No full textEffects of LLDPE/Clay Nanocomposite Films Including Bioactive Compounds on The Microbiological Quality of Fresh Kashar Cheese LLDPE/Kil Nanokompozit Filmler İçeren Biyoaktif Bileşiklerin Taze Kaşar Peynirinin Mikrobiyolojik Kalitesine Etkileri
No full textEmerging as a significant innovation in the food industry, active packaging extends shelf life, enhances safety, and maintains food quality by incorporating bioactive components like antimicrobial agents directly into packaging materials. In this context, polymer nanocomposites—particularly those reinforced with clay nanoparticles—have recently gained significant interest due to their enhanced functional properties. The cheese industry is one of the sectors with strong potential for applying such materials, as evidenced by recent developments in edible films for cheese. This study aimed to investigate the effects of active clay nanocomposite packaging films based on linear low-density polyethylene (LLDPE) containing eugenol (EUG) / thymol (THY) or carvacrol (CRV) loaded layered montmorillonite (MMT) or tubular halloysite (HNT) nanoclays. The study focused on their impact on the natural microbial load of kashar cheese, including total mesophilic aerobic bacteria (TMAB), total coliforms (TC), total lactic acid bacteria (LAB), and total yeast-mold (TYM), as well as on the presence/ growth of Listeria monocytogenes, Staphylococcus aureus, and Aspergillus niger, along with pH values, after storage at 10 °C for 30 days with analysis conducted every 10 days. The results showed that when prioritizing the packaging materials with the greatest impact on the microbial populations of kashar cheese, the order observed was as follows: THY-HNT for TMAB; EUG-MMT, CRV-HNT and THY-HNT for LAB; and CRV-HNT and THY-HNT for TYM. Moreover, S. aureus was not found in any of the kashar cheese samples. Furthermore, CRV-HNT and EUG-MMT films exhibited fungicidal properties throughout storage, leading to a decrease in mold spore counts, whereas THY-HNT films showed fungistatic effects. Additionally, CRV-HNT and THY-MMT packaging samples effectively limited growth of L. monocytogenes. As well, the pH values (5.15-5.52) of the cheese samples fluctuated during the storage period except for the control samples. Overall, the study showed that active nanocomposite films (ANFs) have the potential to extend shelf life, maintain safety and improve the overall quality of kashar cheese during storage
Promoting Engagement for Inclusion in Action: An Autoethnographic Journey of a Researcher-Preschool Teacher Experience
No full textSupporting children's engagement is essential for creating inclusive educational environments in early childhood. During early childhood, inclusive learning environments should provide all children with opportunities to engage in the learning process actively. This study aims to explore practices that encourage children’s engagement in such environments, to identify challenges encountered during this process, and to examine solutions to these challenges. A qualitative research method, specifically an autoethnographic approach, was employed. The researcher assumed dual roles as both educator and researcher. Data were collected through reflective journals maintained by the teacher-researcher and were subsequently analysed and interpreted using content analysis. As a result of this study, it was concluded that the environmental differentiation made to support children's engagement, along with the differentiation of the learning environment, content, and products, is effective. Additionally, it was observed that challenges arise from stakeholders, an inclusive perspective, and the resources of the school while supporting children's engagement. The researcher-teacher presents solutions to these challenges by offering training and consultations related to stakeholders, creating experiential opportunities linked to the inclusive process, and collaborating with institutions. Findings suggest that environmental arrangements, alongside the differentiation of learning processes, content, and products, significantly support children’s engagement
