Response of Tobacco Cultivars (Burley 21 and Virginia VK51) to EMS on the Biochemical Characteristics under Drought Stress Conditions
Get PDFThe experiment was carried out during the seasons 2021/2022. To study the effect of soaking seeds with EMS in improving the tolerance of two tobacco varieties (Burley 21 and Virginia VK51) to drought stress. The seeds were treated using three concentrations of the mutagen (0.1, 0.5 and 1%) with a soaking time of (8) hours. In addition, to induce drought stress, polyethylene glycol (PEG) was used at concentrations (15, 30 and 45%). The experiment was conducted according to a randomized complete block design (R.C.B.D.) with three replicates at the Damsarko farm- Lattakia- Syria. Some characteristics (malondialdehyde, poly phenols, total soluble sugars and Nicotine content in leaves) were studied. Treatment with EMS at a low concentration (0.1%) led to an decreased in the malondialdehyde, poly phenols, total soluble sugars, Nicotine Content. However, High concentration of EMS at (0.5 and 1%) caused an increase in the studied indicators of two tobacco varieties. High concentration with PEG, caused an increase in the malondialdehyde, poly phenols, total soluble sugars, Nicotine Content. More clearly with increasing applied stress. Thus, it can be suggested to soak seeds at the concentration (0.1%) EMS for its role in improving some characteristics of tobacco under drought stress conditions

Exploring the Potential Use of Orangepeel Powder to Obtain Arabic Bread with High Nutritional Characteristics
Get PDFThe orange peels that are resulting from the orange juice factories are considered a promising by-product in the field of the food industry. Arabic bread is a staple food in many Asian countries, and incorporation of the by- product food industry, like orange peel powder (OPP), definitely improves its health benefits. This work optimized a formulation based on wheat flour and OPP with technical feasibility. So, Arabic bread prepared from blends with different levels (2.5%, 5%, 7.5%, 10%) of OPP evaluated for rheological properties, as well as sensory and chemical properties. The addition of OPP resulted in significant changes in wheat dough alveograph parameters, as evidenced by the increase in values of (P/L), whereas the reductions in (W) values. Measurements by Mixolab apparatus showed that water absorption capacity and dough development time increased as the amount of OPP increased (from 54.7% to 62.3% and from 1.45 min to 4.42 min), whereas dough stability showed a reverse trend (decrease from 8.58 min to 7.23 min). On the other hand, retrogradation characteristics improved when adding a low content of the powder. At another level, the chemical composition of Arabic bread values showed a higher percentage of moisture, ash, crude fiber, lipids, phenolic content, and antioxidant capacity with increasing the level of OPP, but protein and carbohydrate contents decreased with increasing OPP concentration. Overall, the 2.5% OPP addition rate gained acceptance when conducting the sensory evaluation

A Study of Physical Properties Related to the Technology of Manufacturing Double-layer Flatbread in Syria
Get PDFPhysical parameters play an important role in the technological process of manufacturing popular double layer flatbread bread in Syria, and it was found that knowledge, professional experience, and adherence to them contribute mainly to shaping the physical characteristics of the resulting loaf. Given that these parameters are directly related to the method of executing the technological processes used during the process of making bread (mixing and kneading the ingredients, dividing and sheeting the dough, resting the sheeted dough to complete the final fermentation process, the conditions controlled within the baking chamber of a suitable temperature for baking, and the quality of heat distribution), the research objective was through a field study to shed light on the differences that appear in the process of manufacturing popular bread, and its impact on the physical properties of the resulting loaf. Thus, using parameters in a modeling process in order to obtain the most appropriate data, and employing them to obtain a loaf with good sensory characteristics.
It was found that the craftsmanship of the work of the crew executing the manufacturing process is reflected in the physical properties of the resulting loaf, and the abnormal variation in the values of these characteristics can be adopted as evidence of the inefficiency of implementing the technological processes in the bakery, and thus working to re-correct the implementation of these processes.
The relationships between the physical parameters (bread parameters such as the weight of the whole loaf (g), the weight of the upper section (g), the weight of the bottom section (g), the specific volume of the upper section, the specific volume of the bottom section, the specific volume of the upper sheet, the specific size of the bottom sheet and the specific volume of 100 g of dough) with the help of mathematical statistics, using regression analysis between bakery data through mathematical equations (at one end of the equation is an independent variable and at the other end a dependent variable), which take the linear, quadratic, cubic, exponential, power or logistic form, which It means that the dependent variable can be predicted by knowing the value of the independent variable with very little error.
The best mathematical equation that describes the relationship between the independent variables and the dependent variables adopted within the research was the power relationship of the form, and it is remarkable that it applied to the description of the results of all bakeries, and the adjusted coefficient of determination was very high, with more than 0.99 for all cases. Depending on the mathematical model represented by the equation, the output of the baking process can be set based on the choice of inputs with high reliability
