In this study, a total of 364 samples were collected and 349 of them belonged to, 349 specimens of Dasyatis pastinaca, 6 of Gymnura altavela, 5 of Torpedo marmorato, 2 of Aetomylaeus bovinus and Mustelus mustelus, were obtained by-catch in trammel nets off the Izmir Bay (Aegean sea coast of Turkey) during period of spring in 2018. Males of D. pastinaca ranged from 28–62 cm and females from 31.5-94 cm total length. The analysis of the angular coefficient (b) demonstrated that growth (in weight) in relation to length was isometric in males and females of D. pastinaca. Morphologic measurements of a total of 60 individuals to represent all individuals of the population, t test in independent groups to determine differences in males and females and all other morphometric measurements were statistically tested by multiple regression analysis (stepwise method). Therefore, difference between mean values obtained according to sexes was not found different. However, A linear correlation between weight- pelvic length for females and weight- preanal length for males according to multiple regression analysis in male and female individuals. Isometric and positive allometric growths were calculated for species of Torpedo marmorata and Gymnura altavela, respectively.

The objective of the present study was to determine the relationships between animal welfare score (AWS) and milk somatic cell count (SCC) in Anatolian buffaloes. The study carried out on 39 buffalo farms of Bafra district of Samsun province of Turkey between January and March 2020. To obtain AWS data, a scale with 1 to 100 points (1-25: poor, 26-50: moderate, 51-75: suitable and ≥76: excellent) was used. Locomotion ability (LA), social interaction (SI), flooring (F), indoor conditions (IC) and effect of stockman (S) were used to be AWS parameters. Milk samples were analyzed by SCC using a portable cell counter. The SCC values were transferred to log10 base before the analyses. To assess the effects of AWS on logSCC, independent sample t-test was performed. The relations of all parameters with each other were calculated by Kendall rank correlation method and the statistical analyses were carried out by SPSS 17.0. The highest and the lowest means were obtained from SI (79.66±1.28) and F (61.79±2.51), respectively. While the highest correlation was estimated between IC and AWS (r=0.724), all AWS parameters had approximately moderate relations with AWS. Positive or negative, but insignificant correlation coefficients were estimated between any traits and logSCC. The means of SCC (136841±15522 cells/ml) and AWS (68.70±1.67) of the present study were found within the suitable thresholds. Routinely keeping the records on AWS and its components, and adding AWS data to the herd management programs was suggested to the buffalo farm owners.

Peanut allergens adversely affect the health and quality of life of millions of consumers worldwide. The seeds of the peanut plant (Arachis hypogaea L.) contain a number of allergens that trigger the production of specific IgE antibodies in allergy-prone individuals. Currently, 18 proteins found in peanuts are accepted as allergens. These allergens are named from Ara h 1 to Ara h 18. Ara h 2, Ara h 6 and Ara h 7 are from albumin, Ara h 1 and Ara h 3 are from globülin. Ara h is the abbreviation of Arachis hypogaea, the Latin name for peanut. A peanut allergy is a reaction that occurs shortly after eating to peanuts or peanut products. It has various symptoms that can go up to swelling of the tongue, itching of the palate, itching and burning in the throat, itching in the eyes and nose, nausea, vomiting, abdominal pain, shortness of breath, wheezing, bruising, chest pain, hives, low blood pressure and shock. In this review, the properties of peanut allergens and the methods of reducing the allergen effect will be reviewed.

Yeast cells are carriers with great potential for encapsulation of both hydrophobic and hydrophilic compounds, due to protection from external environmental influences, controlled release, biocompatibility and biodegradability. The promising research results on the encapsulation of bioactive substances in the recent past promise a bright future in many fields such as agriculture, medicine and cosmetics, including functional food. The significant decrease in the stability of many bioactive compounds due to environmental conditions (heat, humidity, oxygen, etc.) has revealed the necessity of preserving the stability of these types of compounds by encapsulation process. After the recognition of yeast cells as suitable carriers for water-soluble flavor encapsulation, the possibilities of using various yeasts, especially Saccharomyces cerevisiae, in the encapsulation of various oils, vitamins, flavors and some phenolic compounds have been the subject of various scientific studies. The fact that the encapsulation process using yeast cells offers some advantages compared to other encapsulation methods has made the use of yeast cells in the encapsulation process very popular and there has been an increase in studies conducted in recent years. In this study, various scientific studies on the possibilities and effectiveness of the use of yeast cells in the encapsulation of various structures, especially various bioactive compounds, have been reviewed.

In this study; The effects of using urea as top fertilizer and "Nutrisphere-N-Urea" fertilizer, which is a nitrogen stabilizer, on some yield and quality criteria of bread wheat and corn were investigated. Experiments were carried out in the fields of the Eastern Mediterranean Agricultural Research Institute according to a randomized block design with four replications. In the wheat trial; control (no fertilizer), conventional-DAP (15 kg/da)+Urea (29 kg/da), DAP (15 kg/da)+Nutrisphere-N-Urea (15 kg/da) and DAP (15 kg/da)+Nutrisphere-N-Urea (29 kg/da) subjects including were studied. In the corn trial; 25 kg DAP/da+without top fertilizer; 25 kg DAP/da+60 kg Urea/da and 25 kg DAP/da+60 kg Nutrisphere-N-Urea/da were the subject of the research. As a result of the observations and analysis of variance, the effect of the use of "Nutrisphere-N-Urea" on yield and yield criteria in wheat, despite the classical top fertilizer (Urea) application, was found to be statistically significant. While the yield per decare was 326.88 kg in the traditional application, it was found to be 388.46 kg when Nutrisphere-N-Urea (15 kg/da) was used. In the corn trial; While the effect of the use of "Nutrisphere-N-Urea" on plant height, first ear height and hectoliter weight was found to be statistically insignificant compared to the control subject, it was seen that it caused statistically significant differences on stem diameter and yield values. The highest yield (1774.31 kg/da) and crude protein (8.95%) and low starch ratio (67.73%) were obtained from the “25 kg DAP/da+60 kg Nutrisphere-N-Urea/da” application.

Propolis is a resinous substance produced by bees that is rich with phenolic and flavonoid compounds. Extract of propolis has a high antioxidant and antimicrobial properties due to the presence of these compounds. Therefore, the main objectives of this study were to examine the antibacterial and the antioxidant activities of standardized, commercial water extract of propolis in vivo assays, and to assess its impact on preservation of raw beef meatballs aerobically packaged and stored at 4ºC for 7 days. The results showed that the propolis extract demonstrated the highest antibacterial activity against Staphylococcus epidermidis in vivo test. Furthermore, meatballs prepared with the propolis extract had an extended shelf life about a week in comparison to the regular meatballs. Besides, the propolis extract was a very effective natural antioxidant agent for controlling the oxidative changes in meatballs. The propolis treatment provided 64.6% reduction in the malondialdehyde formation at the final day of storage. Color lightness and yellowness values of meatballs were not affected by the propolis treatment, only difference was observed in redness values. The pH of the meatballs prepared with the propolis extract almost stayed constant during storage, while the pH of the control meatball samples increased. In summary, propolis extract exhibited a strong antimicrobial and antioxidant activity in vivo assays and in a meat product. Accordingly, it should be used in meat product formulations to enhance preservation of meat products.

This study aims to reveal the quality properties of yogurt enriched with walnut during cold storage (4°C) for 28 days. Five sets of yogurt types were produced by using walnut at varying rates (A: 0% (control), B: 1%, C: 2.5%, D: 3.5%, E: 5%). Physicochemical, sensory, phenolic contents and antioxidant properties of yogurt samples was investigated during the 1st, 7th, 14th, and 28th days of storage. The study was conducted to optimize the walnut addition level to obtain better quality yogurt as a functional food. It was determined that the walnut enrichment affects the gross chemical component of yogurt samples. Yogurt sample with %5 walnuts (E) had the highest total phenolic and antioxidant activity content (respectively 1027.50 mg GAE/kg, 19.95 mM TE) among the samples. The yogurt sample with the highest sensory attribute score was the one containing 1% walnuts. Therefore, it was concluded that yogurt added with walnut could serve as functional yogurt beneficial for human health.

Moringa oleifera Lam. is one of the most used plants in traditional medicine because of its high antioxidant properties. The antioxidant value, nonetheless, depends on locality where the plant is grown as well as specific parts on the plant. In this study, a phytochemical and antioxidant activity comparison of M. oleifera leaves, seeds and barks were carried out. Fresh leaves, seeds and barks were collected from 2 to 3 years old M. oleifera trees of Bukavu city of South Kivu province in DRC and Masii village of Machackos County in Kenya. A total of 300g of each dried sample powder was mixed with 700 mL of distilled water. Qualitative and quantitative assessment of alkaloids, saponins, phenols, flavonoids, glycosides, terpenoids and tannins were performed following standard methods while the antioxidant activity was assessed using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. Results indicate that only alkaloids were absent in leaves from Kenya and DRC while phenols, flavonoids and tannins were absent in barks. Glycoside in seeds from DRC had the highest concentration (6.17%) followed by alkaloids in seeds from Kenya (5.56%). There was low concentration of terpenoids and flavonoids in all samples compared to other compounds. The highest extract yield was found in leaves from DR Congo (22.5%) and seeds from Kenya (20%). At the highest concentration (10 µg/mL), leaves from Kenya (88.29±1.12 µg/mL) and DRC (80.17±3.59 µg/mL) had the highest percentage inhibition of reactive oxygen-free radicals but lower than the reference standard (92.63±2.76 µg/mL). Leaves from Kenya (23.59 μg/mL) and DRC (28.67 μg/mL) had the highest IC50 compared to mean values of seeds and barks from the two countries. M. oleifera leaves, especially from Kenya, are recommended as a satisfactory antioxidant but can be substituted with seeds and/or barks in order to alleviate the use of leaves which are overused these days.
