Shambel Kiros Simone | Solomon Tiruneh | Abto Asres | Demlie Chanie | Belay Deribe
A survey was conducted in three selected kebeles of Kombolcha Regiopolitan City in South Wollo Zone. The selected kebeles were in proximity to brewery factory, Ethiopia. A semi-structured questionnaire was used to collect perception data from purposively selected three kebeles and a total of 57 randomly selected dairy farmers. Data collected were analyzed with a statistical package for social sciences (Version 20) and Microsoft Excel (2010). Smallholder dairy farmers had average herd size of 10.7 and 0.08 hectare total dairy farm per household. Average daily milk yield and lactation length of dairy cows was 10.8 liter/day and 9.5 months, respectively. The majority of farmers (59.6%) reared dairy cows with 50-75% exotic blood. The most smallholder dairy farmers satisfied their feed demand from the market and had a trend of providing both dense and poor quality affordable feed ingredients. Smallholder dairy farmers gave priority to feed different kind of cattle in the order of lactating cows, calve, pregnant, heifers and dry cows and used (100%) wet brewery spent grain as a source of dairy feed. Though, there was a brewery by-product supply deficit for half of year. The majority smallholder dairy farmers delivered brewery by-product directly from the brewery factories and followed by wholesalers and retailers. The majority of smallholder dairy farmers (96.4%) stated that the brewery spent grain was fed and stored freshly using different conservation techniques, and the remaining stored in ensiled (1.8%) and dried (1.8%) forms. Smallholder dairy farmers had no brewery spent grain ensiling practice and feeding brewery yeast to dairy animals. Smallholder dairy farmers indicated that high price due to abnormal market chain and shortage of brewery spent grain supply were the major challenges to sustain dairy industry in the study area, and the majority (40.6%) claimed to get swift solutions at high cost and less accessible brewery by-product.

Savaş Kuşcu | Kıvılcım Çaktü Güler
Buğday özellikle insanların beslenmesinde büyük rol üstlenmiştir. Yetiştirilmesi son derece zahmetsiz olsada yapılan araştırmalar, iklim değişikliğinden buğdayında olumsuz etkileneceğini ortaya koymuştur. Anadolu’da buğday ekili alanlarda verim ve kaliteyi arttırmak için gübreleme yapılmaktadır. Gübreleme yapılırken uygulanan miktara, uygulama zamanına ve gübre türüne dikkat edilmesi gerekir. Kontrolsüz yapılan gübreleme toprağa ve çevreye zarar vermektedir. Toprağı verimsiz hale getirirken, atmosferede sera gazı salınımına neden olacaktır. Bu durum ise buğday üretiminde ki karbon ayak izinin artmasına neden olacaktır. Yaptığımız bu çalışma da buğday üretimi yapılırken çiftçiler tarafından kullanılan gübrelerin, kullanım miktarına bağlı olarak ürettiği karbon ayak izini hesapladık.

Hardaliye, grape-based fermented beverage, rich in antioxidant phenolic compounds. Bioaccessibility and antioxidant capacity of bioactive compounds in hardaliye, produced using varying amounts of mustard seeds (1%, 1.5%, and 2%) with Merlot and Papazkarası grape varieties, were evaluated under in vitro gastrointestinal digestion conditions. After digestion, Merlot and Papazkarası samples with 2% addition of mustard seed showed significantly higher total phenolic compounds (TPC) (358.48±14.73 and 89.01±2.42 mg GAE/L, respectively) compared to other samples (P<0.05). 2% mustard seed added Merlot samples resulted in the highest 1,1-diphenyl-2-picrylhydrazyl (DPPH) and cupric reducing antioxidant capacity (CUPRAC) values (19.06±3.91 and 9.96±1.83 mmol TEAC/L, respectively) which differed significantly from other samples (P<0.05). The Merlot sample with 2% addition of mustard seed showed significantly higher TPC, total flavonoid compounds (TFC), DPPH, and CUPRAC bioaccessibility values compared to other Merlot samples (P<0.05). For Papazkarası samples with 2% mustard seed addition, significant differences were observed only in terms of TPC and TFC bioaccessibility values (15.87±2.30% and 15.27±1.29%, respectively) compared to samples with 1% and 1.5% mustard seed addition (P<0.05). The study demonstrated that the bioaccessibility of bioactive compounds in hardaliye can vary depending on the grape variety and to some extent, the use of mustard seed. This suggests that the food matrix and interaction with other food matrices in the environment can affect the stability and bioavailability of bioactive compounds during simulated digestion.

Barış Ötün
Milk and dairy products mostly contain mycotoxins such as aflatoxin M1, aflatoxin M2, ochratoxin, cyclopiazonic acid, trichothecene, zearalenone, patulin. Mycotoxins in cheese are produced by certain types of fungi. These either directly contaminate the cheese or feed, or indirectly contaminate the milk used in cheese production. Aflatoxin, causes serious impacts on human and animal health, thus costs the world economy billions of dollars. The first legal regulation regarding aflatoxin M1 in Turkiye came into force in 1990. Subsequently, various legislations were published in 1997, 2002, 2008, 2011 and 2023. In this study, 60 publications were examined that investigate the presence of aflatoxin M1 in various cheeses in Turkiye in the last 50 years (1973-2023). In the studies, aflatoxin M1 was detected in almost all cheeses, and only a few were found in rates exceeding the Turkish Legal Limits. Researchers stated different limits for aflatoxin M1 in cheese. To minimize the presence of aflatoxin M1, the following recommendations should be considered. Developing new detection methods, enacting new legal regulations, increasing the frequency of legal inspections, improving the production, transportation and storage conditions of milk and dairy products, improving feed quality, increasing awareness of the health effects of aflatoxin M1.

In this study, Bacillus subtilis natto was encapsulated in alginate, either coated with or mixed with xanthan gum as a supplemental component. The encapsulated bacteria were then evaluated for their survival in simulated gastric fluid (SGF) and simulated intestinal fluid (SIF). The results showed that B. subtilis natto biomass had a thrombolytic ability compared to the control sample. The viability of encapsulated B. subtilis natto was improved in which alginate 2.5% (w/v) had a high encapsulation efficiency, and there was no difference between the samples with or without the xanthan gum supplement. In the SGF and SIF tests, the viability of B. subtilis in samples supplemented with xanthan gum was higher than in samples that contained only alginate. Additionally, there was no significant difference in viability between the samples that mixed xanthan gum with alginate and those that were coated with it. The results indicated that adding xanthan gum is necessary to increase alginate's protective effect on B. subtilis natto.

Beyza Türköz | Muhammed Mustafa Özçelik | Sebahattin Serhat Turgut
Antep fıstığı, başta baklava olmak üzere birçok tatlıda sıkça kullanılan bir üründür. Özellikle öğütülmüş Antep fıstığı, talebin yüksek olması ve yüksek maliyeti nedeniyle sıklıkla tağşişe maruz kalmaktadır. Yeşil bezelye ve ıspanak, organoleptik özellikleri, renk benzerliği ve ucuzluğu nedeniyle Antep fıstığı ile karıştırılarak en çok sahtecilik gerçekleştirilen ürünler arasındadır. Ancak bu ürünlerin öğütülmüş Antep fıstığına belirli oranlarda karıştırılması durumunda sahteciliğin hızlı ve yerinde tespiti, gözle muayene gibi yöntemlerle çoğu zaman mümkün olmamaktadır. Bu nedenle mevcut çalışma, Antep fıstığındaki yeşil bezelye ve ıspanak tağşişinin, düşük maliyetli bir spektral sensör teknolojisi ve kemometrik yöntemler kullanılarak tespitini amaçlamaktadır. Bu kapsamda yeşil bezelye ve ıspanak örnekleri Antep fıstığı ile %5-50 (a/a) arasındaki konsantrasyonlarda %5’lik artışlarla karıştırılmıştır. Saf Antep fıstığı ve karışık numunelerin reflektans spektrumları 410-940 nm arasında elde edilmiştir. Numunelerdeki sahtecilik oranlarının tespiti amacıyla geliştirilen modelin eğitilmesinde derin öğrenme yöntemi kullanılmıştır. Modele beslenen verilerde boyut indirgeme amacıyla Temel Bileşenler Analizinden faydalanılmış olup, regresyon probleminin uyum iyiliğini test etmek amacıyla belirleme katsayısı (R2), hata kareler ortalamasının karekökü (RMSE) ve artıklık tahminsel sapma (RPD) istatistikleri kullanılmıştır. Sırasıyla eğitim, doğrulama ve test verileri için R2 0,85, 0,83 ve 0,80; RMSE 5,81, 6,13 ve 6,71; RPD 2,55, 2,44 ve 2,21 olarak tespit edilmiştir. Elde edilen bulgular neticesinde, söz konusu ekonomik spektral sensör ve geliştirilen kemometrik yöntemin Antep fıstığında özellikle %10 üzerindeki yeşil bezelye ve ıspanak tağşiş oranının belirlenmesi için tahribatsız, hızlı ve kolay bir yöntem olarak kullanılma potansiyeline sahip olduğu ortaya konmuştur.

Tuğba Dağdeviren | Hatice Kübra Yolcu
Quantitative analyses in biological science are especially important in terms of determining and comparing the geometric properties of biological structures. Stereology and morphometry are two important complementary methods frequently used in this field. Stereology refers to the quantitative analysis of the three-dimensional geometric properties of biological structures. In particular, it is used to determine the criteria such as volume, surface area and length of many cells, organelles and tissues with microscopic properties. In addition, this method allows to obtain information about three-dimensional structures by measurements made on randomly selected sections. Thanks to these techniques, accurate estimates of the general structure can be made with data obtained from certain sections instead of examining biological samples completely. Morphometry, on the other hand, is suitable for examining biological structures in terms of shape and size. It is a suitable method for determining the shape changes of organisms and structural elements. Morphometry digitizes the data by making measurements in the digital environment and performs statistical analysis on these data. Measurements are made more quantitative by volume fraction analysis. The importance of stereology and morphometry in quantitative morphology enables the objective realization of biological structures in quantitative analysis in both methods. These methods thus allow the examination of the material at hand, which is mathematical and statistical. In addition to biology, tissue science Quantitative biology has a special place in three-dimensional studies in histology. This review is particularly concerned with stereology and morphometry, and the aim of the review is to give dimension to a specific topic under investigation, thus providing a good background for diagnostic decision making by strengthening traditional approaches, and to address the contributions of these methods in scientific studies.
