Yangılar, Filiz; Gerek, Merve Dilara
The study aimed to evaluate the potential of creating a functional beverage by enriching Anthriscus sylvestris (L.) kombucha production with guava peel and pulp, showcasing the variety and richness of the product formulations. This was done due to kombucha being a fermented beverage rich in various bioactive compounds that have significant effects on health and the possibility of enhancing product diversity through different formulations. Thus, the kombucha tea was physicochemical, phytochemical, antioxidant activity, and sensory evaluation during the 15-day fermentation period. The increased acetic acid bacteria and yeast count indicates that Anthriscus sylvestris is a viable substrate for the proliferation of Kombucha symbiotic microbes. Adding guava peel and rosemary oil to kombucha significantly increased its total phenolic, flavonoid, and vitamin C content (P<0.05). Anthriscus sylvestris-guava kombucha has antibacterial properties (zones of inhibition of 18.32 and 17.31 mm against Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 25922, respectively). Moreover, it also provided an inhibitory effect on α-glucosidase and α-amylase, enzymes associated with diabetes. The DPPH, ABTS*+, FRAP, CUPRAC, and ORAC capacities were found to be 66.89-78.90%, 70.83-97.25%, 367-723.15 µmol Trolox/mL, 381.40-460.45 µmol Trolox/mL, and 486.50-737.50 µmol Trolox/mL, respectively. Anthriscus sylvestris kombucha has well-balanced and pleasant sensory properties. These findings indicate that preparing Anthriscus sylvestris kombucha tea with guava may have health effects and that further research is needed to determine potential health benefits.

Objective: Food additives are widely used in industry to improve the appearance, quality and safety of food during processing, storage and packaging. The sunflower (Helianthus annuus L.) is an important agricultural product that is cultivated worldwide for seeds. Its seeds are one of the largest sources of vegetable oil. In this study, the biological activity of sunflower seeds as well as various plant parts, which are agricultural by-products and mostly treated as waste, was tested and their potential for use as a food additive was determined. Material and Method: The antiproliferative effect of six different plant parts (seeds, ray florets, disc florets, leaves, stems and receptacle) of four sunflower varieties (DERAY, SY GRANIT, P64 LP 130, TR 2242 CL) against the healthy cell line L929 was investigated using the MTT method and the concentration range that can be safely used was determined. The antioxidant capacity was determined using the DPPH, TEAC and CUPRAC methods. Inhibition of the enzyme tyrosinase was investigated to prevent enzymatic browning of food. Result and Discussion: It was found that even at concentration of 400 and 800 µg/ml, safe use is possible. In all methods, disc floret and ray floret showed a strong antioxidant effect. In the DPPH free radical scavenging effect of the ray floret of the TR 2242 CL showed the highest value with 101.40 mg gallic acid/g extract. Disc and ray floret showed strong inhibition of the tyrosinase enzyme in all varieties. The enzyme inhibition of methanol extracts of TR 2242 CL ray and disc floret was found to be 60.42 and 151.25 mg KAE/g extract, respectively. The lack of cytotoxicity against healthy cells, the high antioxidant capacity and the strong anti-browning activity suggest that sunflower agro-food byproducts may be a new, non-toxic, cost-effective and recyclable source to be used in the food industry instead of food additives that have negative side effects on health.

In this study, the insecticidal activity of essential oils (EOs) of three Achillea species of Türkiye [Achillea aleppica subsp. zederbaueri (AAZ), A. arabica (AA) and A. santolinoides subsp. wilhelmsii (ASW)] on the Rhyzopertha dominica were determined. GC-MS analysis identified camphor (41.0%) and eucalyptol (21.3%) in AA; camphor (41.6%) in AAZ; and borneol (21.1%) in ASW as major compounds. Insecticidal activity of EOs against R. dominica was found to be both dose and time-dependent, with higher concentrations and longer exposure leading to increased mortality. Notably, all EOs caused 99±1% mortality at 20% (v/v) within 24 hours (p < 0.05), while AAZ EOs exhibited the strongest effects even at 10% (v/v) concentration over extended exposure periods with 67.6±2.1% mortality. Although EOs are known to induce toxicity in insects, the molecular-level expression of key detoxification genes (GST, CYP450, and CarE) was analyzed for the first time in R. dominica exposed to EOs using qRT-PCR. qRT-PCR analyses revealed that the exposure to EOs significantly upregulated detoxification-related genes in R. dominica. Notably, 24 hours of exposure to AA EOs caused a 4.89±0.35-fold increase in the GST gene expression. Partial least squares (PLS) regression showed that the strong association between biological effects and chemical profile of EOs. The findings demonstrate that Achillea EOs act via direct toxicity and detoxification induction, highlighting their potential as eco-friendly biopesticides. However, high concentration requirements may restrict application; thus, future studies should develop synergistic formulations and nano-encapsulation to enhance efficacy and stability.

Industrialization-driven heavy metal contamination is a growing concern, as residues are increasingly found in foods and tap water due to soil absorption by plants. This study aimed to assess the amount of heavy metals including arsenic, cadmium, aluminum, and copper in widely produced domestic rice cultivars in Türkiye, and to evaluate the effect of pretreatments and domestic cooking on the concentration of heavy metals. Six different rice cultivars were analyzed using inductively coupled plasma-mass spectrometry to determine the levels of heavy metals. Among these six cultivars, the highest heavy metal contamination and also the most consumed was selected to evaluate the effect of soaking processes accompanied by acetic acid (0.25, 0.50, 0.75, and 1%) and salt (1%) at different soaking times (2, 4, 8, and 12 h) and domestic cooking. The concentrations of heavy metals in the primary rice cultivar with the highest contamination were 64.9, 1.3, 2476.7 and 3185.2 μgkg−1 dry weight, respectively. The results showed that soaking in salt (1%) and acetic acid (1%) before cooking was the most effective treatment for removing heavy metals (As = 57.8%, Cd = 100%, Al = 98%, and Cu = 85.7%) at a soaking time of 12 h.

Çebi, Kadir; Yangılar, Filiz
Nowadays, individuals with cow's milk allergy have shown greater interest in plant-based (PB) milk alternatives. This study addresses this issue by producing cow's milk yogurt, lupin-based yogurt, and a hybrid of cow's and PB milk yogurt. In addition, a safe food formulation was developed by incorporating probiotic bacteria and sandalwood oil into these yogurt types. Statistical analysis revealed that the type of milk significantly influenced the physicochemical properties of the yogurts (p < 0.05). The highest mean syneresis (6.78 mL/25 g) was observed in the cow's milk yogurt (C2), whereas the combination of dairy and lupin-based yogurt (CL2) exhibited the greatest water-holding capacity (WHC) (3933 cP). The total phenolic content (TPC) across all yogurt samples ranged from 6.67 to 19.58 mg GAE/g, with the lupin-based yogurts showing the highest values. Specifically, the lupin-based yogurt (L4) displayed the highest antioxidant activity of 34.14%, compared to 9.49% in dairy yogurt (C1). Throughout the storage period, Lactobacillus acidophilus counts remained above 8.45 log cfu/mL in dairy yogurt and 7.78 log cfu/g in lupin-based yogurt. The firmness, cohesiveness, and viscosity index values of lupin-based yogurts were higher than those of the other yogurt types. Organoleptic analysis indicated that PB yogurts were similarly well-received as dairy products.

Selbeş, Esra Bostancı; Şahin, Özlem; Vural, Halil
This study investigated the effects of melocan leaf extract (ME), obtained by supercritical carbon dioxide (Sc-CO2) extraction, on the quality characteristics of beef meatballs during cold storage (0, 3, 6, and 9 days). ME was incorporated at three levels (0.1 %, 0.5 %, 1 % – marked as ME0.1, ME0.5 and ME1). The results showed that the use of ME significantly delayed lipid oxidation in beef meatballs during cold storage (p < 0.05). While the thiobarbituric acid reactive substances (TBARS) value reached 2.46 mg·kg-1 malonaldehyde (MA) in the control group, the meatballs with no ME content, the TBARS values of ME0.1, ME0.5 and ME1 reached 1.39, 0.92, and 1.00 mg·kg-1 MA, respectively. As the extract content increased, the lightness L* and redness a* values of the meatballs decreased (p < 0.05). ME effectively inhibited lipid oxidation and increased the antioxidant capacity in beef meatballs, without significantly affecting total mesophilic aerobic bacteria and total mould and yeast counts (p > 0.05). In terms of sensory evaluation scores, the group containing 0.1 % ME was the closest to the control group, and since it considerably prevented lipid oxidation even at this level, the use of 0.1 % ME in beef meatballs is recommended.

Can, Esra İrem; Çebi, Kadir
The nutritional adjustment of food products has gained popularity in recent years as consumer interest in healthy eating has increased. Cake is a widely consumed cereal-based product containing such key nutrients as carbohydrate, fat, protein, fiber, vitamins, and minerals. In the present study, crust and crumb color, specific volume, microstructure, antimicrobial activity, total phenolic content, antioxidant activity, and sensory analyses were evaluated in four cake groups: a control cake (IT0) and cakes supplemented with 1% (IT1), 3% (IT2), and 5% (IT3) nettle seed powder. The addition of nettle seed powder to the cakes significantly reduced the crust (L*, a* and b*) and crumb color (L* and b*) parameters, with darker coloration due to the natural pigments and phenolic compounds in nettle seeds. The total phenolic content (TPC) in the cake samples ranged from 3.58 to 4.80 mg gallic acid equivalent (GAE)/g, and addition of nettle seed powder significantly increased TPC, which was attributed to the phenolic-rich composition of nettle seeds. The elimination rates of superoxide (O2•–), hydroxyl (OH•), nitric oxide (NO•), 2,2-diphenyl-1-picrylhydrazyl (DPPH), and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) radicals, as well as the iron-reducing potential, increased as the nettle seed concentration was increased, confirming the strong antioxidant capacity of nettle bioactives. The majority of sensory analysis parameters were found to be statistically significant. Although enrichment improved chemical and functional quality, it led to lower sensory scores, particularly in the 5% (IT3) group, which can be attributed to the darker color and distinct herbal flavor from the nettle seed powder. Considering all parameters, the 3% nettle seed cake (IT2) had the most balanced profile, successfully combining enhanced nutritional and antioxidant properties with acceptable sensory characteristics. IT2 can thus be recommended as the optimal, functional and most innovative cake formulation among the tested concentrations.

In this study, bacteriophages specific to Pseudomonas aeruginosa strains were isolated from wastewaters, and their potential to be used as a bioprotective in chicken meat was investigated. Then, among the 35 isolated bacteriophages, two phages (vB_PaeS-K10 and vB_PaeS-K13) with a wide host cell range and strong clear plaque formation were selected and their morphological, physical–chemical, and genetic properties and their inhibitory effects against the host cell in chicken meat were determined. As a consequence of the examination by TEM (transmission electron microscopy), vB_PaeS-K10 and vB_PaeS-K13 phages belong to the family Siphoviridae of the order Caudovirales. The genome size, multiplicity of infection value, latent period, burst time, and burst size of vB_PaeS-K10 phage were 54.20 kb, 10, 75 min, 30 min, and 34.86, respectively, whereas those of vB_PaeS-K13 phage were 44.06 kb, 0.01, 20 min, 35 min, and 35.95. Both of them were resistant to high temperature and entirely active between pH 3 and 12, and the rate of absorption of the phages against their host cells increased with Ca2+ ions. Lytic activity test revealed that both phages reduced host cell density in LB broth at 4 °C and 37 °C. Moreover, vB_PaeS-K10 and vB_PaeS-K13 phages lethally infect P. aeruginosa at 4 °C in chicken meat, and this situation is the evidence of their potential to be utilized as bioprotective in chicken meat.

Bulut, Hüseyin; Yildirim, Fatih Serdar
Plants, due to their fixed locations, are susceptible targets to environmental stress. Among these stresses, heavy metal stress has increased since the Industrial Revolution. Thermal power plants that utilize fossil fuels play a significant role in the release of heavy metals into the environment. This study investigates the role of air currents in the transport of fly ash from thermal power plants and its genotoxic effects on wheat using molecular methods. The mobility of retrotransposons affecting genomic stability was assessed through IRAP (Inter-Retrotransposon Amplified Polymorphism) analysis. The IRAP analysis results indicate a polymorphism rate of 54.6% in wheat seedlings located 1 km northwest of the thermal power plant. The lowest polymorphism rate, 29.66%, was observed in wheat samples 10 km east of the plant. Physical damage in the nucleus caused by heavy metals was evaluated using the comet assay, which measures tail length, tail DNA percentage, and tail moment. Similar to the IRAP analysis, significant damage was observed in the northwest, southwest, and west directions across all three parameters. The findings of this study underscore the impact of heavy metal pollution and emphasize the importance of air currents in the dispersion of these pollutants.

This study’s objective is to explore the influence of particle size on the characteristics and functionalities of baby corn powder. In food product development and application, particle properties are crucial. Sieve analysis using a series of standardized sieves determined the particle size distribution, ranging from >500 µm to 53 µm. The particles exhibited stability, with an average size of 208.8 nm, a polydispersity index of 0.133, and a zeta potential of –20 mV. Bulk density (BD) and true density (TD) showed an inverse relationship with particle size, with BD ranging from 0.552 to 0.238 gcm–3 for particle sizes >500 to 53 µm, respectively. The Carr index and Hausner ratio indicated better flowability in particles up to 300 µm. Principal component analysis revealed that the first principal component accounted for 90.1% of the variance, highlighting phenolic content as a key factor. Parameters clustered into four groups: Group I (emulsion stability, fiber %, moisture %, and fat %), Group II (BD, foaming stability (FS), carbohydrate %, and oil absorption capacity (OAC)), Group III (protein %, ferric reducing antioxidant power, flavonoid content, and total soluble sugars), and Group IV (iron, calcium, phenol, magnesium, phosphorus, and 2-diphenyl-1-picrylhydrazyl activity). Correlation analysis showed strong positive relationships between antioxidant activities and phenolic (+0.99) and flavonoid content (+0.93), with negative correlations to carbohydrates (–0.89). Additionally, FS positively correlated with OAC (+0.78), while BD and TD correlated positively with the angle of repose (+ 0.97) and negatively with the Carr index and Hausner ratio (–0.98). Clustering identified three distinct particle size groups: Group I (>500 µm, 500 µm, and 420 µm), Group II (300 µm), and Group III (150 µm, 75 µm, and 53 µm), with Group II showing unique biochemical and technofunctional properties.

Salinity stress is a major environmental factor that poses a significant constraint to plant growth, threatening agricultural productivity and sustainability. This study investigated the potential of halotolerant bacteria, isolated from the rhizosphere of wild halotolerant plants in Turkey’s Salt Lake basin, to enhance salt stress tolerance in maize (Zea mays L.). The rhizospheres of 17 different wild halotolerant plants were selected for bacterial isolation, resulting in the identification of 22 halotolerant bacteria using 16S rRNA sequence analysis. Among these, 19 isolates were found to possess positive activity for 1-aminocyclopropane-1-carboxylate (ACC) deaminase and nitrogen fixation. When the maize seeds inoculated with these 19 isolates were grown under normal conditions, four isolates‒TG-4 (Halomonas arcis), TG-8 (Marinococcus tarigensis), TG-12 (Halobacillus dabanensis), and TG-20 (Halomonas eurihalina)–significantly stimulated seedling growth and development. To evaluate the effect of these four isolates on salt tolerance, inoculated seeds were grown under various salt conditions (0.0, 75, 150, and 250 mM NaCl). The responses of plants to salt stress were analyzed by evaluating growth parameters, membrane damage, photosynthetic pigment and proline content, reactive oxygen species and lipid peroxidation levels, and antioxidant enzyme activities. According to the parameters, the results indicated that TG-4, TG-8, and TG-12, in particular, have the potential to function as plant growth-promoting rhizobacteria and effectively enhance salt stress tolerance in the maize seedlings. Overall, this research highlights the potential of halotolerant bacteria to improve salt stress tolerance in maize plants through multifaceted mechanisms, offering valuable insights for sustainable agriculture in saline environments.

Objective: To assess maternal readiness for weaning and examine the socio-demographic and behavioral factors influencing weaning decisions. Method: A cross-sectional study was conducted at three Family Health Centers located in a provincial center between October 2024 and January 2025. The study included 202 breastfeeding mothers. Data were collected through face-to-face interviews using a sociodemographic questionnaire and the validated Readiness for Weaning Scale. Statistical analyses included t-tests, ANOVA, chi-square tests, and logistic regression. Results: Mothers with higher education had significantly higher scale scores than those with lower education. Breastfeeding education was associated with increased weaning readiness. Planned pregnancy and maternal perception of milk sufficiency were positively correlated with higher scale scores. Smoking was associated with lower readiness. Logistic regression indicated that maternal perception of milk sufficiency significantly predicted weaning consideration, while lower education levels were associated with reliance on traditional weaning methods. Traditional weaning methods referenced in this study include culturally ingrained practices such as abrupt cessation, use of herbal substances, or application of unpleasant tastes to the breast. Conclusion: Maternal education, psychological preparedness, and professional support play key roles in structured weaning. Targeted interventions are needed to enhance maternal confidence and informed decision-making in infant feeding transitions. Limitations of the study include its cross-sectional design, which prevents causal inference, and the reliance on self-reported data, which may be subject to recall or social desirability bias.

Artificial neural networks (ANNs), support vector regression (SVR) and CatBoost regression (CBR) machine learning methods have been combined with the honey badger optimization algorithm (HBA) and metaheuristic optimization algorithm to accurately and reliably predict lake water level (LWL), which is of great importance for the management and planning of water resources. In this study, meteorological and hydrological parameters, including temperature (T), precipitation (P), date (D), surface soil moisture (SSW), root zone moisture (RZW) and water level (WL), were employed as input data for predicting the LWL of Urmia Lake. The input data were employed to develop six different prediction scenarios. This study not only examined the impact of meteorological and hydrological parameters on LWL prediction but also compared the performance of individual models and hybrid models. The Akaike information criterion (AIC) index was used to ascertain the optimal machine learning model and to evaluate the six prediction scenarios. The results of the study indicate that, according to the AIC index, the data regarding the water level (WL) were significant in the prediction models. However, it should be noted that satisfactory results could also be obtained without using the WL data in certain scenarios. In scenario 4 (input data: D, T, P, SSW, RZW), where the WL variable was not included, the HBA-CBR hybrid model was the best model with the lowest AIC value (Train: -63,735, Test:-4693). In prediction scenario 6 (input data: D, T, P, SSW, RZW, WL), which included the WL data, the HBA-SVR hybrid model demonstrated high performance with the lowest AIC value (Train: -102,358, Test:-27,233). Accordingly, it was recommended to use lagged WL values as input in WL prediction because the prediction accuracy of the models significantly improved. Furthermore, hybrid models were found to perform better than individual models due to their more consistent results.
