Monica Oluwatoyin Oguntimehin | Adebanjo Ayobamidele Badejo | Victor Ndigwe Enujiugha
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.

Phloxine is used as a food dye. In this study, genotoxicity of phloxine at the root tip of Allium cepa L. was investigated. A. cepa L. meristematic root tip cells were treated with ten different doses of phloxine. In this way, the EC50 value was determined. Then, phloxine was applied to root tips at EC50/2, EC50 and EC50×2 doses. Treatment time was determined as 24, 48 and 72 hours. As a result, it was revealed that phloxine caused chromosomal aberrations in cells in mitotic cycle at the root tip of A. cepa. There are equatorial plate shifting in metaphase, laggard chromosome, disturbed spindle, chromosome stickiness, C-mitosis, polar shifting among the observed chromosomal aberrations. It was stated that the % chromosomal aberration index (CAI) increased depending on concentration increase. It has been demonstrated that the highest % chromosomal aberration index occurred at the EC50×2 dose for 72 hours. According to the research, it was revealed that phloxine has a genotoxic effect on the root cells of A. cepa. For this reason, it can be emphasized that care should be taken in its use in foods.

Muzaffer Barut | Leyla Sezen Tansı | Sengul Karaman
demand for its essential oil continues to grow on a global scale. The fact remains that harvesting at the right time of growth is critical to maximizing the rate of active ingredients found in the plant. Thus, in the current study, L. angustifolia plants were collected at various growth stages (pre-flowering, mid-flowering, and post-flowering) from Adana, Turkey in order to determine the most suitable harvest time for the highest amount of essential oils and its important compounds. The highest flower essential oil content (7.50 mL 100 g-1) was obtained at mid-flowering of the third year of plantation. The major compounds for L. angustifolia were linalyl acetate (25.63-31.63%), linalool (16.33-24.79%), nerol (8.83-13.43%), beta-farnesene (3.67-5.70%), β-cis-ocimene (1.76-8.14%), respectively. The obtained data have been inquired by principal components analysis (PCA), allowing differentiation of plantation ages and growth stages. Compared to the plantation ages, essential oil content and linalool content increased significantly in the third year of cultivation. As a result, the most suitable harvest time may be considered as mid-flowering in terms of essential oil content and in terms of high linalyl acetate and linalool content.
