Study the effect of texture agents on yogurt’s quality

The effect of presence of gelatin, pectin and starch with 0.5% and carrageenan 0.2% in the yogurt had been studied. Many tests techniques as viscosity, penetration for yogurt gel, whey separation and sensory evaluation had been established and compared.

Recycling Building Demolition Waste In Self Compacting Concrete

The main purpose of the research was to partially replace the reused substrates with natural preservatives. Five mixtures were formed with different percentages of the recycled granules (0- 100%) and for constant W/C, and the study of the possibility of disposal of the ruins of the destroyed buildings through their reuse in the work of the concrete and the positive effect on the environment.

Analyzing Study in controlling the quartz transformation to rise the ceramic strength

the scientific researches go towards applying practical and scientific experiments to achieve these goals. From this point, we try in our research to create strength and increase it for ceramic tiles at phases with lower temperature degree than what is used in industry.

The effect of some food additives in the microbial growth of some starter cultures used in the manufacturing of fermented meat

The research aimed to study the contrast between three commercial starter cultures used in the manufacturing of fermented meat and different concentrations of nitrite, salt, lactic acid and black pepper all alone on the impact of inhibition of the microbial growth. The first starter culture contained a mixture of Staphylococcus carnosus and Staphylococcus vitulinus, and the second one contained Lactococcus lactis and Lactobacillus sakei while the third one contained Lactococcus lactis, Lactobacillus sakei, Staphylococcus carnosus and Staphylococcus xylosus. Four concentrations of each additive were individually prepared and the inhibition activity on the microbial growth was estimated by comparing the total microbial counts with and without the addition of the same additive. Analysis of variance and least significant difference (LSD) test at P<0.05 showed that the lactic acid was the most influential on the microbial growth of starter cultures, and significant differences were also detected between the used concentrations of lactic acid, while no significant effect was observed when 100 ppm of nitrite, 1-3% of salt and 0.1-0.4% for black pepper were used. Consequently, the previously mentioned concentrations could be applied in the manufacturing of fermented meats.

Effect of temperature and exposure time on the stability of Plasticizers, which are used in plastic Packing Industry, in food simulants

Additive migration levels in food simulants from polymeric materials that are intended to be into contact with food can be affected by additive stability under the migration test conditions. In this work, the stability of Dibutyl adipate (DBA), Diisobutyl adipate(DIBA), Diisobutyl phthalate (DIBP), Di-noctyl phthalate (DnOP),and Diethylhexyl sebacate (DEHS).,was studied in aqueous food simulants A, B, C and ethanol 95% (as a substitute for olive oilwhich is a fatty food simulant, simulant D), at different temperatures 20, 40 and 70 ºC, during 20 days. Samples were analyzed by high performance liquid chromatography (HPLC) with UV detector at 270 nm. The stability of the studied compounds appeared to be least of all in simulant B, then in simulant A, and finally in simulant C., When temperature and exposure time increase., on the other hand, the increase in temperature and exposure time have greatly less effect on the stability of plasticizers in ethanol %95,as a substitute for olive oil-which is a fatty food simulant.

Effect of temperature and exposure time on the stability of Some antioxidants, which are used in plastic Packing Industry, in food simulants

Additive migration levels in food simulants from polymeric materials that are intended to be into contact with food can be affected by additive stability under the migration test conditions. In this work, the stability of four antioxidants: Butyleted hydroxy toluene (BHT), Bisphenol A (BPA), Pentaerythritol tetrakis (3,5-di-tert-butyl-4-hydroxyhydrocinnamate) (Irganox 1010), and Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate (Irganox 1076), was studied in aqueous food simulants A, B, C and ethanol 95% (as a substitute for olive oil- which is a fatty food simulant- simulant D), at different temperatures 20, 40 and 70 ºC, during 20 days. Samples were analyzed by high performance liquid chromatography (HPLC) with UV detector. In general, the studied compounds appeared to be more stable in both Ethanol (95%) and simulant B than in simulants A and C.

Effect of temperature and exposure time on the stability of plasticizers, which are Used in plastic Packing Industry, in food simulants

Additive migration levels in food simulants from polymeric materials that are intended to be into contact with food can be affected by additive stability under the migration test conditions. In this work, the stability of two plasticizers: Diethylhexyl phthalate (DEHP) and Dibutyl phthalate (DBP) was studies in aqueous food simulants A, B, C and ethanol 95% (as a substitute for olive oil- which is a fatty food simulant- simulant D), at different temperatures 20, 40 and 70 C0, during 20 days. Samples were analyzed by high performance liquid chromatography (HPLC) with UV detector. In general, DEHP and DBP plasticizers appeared to be more stable in both Ethanol (95%) and simulant C than in simulants A and B, while, they are less stable, even at low temperatures, in Simulant B than in simulant A .

Improvement of Soil Physical Properties at B'lay Area in South Syria to Limit Land Degradation

Land degradation deteriorates environmental systems and has direct and negative effects on crops yield, pastures and forests. Land degradation is an old phenomenon but in the last years it accelerated and spread widely to reach some interne areas in Syria like the studied area (Blay) which situated on the road of Damascus-Sowyda. In this paper morphological, physio-chemical, hydraulic and fertility study was done to clarify and define the reasons of this degradation in this specified area. Three land sections were done and morphologically described on site, soil samples were taken for analyses in the laboratory. Results showed that, the degradation may be related to different reasons like high apparent density which indicates the soil compacting, the low cation exchange capacity (CEC) and the low hydraulic conductivity with a low percentage of available water. Results also showed that the adding different percentage of soil conditioners, like hay, compost, polymer and manure ameliorates in different ratios the physical and hydraulic properties of soil.
