The goal of this study is to identify and manage fungal contaminants present in mushrooms during postharvest conditions. A total of 23 fungi were isolated as contaminants from the samples of Agaricus bisporus collected from three major vegetable markets in Kathmandu city, Nepal. Aspergillus niger, Aspergillus flavus, and Rhizopus stolonifer were found to be the most frequent fungal contaminants. These were treated with various concentrations of essential oils (EOs) of Cinnamomum tamala, Mentha spicata, Zanthoxylum armatum, and Eucalyptus citriodora using poisoned food technique. Significant (p<0.05) inhibition of mycelial growth and spore germination was found in all testedfungi by all EOs. A strong inhibitory action of M. spicata oil was recorded against A. flavus and R. stolonifer while, A. niger was best controlled by C. tamala oil at the concentration of 20 µl/ml. These results suggest that EOs of three tested plants could be a good alternative to control fungal contaminants and extend the shelf life of Agaricus bisporus in postharvest conditions.","PeriodicalId":13814,"journal":{"name":"International Journal of Agriculture, Environment and Food Sciences","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136272368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Effectively managing and accurately defining these risks is paramount. Risk assessment begins by assigning scores to identify existing workplace hazards, assess the likelihood of potential risks, determine the level of urgency, and determine the necessary precautions. It is a continuous cycle of implementation, monitoring and review. The aim of this study is the identification of existing or potential hazards and risks in a dairy products factory in Iğdır province, Turkey. The Fine Kinney risk assessment methodology was applied, and the results provided recommendations for mitigating identified risks based on relevant regulations. Initially, brainstorming sessions were held with relevant employees and managers to gain a general overview of the health and safety culture in the work environment. In addition, observational analysis and weekly checklists were used for assessment purposes. When examining the current status and operational procedures of the company in detail, various hazards containing risks that require immediate precautions have been identified. Electric shock (RS: 1440), injuries related to electricity (RS: 720), explosion (RS: 540), and risks associated with poisoning or drowning (RS: 720) have been determined to be present. It has been concluded that most of the environmental risks in the facility arise from factors such as defective or outdated equipment, lack of ergonomic workstations, inadequate training, and insufficient supervision.","PeriodicalId":13814,"journal":{"name":"International Journal of Agriculture, Environment and Food Sciences","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136277724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phosphine fumigation is a widely used method to control pests in stored products, including hazelnut kernels. This study aimed to determine the optimal exposure time for phosphine fumigation for management of stored product pests in hazelnuts. Four treatments with different exposure times (3, 4, 5, and 6 days) were conducted using various development stages of Oryzaephilus surinamensis (L.) (Coleoptera: Silvanidae), Tribolium confusum Jaqcquelin du Val, (Coleoptera: Tenebrionidae), Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), Ephestia kuehniella Zeller (Lepidoptera: Pyralidae), and Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae) together with the control group. The trials were conducted in a commercial chamber of a hazelnut processing facility. The insects were placed in plastic containers within jute sacks filled with hazelnuts, fumigations were done under gas-proof sheet and the survival rate was assessed after treatments. The results showed that a 3-day exposure period was sufficient to fully eradicate the pupal and adult stages of O. surinamensis. For T. castaneum, 100% mortality was achieved in both larvae and adults from 3 days of exposure, but the pupal stage required at least 5 days. For T. confusum, all larvae and adults died in all exposure periods, but the pupal stage required at least 4 days. In the case of the moth species, a 100% mortality rate was achieved in the larval and pupal stages of both E. kuehniella and P. interpunctella at all exposure periods. The mortality rate of E. kuehniella eggs was 99% after 3 and 4 days of exposure, and a fumigation period of 5 days was required to control the entire population. However, only 67% of P. interpunctella eggs were controlled after 3 days of exposure. The time and stage factors were found to be significant in the egg stage of P. interpunctella. The results suggest that a 5-day exposure period is the most effective for controlling tested stored product pests in hazelnuts.","PeriodicalId":13814,"journal":{"name":"International Journal of Agriculture, Environment and Food Sciences","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136277368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the rapid growth of tourism has brought about both positive economic impacts and negative environmental consequences. This research delves into the environmental effects of tourism activities through the lens of sustainable tourism. Focusing on Niksar Çamiçi Plateau, a transition zone between Central Anatolia and the Black Sea Region, situated at an altitude of 1350 meters, the study aims to identify the specific environmental impacts resulting from tourism activities in this unique location. The research adopts participant observation and semi-structured interviews as data collection methods, enabling a comprehensive understanding of tourists’ and locals’ behaviors and practices concerning the environment. The findings highlight the pressing issues of unplanned development, urban sprawl, migration, and environmental pollution in regions experiencing concentrated tourism activities. In response to these challenges, the study proposes a set of sustainable tourism solutions to mitigate environmental degradation. Recommendations include promoting responsible tourism practices, reducing the carbon footprint, promoting environmentally friendly accommodation and transportation, and implementing effective waste management strategies. Additionally, raising awareness among tourists and local communities about the importance of preserving natural resources and cultural heritage emerges as a crucial approach. This study contributes to the growing body of knowledge on sustainable tourism by providing valuable insights into the complex relationship between tourism and the environment, particularly in Niksar Çamiçi Plateau. By advocating for sustainable practices, the research aims to strike a balance between economic growth and environmental conservation, ensuring a harmonious coexistence between tourism and the ecosystem.","PeriodicalId":13814,"journal":{"name":"International Journal of Agriculture, Environment and Food Sciences","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136277771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this aim, five white grained bread wheat cultivars such as Altınöz, Candaş, Gökkan, Şahika, and Yakamoz were used as material. And, tarhana samples were dried under open air, airflow oven and vacuum. The study was conducted with three replications according to the split plot design in random plots. All quality traits showed statistically significant variations for the bread wheat cultivars (C), drying techniques (DT), and DT×C interactions. Thus, airflow oven showed the highest values among the drying techniques for the contents of ash (8.5892%), total titration acidity (27.433%) and salt (6.842%). On the other hand, open air drying technique presented the highest values for moisture (14.556%), pH (4.349) and the density of lactic acid bacteria (LAB) (1.4×104 CFU g-1 for M17 agar, 2.4×104 CFU g-1 for MRS agar. Also, Gökkan cv had the highest percents for all quality traits except LAB density. These findings showed that the most suitable bread wheat cultivar for Tokat red pepper tarhana was Gökkan cv, and the most favorable drying technique was open air drying. In addition, it is understood from the results that wheat cultivar and drying technique which used in tarhana production were essential factors. So, tarhana sector should choose the best wheat cultivar and drying technique to be used in tarhana production for consumer taste and healthy diet. From this study, it is understood that the open air drying is the most sustainable technique in terms of both production and consumption.","PeriodicalId":13814,"journal":{"name":"International Journal of Agriculture, Environment and Food Sciences","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135887001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
