Abstract

As Syria enters its eleventh year of the crisis, the problem of food insecurity has increased, and become a very important issue at the local and global level. The aim of this research is to measure the farm households’ food security status in the coastal area, using a set of internationally approved measures, which are the Food Consumption Score (FCS), the Reduced Coping Strategies Index (rCSI), and the Food Security Index (FSI). The research relied on collected preliminary field data using a questionnaire form during last quarter of 2019, the research was conducted on a random stratified sample of 382 farm households distributed between Lattakia and Tartous governorates based on their percentage of the total number of households. The results showed that FCS gave the lowest level of food insecurity among households, followed by the FSI, while rCSI gave the highest level of household food insecurity, where the value of these three indicators was (20.6, 21.6, and 47.2%) respectively. The study recommended the necessity of using multiple indicators to measure the different dimensions of food security, and using a combination of indicators can improve the measurement of food insecurity, as this reduces the false possibilities, whether positive or negative and the misclassification of households’ food security status.

Abstract

The research was carried out during the period 2016-2020 to collect, characterize and cultivate some of the Syrian wild strains of oyster mushrooms found in the southwestern Hama region. Several wild Syrian strains of the oyster mushroom Pleurotus spp. were collected, cultivated and their productivity and chemical composition were studied compared to a control (a locally cultivated commercial strain M2175 of Mycelia company of Belgium) in a completely randomized design. The studied six strains (S5, S7, S11, S13, S15, S17), were collected from locations with altitude that ranged from 419.71 to 813 m above sea level, morphologically described, then isolated and purified on PDA, and then cultivated on wheat hay after preparing their spawns on durum wheat grains. After harvesting, readings related to the fruiting body (and fruiting clusters productivity and biological efficiency were calculated. The chemical content of fruitbodies was studied. The results showed a good level of spread and ecological diversity of the fungus, with wide variations between the collected strains in terms of their morphological characteristics, especially in the color, shape and diameter of the cap. The dimensions of the spores ranged between (3.41 and 4.35) microns in width and (8.52 and 10.85) microns in length, while the strains did not differ in the nature of their lateral fruiting on the host’s trunk and inward rolled margin of the cap. The results of strains cultivation on wheat hay indicated that there are clear differences between them in the indicators of fruitbodies growth and productivity, where the average diameter of the cap ranged between 7.57 and 10.74 cm, the average diameter of the stem 1.45-2.40 cm, the average length of the stem 1.70-3.40 cm, and weight of fruitbody 20.2-54.36 g. The average number of fruitbodies of the studied strains per cluster ranged between 9.40 and 28.20, the average number of clusters ranged between .3.33 and 4.67 clusters, the average weight of the fruit cluster ranged between 336. and 503.8 g, the average productivity ranged between 232.25-326.73 g/kg, and the value of biological efficiency varied between 87.11-110.43%. Analysis of the chemical content of studied strains showed significant differences, S17 and S13 characterized by a high content of dry matter and protein, and the S17 also had a high content of ash, fat and fiber. The strain showed good protein content of 19.12-33.36%. The highest content of fiber was in the S5 and S17 strains (22.17 and 19.51%, respectively). As a result, all strains were good. S13 and S17 were selected as the best strains in terms of the most important productive and quality characteristics.

Abstract

Gum is one of the complex carbohydrates that formed in the different parts of plants. It is characterized by its low cost of production, as well as being one of the additives that are currently taking a lot of attention due to its properties. The purpose of this research aims to study the chemical composition and some physicochemical and functional properties of the mucilage extracted from two types of jujube fruit : Cultivated jujube (Z. jujube), Wild jujube (Z. lotus). Moreover, to test the efficiency of produced mucilage by using it in some food products, analyze its effects on the sensory properties of the studied product and compare these affected properties when using imported commercial gums (Arabic gum was used for comparison purpose). This study was carried out with cooperation between Tishreen University and General. The analysis of chemical composition of the studied gums showed that their content of carbohydrates is in high level. It was (85.85%) for Arabic gum, (87.57%) for Z.lotus, and (89.83%) for Z .jujube. While the proportion of protein and ash were low, and the fat content was almost equal to zero for the three studied types of gums. For the sensory evaluation, creamy ice cream sample tested by adding Z. lotus mucilage had the highest grades, and its sensual properties like shape, textures, color, flavor and resistance to Solubility were the best compared to the samples tested by adding Z .jujube mucilage or Arabic gum. These results indicate that the mucilage extracted from both mentioned types of jujube can be used as stabilizer in  the field of food industry and as an alternative to high-cost imported commercial gums.
