Two strains of probiotic bacteria were used in this study for supplying processed spread cheese which are: Lactobacillus acidophilus LA-5, Lactobacillus casei 431 . Their total count after eight weeks of refrigerated storage was 1.4×107 and 2.6×107 cell /g consequently .These numbers are higher than recommended ones to show the positive impact on the consumer's health. The results of sensory evaluation by panelist show no significant differences at 0.05 in sensory characteristics between processed cheese that supported by probiotic bacteria and unsupported processed cheese, Both kinds of processed cheese had got acceptance of consumers & panelist. The results of this study show that the processed spread cheese is a suitable medium to transfer probiotic bacteria to consumers without any changes in sensory characteristics and chemical composition.

Research summary
تتناول هذه الدراسة عملية تصنيع جبن قابل للدهن مدعم ببكتيريا البروبيوتيك، وتحديدًا سلالتين هما Lactobacillus acidophilus LA-5 وLactobacillus casei 431. تم تخزين الجبن المبستر المدعم بالبروبيوتيك في الثلاجة لمدة ثمانية أسابيع، وأظهرت النتائج أن عدد الخلايا الحية من البكتيريا في الجبن بعد هذه الفترة كان 1.4×107 و2.6×107 خلية/جرام على التوالي. هذه الأرقام أعلى من التوصيات الصحية، مما يشير إلى تأثير إيجابي على صحة المستهلك. أظهرت التقييمات الحسية التي أجراها مجموعة من المختبرين عدم وجود فروق معنوية في الخصائص الحسية بين الجبن المدعم بالبروبيوتيك والجبن غير المدعم، مما يعني أن الجبن المدعم بالبروبيوتيك قد حصل على قبول المستهلكين والمختبرين. تشير نتائج الدراسة إلى أن الجبن القابل للدهن هو وسيلة مناسبة لنقل بكتيريا البروبيوتيك إلى المستهلكين دون أي تغييرات في الخصائص الحسية والتركيب الكيميائي للجبن.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة في مجال تعزيز الأطعمة بالبروبيوتيك، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، لم يتم التطرق بشكل كافٍ إلى تأثيرات التخزين الطويل الأمد على فعالية البكتيريا البروبيوتيك. ثانيًا، كان من الممكن توسيع نطاق التقييمات الحسية لتشمل مجموعة أكبر وأكثر تنوعًا من المستهلكين لضمان نتائج أكثر شمولية. أخيرًا، لم يتم مناقشة التكاليف الاقتصادية لإنتاج هذا النوع من الجبن مقارنة بالجبن التقليدي، وهو جانب مهم يجب مراعاته عند التفكير في تطبيق هذه التقنية على نطاق واسع.
Questions related to the research

The aim of this study is to use local cheese and additions in producing processed cheese spread with good sensory and chemical characteristics. The results show that the best mixture can be used through experiment and sensory evaluation, where the percentage of total dry material in produced processed cheese is 38.6%, fat percentage is 53% and total count bacteria after manufacturing & after storage for 8 weeks in temperature of 5-7° is 5×101 cell/g. These bacteria are gram positive rod bacteria spores. This means that heat processing was highly efficient in destroying the green bacterial cells, and storage in temperature of 5-7° doesn't allow growth of bacteria spores. While samples which stored in temperature of 20-25° show increasing total count bacteria from 5×101cell/g directly after manufacturing to 12×101 & 20×101 cell/g after 8 weeks of storage without any changes in quality characteristics. We conclude from these results that this product needs refrigerated storage, for conservation product quality if storage more than 8 weeks.
The study investigated the survival ability of probiotic Lactobacillus casei in apple juice to produce functional juice ,as well as, optimizing the growth conditions of L.casei in apple juice including concentration, temperature ,inoculum size usi ng Response Surface Methodology as statistical method.
The Ultrafiltration (UF) technology was conducted on samples of akawe cheese whey to obtain the non-protein and fat whey (permeate) that rich in lactose and was concentrated by evaporation and carefully prepared after fortification by nutrients, (0.2) gr/100ml (NH4)2Hpo4 and (0.2) gr/100ml MgSo4, and (0.3) gr/100ml (NH4)2SO4, and prepared as a fermentation medium for yeasts capable of metabolizing sugar, and after that (15) samples were chosen and chemically analyzed along with the whey. Pure isolated Kluyveromyces lactis (42-K) yeast, recognized by ß- galagtosidase enzyme and its important application in food, medicine and pharmacy, was proliferating on the fermentation medium. The optimal conditions were determined to obtain single cell protein (SCP). The results referred that typical conditions of yeast growth were (6.5)% lactose concentration, pH (5), temperature (30°c), Fermentation time (24) hour, and the optimal speed of incubator shaker (350) rpm and the typical average of aerator (8%). The optimal values were applied in the bio fermentor (electrolab) to obtain biomass which was heated at (75-90 c°) for the extraction of the Single Cell Protein (SCP). The chemical analysis was conducted on (15) samples of single cell protein (SCP), and the results were in accordance with all the Syrian special specification, and (FOA) specification. The microbial estimated results met (FOA) specification, and the product was free from toxicity elements and cancered factors, which proved that the product was with high quality of proteins. The single cell protein (SCP) was added to Labneh, that manufactured by direct method, and to the proceed speared cheese between (1-10%), alternately with dried skimmed milk. The chemical and microbial analysis of Labneh met all the Syrian special specification and international codex. The result of sensory evaluation referred that percentage of single cell protein (SCP) must not exceed (4%) in the Labneh. The chemical and microbial analysis of proceed speared cheese met all the Syrian special specification and international codex. The result of sensory evaluation referred that the percentage of single cell protein (SCP) must not exceed (3%) in the proceed speared cheese. The results of a simplified feasibility study on the Labneh supported by single cell protein (SCP) (4%), and proceed speared cheese supported by single cell protein (SCP) (3%), referred to good gaining both of the products.
