Artan dünya nüfusu göz önüne alındığında, protein kaynaklarının yeterli olamayacağının bilincinde olan araştırmacılar yeni protein kaynaklarına odaklanmışlardır. Bu nedenle yenilebilir böceklerin gıdada doğrudan veya bir bileşen olarak kullanılabilme potansiyeli ilgi görmeye başlamıştır. Yenilebilir böcekler Afrika, Asya ve Güney Amerika’da uzun yıllardır geleneksel gıda olarak tüketilmektedir. Ancak özellikle Avrupa ülkelerinde, tüketiciler böceklerin gıda olarak tüketilmesine karşı olumsuz tutum sergilemektedir. Yenilebilir böcekler, geleneksel hayvansal protein kaynaklarına kıyasla daha az olumsuz çevresel etkiye sahip gıda kaynaklarıdır. Yetişme alanı, su, enerji ve yem gibi kaynakları daha az tüketmelerinin yanı sıra düşük sera gazı üretimleri ekolojik sistemin sürdürülebilir özellikleri açısından önemlidir. Yenilebilir böcekler kaliteli protein, zorunlu amino asitler, yağ asitleri, mineral ve vitaminlerin kaynağı olarak alternatif gıda kaynağı olarak kabul edilmektedir. Besleyici özellikleri üzerine yapılan çalışmalar hem küresel gıda talebinin karşılanması hem de malnütrisyonun önlenmesinde çözüm olabileceğini göstermektedir. Bu derlemede, yenilebilir böcekler besleyici özellikleri açısından değerlendirilmiştir.

Tarhana is a traditional food produced by different traditional methods and the materials used in production are changing from a region to another region. The total yeast and molds, total mesophilic aerobic bacteria, Escherichia Coli and enterococci bacteria count of wet dough Kastamonu tarhana and dry powdered tarhana samples were investigated in this study. All microorganisms examined in our study were detected in one of the wet dough tarhana samples. The highest total yeast and molds, total mesophilic aerobic bacteria, Escherichia coli and enterococci bacteria counts were determined for the wet dough tarhana samples to be 2.2×106, 6.6×107, 1.2×106 and 1.9×106 cfu/g, respectively. No growth of microorganism capable of reproduction was observed in the powdered tarhana produced industrially. In addition, the Escherichia coli and enterococci bacteria were not detected for any of the dry powder tarhana samples. It was seen that the microbial load of the wet tarhana produced at home in Kastamonu was higher than the powdered tarhana. The reason for this situation was thought to be due to poor production and hygiene conditions. The presence of Escherichia coli and enterococci bacteria in samples indicates that there is possible fecal contamination of the raw materials used in wet dough tarhana production. Electron microscope images of molds obtained in our study are similar to molds producing mycotoxins. These results show that the wet dough tarhana have a greater risk for microorganism development and human health compared to dry powder tarhana.

Agricultural marketing plays a vital role in economic development and livelihood of people in developing countries. Marketing of agricultural products which provide income to most farmers and marketers in Nigeria has been characterised with a lot of deficiencies which have constrained sustainable development and economic growth. This study, therefore, analysed carrot and cucumber marketing including constraints to their effective marketing in Enugu State, Nigeria. Data collected, primarily, were analysed using descriptive statistics, marketing margin and Likert type rating technique. The result shows that vegetable marketing was dominated by females (65%) who were still in their economically active age and did not belong to a cooperative society. Half of them perform a retail marketing function, 30% perform both retail and wholesale functions while 20% perform wholesale function. Vegetable marketing contributed to marketers’ income by providing N25,667.7 (USD 66.93) per month on average. The marketing margins were 26.30% and 20.18% for cucumber and carrot, respectively. The high cost of shop rent, high transportation cost, low capital, price fluctuation, poor credit facilities and a low supply of vegetables due to seasonal variation were the major constraints faced by vegetable marketers. Vegetable marketers, therefore, need support by providing affordable credit facilities and building of modern market stalls by the government. This would give them a conducive and hygienic environment. Also, vegetable marketers should form a cooperative society where they can pool resources and get financial assistance. This would lead to efficient marketing of the product.

Bu çalışmada 32 haftalık yaştaki Japon bıldırcını sürüsünden elde edilen toplam 402 kuluçkalık yumurta, gelişme döneminde kabuk sıcaklığı, kabuk sıcaklığı ile makine sıcaklığı arasındaki fark ve oransal ağırlık (nem) kaybının kuluçka sonuçları üzerine etkilerinin belirlenmesi amacıyla kullanılmıştır. Yumurtalar ağırlık sınıfına göre iki gruba ayrılmış (≤12 g ve >12 g) ve makine katlarına rastgele ve eşit olarak dağıtılmıştır. Beklendiği üzere, kuluçkalık yumurta ağırlığı civciv çıkış ağırlıklarını önemli ölçüde etkilemiştir. Hafif yumurtalar ağır yumurtalara göre daha fazla nem kaybetmişlerdir. Embriyo, gelişme döneminin ilk yarısında hissedilir düzeyde ısı üretememekteyse de (endotermik faz), ikinci yarısında belirgin biçimde ısı üretmeye başladığından (ekzotermik faz), kabuk sıcaklığı makine iç sıcaklığından daha yüksek olmuştur. Bu durum ağır yumurtalarda daha belirgin olmaktadır. Gelişim döneminin ilk yarısında kabuk sıcaklığı hafif yumurtalarda ağır yumurtalara göre daha yüksekken, ikinci yarıda yumurta ağırlık gruplarında belirlenen kabuk sıcaklıkları katlara göre değişmiştir. Genel olarak, büyüyen embriyonun artık belirgin biçimde ısı ürettiği bu geç dönemde iri yumurtalarda ve üst katta yer alan yumurtalarda daha yüksek kabuk sıcaklıkları belirlenmiştir. Alt kattaki hafif yumurtalar, diğer tüm kombinasyonlardaki yumurtalardan daha düşük kabuk sıcaklığı değerlerine sahip olmuşlardır. Son dönem embriyonik ölümler ağır yumurtalarda önemli ölçüde daha yüksek bulunmuştur.

This study was carried out to determine the effects of lactic acid bacteria+ enzyme (LAB+E) inoculants on the fermentation characteristics and feed values of silages prepared from alfalfa harvested at three maturity stages. Alfalfa was harvested at the early, middle and late flowering stages. Sil-All (Alltech, UK) were used as LAB+E inoculants. Inoculants were applied to the silages at the rates of 1×105, 5×105 and 1×106 cfu/g levels in 1 liter capacity plastic bags. The bags were stored at 20±2°C under the laboratory conditions. Three bags from each group were sampled for chemical and microbiological analyses on the 45th day after ensiling. The results showed that LAB+E inoculants reduced pH values and ammonia-nitrogen content, whereas increased lactic acid contents and lactobacillus count of alfalfa silages. High doses LAB+E inoculant decreased neutral detergent fiber and acid detergent fiber content, increased in vitro organic matter digestibility and metabolic energy of alfalfa silages. It has been demonstrated that the most effective application dose of LAB+E inoculant to improve fermentation and feed value of alfalfa silage was 1×106 cfu/g, but 1x105 and 5×105 cfu/g level can also be considered as effective dose.

This study was conducted to investigate the effects of Aspergillus niger strain and inoculum level on the nutritional composition of olive leaves. The experiment had a 2×3 factorial arrangement of treatments with two A. niger strains (ATCC 200345 [A] and ATCC 9142 [B]) and three inoculum levels (104, 106, and 108). Olive leaves were milled to 2 mm and fermented in solid-state by two different A. niger strains and analysed for nutritional composition. Crude protein (CP) was increased linearly as the inoculum level increased. Ether extract (EE) and crude fiber (CF) were decreased linearly in A strain or quadratically in B strain with increased inoculum levels. Crude ash and nitrogen-free extract content did not differ among groups. Strain A increased neutral detergent fiber (NDF) at higher inoculum level, whereas NDF was decreased as inoculum level increased in B strain. The lowest acid detergent fiber (ADF) was obtained from the B strain or 106 inoculum level. The results showed that the effect of two strains on CP and ADF changed similarly with increased inoculum levels. However, two strains affected EE, CF, and NDF content differently with increased inoculum levels. The optimal situations were 108 inoculum level for higher CP, A104 or B104 for higher EE, B106 for lower CF, B106 or B108 for lower NDF, 106 inoculum level or B strain for lower ADF. B strain at 106 inoculation level can be preferred to obtain an average CP and EE content and lower CF, NDF, and ADF content.

It is known that plants have been used by humans for a very long time in the treatment of diseases. A wide variety of plant species grown in different regions have been very successful in the treatment of many diseases. In this study, Echium italicum L. plant collected from different regions was used as material. The plant was extracted with ethanol in a soxhlet device. Then, antioxidant and oxidant levels of the plant extract were determined using Rel Assay kits. As a result of the analysis, the TAS values of the plant were determined 5.442±0.240 (Gaziantep), 4.896±0.081 (Hakkari) and 6.056±0.139 (Mersin), TOS values were 21.372±0.747 (Gaziantep), 12.255±0.341 (Hakkari) and 19.107±0.438 (Mersin), OSI values were 0.395±0.027 (Gaziantep), 0.250±0.005 (Hakkari), and 0.316±0.005 (Mersin). It was observed that antioxidant and oxidant values changed as the regions where the plant was collected changed. In addition, it was determined that E. italicum could be a natural antioxidant source.

This study has been carried out in 2017-2018 in order to determine seed dormancy and effective germination depth wild mustard (Sinapis arvensis L.). The in-vitro dormancy breaking experiments (tip breaking, sanding, H2SO4 application, holding in flowing and still water, GA3, KNO3 and GA3+KNO3 combination application) has been applied to wild mustard seeds collected from wheat field in Tokat province and has been applied to wild mustard seeds collected from wheat field in Tokat province and the most effective method was determined as 1000 ppm GA3+KNO3 with 98% impact on seed germination at 15°C within 72 hours. In contrast germination rate has been calculated as 5% in control plants. Furthermore 15°C was assessed as optimum temperature for seed germination was the most effective temperature and during depth studies 100% of wild mustard seeds germinated at 3-5 cm. Because of the difficulies with the work with seeds and plants that have dormancy, these data will contribute future studies.

In completed research, ferrous gluconate -a food additive- used to preserve black color to prevent discoloration during storage in ripe black olives, and Allium cepa L. species. A. cepa L. roots were treated with different doses of ferrous gluconate. The effective concentration EC50 (0.068 g/l) was determined. A. cepa root tips were treated with EC50/2 (0.034 g/l), EC50 (0.068 g/l), 2XEC50 (0.136 g/l) dose for 24, 48, 72 hours, and afterward, the root tips were prepared for observation under the light microscope according to the method of preparing mitotic preparation. Chromosomal abnormality index (CAI) and genotoxic effect of ferrous gluconate in A. cepa root tip cells were determined. Repeated measurement ANOVA and TUKEY multiple comparison tests were used to investigate the effect of time and dose together on genotoxicity. C-mitosis, polyploidy, polar shifting in anaphase, polar shifting in telophase, equatorial plate shifting, laggard chromosome was observed by microscope. The highest CAI (70.16±4.85) was observed at 72h for 2XEC50 dose. Chromosomal aberration is also observed in control group. While the most common chromosomal aberration is determined as C-mitosis; The least observed chromosomal aberration is determined as polyploidy. Research results revealed that ferrous gluconate has a genotoxic effect on the root tip of A. cepa.
