This research investigates the ability of using cheese whey in producing soft drinks supported with natural juices (peach, orange, apple, and pomegranate). Two kinds of whey (sweet and sour) were prepared in the laboratory, and their most important organoleptic and chemical properties were determined. The percentages of total solids and lactose in sweet whey were 6.2 ±0.2% and 4.5 ±0.2% respectively, while for sour whey were 5.4 ±0.2% and 3.8 ±0.2%. Organoleptic evaluation showed that the fresh sweet whey had medium ability for consumption, while sour whey was rejected by the team of tasters with a significance level of 5%. Organoleptic evaluation also showed that the best percentage for the mixture of sweet whey and juice is 50:50 (v/v) with a very good degree of acceptance. Statistical analysis indicated that the produced drink from orange juice was the best drink at 5% significance level. It was followed by the juices of pomegranate, apple and peach respectively. As a result the sweet whey may be used after mixing it with the other studied juices at a percentage exceeding 40%, (best value is 50%) for the production of good soft drink. This produced drink must be consumed within a maximum period of 24 hours because of its low storability due to the absence of preservatives and heat treatment. Improving this storability requires further studies.

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.
A new analytical method has proposed for determination of five synthetic colorants used in the wine industry (i.e., Tartrazine, Brilliant Black, Sunset yellow, Brilliant Blue and Erythrosine) by reversed-phase high-performance liquid chromatograph y equipped with Diode Array detector. Experimental conditions, including spectral properties, limits of detection and recoveries for these synthetic colorants in detail were studied and assigned according to the statistical methods adopted.
Spices are becoming increasingly important world-wide due to their effectiveness as natural antibiotics, the thing that makes the world nowadays tend to use spices instead of chemical drugs. However, this doesn’t mean they are free of some dangerous pathogens such as Klebsiella spp. which can lead to a wide range of illnesses, notably pneumonia, urinary tract infections (UTIs), and bacteremia. Although we don’t know the natural habitat of this bacterium we find that it thrives in herbs and spices, concluding thus that plants may be its natural habitat. The primary isolation of this bacterium was based first on its growth on general media and then isolation on selective media. Colonies of the microorganisms were counted on different media then Klebsiella was isolated from a selective media. The isolated colonies of Klebsiella were circular, dome-shaped, 3-4 mm in diameter, with mucoid sticky edges, and surrounded by capsule. After this we chose the typical colony and identified it using Polymerase chain reaction PCR and biochemical tests. Our results showed that 32% of examined specimen contained Klebsiella spp.
In this research, two types of studies were conducted: the first type is a quantum study of some uranium compounds, and the second type is an experimental study to separate some radioactive isotopes.
Enterobacter sakazakii is considered an opportunistic pathogen that has been associated with severe lethal infections especially in neonates, elderly, and Immunocompromised adults. E. sakazakii is a Gram negative, facultative anaerobes rod-shaped bacterium. It belongs to the family Enterobacteriaceae and genus Enterobacter. Although we don’t know the natural habitat of this bacteria we find that it exists in high rate in herbs and spices which indicates that plant may be this natural habitat.
