    Kacar, Mihrican; Yangilar, Filiz; Yilmaz, Sevil Karahan; Yilmaz, Nazife

    Introduction: Eating disorders are closely related to mental status, and individuals with diabetes have a significantly increased risk of developing an eating disorder. Objective: This study aims to evaluate the possible association of cognitive restriction, uncontrolled eating, emotional eating factors, and eating disorders with depression in individuals with diabetes. Methods: A cross-sectional study was carried out on 132 patients who were diagnosed with diabetes between 2022 and 2024 in the Internal Medicine outpatient clinic of a university hospital in Türkiye. The Beck Depression Inventory (BDI) was used to assess the depression status of individuals, the Three-Factor Eating Questionnaire (TFEQ-R18) to measure eating habits, and the Night Eating Questionnaire (NEQ) to obtain information about night eating behavior. All anthropometric measurements were taken by the researcher. Results: It was determined that there was a 'mild depression' state in both the Type 1 diabetes patient group (14.10±8.26) and the Type 2 diabetes patient group (14.74±7.64). A linear, moderate, and significant correlation was found between BDI scores and NEQ scores in individuals with type 1 diabetes (r=0.547, p<0.001). In individuals with type 2 diabetes, an inverse, moderate, and significant correlation was found between BDI scores and cognitive restriction scores (r=-0.406, p=0.029). For the individuals in the two groups, statistically significant differences were found in the scores obtained from the BDI, NEQ, and TFEQ-R18 in terms of the history of mental illness and obesity, diabetic diet, and hypoglycemia (p<0.05). Conclusions: In this study, it has been shown that the effect of mental illness and obesity history on current eating behavior may be on night eating behavior, cognitive restriction, and uncontrolled eating. It is likely that compliance with the diabetic diet and prevention of hypoglycemia will be reflected in eating behavior and anthropometric measurements.

    Yangilar, Filiz; Erdaş, Zeynep Tuba

    This study aims to evaluate the potential of Kavılca fiber and astaxanthin to enhance yogurts’ nutritional content and antioxidant capacity, thereby contributing to developing a novel food product with significant health benefits. In this regard, the effects of different concentrations (1%, 1.5%, and 2%) of buckwheat fiber and astaxanthin on the quality properties of yogurt during a 21-day storage period were investigated. Enriching yogurts with buckwheat fiber and astaxanthin improved the viability, viscosity, water-holding capacity, and antioxidant activity of yogurt bacteria. The results indicated that the presence of astaxanthin had a positive impact on radical scavenging activity in samples, with CKA3 showing the highest radical scavenging activity (99.46%) after a storage period of 21 days while also exhibiting minimum serum separation among groups CKA3. Additionally, color parameters were significantly influenced by the addition of buckwheat fiber and astaxanthin (p < 0.05). The addition of buckwheat fiber and astaxanthin also positively affected the textural properties of yogurt samples during the storage period, and the most preferred sample was CKA1, along with the control samples.

    Production of Functional Kombucha Enhanced with Mormix, Mulberry Powder and Different Concentrations of Whey; [Farklı Konsantrasyonlarda Peynir Altı Suyu, Mormix ve Dut Tozu ile Zenginleştirilen Fonksiyonel Kombucha Üretimi]

    Bebek, Esra; Yangilar, Filiz

    In this study, the fortified fermented beverages with Kombucha culture (SCOBY) and different concentrations of whey (25%, 50%, 75%) by using mulberry powder to give natural sweetness with mormix rich in bioactive components during fermentation (1st, 5th, 7th, 9th, 11th and 13th days) microbiological, physicochemical and sensory properties were planned. This effort was to develop an innovative, functional, and immune-boosting product by combining Mormix, which is rich in bioactive compounds, and nutritionally valuable whey in the production of Kombucha tea. The lowest acetic acid bacteria count (6.87 log10 cfu mL-1) was found in the control sample, and the highest (8.07 log10 cfu mL-1) was found in the sample produced with green tea+75% whey+mormix+mulberry powder (KMP3). Lactobacillus spp. and Lactococcus spp. counts were determined to be the highest in the KMP3 sample. The effect of the samples on the mold counts developed in Kombucha beverages was statistically significant (p<0.01). Using green tea and different raw materials for Kombucha fermentation caused changes in dry matter, titration acidity, and pH values. The viscosity results were very significant during fermentation and adding different concentrations of whey and mormix+mulberry powder (p<0.01). It was determined that the L*, a*, b*, C, α°, and ∆E* color parameters of Kombucha enriched with whey and mormix+mulberry powder changed during fermentation. In fermented beverage samples made with Kombucha culture, an increase was observed in total phenolic content (981.33-1515.30 mg GAE g-1) and antioxidant capacity (DPPH 59.03-94.29%) during fermentation depending on the raw materials added. The sensory analysis showed that the most preferred sample was green tea+25% whey+mormix+mulberry powder (KMP1). Increasing the fermentation time caused an increase in acidity, and on the 13th day, KMP2 and KMP3 were the samples with the lowest taste scores. It has been obtained from the thesis findings that Kombucha can be evaluated as a new fermented beverage because raw materials such as whey and mormix used in its production provide strong antioxidant properties.

    Effects of Nettle (Urtica dioica) Extract on Versus Pathogenic Microorganisms in Yogurt Production; [Yoğurt Üretiminde Isırgan Otu (Urtica dioica) Ekstraktının Patojenik Mikroorganizmalara Karşı Etkileri]

    Gülhan, Barış; Yangilar, Filiz

    Contamination with pathogenic bacteria is the most common cause of foodborne illness and represents a public health problem worldwide. These pathogens can be controlled by adding extracts to fermented milk. In the present study, the effects of nettle extract on selected pathogenic bacteria in yogurt production were investigated. For this purpose, the antibacterial effectiveness of the extract additives in the presence of bacteria was examined and compared. Yoghurt samples, 24 different samples contaminated with 7 standard pathogen strains, were analyzed for chemical properties (pH and acidity) and antimicrobial activity after 1, 7, 14 and 21 days of storage at 4 °C. In particular, it was found that the decrease in pH and increase in acidity in the nettle extract samples after 21 days were significantly greater than in natural yogurt and yogurt samples containing nettle extract (0.5% and 1%, respectively) (p<0.05). Pathogens were reduced more significantly in samples treated with nettle extracts, which have antibacterial activity against pathogens. In particular, compared to natural yogurt, these samples showed significant antibacterial effects on the standard strains Streptococcus pneumoniae ATCC 45615, Klebsiella pneumoniae ATCC 70063 and Pseudomonas aeruginosa ATCC 27853 (p<0.01). Furthermore, in the samples containing nettle extract, the 1% concentration had synergistic effects on Streptococcus pneumoniae ATCC 45615, while the 0.5% concentration had synergistic effects on Klebsiella pneumoniae ATCC 70063 and Pseudomonas aeruginosa ATCC 27853. Overall, these results suggest that the nettle extract could be used as a natural preservative to improve the safety of yogurt and other dairy products.
