Sous-vide process is a cooking method for vacuumed products which are placed in a water bath or steam oven at controllable low temperatures and specific long times. This technique is widely used for cooking of meat and meat products which have limited shelf life throughout cold storage. Temperature, time and vacuum parameters used in sous-vide method are effective factors on meat quality. It is realised that meat tenderness increases with this technique due to cooking is performed at low temperatures. For the same reason, more water is retained in the texture and cooking losses are reduced. In addition to this, it is appeared that the sous-vide method provides protection of nutrient components that are water-soluble and/or adversely affected by high temperature applications, so that this method increases the nutritional value of meat. On the other hand, use of controllable cooking temperatures facilitates to reach targeted core temperatures in meat. With the help of homogeneous distribution of heat, even colour formation on meat can be observed. Oxidative reactions in the product are limited by the application of vacuum, so that product quality can be preserved for a long time. The risk of food safety as a result of low temperature applications in sous-vide cooking is eliminated by increasing cooking times. In this review, it is aimed to inform about effects of sous-vide cooking technique on meat quality under the heads of; texture, juiciness and cooking losses, colour, flavour, lipid and protein oxidation and microbial quality. Besides, the effects of sous-vide cooking method on quality parameters, different effects of sous-vide and traditional cooking methods on quality parameters were deeply discussed.

In the study, it has been demonstrated its use for a data set obtained from layer hens in a hybrid approach obtained by combining BAGGING and MARS. In the study, the data of 2018 of the egg production enterprise in a private livestock enterprise in the Çukurova Region of Adana province were used. In the research, a data set obtained from Lohman breed chickens, who are at an average age of 60 weeks, was used. Earth (enhanced adaptive regression through hinges) and caret (classification and regression training), mda (Mixture Discriminant Analysis) packages were used in R STUDIO program to provide a stronger solution of regression problems in the created MARS and Bagging MARS algorithm. The estimation performance of the bagging MARS technique was evaluated with the goodness of fit criteria by taking the B value of the bootstrap sample number 3. In the study, the effect of temperature and humidity on egg yield, broken / cracked eggs, number of dead animals and feed consumption was investigated using MARS and bagging MARS analysis. While the effect of evening temperature(t3) on egg yield was found to be significant, it was not included in the estimation equation since morning (t1) and noon(t2) temperatures did not have a significant effect. Since the number of broken / cracked eggs and dead animals is less than 5 weeks, these variables are not included in the estimation equation in MARS and Bagging MARS models. It has been observed that feed consumption has a positive contribution in both models.

Plants are constantly exposed to adverse conditions in their environment, which may occur in different ways, limiting their growth. These negative states that affect and / or prevent growth, development and metabolism in plants are called stress. Salicylic acid (SA) is a hormone-like substance commonly found in plants and is now accepted to play an important role in regulating plant growth and development. Salicylic acid also increases the tolerance of plants under abiotic stress conditions such as salinity, high and low temperature, water, heavy metal, frost and drought stress. This study is one of the important white wine grape varieties belonging to Turkey's Narince grape varieties growing in Tokat made widely used. Salicylic acid (SA) was applied to the plants in 4 different doses (0, 0.5, 1.0, 1.5 µmol l-1) before high temperature stress to be applied and they were exposed to high temperature for 12 hours at 40°C in the growth chamber. At the end of the 21 days after the stress application, shoot length (cm), fresh -dry shoot and root weights (g) were taken in order to follow the plant growth from the plants. Proportional water content (%), Ion flow (%) to reveal the effect of salicylic acid and the cell membrane damage rate (%) was calculated.

Türkiye kuruyemiş üretimi ve tüketimi açısından dünyanın önde gelen ülkeleri arasında yer almakta ve birçok ürün kuruyemiş olarak kullanılmaktadır. Bu ürünlerden biri de karpuz çekirdeğidir. Bu çalışmada Mardin, Diyarbakır ve Batman illerinden temin edilen ve çerezlik olarak tüketilen karpuz çekirdeklerinin bazı kimyasal bileşenleri belirlenmiştir. Ayrıca Batman ilinden temin edilen karpuz çekirdekleri 140, 160 ve 180°C’de 60 dakika boyunca kavrulmuş ve kavurma işleminin karpuz çekirdeği yağının oksidatif stabilitesi üzerine etkileri araştırılmıştır. Karpuz çekirdeklerinin kuru madde, kül, yağ, protein, toplam tokoferol ve toplam fenolik madde miktarlarının sırasıyla %95,39-95,58, %3,10-3,38, %51,65-52,75, %32,76-34,87, 360,12-393,16 mg/kg ve 427,75-478,80 mg GAE/kg yağsız kısım aralıklarında değiştiği tespit edilmiştir. Karpuz tohumlarının yağ asidi bileşimi incelendiğinde ise elzem yağ asidi olan linoleik asit açısından (%60,74) önemli bir kaynak olduğu ve oleik asidi de (%20,48) yüksek miktarda içerdiği belirlenmiştir. Yapılan çalışmada karpuz çekirdeklerinin yağ asidi bileşiminin kavurma işleminden etkilenmediği ve peroksit sayısının ise 1,57- 3,0 meq O2/kg yağ olarak dar bir aralıkta değiştiği gözlenmiştir. Buna karşın kavurma sıcaklığının, örneklerin peroksit değeri üzerindeki etkisi istatistik açıdan önemli bulunmuştur. K232 değerleri örneklerde kavurma süresince 2,54 ile 4,01 arasında değişirken, K268 değerleri ise 4,99 ile 5,04 arasında değişmiştir. 180°C’de kavrulmuş örneklerin K232 ve K268 değerleri 140 ve 160°C’de kavrulmuş olanlardan istatistiksel olarak farklı bulunmuştur. Çalışma sonucunda karpuz çekirdeklerinin elzem yağ asidi olan linoleik asidi önemli miktarlarda içerdiği ve kavurma işleminin yağ oksidasyon parametrelerinde düşük düzeylerde değişimlere neden olduğu tespit edilmiştir.

Edible grapevine leaves can be consumed as fresh or pickled. After leaves are usually collected from vineyards, they are sold as fresh or brined. In Turkey, the leaves of Sultani Çekirdeksiz and Narince varieties are extremely evaluated for edible purposes. In this study, it was aimed to determine leaf yield and characteristics of vine saplings in nursery parcel. The leaves of Narince (Narince own-roted grafted on 1103 P) and Sultani Çekirdeksiz (grafted on 1103 P) seedlings were the material of the experiment. Cuttings were planted in a single row (16.666 cuttings/da) with 1 m × 6 cm spacing to the nursery parcel. Edible leaves were collected from saplings in two harvest periods. Leaf yield, leaf width, leaf length, leaf area and leaf weight in fresh vine leaves were determined. Depending on the sapling type (own-rooted or grafted), 102.5-186.0 kg/da edible leaves were collected from two harvests. In general, saplings leaves were found to be smaller in size and delicate than matura vine. It is recommended that the leaves of saplings should be evaluated by vine sapling companies having permanent workers.

Use of sewage sludge in agriculture is an alternative disposal technique for this waste. Accordingly, the effects of using the sludge obtained from Sivas Waste Water Treatment Plant in different doses (0%, 1%, 2%, 3%, 4%, 5% (w/w) and chemical fertilization) on the yield and nutrient concentration of tomato plants were investigated. The study was carried out with three replications according to the experimental pattern of randomized plots in the plastic pots with the capacity of 3 kg under the greenhouse conditions of Plant and Animal Production Department of Sivas Cumhuriyet University. It has been determined that the weight of the plants roots, stems and green components dry matter increases due to the increasing sewage sludge application and the highest efficiency is in the sewage sludge application of 5%. In addition, it has been determined that the concentrations of nitrogen (N), phosphorus (P) and potassium (K) which are among the macro nutrients, tend to increase depending on the increasing dose of the sewage sludge. The concentrations of copper (Cu), manganese (Mn), iron (Fe), and zinc (Zn) which are among the micro nutrients, increased with the increasing amount of sludge. In this context, it is thought that the sludge can be used in plant breeding, provided that it falls within the boundaries of the legal legislation.

This study was conducted to identify the current problems of cereal crops like wheat and corn producers and to suggest solutions for overcoming those problems in Amik Plain (Antakya, Kirikhan, Kumlu, Reyhanli districts) in Hatay province of Turkey. In this study, the primary data was obtained by face-to-face survey from 100 cereal producers in Amik plain. All variables are given as frequency and percentage distribution, and numerical variables as mean. The survey assessed the level of education of grain producers, the number of individuals in the farm, record keeping, social security, crops (wheat and corn) growing area, yield, sowing and harvest date ranges, property and leasehold land use, cultural practices and grain production. The data were analysed using simple statistical analysis methods (frequency, averages, percentage distribution). The results indicated that about 50% of the cereal producers had higher educational degree. It was determined that producers had an average of 12.3 ha of wheat and 15 ha of corn cultivated area. Moreover, cereal production is well known as one of the cultural practices in the study area. The main problem of grain producers is that the low cereal prices. In addition, the Turkish Grain Board (TMO) does not purchase the production at the time of harvesting. Moreover, high production costs and corn irrigation are considered other problems that cereal producers are facing.

Although the milk’s predominant microflora consists of lactic acid bacteria, it is probable that pathogenic bacteria such as Listeria, Brucella, Mycobacterium, Staphylococcus, Escherichia coli O157: H7 and Salmonella are also present. Due to the fact that milk contains components with high nutritional value and therefore suitable for the growth of microorganisms, the microorganism populations in the milk can reach to the numbers that can threat human health in a short time. Therefore, it is very important to ensure the microbial safety of the milk before it is consumed. Microfiltration, one of the techniques that can be used for this purpose, physically separates the microorganisms from the milk by passing the milk through the membranes having pores with certain diameters by the effect of pressure. Studies on the microorganism load of milk that microfiltration is used showed that the number of microorganisms in milk generally decreases depending on the working conditions such as pore diameters of the membranes, the initial microorganism load of milk, temperature and pressure. The membranes used in microfiltration technique are chosen according to the purpose. It is known that membranes with a pore diameter of 1,4 µm cause a pasteurization effect and membranes with a pore diameter of 0,2 µm cause a sterilization effect. Therefore, the choice of suitable membrane is very important for microfiltration application. Several studies have been done on the effect of microfiltration on extension of shelf life in drinking milk, the removal of bacterial spores which can withstand high temperatures and can cause milk deterioration of milk, the production of dairy products like cheese without damaging the natural components of milk. These researches are important in terms of providing information on a technique that allows the removal of pathogen microorganisms which cause a risk for public health and can cause food poisoning in case of consumption of raw milk and raw milk cheeses, without any change in the natural structure of milk.

The electronic tongue is defined as the device, consisting of a series of sensors, used to characterize the taste of complex liquid or converted into liquid form samples. This device can be used in many fields of application; in medicine, chemistry, environment, and food industry. In the food industry. usually, the electronic tongue is used to control the freshness, the maturity, and the non-deterioration of fruits, vegetables, meats, beverages, and dairy products. Commonly, trained panelists participate in taste and sensory analysis. However, the electronic tongue is preferred due to the encountered disadvantages, where the taste perception is subjective and moreover, varies from an individual to another. In the present review, the basic structure of electronic tongues with different systems, working principles, food application areas, advantages, and disadvantages are discussed.

Backyard chicken farming is as an effective tool for poverty reduction in rural areas, by providing living to resource poor communities; it is an important source of extra cash income other than eggs and meat for family consumption. The present study was carried out to assess the role of backyard poultry farming in supplementing household economy of rural farmers dwelling in district Quetta, Pakistan. Information from ninety-nine randomly selected female backyard poultry farmers were gathered during November 2016 to March 2017. Owing to previous government and non-government interventions backyard poultry keeping was found as an established practice. Women were found the main custodian of backyard poultry birds and consequently were the main beneficiary of the activity. Poultry birds of Fayoumi and Golden / Rhode Island Red (RIR) breeds were the main types. Majority of the farmers reared these birds under scavenging conditions in combination with feeding on household left over dry bread (52%); most of the respondents (62%) were taking care of the birds by themselves which resulted in overall low production cost. Income included the earning received from sale of birds, eggs and the home consumption of poultry meat and eggs. Net income per annum per household was estimated as Pakistani Rupee (PKR) 79290/- (US$ 566). The estimated Rank Based Quotients (R.B.Q) based on farmers perception disclosed backyard poultry keeping as an important domestic source of meat and eggs with almost no or very little capital investment, ranked (I, 80%) followed by a substantial source of supplementary income and was ranked (II, 79%). Amongst the problems, disease outbreaks were the most prevailing problem (I, 90%) followed by unavailability of vaccines (II, 85%). The backyard poultry farming generated subsistence income and provided high quality valuable food that improved household nutrition.
