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).
Three hundreds and thirty samples of raw milk and some of the Syrian
dairy products collected during 2002-2003 from different areas of Syria, and
were used to detect the presecne of Listeria in these products.
Results indicated that mainly L. mono
cytogenes and to a lesser degree
L.innocua and L.ivanovii were found in these products. The perecentage of
violating of the Syrian standards was 4 % in raw milk, 0.0% in pasteurized
milk, 2% in white cheese, 0.5% in shinglish and 0.0% in ice cream. And it has
been deterhmined the identity of the isolated bacterial species of Listeria from
the above-mentioned products, where L. monocytogenes was dominant, and to a
lesser estent were L. innocua and L. ivanovii.
أجري هذا البحث في مخابر كلية الزراعة بجامعة الفرات قسم علوم الأغذية وفي مخابر هيئة الطاقة الذرية بدمشق وقد هدف إلى عزل وتعريف بعض سلالات بكتريا حمض اللبن من الحليب الخام للنوق والماعز الشامي بالإضافة إلى دراسة بعض الخصائص الكيميائية والتصنيعية للسلالات المعزولة وذلك في عامي ( 2010و 2011)
