Four strains of lactic acid bacteria (LAB) from different genus، species and
sources were tested for their abilities to bind of AFM1 for 14 hours.
Lactobacillus rhamnosus LC705 showed higher ability to bind AFM1 (88.35%)،
followed by Bifidobacteri
um bifidum BG1 (84.21%), Lactobacillus bulgaricus
R21 by 80.41% and finally Streptococcus thermophilus by 71.52% after 14
hours of incubation.
In this research, we have measured the radioactivity resulting from the Cesium-137 and Potassium-40 isotopes, in milk samples (from different sources) in Lattakia’s regions. It has been found that all samples were not contaminated by Cesium-137, but
it was recorded that all samples containing radioactivity resulting from the Potasium-40 isotope with a magnitude range between , and average value . As compared with other world results, there was a good agreement between them, taking into account the errors in measurements.
This study was carried out in Lattakia province/ Syria during the 2012 season, in
order to recognize the current situation of milk marketing and detect the problems and the
obstacles that facing it in Lattakia.
The area of study included four regi
ons (latakia-Alhaffa- ALqurdaha and
Jableh)where couple of villages in each region was studied, and the raiser were divided
into categories regarding to the number of their cows. A specific questionnaires were
distributed on the keepers included the following questions: farm location, holding size, the
quantity of production, production costs, manufacturing costs (if present), packaging and
transport costs, the marketing chain for milk, the marketing costs, the marketing margin
and problems faced by the raiser.
Ninety-nine randomized samples of milk and white cheeses were collected
from five districts in Damascus city during 2012-2013 to determinef Aflatoxin
M1 using High Performance Liquid Chromatography (HPLC). The procedure
for determination of Aflato
xin M1 was changed according to local
circumnutates which gave sensitive and accurate results during 5.9 minute with
r= 0.99. The average recovery was 83.88% for milk and 102.15% for cheeses
samples, respectively.
The objective of this investigation was to determine the effective of
microwave radiation on Escherichia coli contaminating milk and in white cheese manufactured of milk by traditional method.
This investigation was conducted at the laboratory of Food Science
Department, Faculty of Agriculture, University of Damascus to determine the
effectiveness and the impact of using microwave radiations to reduce or
eliminate Salmonella typhi in co
ntaminated milk and in white cheese
manufactured by traditional method made of contaminated milk.
Results showed that the duration of 60 sec. was enough to eliminate the
S.typhi from milk heated up to 90₀ C and the best treatment was when exposing
cutting cheese for a period of 240 sec, and the temperature reached 85 ?C and
for a period of 300 sec with a temperature reached 100₀C. Presence of water
helped raising the temperature of the cuttings to be equivalent to the hot water
temperature, (100₀C) and to eliminate greatly bacteria S.typhi in cutting cheese.
It was concluded that the use of microwave radiation was safety to destroy
S.typhi in milk and white cheese.
A total of 294 samples of raw-unpasteurized bovine milk and variety of
dairy products (hard cheese, sweet cheese, cream cheese and cream), were
collected from local markets in Lattakia city as well as 44 samples of used water
(clear potable water
collected before used in cheese preparing processes) and
preserving water (turbid water collected from hard cheese preserving tanks).
All samples were analyzed for E.coli O157: H7 detection.
The evolution of milk production was studied in the country for the period
1994-2008 by measuring the role of horizontal and vertical expansion factors.
Results showed that:- Horizontal expansion factors played the main role in
determining the dev
elopment trends of milk production in the country during
the studied period, and that not in accordance with global trends in this area, so
that 98% of the changes in production were interpreted by the changes in the
numbers of cattle and 87% of the increase in production achieved Due to a rise
in the numbers of cattle, which increased by 4.5% annually, while the
intensification of production factors contribute only about 13% of the increase
in production. - The policy for changing the structural composition of the herd
of cattle by type and which was based on the reduction of the proportion of
cows low-productivity local cattle and focus on raising the proportion of cows
improved in the herd had positive results, however, that these results came very
modest, and did not lead to a substantial increase in annual production for
cows during the period studied only by 0.7% only.
the residual lead effect in cows milk was
studied in the Governant of Tartous. For this end,135 dairy cows in
different milking seasons and from three different farm stationes
(Zahed cow station,Cement factory farm station and Banias refinery
cow
station) were used.
The objective of the study was to accurately determine lead
concectrations in cows milk in the three different farms. Samples of
milk,soil,water and feedstuff were collected and lead concentration
was determined then statistically analyzed.
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.
