  Background and Objective: Producing healthy and functional dairy products are still having great demand. The aim of present study was to prepare a new or imitated processed cheese spreads convenient to consumers who suffer from high blood pressure and also to prepare sweet processed cheese suitable for children. Materials and Methods: Pumpkin processed cheese spreads (PPCSs) were manufactured by using 3 ratios of pumpkin paste (5, 10 and 15% w/w) to serve 3 treatments (T1, T2 and T3, respectively) and compared with control. Chemical parameters like total solids, ash, protein, fat and fiber were achieved. Potassium and sodium contents were also displayed besides texture profile and antioxidant activity of PPCSs. Sensory evaluation was also carried out of all final samples. Statistical analysis was performed by using the User's Guide of SAS. Obtained data indicated that there were no significant differences in total solids and ash contents between treatments with different ratios of pumpkin paste and control samples. Results: For fiber content, it was increased by increasing the ratio of pumpkin paste comparing to control one. On the other side, the more concentration of pumpkin paste in cheese spread samples, the more content of potassium and the less content of sodium. Thus, increment the rate of pumpkin in processed cheese caused contract the ratio of sodium/potassium in the final product. Scavenging of free radicals of pumpkin-processed cheese samples were in rise by increasing the ratio of pumpkin percent. The highest percent of pumpkin paste (15%) had significantly (p<0.05) gained the highest content of phenolic compounds (205 mg/100 g gallic acid). Texture profile data revealed that addition of pumpkin paste in the blends decreased the firmness of processed cheese compared to control. Decreasing in firmness was inversely proportional with increasing pumpkin paste ratios in the blends. It was 7.289, 6.801, 5.952 and 4.961 N for control, T1, T2 and T3, respectively. Conclusion: It was concluded that preparing a sweet processed cheese spread analogue using 10% pumpkin paste gained the preferable acceptability and success to prepare new sweet product suitable for children and patients who suffer from hypertension. Treated samples had low sodium and more potassium contents.

  Background and Objective: In Egypt, small and medium projects (SMP) are pivotal in meeting the requirements of the local market of dairy products such as soft, hard cheeses and fermented milks. The aim of this research was the study of technological and production determinants mainly production and marketing technology, in small and medium production projects. Methodology: The research method deal with 40 enterprises in Greater Cairo area. Quantitative analysis, multiple regression, one-way ANOVA, morality test (T), (F) and less significant difference (LSD) were applied by SPSS. Results: Obtained data indicated that there were significant differences at (p<0.01) when measuring the effect of the technological determinants of the quantities used in production and marketing. The increase in the number of technological processes produced by one process of production conditions lead to increase the quantity of used milk by 0.39 t and about 35.2 kg of marketed quantities. While, increasing in technological marketing process lead to increase the amount of milk used in production by 0.31 t and about 33.6 kg of marketed quantities as a result of improved production and marketing level. However, increasing the diversity of products to the production unit with a new product was lead to increase the quantities of milk by 0.48 t and about 46.1 kg for marketed quantities. On another hand, the results showed that there were significant differences (p<0.01) between the production and marketing problems as obstacles, facing the workers, in dairy production and marketing units. Conclusion: Present study recommends that encouraging unregistered productive enterprises to enter the formal economy of the country, facilitate loans, registration procedures and exemption from taxes for a specified period in exchange for their entry into the formal economy of the country. In addition, supporting the producers, technically, through the competent institutions. As well as, supporting funding programs for these projects, providing technological means for production and marketing and finally, tighter control to reduce the use of preservatives and unhealthy materials.

  Background and Objective: The dairy industry consumes great amounts of water and generates large quantities of wastewater. The study problem is the lack of available water resources which reflected in decreased average per capita water. The main objective of this study was to study the efficiency of water use in the production units, estimate the cash yield of the water unit and finally study the factors that affect them. Materials and Methods: Data were analyzed using Statistical Package for Social Sciences (SPSS) version 16. Quantitative data were presented as Means±SD. The independent sample- ANOVA was used with two-way analysis of variance, with Post-hoc (LSD) test was used to analyze mean difference. Probability values (P) of less than 0.05 were regarded as statistically significant. Results: The most important results of the study suggested to the low average per capita average annual attrition rate of about 1.29% and rising share of water resources industry with a growth rate of approximately 15.1% during the study period have been measuring the significance differences between the sample in the water-use efficiency, proven statistical model significant at level p<0.05. Also, suggest the disparity in the percentage of the cost of employing and run water to an average of about 5% of total operating costs, as well as indicate low efficiency rate. Conclusion: The study concluded that a clear plan Inspection Department on how to deal with these facilities over the long term and anaerobic biological treatment in processing the high organic content industrial pollutants.
