Abstract: In this study, essential oils extracted from Umbelifera family plants (cumin, aniseed, fennel, and caraway) have been extracted by using microwave - assisted water distillation and traditional water distillation (Clevenger method).The results showed that the needed time to extract essential oils from seed by microwave - assisted water distillation was significantly less than Clevenger method. The results also showed that the higher oil yield extracted from cumin, aniseed, fennel, and caraway by microwave - assisted water distillation were 4.8, 1.3,7, 3.4 and 2.8 % respectively, while by using Clevenger method were 4.5, 2.8, 2.3 and 1.3 % respectively. As noticed that higher oil yield was from cumin compare with other studied oils.Physical properties have been studied of extracted oils by microwaveassisted water distillation and Clevenger method. The results revealed that oils extracted by the two methods were dissolved into alcohol and did not dissolve in water. Also, colors of extracted essential oils ranged between yellow to yellowish brown. Caraway oil was yellow gold, cumin was yellowish. In addition, the taste of fennel oil and aniseed was sweet contrary to cumin and caraway oils were bitter. Specific density of all essential oils extracted by microwave - assisted water distillation and Clevenger method in this study ranged from 0.64 - 0.92. Refractive index values of extracted essential oils by Clevenger ranged between 1.48 - 1.55, and 1.49 - 1.55 by microwave - assisted water distillation. In terms ofabsorbency, the better absorbency was at microwave - assisted water distillation and Clevenger method at wave length of 280 nm compare with other oils that appeared better absorbency at wavelength of 250nm. Antioxidant activity has been measured of different concentrations of the four essential oils extracted by microwave - assisted water distillation and Clevenger method. Also, the results showed that antioxidant activity of linoleic acid of essential oils was converging for both methods Antioxidant activity was increased with increasing essential oil concentration, and the concentration of 100% had gave higher value of antioxidant activity of oils extracted from cumin, aniseed, fennel, and caraway by Clevenger reached 60 ، 69،78%respectively, also reached 65, 74, 59, 68% respectively for essential oils extracted by microwave - assisted water distillation . Also, the results showed that antioxidant activity of caraway oil was significantly higher than other essential oils. The abilityof different concentration from the four essential oils extracted by microwave - assisted water distillation and Clevenger method has been studied in the growth inactivation some types of pathogenic bacteria such as Escherichia coli, Pseudomonas aeroginosa and Staphylococcus aureus where noticed that activity of essential oils was increased with increasing oil concentration and the higher inactivation of oils was at 100% concentration. There is a variation in activity of all essential oils toward Bactria types. Caraway has high inactivated effect compared with other oils in this study and inactivation diameter of oil caraway extracted by Clevenger at concentration of 100% reached 19, 28, 32 mm toward testing Bactria of Staphylococcus aureus، Escherichia coli and Pseudomonas aeruginosarespectively, while average inactivation of this oil extracted by microwave - assisted water distillation was less compare with Clevenger where reached 30, 25, 16 mm towards cited Bactria types respectively. The results also showed that the identification of activation chemical compounds that is present in the essential oils xtracted by Clevenger and microwave - assisted water distillation using GC - MS technique for acknowledgment its quality, quantity and percentage in the four essential oils as follow : 1. The results of identification of active compounds of essential oil caraway extracted by Clevenger and microwave - assisted water distillation have been demonstrated Carvon compound by high ratio reached 47.12 and 40.5 % for both extraction methods respectively, while compound ratio Anethol and D - Limonene of caraway oil extracted by Clevenger were 16.18 % and 11.67% respectively and by microwave - assisted water distillation were 22.19% and 10.96% respectively.2. The chemical compounds like Alpha - Isopropylbenzyl alcohol, Cumic aldehyde and betapinene extracted from cumin essential oil by Clevenger reached 35.19, 22.60 and 13.26% respectively, while reached 33.77, 21.24 and 13.26% respectively by using microwaveassisted water distillation. On the other hand, the compound of Alpha - Isopropylbenzylalcohol has higher concentration compared with other prevailing compounds in extracted oil by these two methods.3. The results showed that the appearance of chemical compounds in aniseed oil extracted by Clevenger and the higher ratio was registered by Anethol compound reached 75.33% compared with other prevailing compounds, also the appearance of the samecompound with high ratio reached 77.58% in the extracted oil by microwave - assisted water distillation.4. The prevailing compounds in the essential oil of fennel extracted by clevengerwere Anethol , L - Fenchon and Estrago by 72.78, 7.41 and 5.52% respectively, while their ratio reached 67.01, 8.28 and 4.93% respectively by using microwave - assisted water distillation.From these results, the Anethol compound was prevailingcompound in the two extraction methods.

Abstract: Research efforts were directed to the production of - environment - friendly and edible - biological materials to be used in food packaging from protein soybeans. The research also included the impact of oil and wax sorghum extracted as by - product of sorghum grain and sugar glucose on the films properties. This study included three points of discussion.First, Concentrated soy protein was extracted from soybean grains in the form of a yellow fine powder. Its chemical composition was studied and found to contain : protein and fat and ash and moisture and carbohydrates respectively (71.5 , 0.78 , 4.9 , 8.4 , 14.4)% . Also, oil and wax sorghum has been extracted from sorghum grain.Second, concentrated soy protein and glycerol were used as major raw materials in addition to other materials like sorghum wax and oil and glucose were used in the preparation of the edible films in the form of thin layers. The physical, mechanical and thermal properties of this edible film were studied and the results were as follows : 1. The simple soy protein films - without plasticizer - were fragile and difficult to handle. On the other hand, the soy protein films with 4%, 5% and 6% concentrations with 40% from protein weigh glycerol as plasticizer were easy to remove from the plates. Particularly, 5% and 6% concentrations were easier to remove from plates than 4% concentration which was difficult to handle. In general, films were shiny, flexible, transparent, smooth yellowish, has no taste or odor and the presence of free bubbles was noted. It was also noticed that with increased protein concentration from 4% to 6%, the film thickness increased from 0.08 to 0.098 mm, the tensile strength increased from 2.15 to 3.3 MPa, the elongation percentage decreased from 140.0 to 81.7%, the water solubility ranged from 45.9 to 35.0% and water vapor permeability values rose from 8.8 to 9.6 g. mm / m².hr.KPa with a higher concentration of soy protein from 4 to 6%.The first stage from Thermal disintegration begins at a temperature of 116 ºC due to the loss of moisture. The second stage of disintegration starts at temperatures of 190 ºC and attributed to the disintegration of glycerol when the maximum temperature is 289 ºC. While the third stage of disintegration starts overlapping with thedisintegration of the glycerol at a maximum temperature of 385 ºC and attributed to the disintegration of soy protein.2. The complex 5% soy protein films with 2% glycerol plasticizer and sorghum oil or wax concentrations of 0.2%, 0.4% and 0.6% (weigh/ volume) was found to be characterized by flexibility, smoothness, and easily removed from plates. In addition, it was less transparent and acquired the color of lipid and increased thickness with high wax or sorghum oil concentration. It was also noticed that water solubility has ranged from 38.2 to 32.4% and tensile strength has decreased from 2.5 to 1.1 MPa and elongation percentage has increased from 125% to 138% and water vapor permeability has decreased from 8.9 to 8.6 g.mm / m².hr.KPa with increasing concentration of sorghum oil. On the other hand, it was observed that water vapor permeability has decreased from 8.1 to 6.9 g.mm / m².hr.KPa and water solubility has decreased from 37.2 to 35.2% but the tensile strength has increased from 2.42 to 2.52 MPa and elongation percentage has decreased from 115 to 95% with a increasing concentration of sorghum wax. There are no differences in the thermal decomposition of the films protein complex with oil and wax sorghum compared to simple films protein from soybeans.3. The complex 5% soy protein films with 2% glycerol plasticizer and different concentrations of glucose; 1% and 1.5% and 2%(weigh/ volume) was characterized with sheen, smooth and polished surface with acceptable flavor and brown color. It was also easy to remove from plates but less flexible that simple soy proteins. It was also observed that the thickness of the films was increased from 0.088 to 0.091 mm and water solubility was decreased from 41.2 to 40% and the water vapor permeability was decreased from 8.98 to 8.77 g. mm / m².hr.KPa while the elongation percentage has reached 90%, 92% and 115% and the tensile strength has decreased from 2.7 and 2.3 MPa with increasing glucose concentration. It was also noted that the thermal decomposition this complex is more stable compared with simple films from soy proteins.Third, concentrated The application of the obtained biofilm in Food system : 1. Practical applications were conducted by using solvents of simple and complex soy protein films compound with sorghum oil in covering pear fruit for protection. As a result, the fruit was characterized by glossy, transparent colorless polished smooth and softer texture. The fruits covered withcomplex membranes have the same characteristics but less glossy. This method has extended the shelf life for the fruit by 15 days because of the limited moisture loss change in acidity level (pH) compared to not covered fruits at a temperature (4 - 6ºC) The fruits covered and stored at room temperature are more acceptable compared to non - covered fruits.2. Another application is to use soy protein films - simple and complex - with glucose in the coating of the fish pieces and when stored for a week at refrigerator temperature, the results were higher values of peroxide number for un - coated fish reached 6.2 milli - equivalent / kg compared with the coated pieces with simple membranes reaching 4.8 milli - equivalent / kg and for coated with composite film with glucose peroxide number value reached4.3milli - equivalent/kg. .

Abstract: This study was carried out to produce animal gelatin from the secondary wastes of chicken and camels. The studied gelatin from chicken heads and legs and camel bones. Gelatin was prepared by the chemical method and the chemical composition, yield, functional and sensory characteristics were measured at storage periods of 0, 20, 40 and 60 days under refrigeration at 4 - 8 ºC. The produced gelatin was introduced into the food systems where it was used to prepare beef burger as an alternative for fillers. The results showed that the highest gelatin yield 8.04 % was produced from chicken waste with no significant difference from 4.60 % yield of camel bones.The results of the chemical composition (protein, lipid, ash and moisture) for the crude gelatin indicated that it contain high percentages of protein which differ significantly according to the source, so as for the other components. Lipid percentage have increased notably in chicken gelatin and reached 3.89 % in comparison with 0.82 % in camel gelatin while the latter was featured by high ash content which reach 5.865 % in comparison with 3.48 % in chicken gelatin.The results also demonstrated that the produced gelatin have good functional properties in solubility, viscosity, gelling capacity, water absorption, lipid binding, emulsification and foaming. Water absorption capacity was higher in chicken gelatin in comparison with camel gelatin and reached 0.90 and 0.48 ml / g , respectively. On the other hand, lipid binding ratio increased in camel gelatin to reach 2.21 in comparison with 2.0 ml oil / g gelatin in chicken gelatin. The two gelatin types were featured by high gelling capacity at 1% for all storage periods where the gelling of camel gelatin was faster and stronger.The produced gelatin was characterized by good sensory qualities (color and odor). Chicken gelatin have a creamy color while camel gelatin have a pale creamy color. The two types of gelatin were featured by being odorless. The produced gelatin was used into food systems by preparing burger which have good sensory quality as shown by good score in the sensory evaluation of flavor, juiciness, color, tenderness and general acceptance.Storage period had no significant effect on the properties of the two types of the produced gelatin as for the chemical composition, functional and sensory characteristics. For the chemical composition, the various chemical components were noticed to increase slightly on behalf of moisture reduction. The functional properties did not influenced largely by storage and the produced gelatin preserved good qualities along the storage period.The results of gelatin amino acid analysis demonstrated that it contained 18 amino acids, the highest concentrations were for Aspartic acid and Threonine in chicken and camel gelatin , respectively. The amino acid Leucine was the lowest in both types of the produced gelatin.The results showed a variation in mineral contents for calcium, magnesium, cooper and iron between gelatin types. Calcium concentration was observed to elevate in chicken gelatin to 125 μg / g dry weight, while it reached 87.5 μg / g dry weight in camel gelatin. An elevation in iron concentration was noticed in camel gelatin in comparison with chicken gelatin with concentrations of 20 and 10 μg / g dry weight, respectively while the two gelatin types were devoid from lead and cadmium.

Abstract: This study was conducted to investigate and test the activity of three essential parts of wheat seed Aleurone, germ and bran which were used as secondary products from grinding grain to feed animals. diversity solvents (distilled water, chloroform, hexane, ethanol, methanol) were applied to extract the bioactive compounds by both traditional and modern extractions.The total phenolic compounds, antioxidant activity, reducing power, metal chelating, and scavenging of hydrogen peroxidase were determined for all three essential parts of wheat. The stability of the extracts was studied toward temperature and pH at the interval time. In addition, the synergistic effect of the extracts was studied by mixing with different concentrations of ascorbic acid and alpha tocopherol. The extracted compounds were identified using gas chromatography mass spectroscopy (GC - Mass).The ethanol extraction of wheat germ had the highest antioxidant activity, so it was chosen to prevent oxidation in the corn oil. Moreover, the ethanol extractions for germ, bran and Aleurone were added to wheat flour (80 % extraction) in order to study their effects as improvers in the rheological properties of wheat flour dough. The results were as follows : 1 - The microwave - assisted extraction for 40 sec was able to extract the highest level of phenolic compounds from wheat germ compared toconventional extraction conditions. The total phenolic compounds were 556.6 μg gallic/ml, 426 μg gallic/ml for ethanol and methanol extractions, respectively.2 - The microwave - assisted extraction was able to give the highest antioxidant activity (53%) at concentration of 100 mg/ml from ethanolic wheat germ extraction compared to synthetic antioxidant BHT ( 92 %). In addition, the wheat germ had the highest reducing power (163.88 %) at concentration of 5 mg/ml , while the percentage of reducing power for both ethanolic extraction of Aleurone and ethanolic extraction of wheat bran were 112.63 % and 79.68 %, respectively. In contrasts, all of above extractions had lowest reducing power compared to BHT and alpha tocopherol 249.8 % and 223.5 % respectively at the same concentration. Moreover, the wheat Grem had the highest percentage for both Ferrous chelating and scavenging of hydrogen peroxidase.3 - Ethanolic extracts of Aleurone, bran and germ have a higher antioxidant activity in natural pH while decreased when treated with acid and alkaline. In addition, the ethanolic wheat germ was able to give the highest antioxidant activity at 100°C for 100 min wich read 62.2% compared to others and gave synergistic effect for bothascorbic acid and alpha tocopherol exhibited 91.90 % of antioxidant activity at concentration 60 mg/ml.4 - Identification of ethanolic and methanolic extract using GC/MS showed presence of bioactive compounds such as ascorbic acid, benzoic acid, phytosterol compounds, Isoeugenol and alkylresorcinols5 - Ethanolic extracts of germ with concentration 0.05, 0.10, 0.15, 0.20, 0.25 mg/g was added to corn oil in order to compared with BHT 0.05% and stored at 45°C for 28 days, the result showed that the ethanolic wheat germ at 0.25 mg/g had the ability to decrease the hydrogen peroxide for the corn oil 6.8 meq/kg at end of stored time compared BHT (0.05 %) 4.3 meq/kg at the same conditions.6 - The ethanolic Aleurone extraction possessed a positive effect on the rheological properties when it was added as improvers to the wheat flour ( 80 % extraction). The dough consistency was 6.7 min, which considered highest reading among all treatments. In addition, the recorded elastic index was 3.2, 2, and 1.8 at interval times 45, 90, 135 min, respectively.

Abstract: Forty three local bacterial isolates were obtained after heating treatment for different sources collected from many places in Basra government. Included : Vegetables, Fruit, Pastry (cakes), Legumes, Soils, Sand, Animal manure, the papyrus plant, milk, water liquefaction and sewage water. Primary screening for the isolates by Sudan black B dye only. 22 isolates were chosen with strong staining, and the identification of all the isolates revealed were belong to genus Bacillus by studying microscopic and biochemical tests. They were : 4 isolates Bacillus cereus, 2 isolates Bacillus firmus, 2 isolates Bacillus lichenformis , 3 isolates Bacillus megaterium, 4 isolates Bacillus mycoides , 3 isolates Bacillus pumilus and 4 isolates Bacillus subtilis.Secondary screening of these isolates was Polyhydroxybutyrate (PHB) produced, Bacillus cereus B5 given 2.4 g / L the highest production of PHB. A PCR technique was used for 16S rRNA test and detecting the gene of PHB production in Bacillus cereus B5.The highest PHB production from Bacillus cereus B5 was 6.2 g / L, biomass 8.4 g / L and yield 73.8% the by using optimum conditions : incubation temperature 35̊ C, for 48 hours aerobically by using shaking incubator for 150 RPM/ min, 2% inoculum volume, the pH was adjusted to 7, and the production media where contained 1% glucose as carbon source and peptone as a nitrogen source. 3% have dated juice was the best substitute for glucose as carbon source, it gave 7.11 g PHB / L and the yield 79 %.Analysis with FT - IR was showed, that PHB produced from date juice media had a peak at 1723 cm - 1 this means it belong to an esterpolymers group. And GC - MS showed 12 compounds produce from analyzing PHB as short chains of fatty acids.The properties of PHB produced from date juice media were : The degradation temperature was 312̊ C, the percentage of crystallization was 60%, molecular weight was 423.674 KDa., permeability of water vapor was 56.2 ×10 - 8 g / Pa.s.m2, tensile strength was 24.9 MPa, the blend 40% polyethyleneglycol as plasticized with PHB increased the percentage of elongation to 8.7%. PHB is non - toxic and without hemolysis on human blood.Studying biodegradation of the plastic films of PHB by using bacterial isolates were E. coli, Pseudomonas aeruginosa, Staphylococcus aureus and Bacillus cereus in petri dish showed that all isolates can degrade PHB, biodegradation in soil and at soil surface was 100% after 28 days.PHB packages increased the shelf life of strawberries and grapes after storage for 15 days, compared with polyethylene packages, and It was reduced the numbers of microorganisms in butter, the percentage of free fatty acids and peroxide value compared with butter with polyethylene after 15 days
