- MakaleAçık Erişim2025Producing Geographical Indication Products from the Farmers' Perspective: Kelkit Dry Beans
Adanacioglu, Hakan; Doğan, Nilgün
A locally sourced, high-quality food supply is seen as both viable and desirable. Geographical indications (GIs) help consumers identify products linked to specific regions, creating intellectual property rights that strengthen rural economies and support sustainable agriculture. Despite this potential, adoption among smallholders remains limited, and its effectiveness depends heavily on farmers’ experiences, perceptions, and motivations. This study examines the production and marketing of GI products from the perspective of farmers, focusing on Kelkit Dry Beans, a geographically indicated product in Türkiye. Primary data were collected in 2021 through face-to-face interviews with 100 dry bean farmers in the Kelkit, Şiran, and Köse districts of Gümüşhane province—50 using GI-registered seeds and 50 not. Findings indicate that farmers adopting GI production expected higher prices based on quality improvements but were unable to achieve these outcomes. Access to alternative markets did not improve, and buyer-related problems persisted. Compared to non-GI farmers, those producing GI beans attached greater importance to factors such as easier marketing, higher expected prices, financial support from unions, and the assurance of long-term demand from contract buyers. Nevertheless, their largely negative experiences - particularly unmet price expectations and limited market access—undermine confidence in GI production and discourage wider adoption. In conclusion, while GIs offer opportunities for rural development, competitiveness, and sustainability, their broader adoption requires addressing farmers’ concerns regarding profitability, reliable markets, and institutional support. Without such improvements, the potential benefits of GIs are unlikely to be fully realized.

Yilmaz, Firat; Ordu, Gülsüm
The study examines the microbial and physicochemical properties of Hamsiköy rice pudding, comparing non-baked and baked samples. Microbiological analyses revealed notably higher counts of total aerobic mesophilic bacteria (TAMB), psychrophilic bacteria, and lactic acid bacteria (LAB) in non-baked samples, with TAMB and LAB reaching 5.69 log cfu/g and 6.06 log cfu/g, respectively. Conversely, the baking process led to a decline in microbial load, as evidenced by the lower counts observed in the baked samples. additionally, chemical analyses revealed that the baked samples exhibited higher dry matter, fat, and protein content compared to the non-baked samples. Additionally, the cooked rice pudding samples had lower L* values, indicating a* darker colour. Despite some variations, the chemical properties observed in this study are generally consistent with those reported in previous studies. The study concludes that the baking process enhances the microbiological and physicochemical quality of Hamsiköy rice pudding, thus making it a a product with enhanced safety and quality. Hydroxymethylfurfural (HMF), an indicator of heat treatment, was analyzed as well and was found to be higher in baked samples. Colour parameters (L*, a*, b*) revealed darker appearance in baked samples, aligning with consumer expectations for traditional Hamsiköy rice pudding.

Akyol, Mehmet; Bakkaloğlu, Ayşen
In this paper, the effects of agricultural value added, urbanisation and energy consumption on environmental quality in MINT (Mexico, Indonesia, Nigeria, Turkey) countries were analysed for the period between 1992-2019. In the first stage of the study the panel analysis was used then the existence of horizontal cross-section dependence between the variables was tested and then the CIPS test, was used to test the stationarity of the series. In the paper where the existence of homogeneity was tested with the Delta test, the long-run relationship between the series was tested with the Pedroni panel cointegration test. Finally, the effects of agricultural value added, urbanisation and energy consumption on the environment were analysed by fully modified least squares estimator (FMOLS) analysis. According to the FMOLS results, the increase in agricultural value added and urbanisation rate has a negative impact on environmental quality, while renewable energy consumption has a positive impact on environmental quality. The results of the study show that more environmentally friendly policies should be developed and implemented in the agricultural production process in the country group in question, renewable energy investments and consumption should be increased, and the urbanisation rate should be taken under control and environmentally friendly new generation city plans should be put into effect urgently.

- MakaleAçık Erişim2025A General Assessment of the Retail Price Premiums of Organic Food Products in Türkiye
Adanacioglu, Hakan; Doğan, Nilgün
Organic agricultural production has emerged as an alternative to conventional production and aims to promote a sustainable production approach based on the health of soil, the protection of nature and human well-being factors with an environmentally friendly production method. Organic production combines traditional knowledge with scientific innovation to benefit the natural environment and promote a higher quality of life for all. Organic agricultural products, which have gained significant market share globally and expanded into various markets, are mainly produced for export in Türkiye. The growth of the organic market depends on the balance between supply and demand. In this respect, the aim of this study is to examine the product market prices, which is a key factor affecting the purchasing behaviour of consumers in order to grow the organic market and reach the desired level. Price premiums were examined for the following food groups: cereals/legumes, fruit, vegetables, milk, dairy products and eggs, dried fruit and nuts. This study relies on secondary data and retail prices were collected through online websites. According to the results, the price premium, which was calculated by comparing the prices of organic and conventional versions of selected food products, was found to be in favour of organic products. This price premium was found to be particularly high for noodles, dry beans, buckwheat and rice from the cereals/legumes group; grapefruit, apple and pear from the fruit group and yellow chickpeas, pumpkin seeds from the nuts group. These results provide useful insights for food producers, marketers and policy makers when making decisions about organic food.

Merddan, Kurtuluş
Purpose: The aim of this study is to identify the factors contributing to the price increases observed in food products. In this study, the global determinants of prices in agricultural and food products and their effects on the Turkish economy were addressed. The aim of the study was to identify the factors causing price increases in food products. Design/Methodology/Approach: In the study, the dependent variables included in the model were the CPI for food and non-alcoholic beverages, the CPI for unprocessed food, and the PPI for agricultural products, while the independent variables were the exchange rate (average of USD and Euro), the agricultural products export index, the agricultural products import index, Brent crude oil prices, and the international food price index. The short- and long-term causal relationships among these variables were examined through the Vector Error Correction Model (VECM) cointegration test and the Granger causality test, based on monthly data for the period 2003:01–2025:01. Findings: According to the research findings, among the variables affecting agricultural and food prices in Turkey were the international food price index, Brent crude oil prices, and the agricultural products export index. In the models where the CPI for food and non-alcoholic beverages and the CPI for unprocessed food were the dependent variables, it was determined that shocks originating from the independent variables converge to equilibrium in the long term. The findings reveal that in Turkey, the exchange rate and the agricultural products export index are not causal factors for the CPI for food and non-alcoholic beverages, nor for the CPI for unprocessed food. In contrast, Brent crude oil prices and the international food price index were identified as causal factors. Additionally, no long-term relationship was found between the PPI for agricultural products and the independent variables, and it was determined that the exchange rate, agricultural products export index, Brent crude oil prices, and the international food price index were not causal factors for the PPI for agricultural products. Originality/Value: Although similar studies exist for Turkey, the distinguishing feature of this research is that it is the first to simultaneously analyze the CPI for food and non-alcoholic beverages, the CPI for unprocessed food, and the PPI for agricultural products together with the independent variables of exchange rate, agricultural products export index, agricultural products import index, Brent crude oil prices, and the international food price index.

Aykut, Memnune Kabakuş; Özbey, Fatih; Turksoy, Secil
Bu derlemenin amacı glutensiz ekmeğin diyet lifi içeriğini artırmak için fonksiyonel bir bileşen olarak pisilyumun (Plantago ovata) potansiyelini araştırmaktır. Son yıllarda glutenle ilişkili hastalıkların yaygınlığı, artan sağlık bilinciyle oluşan farkındalığın artması ve gelişmiş tanı yöntemleri sayesinde önemli ölçüde artmıştır. Bu durum, glutensiz ürünlere olan talebin artmasına yol açmıştır. Bununla birlikte en yaygın tüketilen glutensiz ürünlerden biri olan glutensiz ekmek, temel olarak glutenin yokluğu nedeniyle genellikle düşük somun hacmi, zayıf tat ve doku, düşük besin değeri ve yüksek üretim maliyetlerinden mustariptir. Bu zorluklar hem gıda endüstrisi hem de glutensiz diyet uygulayan bireyler için sıkıntı oluşturmaktadır. Bu derleme, pisilyumun sağlığa faydaları ve gıdalardaki potansiyel uygulamaları hakkında kapsamlı bir literatür analizi sunmaktadır. Pisilyum, yüksek diyet lifi içeriği ve glutenin yapısal ve bağlayıcı özelliklerini taklit etme kabiliyeti nedeniyle umut verici bir bileşen olarak öne çıkmaktadır. Bir diğer önemli avantajı, lezzet profilini değiştirmeden gıda ürünlerine kolaylıkla dahil edilebilmesidir. Pisilyum tüketicilerin kalori alımını artırmadan yeterli miktarda diyet lifi alım ihtiyaçlarını karşılamalarına yardımcı olabilirken, aynı zamanda kolesterol seviyelerinde iyileşme, daha iyi glisemik kontrol ve tokluk hissi gibi ek sağlık yararları da sunar. Bu nedenle, pisilyum daha sağlıklı glutensiz ekmek üretiminde ve bulaşıcı olmayan kronik hastalıkların önlenmesinde değerli bir rol oynayabilir.

Bu çalışmanın amacı, Gümüşhane düğünlerinde yer alan yemek kültürü ve bu yemeklere eşlik eden ritüel uygulamaları kültürel miras perspektifinden incelemektir. Nitel araştırma yöntemiyle yürütülen çalışmada, Gümüşhane merkez köylerinde yaşayan 29 katılımcıyla yarı yapılandırılmış görüşmeler gerçekleştirilmiştir. Bulgular, düğün yemeklerinin yalnızca bir beslenme pratiği olmadığını, kültürel kimliğin aktarımı, toplumsal dayanışmanın güçlendirilmesi ve ritüel sürekliliğin sağlanması açısından önemli işlevler üstlendiğini ortaya koymuştur. Düğünlerde imece usulüyle hazırlanan pilav, etli nohut, dolma, lahana sarma ve siron gibi yöresel yemeklerin paylaşım ve bereketin sembolik bir ifadesi olarak değerlendirildiği belirlenmiştir. Yemeklerin hazırlanış sürecinde keyveni olarak adlandırılan deneyimli kadınların belirleyici bir role sahip olduğu ve bu kişilerin kültürel bilgi taşıyıcıları ile toplumsal otorite figürleri olarak kabul edildiği tespit edilmiştir. Modernleşme süreciyle birlikte düğünlerin salonlara taşınması, hazır yemek uygulamalarının yaygınlaşması ve imece geleneğinin zayıflaması ritüel bilincin giderek kaybolmasına yol açmaktadır. Çalışma bulguları doğrultusunda geleneksel düğün yemeklerinin belgelenmesi, imece geleneğinin sürdürülmesine yönelik farkındalığın artırılması ve kültürel bilginin kuşaktan kuşağa aktarılmasının desteklenmesi önerilmektedir.

Merdan, Kurtuluş
The growing world population has driven humanity to produce more food, potentially leading to the neglect of quality and safety in food production. Evolving life conditions and technological progress have altered the consciousness level of humanity, bringing about new demands in some communities due to high income. Organic beekeeping has developed within this structure and tends to flourish as a model in Türkiye. Organic beekeeping has increased the income from beekeeping. It is practiced in natural unspoiled areas with no conventional feeding and chemical pesticides and requires supervising all processes through inspection and certification. Besides organic honey, the most common organic beekeeping product, organic bee products include bee pollen, propolis, royal jelly, beeswax, and bee venom. This study presents the economic analysis of organic honey production volume in Türkiye. For this purpose, the short and long-term relationships of organic honey production and the number of producers with economic growth, employment, and agricultural employment were analyzed. In addition, organic honey production and the number of organic honey producers were examined as driving forces for growth, employment, and agricultural employment. In this context, annual time series data between 2004 and 2022 were used as the sample. According to the analysis, organic honey production, an independent variable, had no long-term relationship with employment and agricultural employment variables, whereas it had a long-term relationship with the growth variable. The number of organic honey producers, another independent variable, was found to have no long-run relationship with the employment variable; however, it had a long-term relationship with the growth and agricultural employment variables. The findings of the study indicated that organic honey production did not drive growth, employment, or agricultural employment. On the other hand, the number of organic honey producers led to growth, yet not to employment or agricultural employment.

Bursa, Batuhan; İlyasoğlu, Huri
The demand for gluten-free foods has increased due to health-based issues and lifestyle choices. This study aimed to develop a gluten-free cookie with enhanced nutritional value. For this reason, the composite flour from corn flour (CF) and lentil flour (LF) was prepared for cookie formulation. To eliminate the possible negative impact of LF on the sensorial properties of the cookie, lemon peel powder (LPP) was incorporated into the cookie formulation. The effects of the LF level of composite flour and the incorporation level of LPP on the physical, textural, and sensorial properties of the cookie were investigated via response methodology. The optimal levels were found as 16 g LF and 1 g LPP for 100 g composite flour. The physical, textural, and sensorial properties, proximate composition, vitamin C and total phenolic contents, and antioxidant capacity of the developed cookie and control cookies were determined. The developed cookie had a higher nutritional value than the control cookie made from CF in terms of protein, dietary fibre, ash, and vitamin C. Moreover, it presented higher total phenolic content and radical scavenging activity. According to these results, the developed cookie can be proposed for a gluten-free diet.

Hezer, Fatma; Gündoğdu, Engin
Purslane (Portulaca oleracea L.) is rich in ω-3 fatty acids, antioxidants, and minerals, and has notable neuroprotective, anti-inflammatory, antimicrobial, antidiabetic, antioxidant, anticancer, and antihypertensive properties. This research evaluated the effect of fresh purslane (FP) on the physicochemical and nutritional properties of ice cream, including α-linolenic acid (ALA; 18:3; ω-3), mineral content, and antioxidant properties, along with sensory characteristics. FP was added at 0, 5, 10, and 15% (w/w) levels. The addition of FP significantly increased the iron (Fe), calcium (Ca), copper (Cu), sodium (Na), oleic acid (OA), and ALA contents (P < 0.05). FP also increased the first dripping and complete melting times, while decreasing overrun and viscosity. Total antioxidant capacity (TAC) remained unchanged (P > 0.05), but total phenolic content (TPC) and 2,2-diphenyl-1-picryl-hydrazyl (DPPH) radical scavenging activity significantly increased (P < 0.01). Thirty-one volatile compounds were identified, with increases in octadecane, dodecane, and 2-hexenal concentrations due to FP addition. Although the addition of FP improved the ALA content and antioxidant properties, sensory results showed that FP over 5% (w/w) lowered taste and general acceptability scores. Thus, using 5% of FP in ice cream is optimal for enhancing nutritional properties.

The initial phase of the studies focused on the conservation of gene resources involves the phenotypic and genetic characterization of existing breeds. By elucidating the differences at the mitochondrial DNA (mtDNA) level, a particularly suitable source for genetic analyses, it becomes feasible to calculate genetic distances between local breeds, identify potential domestication centers through evolutionary analyses, and construct phylogeny trees depicting kinship relationships between among breeds. Şanlıurfa holds significance in pigeon breeding due to its prolonged history of traditional pigeon breeding, establishing itself as one of the pigeon domestication centers. This study aims to genetically characterize Şebap pigeon breed which is specific to Şanlıurfa province in Türkiye. The mitogenome of the Şebap pigeon was analyzed by next generation sequencing and determined to be 17,232 bp in size, comprising 13 Protein-Coding Genes (PCGs), two Ribosomal RNAs (rRNAs), 22 Transfer RNAs (tRNAs). The overall mitogenome composition includes 29.6% for A, 24.5% for T, 31.2% for C, and 14.7% for G, with a notable A–T richness of 54.1%. Notably, ND6 is encoded on the L strand while the others are encoded on the H strand. Our study has provided a comprehensive examination of whole mitochondrial DNA. Using this information, we have constructed a phylogenetic tree, locating the Şebap pigeon within the rock pigeon lineage.

Kaya, Hacer
This study aimed to determine the effects of adding different doses of organic hawthorn fruit vinegar (HFV) to the drinking water of male broilers (Ross 308) reared under cyclic heat stress (CHS) on tibia bone morphology, biomechanics, and minerals. Broilers were distributed into six groups based on a 2 × 3 factorial design, testing two ambient temperatures (24 and 35°C CHS for 8 h/day starting from day 21) and three HFV levels (0, 2, and 4 ml/L). Cyclic heat stress had no effect on the morphological and biomechanical properties of the tibia bone, except for a decrease in cortex thickness (P < 0.05). However, CHS significantly decreased the bone Ca, P, Mg, Cu, Zn, Mn, and K levels, while increasing the Fe levels (P < 0.01). The addition of 2 and 4 ml/L HFV had no effect on the morphological and biomechanical properties of the tibia bone (P > 0.05), except for an increase in bone diameter with 2 ml/L HFV (P < 0.05). HFV additions were not sufficient to increase the Ca level decreased by CHS, and the tibia bone Ca level of birds under CHS decreased further with HFV additions (P < 0.01). Conversely, 2 ml/L HFV increased Mg levels, and both 2 and 4 ml/L HFV increased Cu, Fe, Zn, and Mn levels, whereas P levels decreased (P < 0.01). K level decreased with 2 ml/L HFV and increased with 4 ml/L HFV supplementation. In conclusion, HFV supplementation has positive effects on bone mineralization in broilers exposed to HS and can be used up to 4 ml/L to mitigate the negative effects of heat stress.

Başeğmez, Mehmet; Yüksel, Duygu
This study aimed to determine the protective role of boric acid in a pregnant rat model of high fructose corn syrup consumption. Consumption of high fructose corn syrup has been associated with adverse health outcomes in humans and animals. Twenty-eight healthy female Wistar albino rats (250–300 g weight and 16–24 weeks old) were randomly distributed into four equal groups (n = 7): Control, Boric acid (BA), High Fructose Corn Syrup (HFCS), HFCS + BA. Boric acid (20 mg/kg) was administered to pregnant rats via oral gavage every day during pregnancy. The prepared 30% HFCS (F30) solution (24% fructose, 28% dextrose) was added to the drinking water throughout pregnancy. At the end of pregnancy (day 19), blood, placenta, uterus, and fetuses were collected from rats. The results indicated that HFCS increases oxidative stress by increasing the level of MDA and decreasing GSH, SOD, and CAT activity in the blood of maternal. However, BA administration significantly decreased MDA levels and increased GSH levels, SOD, and CAT activity (p < 0.05). In addition, HFCS consumption significantly increased plasma TNF-α, IL-6, and leptin levels compared to control, BA, and HFCS + BA groups (p < 0.05). However, BA administration significantly decreased plasma TNF-α, IL-6, and leptin levels (p < 0.05). Furthermore, BA (20 mg/kg) significantly decreased HFCS-induced histopathological and immunohistochemical alterations in the placenta, uterus, and fetal tissue. In conclusion, BA may prevent HFCS toxicity in maternal and fetal tissues, as it regulates oxidative imbalance in pregnant rat and alleviates histopathological and immunohistochemical changes. The findings indicate a need for further studies to assess the potential of boron in preventing or mitigating the effects of HFCS during pregnancy.
