring, Daael Al-kadeem well. The results were as
follows:
The rates of the concentration of both the ammonium and BOD in Zeizoun
spring and Al-mzereeb lake high, where they exceeded the allowed limits in the
drinking water of Zeizoun spring. But they remained within the allowed rates
in the irrigation stander of Al-mzereeb lake, while there wasn’t any remarkable
rising for such ions in the well of Daael Al-kadeem.
Fifty clones of local seeded apricot (Klabi). Prunus armeniaca L. were
classified AL-Goutta orchard during ١٩٩٦–٢٠٠٠ . These clones were analyzed
in terms of physical and chemical characteristics with the objective of selecting
individual clones (
For dried apricot sheets) that meet the standard
specifications.
