This study was conducted to evaluate the quality features, antioxidant capabilities, microbiological and sensory aspects of yogurt fortified with 2%, 5%, and 7% red dragon (RD) peel powder. The yogurt was formulated using the classical technology adapted to laboratory conditions. The results of the physicochemical properties showed significant differences in pH (4.73–4.36), acidity (0.18–0.16 g lactic acid/100 g), and ascorbic acid (1.17-1.34 mg/100 g) among different yogurt formulations (P<0.05). In addition, RD peel powder fortification showed increasing trends in crude fiber (1.53-3.34 g/100 g), ash (5.19-5.29 g/100 g), and moisture (76.70-80.19 g/100 g) content, respectively; while the reversed trend was observed for fat (3.48-2.36 g/100 g), and crude protein (4.49-4.07 g/100 g) contents, respectively. Furthermore, gradual progression of RD peel powder in fortified yogurt manifested an improvement of the overall antioxidant activity (1.30-1.57 µmol TE/mL). The analyses of the sensory properties demonstrated that yogurt with RD peel powder in proportions of 2% received the highest hedonic score for consumer approval. Moreover, no coliform was reported in any of the control and fortified yogurts. Therefore, it could be concluded that RD peel powder can be employed as a functional food constituent in yogurt with improved quality attributes and sensory properties compared to plain yogurt.

Cucurbitaceae family fruits, especially melons, offers significant quantities of minerals carotenoids and phenolic compounds, contributing to their antioxidant activity. However, seeds of these fruits are usually discarded as waste by products. In current study, seeds of watermelon (Citrullus lanatus) and muskmelon (Cucumis melo) were separated, dried, grounded and extracted, with 70% ethanol, to investigate total phenolic content (TPC), flavonoid content (TFC), carotenoid content (TC) content, and total antioxidant activity (TAA). Further, antimicrobial activities of these extracts were tested against selected bacterial and fungus strains. Results showed that extracts of both cucurbits presented significant amounts of phytochemicals, with higher quantities presented by watermelon seeds. In watermelon seeds, TPC were found 156.50 mg/GAE 100 g, TFC 56.78 mg CE/100 g, TC 36.65 mg/100 g, and TAA 71%, and these amounts were significantly higher than those found in muskmelon seeds. Antimicrobial study results showed that extracts of both seeds exhibited significant zone of inhibitions against three bacterial and three fungal species, and these values were very comparable to the reference antimicrobial drug used, Ciprofloxacin. Findings of current research work provided significant grounds for presence of phytochemical bioactives in two melon fruits seeds, providing the basis for extraction and utilization of these bioactives, through processing and fortification different pharma foods.

Safe meat production is an important aspect to avoid human health hazards. The use of probiotics in poultry is an important tool to produce safe meat among several established biotechnological approaches. In this experiment, we studied the effects of probiotics for producing safe Japanese quail meat. 150 Japanese quail chicks were reared for a period of six weeks using various doses of probiotics (0, 0.5, 1, 1.5, and 2g per litre of water). The chicks were randomly distributed into five treatment groups with three replications each. The number of birds in each replication was 10. After rearing six weeks, significantly high body weight was found at probiotic concentrations of 1, 1.5, and 2g per litre of water. The feed intake in various treatments did not differ significantly, but comparatively better feed conversion ratios were observed at probiotic treatments. Water quality was not significantly differed as a result of addition of probiotics to the water. The reason for this better growth performance is probably due to the multiple benefits of probiotics in poultry. Probiotics could have maintained gut health with better nutrient utilization and availability that might have been led to higher body weight gain in the quail. In future experiments, challenging the birds with diseases or comparing probiotics with antibiotic growth promoters is required to ensure the efficiency of probiotics.

Traditional milk desserts are one of the most essential dessert groups that Turkish society consumes. Due to foaming activity, it was aimed to investigate the feasibility of the ohmic heating system to produce a semolina dessert with milk. Hence, an ohmic heating treatment was used to heat the milk, semolina, and sugar mix from 20°C to 100°C using three different voltage gradients (15, 17.5, and 20 V/cm) and then boil for two minutes. It was found that the current value escalated from 20°C to approximately 86°C but decreased after 86°C due to foaming. Since the total consumed energy during the ohmic cooking treatment was inversely proportional to the treatment time, the total consumed energy values decreased based on the rising voltage gradient. As a result, the feasibility of the ohmic heating treatment for making a traditional semolina dessert with milk was determined in this study.

Quercetin (QU) is a flavonoid found in different fruits and vegetables. Studies report that QU may have positive effects on neurological diseases. However, the effect of QU on 4-aminopyridine (4-AP)-induced neurodegeneration in neuronal cells is still not fully elucidated. In this study, the effects of QU on 4-AP-induced hippocampal neuron damage in vitro and the possible role of oxidative stress and endoplasmic reticulum stress in this effect were investigated. The study was carried out using the HT-22 hippocampal neuronal cell line. The effect of pre-treatment with QU on cell viability after 4-AP-induced neuronal damage was determined by the XTT test. Cells were evaluated histopathologically for apoptotic nuclear change (ANC) using DAPI staining. The effects of QU on oxidative stress (total oxidant state (TOS) and total antioxidant status (TAS)) occurring after neuronal damage were evaluated with colorimetric commercial kits and endoplasmic reticulum stress markers (activating transcription factor 4 (ATF-4) and C/EBP homologous protein). (CHOP) was measured with the ELISA kits. While the cell viability rate decreased in the cells treated with 4-AP, it was determined that pre-treatment with QU reversed this situation. In terms of histopathology, treatment with 4-AP increased the number of ANC, while QU pre-treatment reduced it. In addition, in terms of biochemical evaluations, TOS, ATF-4, and CHOP increased in neuronal cells after 4-AP, and QU was determined to suppress this increase. In addition, QU normalized the decreased TAS levels following the 4-AP application. As a result, in the HT-22 cell line, it was found that QU treatment had a neuroprotective effect by suppressing oxidative stress and endoplasmic reticulum stress in 4-AP-induced neuronal damage.

Lipoxygenases (LOX) gene family is a type of nonheme iron-containing dioxygenases, which has a very important aspect in plant development and fruit quality. LOX gene, which is responsible for lipid oxidation, the main role for the biosynthesis pathway of unsaturated fatty acids. Although some studies have investigated the LOX gene family in several species including arabidopsis, soybean, peanut and apple, there is no information from Pistachio; and the phylogeny of this gene family in the Pistacia genus is still not determined. In this study, Arabidopsis thaliana LOX1 gene (NCBI Reference Sequence: NM_104376.3) was selected and used as a query sequence for performing a BLASTN search. Among all sequence query which was found by NCBI platform, 9 sequences were selected for further analysis. Phylogenetic tree of full-length LOX gene sequences from the Pistacia genus was constructed using the Maximum Likelihood method with MEGA software. By using phylogenic analysis, we identified variations in gene structure and revealed the phylogenetic evolutionary relationship of this gene family. Additionally, this may serve as a reference value for assessing the genetic relationships among various LOX genes in Pistacia genus species. This variations provides us the possibility the design the primer to achieve us to find the exact LOX gene in Pistacia genus and future research on the evolutionary history and transgenic research on LOX genes.

In the current study, the essential oil of Thymus citriodorus (Pers.) Schreb (Lamiaceae) was evaluated for its ability to control adults of two significant pests of stored products, Sitophilus granarius (Linnaeus, 1758) (Coleoptera: Dryophthoridae) and Tribolium castaneum (Herbst, 1797) (Coleoptera: Tenebrionidae), under laboratory conditions. Using a microapplicator, test insects were exposed to 0.025, 0.05, 0.1 and 0.15 µl/insect concentrations of plant essential oil in order to assess contact toxicity. At 24, 48, 72, and 96 hours following applications, deaths were noted. The experiment revealed that, depending on the insects and dosages, the essential oil showed varying degrees of contact activity. The essential oil of T. citriodorus generally had low effect on adult T. castaneum, with the greatest effect was 15.32% at 0.15 µl/insect dose after 96 hours. Adults of S. granarius showed greater sensitivity to the essential oil of T. citriodorus. After 48 hours, doses of 0.1 and 0.15 µl/insect concentrations of the essential oil resulted in over 95% of S. granarius adult mortality. The findings of the study indicate that T. citriodorus essential oil has the potential to be used in the control of S. granarius.

A field experiment was conducted at the Agronomy farm of Nepal Agricultural Research Council (NARC), Khumaltar, Lalitpur to evaluate the effect of sowing dates and seed rates on yield and yield attributes of wheat. The experiment was laid in a split-plot design with three replications treated with 4 sowing dates as the main plot factor (12th Nov, 27th Nov, 12th Dec, and 27th Dec) and 4 seed rates as subplot factor (100 kg ha-1, 120 kg ha-1, 140 kg ha-1 and 160 kg ha-1). Results revealed that the leaf area index was significantly affected by sowing dates and was comparatively superior in 2nd sowing date (27th Nov) wheat. Similarly, in the case of seed rates, the leaf area index was influenced significantly and was recorded to be increasing with an increase in seed rates. Phenological parameters like days to 50% heading, flowering, and maturity were observed maximum (116, 123, and 179 days, respectively) in early sown wheat and reduced with the subsequent delay in sowing. Maximum values of yield and yield attributes like effective tillers per meter square (635.6), spike length (9.56 cm), grains per spike (41.49), grain yield (7.59 Mt ha-1), and straw yield (9.58 Mt ha-1) were observed in the wheat sown in 2nd date (on 27th Nov) which differed significantly to wheat sown on other dates. Seed rates had no significant influence on grain yield and yield attributes. Thousand-grain weight was found maximum (46.26 g) in early sown wheat (on 12th Nov sown wheat, reduced with the subsequent delay in sowing, and the harvest index was observed as maximum (0.51) under December 27 sown wheat. Though the yield and its attributes were not influenced significantly by seed rate, the maximum yield (6.18 Mt ha-1) was observed in wheat sown at the rate of 120 kg ha-1. Considering seed yield and its parameters, 2nd date of sowing wheat (27th Nov) and seed rate of 100 kg ha-1 could be the best option to uplift the productivity of wheat in rainfed lowland conditions of Lalitpur, Nepal.

Erdi Eren | Fulya Sarper
Functional foods are the name given to food groups that, when consumed, have beneficial effects such as promoting and maintaining metabolic health and preventing diseases, rather than just meeting nutritional needs. Rock samphire (Crithmum maritimum L.), is a plant that grows naturally in the Mediterranean and Aegean regions of Turkey and on the coasts of Cyprus, has been consumed in these regions for many years. The consumption of the rock samphire, which draws attention with its high iodine and bioactive component content, has been limited to the regions where it grows. In this study, the local consumption habits, recipes of the rock samphire plant and the awareness of its functional properties were determined. In the study, six different recipes were obtained from the local people. Traditional products prepared according to the recipes were photographed by the authors. In addition, twenty local people were interviewed and it was determined that consumers were informed about the functional properties of the rock samphire and that these properties motivated consumers to consume the plant. As a result of the study, it was concluded that the integration of locally-consumed rock samphire into the daily diets by introducing them into non-regional cuisines would contribute positively to the general public health and the economy of the region.

2023
Bilal Kargı | Hrabrin Bachev
The farm is an abstract category in Economic theory for describing agents managing farming activity, while the real governing structures are farms of different juridical types – physical persons, sole traders, cooperatives, ago=companies, etc. Most of the time, farm’s competitiveness is inadequately assessed through technical and accountancy efficiency, factors’ productivity, profitability, market shares, etc. because critical governance aspects are ignored. This article incorporates the interdisciplinary New Institutional Economics assumptions and principles and tries to give new insights on the real competitiveness of economic organizations in modern agriculture. It suggests a holistic framework for assessing farm’ competitiveness taking into account economic, financial, and governance efficiency, and evaluates absolute and comparative competitiveness of governing structures of Bulgarian farming. The novel assessment system includes four pillars, four criteria, 17 particular, and 5 integral indicators. The first-in-kind evaluation, based on survey data, found that the competitiveness of Bulgarian farms is good. The competitiveness of cooperatives is highest, followed by corporations and associations, sole traders, and physical persons. Critical for competitive positions of farms are: low productivity, income, financial security, and adaptability to natural environment, where public support and farms’ management strategies should be directed. Large shares of the country’s farms have low competitiveness, and if measures are not taken to improve management, restructuring, state support, etc., many farms will cease to exist in the near future. In some cases, other characteristics of governing structures like size, specialization, market orientation, and ecological location, are critical for determining competitiveness level. The suggested and successfully tested framework for assessing the competitiveness of farms should be further improved and applied more widely and periodically in the country and internationally. The precision and representativeness of the information used should also be improved by increasing the number of surveyed farms and their important characteristics. The later requires close cooperation with producer organizations, national agricultural advisory service, and other interested parties as well as extending and improving the system for collecting agro-statistical information in the country and the EU.
