Croissant is a light, sponge texture, flaky, crescent shaped breakfast roll made from white yeast-raised dough interleaved with butter in the same way as puff pastry. Factors studied included a combination of different levels of weak acid salts preservatives (potassium sorbate, calcium propionate, and sodium benzoate; 0–0.3%). Samples storage for 4 months, pH, water content, water activity, texture and fungi account were measured in different times.

Research summary
تتناول هذه الدراسة تأثير إضافة المواد الحافظة على مدة حفظ الكروسان. الكروسان هو معجنات خفيفة ذات لبابة إسفنجية ورقاقية، تُستخدم في وجبة الإفطار. تم دراسة تأثير تراكيز مختلفة من أملاح الحموض العضوية الضعيفة مثل سوريات البوتاسيوم، بربيونات الكالسيوم، وبنزوات الصوديوم على مدة حفظ الكروسان. تم تخزين العينات لمدة أربعة أشهر وقياس عدة مؤشرات مثل قيمة pH، الرطوبة، الفعالية المائية، القوام، وتعداد الفطور بأزمنة مختلفة. أظهرت النتائج أن استخدام مزيج من سوريات البوتاسيوم بتركيز 0.2% وبربيونات الكالسيوم بتركيز 0.2% معاً كان فعالاً في حفظ الكروسان لمدة أربعة أشهر من الفساد الميكروبيولوجي. كما تم إجراء اختبارات متعددة على العينات لتحديد التراكيز المثلى من المواد الحافظة. توصلت الدراسة إلى أن التراكيز المثلى هي 0.2% من سوربات البوتاسيوم، 2.0% من بريونات الكالسيوم، و0.016% من بنزوات الصوديوم. وأوصت الدراسة باستخدام مواد محسنة للقوام وتغليف غير نفوذ للرطوبة والأوكسجين لزيادة مدة الحفظ.
Critical review
دراسة نقدية: على الرغم من أن الدراسة قدمت نتائج مفيدة حول تأثير المواد الحافظة على مدة حفظ الكروسان، إلا أنها لم تتناول بشكل كافٍ تأثير هذه المواد على الطعم والنكهة، وهو جانب مهم يجب مراعاته لضمان قبول المستهلك. كما أن الدراسة اعتمدت على تخزين العينات في ظروف محددة، ولم تأخذ في الاعتبار تأثير درجات الحرارة والرطوبة المختلفة التي قد تواجهها المنتجات في الأسواق. بالإضافة إلى ذلك، كان من الممكن أن تكون الدراسة أكثر شمولاً إذا تم اختبار تأثير المواد الحافظة على أنواع أخرى من المعجنات.

This study was conducted in order to prolong the period of validity of yoghurt by adding probiotics consisted of Lactobacillus acidophilus LA-5 and Bifidobacterium animalis subsp lactis (Bb12) to milk allocated to yoghurt industry and studied the microbial, chemical and sensory characteristics of yoghurt during storage periods for 0, 7،,14, 21, 28, 35 and 42 days at 4 ± 1 °C and 10 ± 1 °C. The results of microbial characteristics showed that the vital force of the first starter lasted for 7 days in the control samples while lasted for 35 days for the sample containing Lactobacillus acidophilus LA-5 or Bifidobacterium animalis subsp lactis (Bb12) when stored at 4 ± 1°C. Adding probiotics did not affect the taste, smell and pH of the yoghurt without change in the property values during storage periods. It was also found that the shelf – life of control samples can be prolonged and consumed safely up to 7 days of storage while it was prolonged for 35 days in yoghurt samples containing probiotics.
This study was conducted in order to prolong the period of validity of yoghurt by adding 5, 10 and 15 g/1 of carrot juice liter during the storage period of 35 days at 4±°C and 10±1 °C and determine some of the microbial، chemical and sensory char acteristics of yoghurt after 1, 7, 14, 21, 28 and 35 days of storage. The results indicated that the vital force had lasted for 7 days in control samples and 28 days and 35 for samples containing 5, 10 g or 15 g carrot juice, respectively when stored at 4±1 °C. No significant differences were observed when samples stored at 10±1 °C. The results also indicated that the sensory properties of yoghurt containing 5g of the carrot juice were more favorably than those containing higher proportions due to the absence of taste and color of carrot juice in the samples. it was also shown the addition of carrot juice did not affect the pH levels and sensory property values during storage. Furthermore، shelf-life did not exceed more than 7 days in control samples while it lasted up to 35 days in yoghurt samples containing carrot juice.
This study was conducted to prolong the period of validity of diluted yoghurt by adding 0.5g, 0.75g and 1g of garlic per 1liter milk during the storage period of 50 days at 4 ± 1C °and 10 ± 1C°. Some of microbial, chemical and sensory parameters o f yoghurt were identified on weekly bases from 1 till 49 days of the storage period. Results indicated that the vital force as a microbial parameter was lasted for 7 days in the control samples while it was lasted with for 35, 42, and 49 days for the samples containing 0.5, 0.75 and 1g of garlic, respectively when samples stored at 4±1C°. There were no significant differences in the vital force between control and treated samples when they stored at 10±1C°. Sensory properties of diluted yoghurt were more favorable in samples containing 0.5g of garlic (absence of taste and smell of garlic) in comparison with control samples or with samples containing higher proportions of garlic. Results also indicated that adding garlic did not affect either the pH of diluted yoghurt or the values of its sensory properties during storage periods and increased the safety of consumption up to 49 days of storage while this safety did not extend behind 7 days in control samples. It was concludes that adding garlic by 0.5 g/ liter of diluted yoghurt can increase its shelf life for 49 days.
The object of this search was the setting up of study of sterilized milk munofactore in Syria, and definition of causes to drop of quality and decrease of shelf-life. As will as study of factors affecting the shelf-life of sterilized milk and possibility of using of the new techniques in extension of sterilized milk's shelf-life for increment of the economic yield and the competition in the markets.
The Roller Compacted Concrete (RCC) offers a different concept in the creation of pavement and concrete dams it’s dry Beaton (Zero Abrams slump), with a low water content, and includes of dense mix consisting of graded coarse aggregate, and cementati ons materials, and water, this makes it so difficult to compact it in big thicknesses layers without using large energy rollers compactors. concrete conveys by trucks, placed and compacted by using equipment asphalt pavement. The main advantage of this technique is in reducing the completion time and cost savings in labor and the possibility of replacing traditional materials in road paving. It also provides a solid surface smooth and polished, and would facilitate the operations of traffic expected in all circumstances and various factors such as axial loads and environmental conditions. This paper presents a new technology for the manufacture of Roller compacted concrete samples by applying a mechanism of Vibro-compaction pressure on samples of fresh concrete. It had Been manufactured concrete samples differ from their limestone filler content, and after conducting an analytical study of the results of tests of these samples has been reached to ideal feller content for this type of concrete by reliance on the mechanical strength and speed of evolution with time as criteria for the basic design.
