The food industry has significantly expanded and become globalized due to the growth of the economies of many countries and an increasing world population. The industry is consequently facing major sustainability challenges. Food, which is critical to the existence of humanity and is affected by the world’s ecosystems and human intervention, is a fundamental issue within academic research, especially in terms of sustainability. Using a bibliometric approach, this paper analyzed studies on sustainability in the food industry in the context of the most cited articles, trends in the number of articles, most influential journals, most influential authors, most productive and influential institutions and countries, and future research directions. The software tools Bibliometrix 3.1.4 R-package and VOSviewer 1.6.18.0 were used together to analyze the dataset, which was obtained from the Web of Science database. The results indicated that Sustainability, Journal of Cleaner Production, and Frontiers in Sustainable Food Systems are the most important journals in this field, with the greatest number of articles published. Analyses of the network and overlay visualization of keyword co-occurrences identified six different research clusters. Since climate change and food security issues are in alignment with each other, sustainable food chains and social aspects are an important cross-cutting area of research. The results showed that future research should be multi-disciplinary and involve adjacent fields, including agriculture, agroecology, and climate science. There is also a need for research in the field of economic and social sustainability in the food industry. Studying the research topics found in the thematic map analysis, such as the effect of a sustainable diet on the food chain and the relationships among the agri-food system, sustainable agriculture, sustainable food systems, and sustainability of the food chain, is recommended for future research.

E-commerce and tourism have all seen a lot of growth and development recently in both business and academia. The tourism sector has significantly changed because of the growth of e-commerce platforms, as more and more consumers buy their rooms and tickets online. The academics conducted further research to understand the impact of e-commerce platforms on the tourism industry, leading to the development of these two specific fields’ body of literature. A bibliometric review was carried out to draw the trends of the research conducted to date in the field of e-commerce and tourism. Thus, it is possible to have a general overview of the literature for academics to intent to conducting future research. Employing bibliometric analysis with Biblimetrix software on 456 publications from the Web of Science database covering the years from 2000 to 2022, this study identifies predominant themes and research trends in the field. The terms “e-commerce” and “tourism” were used as keywords. During the analysis, six research questions were answered and results were combined with Resource Dependence Theory. Australia and China which are the first two countries in terms of citations. China is the outstanding country for author collaborations. Co-citation network analysis identified four clusters, namely management, model, satisfaction, and quality. Publications with keyword “communication”, “enterprises”, “application” and “rural” are in a decrease after 2015. Finally, future research directions were proposed.

Education quality and tourism faculties have a crucial role as qualified personnel is essential in the tourism industry; however, few studies have investigated this field using the bibliometric visualization method. The main aim of this study is to understand the trends in scientific publications about "education quality" and "tourism faculties" and how authors, institutions, and countries interact in these studies. To be able to understand that bibliometric methods within scientometrics were used via Citespace to merge two terms from 2002 to 2021. Data were obtained from the WoS database in January 2022. After the extraction process, a total of 711 publications were found that were linked to education quality and tourism faculties, and a set of co-occurrence, co-cited, and high-frequency word analyses were used. Basic 5 conclusions are derived based on the analysis method. When the five conclusions are examined, the methodology of this study, which is new for educational sciences and tourism, will contribute to the increase of knowledge and epistemology cumulatively in the field. Also, it will lead to the emergence of more publications on related subjects by directing the researchers to the less studied areas. And additional scholarly collaborations may be able to improve the depth of this research.
