Bilinçsiz ve yoğun kullanılan pestisitlerin insan ve çevre sağlığı açısından önemli problemlere yol açtığı pek çok çalışma ile ortaya konulmuştur. Bu anlamda üreticilerin pestisit kullanımındaki bilinç düzeylerinin araştırılması önem arz etmektedir. Araştırmanın ana materyalini; Tokat ili merkez ilçede belirlenmiş olan 10 adet köyde meyve-sebze üretimi ile uğraşan üreticiler ile yapılan anket verileri oluşturmaktadır. Köylerin üretim miktarı göz önüne alınarak toplam 110 anket yapılmıştır. Veriler 2017 yılı Ekim-Aralık ayına aittir. Anketlerden elde edilen bilgilere göre, Tokat’ta meyve-sebze- üreticilerinin %97’sinin pestisit kullandığı ancak yaklaşık %50’sinin kullandıkları ilaç içeriği hakkında bilgisinin olmadığı belirlenmiştir. Üreticilerin pestisit seçiminde kendi tecrübeleri (%50) ve ilaç bayilerinin tavsiyelerini (%80) dikkate aldıkları gözlenmiştir. Üreticilerin yaklaşık %55’i pestisit kullanım maliyetlerinin 2 bin TL ile 5 bin TL arasında değiştiğini belirtmişlerdir. Üreticiler ilaçlama yaparken korunma önlemlerini tam olarak almadıklarını daha çok eldiven ve maske kullandıklarını belirtirken pestisitlerin insan ve çevre sağlığına verdiği zararlar boyutunda bilinçsiz olduklarını kabul etmektedirler. Ancak üreticiler, pestisit kullanımının ürünlerde bıraktığı kalıntı oranlarının gıda güvenliği açısından oluşturduğu tehlike hakkında hiçbir fikre sahip değildirler. Bunun yanında köylerinde ya da ortak bir bölgede yapılacak eğitimlere kayıtsız kalmayacaklarını ifade etmişlerdir. Bu bağlamda üreticilerin bilinçlendirilmesi konusunda uzman eğitimlerin yapılması ve bu eğitimlerin sürekliliğinin sağlanması, kalıntı analizlerinin yapılarak verilen eğitimlerin geri beslemesinin izlenmesi gerekmektedir.

Anoectochilus formosanus Hayata was demonstrated to have a benefit healthy due to containing active pharmaceutical ingredients. However, A. formosanus is usually processed to produce tea bags which would destroy the bioactive compounds because of the processing procedure. The aim of this study was to evaluate the influence of extracted methods including microwave-assisted extraction (MAE), ultrasound-assisted extraction (UAE), and fermentation by Lactobacillus acidophilus ATCC-4356 to extract the active pharmaceutical ingredients from A. formosanus. The extracted liquid was analyzed total phenolics, total polysaccharide, and antioxidant activity. The results showed that three methods have a positive effect on the extraction of bioactive compounds of A. formosanus in which the fermentation showed the best result. The total phenolic content, total polysaccharide content and antioxidant capacity that extracted by the fermentation method were 11.762 mg GAE/g; 48.914 mg GE/g, and 1.582 mgVit C/g compare to MAE and UAE which were 7.818 mg and 8.128 GAE/g samples; 41.22 and 37.91mg GE/g samples; 1.032 and 1.163 mgVit C/g respectively. The A. formosanus fermentation method by L. acidophilus promotes bioactive compounds of high biological value. This study would suggest a novel use of lactic fermenting A. formosanus in the production of functional foods.

Gamma aminobutyric acid (GABA) is known as an important inhibitory neurotransmitter in the human brain. Recent studies have proved the beneficial effects of GABA on human health. It has been reported that in people who use GABA supplements, the factors affecting the life quality negatively such as psychological problems, insomnia and immune problems have decreased. Studies in this field have shown that lactic acid bacteria (LAB) can produce GABA. For this reason, interest in LAB producing GABA is steadily increasing. It is stated that GABA produced by natural LAB has almost no side effects compared to synthetically created ones. It is also suggested that GABA-producing LAB, which is isolated from especially in Far East countries foods, should be used to develop functional foods. More research needs to be done in order to proceed in this newly developing area, and the undiscovered features of GABA need to be investigated. In this review, the importance of GABA is addressed and the studies about GABA are examined.

South-eastern Anatolia has the largest agricultural areas and the countryside living in this region are engaged in agriculture. Loans extended to agriculture by banks are considered to contribute to regional development as a support to the sector. In this paper, the relationship between the GDP of the South-eastern region and the loans extended by the banks to the agricultural sector in this region were investigated in the period of 1988-2017. Lee-Strazicich structural break test and Dolado-Lütkepohl and Bootstrapt causality test was applied to determine the causal relationship between the variables in the analysis. Unlike the others this paper contributes to the literature as it examines the effect of agricultural loans on the development of the region and different tests are used. As a result of the study, the breaking years of the series were determined and interpreted economically. In addition, bi-directional causality relationship between regional growth and agricultural loans was determined. It can be said that agricultural loans contributed to regional development in the South-eastern Anatolia region. It can be presented as a policy proposal that increasing the loans extended to the sector in the region. The effectiveness of agricultural loans can be increased by controlling the use of loans by supervision of on-site use of.

Due to their widespread use in the pharmaceutical, cosmetic and food industries, medicinal and aromatic plants have gained importance with an increasing number of studies being conducted concerning the yield and quality characteristics of these plants. In breeding studies, selection is successful when there a correlation is established between the essential oil content, composition, and morphological and agronomic characteristics. The aim of this study was to address the correlation between the yield and quality of medicinal and aromatic plants to present a different perspective for breeding studies. Therefore, in this study, the relationship among the characteristics and the essential oil content of Izmir oregano (Origanum onites L.) and lemon balm (Melissa officinalis L.) plants were investigated, and correlation and path analyses were performed. There was a significant negative correlation between the essential oil content and fresh herb (-0.279*), dry herb (-0.281*), and dry stem yield (-0.283*) of Izmir oregano. However, no significant correlation was found between the essential oil content and these agronomic characteristics in lemon balm. Fresh herb yield had a significant positive correlation with dry herb (0.661**), dry leaf (0.690**), and dry stem yield (0.610**). Dry herb yield was significantly and positively correlated with dry leaf (0.510*) and dry stem (0.461*) yields. A significant positive correlation was also observed between dry leaf and dry stem (0.688**) yields. According to the results of the path analysis, while the maximum negative effect on the essential oil content of Izmir oregano was provided by dry herb (-48.05%) yield, the highest direct positive effect belonged to dry leaf (21.69%) and dry stem (15.13%) yields. Dry leaf yield (-51.61%) and plant height (-45.71%) were the parameters that had the highest direct negative effect on the essential oil content of lemon balm while fresh herb (33.50%) and dry herb (30.27%) yields were the source of the highest direct positive effect.

In this study, the effects of Artemia sp. nauplii and micro capsulated feed on growth performance and survival rate of guppy (Poecilia reticulata) and goldfish (Carassius auratus) larvae were compared at the end of three weeks of rearing period. Length of goldfish larvae (4.82 mm) fed Artemia sp. (from 4 to 12/mL/day) were between 7.97 and 9.76 mm at the end of the trial while these values were between 6.80 and 7.21 mm for those fed microencapsulated feed (from 10 to 30 mg/L/day). On the other hand length of guppy larvae fed Artemia sp. (from 5 to 25/mL/day) were between 13.02 and 17.00 mm, whereas these values were remained between 11.98 and 12.38 mm for those fed microencapsulated feed (from 10 to 40 mg/L/day). A similar result was also observed in survival rates. Survival rate of goldfish larvae fed Artemia sp. were 88.91-97.61% in while those fed microencapsulated feed were 6.19-87.14%. On the other hand survival rate of guppy larvae fed Artemia sp. were 99.17-100.00% whereas those fed microencapsulated feed were 57.50-87.50%. Eventually, microencapsulated feed was not as successful as Artemia sp. on the growth and survival rate of larvae of both species.

Highly digestible high-lysine (HDHL) sorghum-wheat composites have previously been shown to produce better composite dough and bread compared to normal sorghum-wheat composites. This study aimed to test whether improved HDHL lines can provide further enhanced functionality through the effects of transglutaminase (TG) enzyme to improve dough rheological properties. Sorghum-wheat composite doughs were made using HDHL and normal sorghum flours at substitution levels of 10, 20, and 30%, with and without 0.15% TG. Rheological properties of dough were tested using a mechanical spectrometer at 0.05% strain amplitude (within the linear viscoelastic region) over a 0.01- 50 rad/sec frequency range. A more elastic system was observed in HDHL sorghum-wheat composites above 10% substitution levels compared to normal sorghum-wheat composite dough. Addition of TG to HDHL sorghum-wheat composites resulted in a decrease in phase angle values at all substitution level, indicating that TG increased the dough elasticity. However, TG did not change viscoelastic properties of normal sorghum-wheat composites. Bread from HDHL sorghum-wheat composites had significantly higher (P

Water kefir is a fermented probiotic beverage produced by fermentation of dried sugary fruits and sugar using water kefir grains. Sucrose is used as a sugar source in the traditional production of water kefir. The aim of this study is to determine the effects of grape molasses, honey and unrefined sugar on water kefir grains instead of sucrose. In the study, 4 groups were formed: grape molasses (10 g), honey (10 g), unrefined sugar (10 g) and refined sugar (10 g). 2 g of water kefir grain and 500 mL of drinking water were used for each group. And each group samples were fermented for 25°C 48 hours. The study continued for 5 weeks. The pH values and the titratable acidity values of water kefir samples and the weight of water kefir grains were determinated once every two day, while microbiological analyzes (Lactobacillus spp., Lactococcus spp. and yeast contents) and ethanol content of samples were determinate once every 15 days. In this study; it has been observed that the use of different sugars has no significant effect on the weights of the water kefir grains. In addition, it was determined that the Lactococcus spp. and yeast amounts in the water kefirs were higher in the samples produced by using honey and grape molasses. As a result, it was revealed that grape molasses, honey and unrefined sugar could be used as fermentation substrate in production of water kefir. At the same time, water kefir can be shown as an alternative fermented product for vegan consumers with allergies to dairy products.
