Comparative Study of Chemical Properties Between Woman's Milk and Cow's Milk

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 equal 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).

Detecting the Listeria in Raw Milk and Some of the Syrian Dairy Products

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. monocytogenes 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.
