Tatar, Sule; Okuduci, Ebru
In this study, the accumulation of some heavy metals in water, sediment, and Typha latifolia plant species was investigated in a previously operated mining area located in the Hozat region of Tunceli. In the first phase of the study, water and soil samples were collected from sites where T. latifolia was dominant. The metal uptake capacities from soil to roots, stems, and leaves of the plants were examined for different metals as silver (Ag), barium (Ba), cadmium (Cd), copper (Cu), nickel (Ni), lead (Pb), strontium (Sr), zinc (Zn). Water, sediment, and plant samples collected from the field were analyzed for the above elements at ultra-low detection limits using ICP-MS at ACME Analytical Laboratories in Canada. Bioconcentration factors (BCF-R, BCF-S, BCF-L, respectively) for the root, stem, leaf, and translocation factor (TF) values were calculated. The highest TF value was found to be 0.85 for Sr. The highest bioconcentration factors in the root, stem, and leaves of the plant were also found to be 3.67, 1.55, and 1.79 for Sr, respectively. According to the results obtained, T. latifolia was found to be a suitable plant for the bioaccumulation of Cd, Pb, Cu, and Sr under the existing environmental conditions, but not a suitable bioaccumulator for Ag, Ba, Ni, and Zn. Based on the results, it was determined that some heavy metal pollutants can be remediated using certain plants, and that these plants can function as bioaccumulators for these metals.

The role of natural antioxidants is increasingly important in reducing the damaging effects of free radicals formed in daily life and due to various factors in our en-vironment. In this respect, hawthorn and rosehip fruits, which have high amounts of antioxidants and phenolic substances, attract attention. In this study, some phys-icochemical properties, antioxidant activities, total phenolic substance amounts (TFMM) and phenolic compound compositions of rosehip (Rosa canina) and hawthorn (Crataegus orientalis) fruits growing naturally in Tunceli province were investigated. TFMM was determined as 1265.02-1344.68 in rosehip fruits grown in Tunceli and 318.18-370.85 mg GAE kg-1 fresh weight in hawthorn fruits, antiox-idant activity was determined as 4.83-5.26 in rosehip fruits and 1.85-2.36 μmol AAE g-1 fresh weight in hawthorn fruits. A statistical difference was determined between rosehip and hawthorn wild fruits in terms of antioxidant activity and TFMM, and it was observed that rosehip fruit had higher values than hawthorn fruit in terms of both parameters. It was determined that hawthorn fruit contained higher amounts of epigallocatechin, protocatechuic acid and quercetin-3-glucoside phenolic compounds than rosehip fruit and the difference between the two fruit contents was statistically significant.

Yazdıç, Ferit Can; Açar, Mıkaıl; Cakilcioglu, Ugur; Tasar, Neslihan; Çelik, İbrahim Seyfettin
Centaurea L. is a genus that is systematically discussed and whose taxonomic issues need to be clarified in the light of molecular techniques developed in recent years. This study aims to contribute taxonomically in molecular terms by studying the morphological and phylogenetic relationships of Centaurea bingoelensis. This limited, endemic species grows naturally in the Bingöl province of Türkiye. A phylogenetic analysis based on the molecular marker ITS, which is the most preferred in evolutionary studies and found in nuclear DNA, has been proposed as a molecular marker of C. bingoelensis , an endemic plant in Türkiye, and has not yet been molecularly identified. For this purpose, PCR amplification of the fragment mentioned above was performed, followed by direct sequencing, analysis of nucleotide variation, and phylogenetic analysis with different species. The Centaurea species identified so far have been shown to have three main distinct major clades and the specific phylogenetic methods used (NJ, ML, MP) and the ITS nucleotide sequences analyzed revealed a close phylogenetic relationship between C. bingoelensis and C. spectabilis. For a more accurate phylogenetic classification of this species within the Asteraceae family, their close relationships were probed using similar sequences from the GenBank Database. Phylogenetic analysis of C. bingoelensis specimens using ITS sequences reveals their position in the Asteraceae family and molecular support for these specimens being new species as proposed. Although morphologically similar to C. fenzlii and C. obtusifolia, the remarkable point of our study is that C. bingoelensis is phylogenetically closer to C. spectabilis. This work has exciting implications for understanding the evolution and diversification of the genus Centaurea. In addition, the results of this study show that the samples identified as Centaurea species in Türkiye are still not entirely determined genetically.

İncele - MakaleAçık Erişim2024Evaluation of Novel Plant-Based Milk Produced from Melon Kernel
Aydın, Çağlar Mert
In this study, the possible use of melon kernel (Cucumis melo L.) as a source for production of daily milk alternative was evaluated. For this purpose, the study evaluated proximate composition, physicochemical properties and sensory properties of the milk from Kultik kernel. Overall, proximate composition consists of 88.84% moisture, 1.08 ash, 0.96 protein and 5.50% fat and 3.63% carbohydrate content. Low protein content of the milk limits its usage as an ingredient in the production of fermented dairy products. Physicochemical properties showed that Kultik kernel milk is rich in nutritional value. Rheological behaviour of the milk showed non-Newtonian with pseudoplastic character. Similar flow character to dairy milk enables the milk sample to be produced in existing equipment and processes, allowing large-scale industrial production. In addition, sensory scores of the milk sample were low, thus new formulas including the milk samples should be developed in further studies.

Evaporasyon işlemi sıvı gıda ürünü içerisinde bulunan suyun fiziksel olarak uzaklaştırılmasıdır. Bu işlemde geleneksel ısıtma teknikleri sonucunda istenmeyen bileşen oluşumu, kalite kaybı ve aroma kayıpları meydana gelmektedir. Bu nedenle gelişen teknoloji ile geleneksel gıda işlemi uygulamalarının yerini alternatif teknikler almaktadır. Bu tekniklerin başında ohmik ısıtma işlemi gelmektedir. Ohmik ısıtma işlemi iki elektrot arasında alternatif akım geçirilerek ürünün ısınma prensibine dayanmaktadır. Bu çalışmanın ana amacı üç farklı voltaj gradyanı kullanılarak elde edilen dut pekmezinin renk değerlerinin incelenmesidir. Örnekler ohmik evaporasyon işlemi ile üç farklı voltaj gradyanında atmosferik koşullar altında %22,2 Suda Çözünür Kuru Madde (SÇKM) içeriğinden %68 SÇKM değerine kadar evaporasyon işlemine tabi tutulmuştur. Örneklere ait L*, a*, ve b* renk değerleri ölçülmüştür. Elde edilen L*, a*, ve b* değerlerinden beyazlık ve kahverengileşme gibi bazı renk indeksleri hesaplanmıştır. Beyazlık indeksi (Bİ) ve kahverengileşme indeksi (Kİ) incelendiğinde, en yüksek değerler geleneksel yöntemde elde edilirken en düşük değerler 15 V/cm voltaj gradyanında elde edilmiştir. Toplam renk değişim değerinin 3,73-8,97 arasında değiştiği, en düşük renk değişim değerinin geleneksel yöntemle elde edildiği ve bu değerin yükselen voltaj gradyanı ile arttığı belirlenmiştir. Sonuç olarak, dut pekmezi örnekleri renk değişimleri açısından incelendiğinde genel anlamda voltaj gradyanın artmasından olumsuz etkilendiği tespit edilmiştir. Bununla birlikte fiziksel kalite değerlerinin başında yer alan renk değerleri bakımından nispeten daha düşük voltajlı ohmik evaporasyon işleminin kullanılabileceği düşünülmektedir.
