Since Twitter covers a broad spectrum of topics, this study aimed to evaluate the consumer perception of an agri-food product using its data as source of information. The keyword "eggs" was searched in different languages (English, French, Spanish, and Portuguese) and a content analysis was performed in tweets that had terms referring to the product in a food context. Although most of the perceptions regarding the use/consumption of eggs were shared among the languages, some differences could be highlighted such as the period of consumption of eggs or important concerns related to the product, such as quality, animal welfare, special diets, and price. In conclusion, we can highlight the use of Twitter as a practical source of information about consumers' perception of eggs and a dynamic tool to guide the different agents in the egg production chain. These findings can drive improvements both in zootechnical procedures (such as the way chickens were raised, feed formulation, egg processing, etc.), egg quality assurance, as well as identifying global or targeted trends in the poultry sector. Practical Application Social media has emerged as an important tool to obtain market and consumption trends around the world, attracting special attention from academics and scientists in the consumer research area. Among them, Twitter stands out, which is easy to use and a pertinent crowdsourcing platform for acquire spontaneous information elicited in real-life situations. This is the first multilingual study available for the public on consumer's trends on eggs using Twitter and we believe that can be used by producers and traders in the egg production chain to improve production variables and quality parameters, as well as to invest in marketing strategies that are global or targeted at the different segments of egg consumers. 1 | INTRODUCTION Eggs have always been recognized as an excellent source of highquality proteins with bioactive proteins and other essential nutrients as minerals and vitamins. In addition, it provides many desirable technological properties such as foaming, emulsifying, gelling, coloring and flavoring, being used in various processed food products (Guha,
Social media has experienced rapid growth in recent years and has been subjected of discussions on a wide range of topics including new lifestyles and eating habits, providing a great opportunity to obtain spontaneous consumer information. In this sense, the present work aimed to understand the perception of Twitter Ò users about themes of veganism and plant-based diets. The social networking data mining methodology was applied to measure the relationship between both terms. The significant differences found were analysed using the global chi-square (v 2) test, and their sources of variation were investigated by the chi-square per cell. The results indicate that the vegan group's posts are more related to the categories of recipes, trends, criticism and negative comments about veganism, being more often citing sources when compared to the other group. The results of the plant-based diet group are more significantly related to the impacts of nutrition, physical activity and consumer health. In conclusion, Twitter Ò has proved to be an interesting tool for obtaining data on (re) produced food publications on social media and their results can guide the market and the academic environment in creating new products, services and marketing strategies to answer the needs of specific consumers.
Industrial livestock production presents a growing problem on a global scale in terms of animal welfare, environmental sustainability, and human health. One solution might be cultured meat, in which animal tissue is grown in a controlled environment using cell culture technology, thereby making the raising and killing of animals for food unnecessary. This approach shows great potential of meeting all the requirements of a humane, sustainable and healthy form of meat production. However, a great deal of scientific, technical, cultural and legislative challenges must be overcome before cultured meat can reach costcompetitiveness. Lack of funding is the main barrier to further development, and considerable upfront investment is needed for cultured meat to attain commercially viable retail prices. We therefore strongly support increased funding of cultured meat initiatives. This entails, in order of priority: research and development of technology suitable for mass production, promoting fact-based public discussion regarding the technology and its societal implications, and eventual marketing of end products to consumers.
Open access journals have gathered increasing prominence as researchers understand the importance of communicating their research to the general public and not just to the scientificcommunity. Journals such as Páginas a&b: arquivos e bibliotecas(Portugal) and Perspectivas da Ciência da Informação(Brazil) are good examples of this type of publication in the area of Information Science. In this sense, this study contributes with a bibliometric and comparative analysis of suchpublications between 2016-2020, in order to trace a trend profile based on them. In short, the themes divergefrom management to the Information-Documentation professionals' technical issues.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
