    Lifestyle and eating behaviors during the COVID-19 pandemic: a cross-sectional study in Turkey
    (Bmc, 2025) Caner, Cengiz; Can, Aygul; Yuceer, Muhammed
    The COVID-19 pandemic significantly influenced individuals' lifestyles, eating behaviours, and food ordering purchasing practices, potentially altering overall dietary patterns. This study aimed to determine lifestyle and eating behavior among Turkish adults during COVID-19. A survey was conducted in 2023 in & Ccedil;anakkale using a Google Forms questionnaire to collect data from 365 Turkish individuals on sociodemographic factors, lifestyle, food purchasing habits, and dietary routines during the pandemic. Kruskal-Wallis tests were used to determine compare continuous variables across multiple groups. Findings revealed that 52.1% of participants experienced weight gain, 68.7% reported sleep disturbances, and exercise frequency declined during the pandemic. Conversely, smoking and alcohol consumption habits remained largely unchanged in about 60% of individuals. Employment status was found to significantly influence most lifestyle variables (p < 0.05). Regarding food shopping, 70.7% preferred chain supermarkets, while 46% engaged in online shopping, primarily for meat (47.7%) and snacks (27.4%). Online purchasing was significantly associated with age, education level, and employment (p < 0.05). A strong preference for homemade meals (94.8%) was also reported. In terms of dietary patterns, 58.1% maintained water intake, while 57.1% increased tea/coffee consumption. Daily meal frequency remained unchanged in 57.9%, yet notable increases were seen in the consumption of dairy/eggs (39.6%), fruits (38.4%), bread/pasta (34.1%), and meat (22.6%). About half reported greater intake of nutrient-dense foods, desserts, and snacks. This study reveals how COVID-19 affected dietary behaviors in T & uuml;rkiye, highlighting the need for targeted interventions and offering valuable insights to guide healthier lifestyle promotion and future health emergency planning.

    Ozone Pretreatment and Equilibrium-Modified Atmosphere Packaging as Elicitors to Enhance Shelf Stability and Nutraceutical Retention in Fresh Aronia (Aronia melanocarpa cv. Nero) Berries
    (Springer, 2025) Asik, Irem; Caner, Cengiz; Yuceer, Muhammed; Pala, Cigdem Uysal
    Ozone application is recognized for its eco-friendly, efficient, and cost-effective nature, making it a practical and prospective approach for increasing the storability of fresh produce. This study researched the synergistic impacts of ozone (5, 10, and 20 ppm) pretreatment and equilibrium-modified atmosphere packaging (EMAP) on the postharvest quality parameters of organic-labeled fresh aronia berries (Aronia melanocarpa cv. Nero) for 120 days at 4 degrees C. The key quality parameters are the composition of the gas in trays, weight loss, total soluble solids, pH, surface color, texture profile, spoilage rate, bioactive contents, and antioxidant properties. By the end of storage, the ozonated groups (10-20 ppm) showed significantly reduced spoilage rates of 6-8%, respectively, compared to 12-19% in the untreated control groups (P < 0.05). The combination of 5-10 ppm ozone pretreatment and sealing with microperforated polypropylene (PP) film was significantly effective in inhibiting fruit softening and retaining hardness at 379-375 gf, respectively, approximately a 16% reduction from initial values, which was significantly better than the 25% loss observed in the microperforated control (P < 0.05). Anthocyanin extractability significantly increased with 20 ppm ozone treatment (627 mg cyn 3-glu/100 g) when compared to untreated control groups (472 and 476 mg cyn 3-glu/100 g) on the initial day (P < 0.05). Among all the application groups, the 10 and 20 ppm ozone pretreatment groups demonstrated significant potential for preserving anthocyanins in aronia berries during storage. Additionally, ozone pretreatment positively influenced antioxidant properties based on CUPRAC values. These outcomes underline that the combination of ozone pretreatment and microperforated PP lid film packaging significantly enhances the cold storage stability and nutraceutical qualities of aronia fruits.
