2020
Muhammad Fakhar-e-Alam Kulyar | Zeeshan Ahmad Bhutta | Moazam Ali | Shah Nawaz | Muhammad Asif
Traditional medicine is still the only treatment in many rural areas especially the rural communities of east. Due to limited access to modern medicine, local people use medicinal plants to treat most diseases. Some herbs contain powerful contents and must be treated with the same precautionary care as in the case of drug, we do. In fact, a lot of drugs are basically based on artificial verities of natural composite in plants. For example, the heart drug Digitalis comes from a foxglove plant. Some drugs are single active substance derived from botanical sources. Herbalists believe that if the active ingredient is isolated from other parts of the plant, its action may be lost or its safety may be reduced. E.g, salicylic acid is present in a plant of meadowsweet which is used for aspirin production. Aspirin may cause bleeding in the gastric mucosa, but meadowsweet contains some other compounds naturally that interfere with the stimulation of salicylic acid. According to some practitioners, the effect of whole plant is greater than its parts individually. Critics believe that the nature of the herbs makes itself difficult to administer of such active ingredients. Herbs contain active ingredients, Mostly of them have unknown ingredients. As with other prescription drugs, herbs should always be prescribed by a qualified doctor.

Mustafa Bayram | Semra Topuz | Cemal Kaya
Olive leaves which is one of the by-products of olive tree cultivation and olive processing industry, have been used in traditional folk medicine for centuries. In recent studies, it has been determined that olive leaf has many bioactivities and these effects have been associated with high phenolic compound content. The most dominant phenolic compound of olive leaf is oleuropein, which is the heterosidic ester of elenolic acid and 3,4-dihydroxyphenylethanol. Therefore, some studies have been carried out for extracting high value added compounds from olive leaves in recent years. Antioxidant and antimicrobial activities of crude phenolic extract and oleuropein have been investigated. Moreover, some studies have been carried out to increase the possibility of using olive leaf extract and oleuropein in food industry due to increasing suspicion of side effects and toxicity of synthetic food preservatives. In this review, it was aimed to investigate phenolic compounds of olive leaf extract, phenolic compound extraction from olive leaf as well as antioxidant, antimicrobial activity of olive leaf extract and oleuropein and possibilities of use in foods.

Anthocyanins, a major natural food colorant rich in mango powder, need considerable protection during processing and storage for better retention due to colour instability. The purpose of the study is to evaluate the stability of the anthocyanin’s extracts obtained from cabinet dried mango powder under different factors which could disrupted the anthocyanin pigments during processing. The factors are processing temperature and time (30°C, 60°C and 80°C for 10, 20 and 30 minutes each, respectively), storage conditions (room temperature, refrigerator temperature and freezing temperature), pH (2, 3, 4, 7 and 10), oxygen, influence of light, different extraction solvent (methanol, absolute ethanol, acidified ethanol (1%), and 50% KMS -Ethanol), sugar level (20%, 40%, and 60%). The intensity of the extracted colour was measured at wavelength 520 nm using UV-VIS spectrophotometer. The results can elucidate the increasing heating temperature and time, sugar content, and exposure to light is able to spoil the anthocyanin molecule. There was a proportional effect of pH and oxygen. The anthocyanin stability was found better in pH=10, acidified ethanol (1%) as extracting solvents, absence of light as processing condition and refrigeration temperature as storage temperature. Hence, these findings could be useful in the food industry to choose a proper processing condition for development of mango powders-based products for satisfying the consumer perception by retaining anthocyanin pigment.

Büşra Ulu | Bahar Bayhan
The species of the Congridae family belonging to the Anguilliformes order are known as conger eel, and are morphologically similar to the eels which are among the species of the Anguillidae family. In both family species, the dorsal and anal fins are combined with the caudal fin. It is easily distinguished from eel species by the appearance of dorsal fin rays at a closer level to the head. There are 195 species belonging to 30 genus distributed in the world seas belonging to the Congridae family. A third genus of 3 species [Ariosoma balearicum (Delaroche, 1809), Gnathophis mystax (Delaroche, 1809) and Conger conger (Linnaeus, 1758)] shows the distribution of Turkish seas. While the first two species have distributed only Turkey's Aegean and Mediterranean seas, C. conger shows the distribution of all our seas. In this review, where morphological and biological characteristics of European conger are distributed in our country, all studies carried out both in our country and abroad are examined in detail and presented together. With this compilation study, especially biological information about species is missing in our country and attention has been made to contribute to the literature.

Nazife Yiğit Kayhan | İlkay Çorak Öcal
Akrepler, Arachnida sınıfında yer alan zehirli arthropodlardan olup, bilinen en eski karasal eklembacaklılardır ve yaşayan fosiller olarak da tanımlanmaktadırlar. Akrepler kendilerine özgü bir takım özelliklere, özel yapılara sahip olmaları ve zehirlenme vakalarına sebep olmaları nedeniyle çeşitli araştırmalara konu olmuştur. Ancak, akreplere özgü bir duyu organı olan ve tarak organı olarak da bilinen pektin organın yapısı hakkında çok fazla bilgi bulunmamaktadır. Bu çalışmada, Protoiurus kraepelini (von Ubisch, 1922) akrebinin tarak organ yapısı ışık mikroskobu ve taramalı elektron mikroskop (SEM) kullanarak çalışılmış, detaylı morfolojik ve histolojik özellikleri belirlenmiştir. Örnekler Eğirdir (Isparta, Türkiye)’de yapılan arazi çalışmalarında toplanamıştır. P. kraepelini’nin tarak organı diğer akreplerde olduğu gibi bir çift olarak mesosomal ikinci segmentin ventrolateralinde yerleşmiş olup genel mimariye uygun olarak marjinal lamella, median lamella ve pektinal dişler olmak üzere üç kısımdan oluşmaktadır. Aynı zamanda bu yapılar üzerinde yer alan duyusal kılları, pektinal dişler üzerindeki peg sensillanın morfolojileri incelenmiştir. Bu çalışmada, ilk kez P. kraepelini’nin tarak organının histolojisi ortaya konulmuş ve yapı - fonksiyon arasındaki bağlantı uyarınca olası fonksiyonları tartışılmıştır.

2020
Canan Kuru | İsmail Tontul
The preference for plant-based foods has been increased in recent years. Animal milk alternatives, named as plant-based milk, are produced from different oilseeds, nuts and cereals by a series of processing steps. These plant-based milk have different advantages over animal milk such as being lactose and cholesterol-free and having a high content of phenolics, minerals and unsaturated fatty acids. On the contrary, they generally have a lower content of proteins and low sensorial acceptability. To overcome these disadvantages, an optimisation by mixture design was carried out to produce high-quality plant-based milk in terms of chemical, physical and sensorial properties. The results showed that dry matter (7.7-11.5 g/100 mL) and ash (0.11-0.46 g/100 mL) content of the samples increased using a combination of sunflower seeds and pumpkin seeds. Total phenolic content and DPPH radical scavenging activity of plant-based milk were governed by the ratio of sunflower seeds. Hazelnut ratio in the samples had a positive impact on protein content (0.17-1.85 g/100 mL), whiteness index, serum stability and sensorial properties. The optimum formulation was determined as 66.3% hazelnut, 0% pumpkin seed and 33.7% sunflower seed. Verification studies showed a good agreement between theoretical and experimental responses.

Efficient use of water, one of the most critical life elements in the world, is becoming more and more important day by day. With the continuous increase in population and with climate change problems occur in terms of both consumption rate and usage patterns of water resources. It is becoming increasingly important to apply and research methods that can solve these problems all over the world. One of these solutions is the “Water Harvesting” method, which goes back many years. Water harvesting can be defined as the accumulation of runoff generated by precipitation to provide water for human, animal or crop use. While it is possible to see the use of the technique with roof and farm systems in micro-catchment dimension; wadi-bed and off-wadi (diversion) systems are used in macro-catchment dimension. In agricultural production, which uses a significant part of water resources, most of the rainwater falling into arid and semi-arid regions where production continues, goes away before could using efficiently by evaporation or flow. For this reason, the use of water resources becomes mandatory by using traditional irrigation methods in agricultural lands. With the water harvesting technique, after storing rain water, it can be held to be applied to crops. Hence the method since there will be no losses due to evaporation or flow, it will increase the total amount of irrigation water and reduce the pressure on water resources. Except for the protection of water resources, its role in preventing soil erosion is also seen as one of the main benefits of the method. In general, when the appropriate method is selected according to the appropriate geography, water harvesting has low inputs and is not difficult to apply. With a few exceptions, it does not require the use of pumps or energy input to deliver or deliver harvested water. In this study, information is given about the main elements, different usage areas and techniques of water harvesting.

Muhammed Taşova | İsmail Naneli
With the increase in the population in the world and in our country, the energy requirement related to consumer demands is constantly increasing. In our country, although wind, sun, etc. energy sources are used in energy production, fuels of fossil origin (coal, natural gas, oil etc.) are used more in energy production. Renewable energy sources, which are alternative due to the decrease in fossil fuel reserves, negative environmental effects and inability to meet the energy needs in the future, come to the fore. In this study, Turkey Statistical Institute (TUIK) according to the 2015-2019 year data, Sakarya at the central and districts in cultivation areas for cultivated of using the amounts of maize and wheat product (da) average waste, dry matter, and volatile dry matter, methane and energy their potential has been determined. As a result of the calculations, it has been determined that the maize sap waste amount has the highest 25695.68 tons of waste and 201197.15 MJ energy potential in Adapazarı district in 2017. Among the wheat stalk wastes, in 2017, Geyve district had the highest 269.95 tons of waste and 2113.72 MJ energy respectively.

Gülistan Erdal | Hilmi Erdal | Adnan Çiçek
This paper studied the effect of livestock support policies applied in Turkey by a emprical study. The study was carried out based on the analysis of the data collected through surveys with a total of 478 livestock enterprises in the TR83 region (including Amasya, Çorum, Samsun and Tokat provinces). The enterprises included in the survey study were grouped into three categories by the number of their animals. Binary Logistic Regression Model was applied in order to define the policy-based support payment utilization probabilities of the enterprises and the factors affecting them. It was determined that approximately 45% of the enterprises cannot utilize livestock supports. The most utilized support items by the enterprises were determined as calf support, support per animal, forage plant support and raw milk support. A total of 65% of the enterprise owners think that the support amount per animal is insufficient, but regard the mentioned support item as the most important factor for improving animal presence. The utilization rates vary in terms of enterprise scales on the other hand. The support utilization likelihood of medium-scale enterprises is 3.1 times higher than small-scale enterprises, and this likelihood is 1.7 times higher for big-scale enterprises when compared with medium-scale enterprises. The study recommends that some regulations are needed in support of policies to enable a better improvement in animal presence and a homogenous distribution of support payments.

Emrah Çoban | Hüseyin Karlıdağ | İbrahim Kutalmış Kutsal
This study was carried out between 2017 and 2018 to determine physical and chemical influences of two drying methods (drying on wooden fruit drying trays and drying cloths), two harvesting periods (commercial / physiological maturity and late harvest), and two harvesting methods (harvesting by hand and shaking) on dried fruit samples of Hacıhaliloğlu and Kabaaşı cultivars. Titrable acidity, browning level, total phenolic content, antioxidant activity (ABTS), color (L*, a*, b*), pH, humidity and water activity (aw) parameters of dried fruit samples were examined. Results indicated that different harvesting periods, methods and drying methods significantly affected almost all fruit quality parameters. L value was higher in apricots dried on trays than dried on the cloths. L* values of dried apricots ranged from 27,13 to 54,74. Similarly, moisture content and water activity values were also found to be lower in apricots dried on wooden fruit drying trays than dried on clothes. When chemical parameters were examined, it was observed that phenolic compounds and total antioxidant contents decreased with fruit ripening. The effect of the applications on drying efficiency was not determined as significant, on the contrary, the individual weights of the dried apricots harvested at the late period were found significantly higher and the number of dried apricots per kilogram was lower. As a result of the study, it was concluded that in sun-dried apricot production, harvesting at late period and the drying on trays positively affected various quality parameters.
