Carotenoids which are a lipophilic component are an organic pigment with antioxidant properties that contain conjugated double bonds. Research on carotenoids have recently concentrated on functional foods, bioavailability and pharmacology due to their potential health benefits to humans. Carotenoid components are occurred a reduction of the biological activity by effect of undesired environmental conditions such as oxygen, heat, light, humidity during food processing and storage or gastrointestinal tract. Applicability in aqueous systems of carotenoids is limited because of lipophilic. Therefore, microencapsulation is an effective way to overcome these problems. Various microencapsulation technique such as spray drying, freeze drying, extrusion, conservation and emulsification has been developed. Besides selected microencapsulation method, coating material is also important in the encapsulation. Recently, multi-layers emulsification method is attracted interest in improving stability, availability in aqueous system and bioavailability of carotenoid load microcapsules. İt is stated in studies that developed microencapsulation techniques or using combine microencapsulation techniques increase encapsulation efficiency and yield. In the present paper, it is aimed to present using microencapsulation techniques in order to enhance stability and bioavailability of carotenoids which are a sensitive component, and current research, developments and trends about the subject.

Peynir üretimi ile eski zamanlardan bu yana önemli bir yere sahip olan Kırklareli ilinde önemli ticari potansiyele sahip olan iki farklı peynir, Kırklareli Beyaz Peyniri (KBP) ve KBP ve KEKP üretiminde belli oranlarda koyun sütü, keçi sütü ve inek sütü karışımı kullanılmaktadır. Kırklareli peynirlerini ayırt edici kılan temel bazı özellikler mevcuttur. Bu özellikleri coğrafi yapı ve iklim koşullarına bağlı olarak ortaya çıkan doğal bitki örtüsünün getirdiği etki, peynir hammaddesi olan sütün taşımış olduğu farklılıklar, son olarak ve en önemlisi ise üretim yöntemi ve olgunlaşma sürecinde yer alan temel farklılıklar ile belirtildiği gibi süregelen tarihsel ustalık şeklinde özetlemek mümkündür. KBP ve KEKP taşıdığı farklılıkları bir zincir gibi hayvan beslenmesinden, süte, sütten peynire yansımaktadır. İlin botanik kompozisyonunu oluşturan türlerin oranları hayvanların yemini oluşturmaktadır. Botanik özelliklerine göre Kırklareli meralarında yaygın olan bitkiler buğdaygiller (Poaceae), baklagiller (Fabaceae), geniş yapraklı otlar (Asteraceae, Apiaceae, Lamiaceae vd.) ve çalılardır (Fagaceae vd.). Bu 3 farklı bitki grubunun süt ve peynir üzerine farklı şekillerde etkileri bulunmaktadır ve protein miktarı, yağ oranı vb. gibi en temel kalite kriterlerini etkilemektedir. Bunların dışında sütün mikrobiyal yükünün çok düşük olması ile başlayan ve üretim koşullarının getirdiği birçok farklılık ta mevcuttur. İlde üretilen sütlerin AB kriterlerine uygun olması, öncelikle düşük pastörizasyon sıcaklığı gibi çok önemli bir avantajı beraberinde getirmektedir. Üretimlerinde yalnızca inek sütü kullanılabileceği gibi koyun sütü, keçi sütü ve inek sütü karışımı da kullanılabilir. Karışım oranları ise %30-%45 koyun sütü, %25-%40 keçi sütü, %15-%30 inek sütü şeklindedir.

Pesticides have both acute and chronic effects on humans and all other warm blooded living things. In pesticide applications, few of the amount used reaches the target organisms, whereas the rest mixes into the ecosystem and leads to the deterioration of the ongoing natural balance. Therefore, growing attention has been given toward the development of alternate environmentally friendly pesticides/insecticides that would aid an efficient pest management system and also prevent chronic exposures leading to diseases. In this context, plant-derived natural products are considered valuable candidates to reverse this negative trend. Botanical pesticides are relatively safe, degradable, and are readily available sources of biopesticides. Neem is an ideal alternative candidate as a natural non-synthetic plant pesticide. The neem products have been obtained from several species of neem trees in the family Meliaceae. Array of more than 300 bioactive compounds in the neem tree makes it a unique plant with potential applications in pest and vector management. Botanical pesticides, such as neem, have limited persistence in the environment, and ultraviolet light, temperature, rainfall and other environmental factors can degrade neem. Unlike toxic synthetic insecticides, neem materials do not kill the pest, but incapacitate or neutralize it via cumulative behavioural, physiological, and cytological effects. In spite of high selectivity, neem materials affect more than 400 harmful species including insect pests, phytophagous mites, mites, and ticks affecting man and animals, parasitic protozoans, noxious molluscs, plant parasitic nematodes, pathogenic fungi, and harmful bacteria and fungi. Neem ingredients affect insects in various ways such as repellent, antifeedant, toxic, fecundity and growth regulatory effects. This review presents an overview of recent advances in research on the environmental impact of neem products and their use and effectiveness as a biopesticide.

According to World Health Organization (WHO), an estimated 600 million people fall ill after eating contaminated food and 420 000 die every year. Although various foods can serve as sources of foodborne illness, meat has been at the forefront of societal concerns in recent years. Meat is source of some foodborne pathogens which have an important role on human health. In this study, it was aimed to examine the microbiological quality of raw bovine meat samples sold in Tokat province and to evaluate the results in the context of food safety. For this purpose, 18 raw meat samples purchased from butchers and markets were analyzed for total mesophilic aerobic bacteria, total psychrophilic aerobic bacteria, yeasts-molds, lactic acid bacteria, B. cereus, S. aureus, C. perfringens, total coliform, and fecal coliform. The presence of E. coli, E. coli O157:H7, L. monocytogenes and Salmonella spp. were also investigated in these samples. The lowest and highest values determined for the parameters were as follows: total mesophilic aerobic bacteria 1.46×104-1.26×107 CFU/g, total psychrotrofic aerobic bacteria 1.01×104-2.65×106 CFU/g, yeasts-molds 3.00×103-1.70×104 CFU/g, lactic acid bacteria 2.70×103-3.60×104 CFU/g, B. cereus ˂102-7.20×104 CFU/g, S. aureus 2.60×103-2.57×105 CFU/g, C. perfringens ˂102-9.20×103 CFU/g, total coliform 3.80×101-2.90×104 MPN/g, and fecal coliform

Two different thyme species (Thymus vulgaris L. and Origanum majorana L.), sage (Salvia officinalis L.) and lavender (Lavandula officinalis L.) extracts were tested against pre-adult stage of Potato tuber moth-PTM [(Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae)], which is an important quarantine pest. Each plant extracts prepared with ethanol were applied to larvae and eggs in three different concentrations 3%, 5 and 10 ml/L. In the egg treatments at the highest concentration (10% ml/L), inhibition rate was observed in Lavander and T. vulgaris 73.7%, in O. majorana 67.5% and in sage 66.2%, respectively. Results indicated that the mean number of hatching eggs were highly decreased as concentration increased, the highest decreased was observed with treated 10% concentration. of lavender and T. vulgaris. Observation were for 7 days. In the insecticidal toxicity study of against the larval stage, mortality were determined at the highest concentration (10% ml/L) in O. majorana 91.2%, Lavander 90%, T. vulgaris 87%, and Sage 83.7% at the end of 7th day. It was also determined that the larval mortality rate was higher with the increasing of extracts of 4 different plant depending on time. As a result, in this study, ovicidal toxicity of plant extracts was recorded against to on egg stage and it was that impact of insecticidal against to on larval stage also.

Gümüşhacıköy Basma is famous for its aromatic structure in oriental type tobacco. However, it is known that new types of oriental tobacco have become widespread by adding Taşova, Erbaa and Niksar lines to the production area of this type of tobacco, especially due to the decrease in production since the beginning of 2000s. In this study, yield and quality performances of some oriental tobacco parents and hybrids in Gümüşhacıköy ecological conditions and heterosis and heterobeltiosis values of these hybrids were emphasized. Hybrid lines were obtained in 2016 by half-diallel hybridization from Xanthi-2A, Erbaa, Nail, Katerini and Canik 10821 (Sıtmasuyu) genotypes. The study was carried out with 5 parents and 4 F1 populations with their hybrids. Yield and yield related characteristics (plant height, number of leaves, leaf width and height), as well as glucose, fructose, nicotine, chlorogenic acid and routine contents were examined. It was determined that genotypes showed significant differences in all traits except leaf length. Hybrids outperformed their parents in all parameters except plant height and number of leaves. This advantage was 8.42% in yield, 7.73% in quality, 8.64% in reducing sugar, 3.49% in nicotine and 15.20% in chlorogenic acid + routine. The effect of leaf width on yield and chlorogenic acid + routine content on quality were determined. As a result of the study, when heterosis and heterobeltiosis data were evaluated, it was found that Xanthi 2A x Katerini hybrid showed promising results.

In this research, biogenic amine types and quantity of Tulum and Kashar cheeses were determined. In addition, the relationship between biogenic amines and some microbiological-chemical properties of cheese samples were investigated. The contents of tryptamine, phenylethylamine, putrecine, cadaverine, histamine, tyramine of totally 40 samples (20 of each cheese) were examined. While only one sample of Tulum cheeses had no biogenic amines, different levels of biogenic amines were determined in other samples. No significant relation was confirmed between the biogenic amine quantity and total aerobic mesophilic bacteria, lactic acid bacteria, enterococci bacteria count, but there was a correlation between some biogenic amine contents and chemical properties which are tyrosine, lactic acid, pH, protein and ripening coefficient. Biogenic amine levels determined in the cheeses found below hazard limit values according to what legal limit.

Ganoderma lucidum (Curtis) P. Karst., known as “Lingzhi” in China or “Reishi” in Japan, is a well-known medicinal mushroom and traditional Chinese medicine, which has been used for the prevention and treatment of bronchitis, allergies, hepatitis, immunological disorders and cancer. G. lucidum is rarely collected from nature and mostly cultivated on wood logs and sawdust in plastic bags or bottles to meet the demands of international markets. Diverse groups of chemical compounds with pharmacological activities, isolated from the mycelia and fruiting bodies of G. lucidum are triterpenoids, polysaccharides (β-D-glucans), proteins, amino acids, nucleosides, alkaloids, steroids, lactones, lectins, fatty acids, and enzymes. The biologically active compounds as primarily triterpenoids and polysaccharides of G. lucidum have been reported to possess hepatoprotective, antihypertensive, hypocholesterolemic, antihistaminic effects and antioxidant, antitumor, immunomodulatory, and antiangiogenic activities. Several formulations have been developed, patented and used as nutraceuticals, nutriceuticals and pharmaceuticals from G. lucidum’s water or ethanol extracts and rarely purified active compounds. As the result of clinical trials, various products have commercially become available as syrup, injection, tablet, tincture or bolus of powdered medicine and an ingredient or additive in dark chocolate bars and organic fermented medicinal mushroom drink mixes such as green teas, coffees, and hot cacaos. This review has intended to give and discuss recent knowledge on phytochemical and pharmacological compositions, therapeutic and side effects, clinical trials, and commercial products of G. lucidum.

The aim of this study was to determine students' consumption behavior based on their awareness of food safety. Data were collected using survey method. Study sample consisted of 400 students of Ünye Faculty of Economics and Administrative Sciences, Ordu University, Turkey. Chi-square test was used to determine whether participants’ levels of awareness of food safety differed by socio-economic characteristics. One-way analysis of variance (ANOVA) was used to determine differences in mean scores among awareness groups (low, medium and high) in terms of reading the nutrition information on food labels, food purchasing venues to be reliable and factors affecting food purchase decisions. Results showed that expiry date was the most important factor in food purchase decisions, followed by dates of production and packaging. Participants’ levels of awareness of food safety significantly differed by the proportion of monthly income allocated to food and their preference for cheap foods containing GMO. Supermarkets were ranked the most reliable venues for safe food purchasing, followed by groceries and greengrocers. Results also showed that food purchase decisions of the low and medium awareness groups were mostly affected by their families while those of the high awareness group were mostly affected by their doctors. Results indicate that firstly parents' awareness should be raised about food safety and safe food consumption so that future generations can be more conscious of these issues. In addition, courses on these matters should be included in curricula, and seminars or workshops should be held to raise students' awareness of food safety.

Bu çalışma, Sinop ili Erfelek ilçesinde bulunan Gümüşsuyu Göleti’nin su kalitesi ve kirliliğini belirlemek amacıyla yapılmıştır. Bu amaçla, su kalitesini belirlemede kullanılan fiziksel ve kimyasal su parametreleri, Nisan 2018 – Mart 2019 tarihleri arasında aylık olarak alınan su örneklerinden ölçülmüştür. Bu ölçümler, Gümüşsuyu Göleti’nin bütününü temsil eden dört istasyon için yapılmıştır. İstasyonlar, Gümüşsuyu Göleti’nin doğusu, kuzeybatısı (en derin yeri), güneyi ve batısı olarak seçilmiştir. Çalışma süresince, belirlenen bu dört istasyondan ayda bir su numuneleri alınmış ve elde edilen on iki aylık ortalama değerler (genel ortalama, standart sapma, mevsimsel ortalama) incelenmiştir. Bu dört istasyondan alınan su örneklerinde su kalitesini belirlemek amacıyla çözünmüş oksijen (mg/L), pH, sıcaklık (oC), tuzluluk (ppt), demir (µg/L), kurşun (µg/L), bakır (µg/L), kadmiyum (µg/L), civa (µg/L), nikel (µg/L), ve çinko (µg/L) parametrelerinin analizleri yapılmıştır. Çalışmada, ölçülen su kalitesi parametrelerinin yıllık ortalama değerlerinin istatistiksel verileri mevsimsel olarak da karşılaştırılmıştır. Sonuç olarak Gümüşsuyu Göleti’nin, Yüzey Suları Su Kalitesi Yönetim Yönetmeliği’ne göre II. sınıf su kalitesine sahip olduğu tespit edilmiştir. Ayrıca, gölette herhangi bir kirlilik problemi olmadığı belirlenmiştir. Ancak, gölet suyu çok sert sular sınıfına girmekle birlikte, yetiştiricilik açısından bu durumun bir sakıncası bulunmamaktadır. Tüm sonuçlar değerlendirildiğinde göletin, alabalık gibi soğuk su türlerinin yetiştiriciliği için uygun olabileceği önerilmektedir.
