This paper, we evaluated some varieties of local cheeses. samples were collected randomly from various production sites in Homs. Chemical and microbiological analyses were applied to determine their suitability to the Syrian standards. This study shows that 54% of Baladi cheese samples, 25% of Akkawi(Cows), 18% of Akkawi(Sheep), 12% of Kashkawan ,2 %of Chelal samples, that 2% of Halloumi cheese samples, and 8% of Msannara cheese samples contained Escherichia coli bacterium. This results also indicate that 15% of Baladi cheese samples, 12% of Akkawi(Cows), 8% of Kashkawan cheese,4 %of Chelal cheese, and 8% of Msannara samples contained Staphylococcus aureus bacteria. As well as the percentage of Baladi cheese samples containing Salmonella bacteria was 8%, and Akkawi(Cows) cheese samples was 4%, and 2% in Msannara cheese samples. This study indicated that local cheeses have no uniform or standardized chemical characteristics. This study shows that 67% of Baladi cheese samples, 33% of Akkawi(Cows), 83 %of Chelal , and 100% of Kashkawan samples were contrary to the Syrian Normal Standard for dry matter. And all samples of cheese identical to the Syrian Normal Standard for sodium chloride 100%.

Research summary
تهدف هذه الدراسة إلى تقييم نوعية بعض أنواع الأجبان المحلية في محافظة حمص ومدى مطابقتها للمواصفة القياسية السورية. تم جمع عينات عشوائية من الأجبان وإجراء تحاليل كيميائية وجرثومية عليها. أظهرت النتائج أن نسبة كبيرة من العينات تحتوي على جراثيم القولونيات، العنقودية الذهبية، والسالمونيلا. كما تبين أن الأجبان المحلية لا تمتلك خصائص كيميائية موحدة، حيث كانت نسبة كبيرة من العينات مخالفة للمواصفة القياسية السورية فيما يخص نسبة المادة الجافة. ومع ذلك، كانت جميع العينات مطابقة للمواصفة القياسية السورية بالنسبة للملوحة. تشير النتائج إلى وجود تفاوت كبير في جودة الأجبان المحلية نتيجة لاستخدام طرائق تقليدية في التصنيع وعدم الالتزام بالشروط الصحية المناسبة.
Critical review
دراسة نقدية: على الرغم من أهمية هذه الدراسة في تسليط الضوء على جودة الأجبان المحلية في محافظة حمص، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الأفضل أن تشمل الدراسة عينات من مناطق أخرى في سوريا للحصول على صورة أشمل عن جودة الأجبان المحلية. ثانياً، لم تتناول الدراسة تأثير العوامل الموسمية على جودة الأجبان، وهو عامل مهم يجب أخذه في الاعتبار. ثالثاً، كان من الممكن أن تكون التوصيات أكثر تفصيلاً وتحديداً لتحسين جودة الأجبان المحلية. وأخيراً، كان من الأفضل أن تشمل الدراسة مقارنة مع الأجبان المستوردة لتقديم رؤية أوسع عن جودة الأجبان في السوق السورية.

The aim of this research is to study chemical and physico-chemical characteristics of Akawi, Medaffarah, Shankalish and Sorkeh cheeses for their identification and comparison with some internationally widespread cheeses. Several chemical analyses were performed on samples collected from different region famous with these products.
In this paper, we evaluated some varieties of local white cheeses (Baladi and Akkawi). 100 samples were collected randomly from various production sites in Syria between 2003 and 2004. Chemical and microbiological analyses were applied to determin e their suitability to the Syrian standards. This study shows that their quality do not fulfill the set minimum Syrian quality standards. The microbiological analyses (Coliform, Escherichia, Staphylococcus aureus, and Salmonella), rate was 75% for Coliform organisms and 66% for Escherichia in Baladi, while it decreased to 43% for Coliform and 25% for Escherichia in Akkawi. As concerns the positive coagulation bacteria (S. aureus), the rate exceeded 15% for both types of cheeses. 18% and 12% of Salmonella were found in Baladi and Akkawi also respectively. Various types of Coliform and Salmonella were identified. This study indicated that local cheeses have no uniform or standardized chemical characteristics. The averages of acidity, moisture content and salt percentage were 0.24%, 60%, and 2.6%, for Baladi and 0.28%, 53.53%, and 9.96% for Akkawi, respectively. The fat content had a wide range for all cheese samples. This study classified these fresh cheeses as raw cheeses that have vast flora and no uniform chemical and quality characteristics. The above findings, lead to different defects and properties which do not fulfill the Syrian quality standards. Thus, the quality of Syrian cheeses varieties is still questionable.
This study aimed to estimate the concentration of conjugated linoleic acid (CLA) in some Syrian cheeses available in local market and the daily consumption of CLA due to its health importance and nutrition properties. Five types of cheeses were us ed namely, white cheese (12.92% fat) produced from cow's milk, white cheese (14.64% fat) produced from ewe's milk، processed cheese (18% fat), mozzarella cheese (29.18 fat) and vita cheese (Bulgarian cheese, 15.5% fat) produced at different manufacturing units.
The research was carried out in the center of the Research and Improvement of Sheep and Camels in salamiah. The study was conducted on 9 female camels, within semi-open barns, semiintensive care system, and the camels were fed on mixtures of barl ey, vetch and some concentrated fodder, Fodder mixtures were determined to suit the nutritional needs of the physiological and age-related condition of the study. The herd was also applied to the preventive vaccination system according to the preventive immunity program.
The objective of this research to study the chemical composition and microbial load for some types of pies by performing various chemical and microbial analysis of samples collected, from different parts of the Syrian coast which are famous for its production. This study showed a large variation in the chemical composition of samples by type of the pastry and place brought from, for example, the proportion of dry matter for peppers and chard pies collected from Banias was, 75.71% and 44.90%, respectively, and the percentage of dry matter was 73.88% and 76.18% and the proportion of protein was, 17.76% and 24 .88% for cheese pies collected from Tartous and Latakia 1, respectively. This study indicated that all the pies contain a high percentage of fat [the lowest in chard pies (17.64%) and the highest in cheese pies (38.12%)]. Furthermore a high percentage of sodium was found (the highest in cheese pies 15.31 mg / 100 g and lowest in pepper pies 7.82 mg / 100 g). The study also showed that these meals meet international standards in terms of content of lead, cadmium, Nevertheless they are poor in fiber content except for chard pies which were the most balanced in terms of components, making it the best type of pies in nutritional aspect. Finally, the results showed that the microbial load was too high, as the total census of bacteria was higher than 105 and the total census of yeasts and fungi was higher than 102. In addition, all pies are not conformed to the Syrian legislation. The study also showed absence of E.coli and St. aureus of all samples.
