Meral Kekeçoğlu | Tuğçe Çaprazlı | Emel Çalışkan | Serpil Uğraş
In this study, we aimed to determine the therapeutic value of local Yığılca honeys by examining their physicochemical characteristics, phenolic content, radical scavenging activity, and antimicrobial properties by underlining some overlooked parameters. Honey samples ware divided into two main groups as CH and FH based on melissopalynologycal analysis. Antimicrobial activity of collected honey samples were investigated on important hospital-acquired infections bacteria strains; MRSA (Methicillin-resistant Staphylococcus aureus), MSSA (Methicillin-sensitive Staphylococcus aureus), Escherichia coli, and Acinetobacter baumannii. Although CH’s antimicrobial activities were found slightly higher than the FH’s, there isn’t statistically significant differences between two type honeys. However, the antioxidant activity of CH was found significantly higher than FH. Surprisingly, a higher amount of isomaltose was determined in addition to the total phenolic content in CH compared to FH. There has been found positive correlation between isomaltose amount and zone diameters for MRSA and A. baumannii. We would like to draw attention to isomaltose for its health benefit structure since these parameters may be influence honey’s therapeutic value. We recommend that isomaltose and invertase enzyme should be included in to the honey codex standards suitably depending on the monofloral and multifloral honey’s specific structure, to sensitively standardize and control their quality and therapeutic value. Our data revealed a positive correlation between antioxidant and antimicrobial activity and total phenolic content and higher isomaltose amount.

Ayşe Bayramoğlu | Fatih Şen
This study was carried out to determine the effects of different openings onto the polyethylene (PE) packages used in storage of ‘Sultani Çekirdeksiz’ grape variety on quality, SO2 damage, pathological and physiological disorders of grapes. Grapes were harvested at full maturity and placed in PE bags with ‰0 (control), ‰0.5, ‰1 and ‰2 openings. After pre-cooling grapes in the case of SO2 pets were placed after the mouth of the bags were closed. Grapes were stored at 0°C and 90-95% relative humidity for 4 months, and quality changes were determined in monthly samples. SO2 concentrations detected at the end of storage in PE packages with ‰0, ‰0.5, ‰1 and ‰2 openings were 11.16, 5.80, 2.05 and 0,00 mg/kg respectively. It has been found that grapes in packages without opening had significant SO2 content and SO2 damage, especially the end of storage. However, grapes in packages with ‰2 openings had high weight loss and browning scores in stems. The results showed that ‘Sultani Çekirdeksiz’ grapes could be stored more successfully in PE packages with ‰0.5 openings. ‘Sultani Seedless’ grape variety, it may be suggested to use PE bags without openings for 2 and 3 months storage.

Jaydip G Kedar | Asif U Pagarkar | Nikheel Bhojraj Rathod | Taufin E Baug
Catla (Catla catla) steaks treated with sodium benzoate (SB) 0.5-2 % packed under aerobic (AP) and vacuum packaging (VP) were evaluated for biochemical, microbiological and sensory quality changes during chilled storage conditions for 27 days. The results were plotted against time, determining best fit order with corresponding regression equation to predict and compare with experimental findings. The formation of volatile amines (TVB-N) was low in samples treated with SB under VP, while no significant difference was observed in pH values. Peroxide value and salt soluble nitrogen values were significantly influenced under VP and SB treatment. Total plate count values significantly increased in all samples, but were within the maximum permissible limits. E. coli, S. aureus and Salmonella were not detected in the samples during storage. Zero order kinetics exhibited best fit for changes in biochemical and microbiological quality. Sensory evaluation scores had high correlation with storage period and low relative error (P0) for control samples under AP and VP. Therefore, combination of SB at 2.0% and VP can be used effectively as an intervention for the preservation of chilled stored Catla steaks.

Chrysophyllum albidum fruits are underutilized because they are seasonal and perishable in nature due to physiological, biochemical and microbial alteration. This study investigated the potency of calcium chloride (CaCl2) in suppressing postharvest deterioration of Chrysophyllum albidum fruits. Ripe wholesome fruits of Chrysophyllum albidum were harvested and treated with different concentrations of CaCl2 (1, 2, and 3%) at three different dip times (5, 10, and 15 min). The goal was to use established analytical methods to investigate the influence of CaCl2 on the firmness, weight loss, pH, titratable acidity, total sugar (TS), pectin, color, microbial (fungi and bacteria) loads of Chrysophyllum albidum fruits. All the treated fruits were stored at ambient temperature 28 ± 2°C and 90± 5% relative humidity for 15 days. The obtained results indicated that treating Chrysophyllum albidum fruits with 3% CaCl2 for 15 min was found the most effective in controlling weight loss, microbial load, color, firmness, and other compositional changes such as pH, titratable acidity, pectin and total sugar. It was observed that CaCl2 treated samples showed reduced fungal loads from 6.00 × 103 SFU/g at harvest to 0.02 × 103 SFU/g after 15 d of storage as compared to untreated samples. No record of bacterial load was detected on Chrysophyllum albidum fruits treated with 3% CaCl2 for 15 min. The shelf life of Chrysophyllum albidum fruits could be extended for 15 d without excessive deterioration in quality by treating the fruits with 3% CaCl2 for 15 min with a minimum quality loss, as compared to the control sample which had greater compositional changes with maximum quality loss during storage at ambient temperature.

Agricultural production is one of the leading sectors in the world and in our country in terms of employment rates. Agricultural production activities, the importance of which is increasing day by day due to the increasing world population, is an important strategic element for every country. The economy of many countries, including our country, still depends on the products they obtain because of agricultural production. Appropriate agricultural policies should be implemented to increase the productivity in agricultural production, to protect the employed workforce and to ensure its continuity. In addition to establishing appropriate agricultural policies, employed workers should also be protected by laws, regulations and directives. It is a fact that most of the people employed in agricultural production in our country must work under dangerous and harsh conditions without being under legal protection, without union formation and union rights, as in other sectors. Protecting the health of agricultural production workers working under very difficult conditions due to variable climatic conditions, ensuring safe production and ensuring that the necessary Occupational Health and Safety measures are taken should be among the priority items when forming our state’s policies. In this study, the situation in the world and in our country was examined under the title of occupational health and safety in agricultural production. The hazards and risk factors to be encountered in agricultural production have been determined and the Occupational Health and Safety measures to be taken against them have been tried to be explained.

Kubilay Kurtulus Bastas
Önümüzdeki yüzyılda küresel iklimin büyük ölçüde değişeceği ve ekosistemlerin bu değişen ortamdan etkileneceği tahmin ediliyor. Bitki ile ilişkili faydalı mikroorganizmalar, bitki büyümesini uyarabilir ve biyotik ve abiyotik streslere karşı direnci artırabilir. Günümüzde artan karbondioksit (CO2), kuraklık ve ısınma gibi iklim değişikliği faktörlerinin bitki faydalı mikroorganizma etkileşimleri üzerindeki etkileri, bitki gelişimi ve sağlığı kapsamında giderek daha fazla araştırılmaktadır. Son çalışmalar, yüksek CO2 seviyesinin mikorizal fungusların bolluğu üzerinde olumlu bir etkiye sahip olduğunu, buna karşın bitki büyümesini teşvik eden bakteriler ve endofitik mantarlar üzerindeki etkilerinin daha değişken olduğunu göstermiştir. Ek olarak, artan CO2 seviyeleri, ısınma ve kuraklığın sonuçları bitkiye ve mikrobiyal genotipe bağlıdır. Ayrıca bitki büyümesini teşvik eden mikroorganizmalar, özellikle bakteriler, kuraklık stresine maruz kalan bitkileri olumlu yönde etkiler. İklim değişikliklerine bağlı olarak değişen faydalı mikroorganizma toplulukları, farklı mikrobiyal topluluklarla rekabet etmek zorunda kalabilir ve bu nedenle mikrobiyal faaliyetler de etkilenebilir. Bu çalışma, iklim değişikliğinin mikroorganizma ve bitki etkileşimlerini etkileyen önemli bir faktör olduğunu, bitkilerde ve mikroorganizmalarda adaptasyon süreçlerinin dikkate alınması gerektiğini ve adapte edilmiş bitki çeşitlerinin seçimini gerektirebileceğini ortaya koymaktadır.

Although snail meat is an important source of protein in terms of human nutrition, it has found a place in the eating and drinking culture of very few communities. Consumption of snail meat is socially accepted in many parts of the Cyprus. It is called as “Garavolli” by the Cypriot people and is also one of the most delicious appetizers. This research is important in determining the consumption behaviour of the people of the Northern Cyprus and determining their preferences depending on cooking methods. According to the results of this study, 32.7% of the participants do not consume snail meat, while 67.3% of them consume snail meat. It is consumed more at home (41.3%), compared to consuming at restaurants (38.1%). While 47% of participants consuming preferred to consume as boiled (with olive oil and vinegar), 3.8% of them preferred to consume as grilled. The most preferred method of cooking is boiling then dipping it to olive oil and vinegar. As we see from the answers, habits directly effect on preference to consume or not to consume the snail meat.

This study was carried out to determine the effects of Bacillus subtilis addition to growing Japanese quail diets on growth performance, some serum parameters and carcass parameters. In the study, a total of 200 mixed-sex Japanese quail (Coturnix coturnix japonica) chicks were fed for 35 days with diets formed with the addition of different levels of control and Bacillus subtilis (250, 500, 750 mg/kg). The study was carried out in 4 treatment groups with 5 replications. At the end of the experiment, Bacillus subtilis levels did not affect the feed intake and feed conversation ratio, which are performance parameters, but affected the body weight and body weight gain statistically significantly. The addition of Bacillus subtilis to the diets of growing Japanese quails showed that glucose and creatinine concentrations were significantly affected, and urea, triglyceride, cholesterol, total protein, phosphorus and calcium values were not affected by the treatment levels. Among the carcass parameters, carcass yield, liver weight, pancreas weight, heart weight, gizzard weight and intestinal length did not statistically differ between the treatment groups. According to the results of the present study, it can be said that the addition of Bacillus subtilis at the level of 500 mg/kg to growing quail diets may be beneficial in terms of improving performance.
