It examines the socio-cultural significance of food consumption, production, and distribution in shaping identities, social structures, and community relationships. Through case studies and ethnographic research, it explores how food serves as a lens for understanding issues such as globalization, colonial legacies, and cultural hybridity, highlighting how food culture intersects with broader socio-political dynamics on the continent. Culinary Narratives: Exploring the Socio-Cultural Dynamics of Food Culture in Africa Culinary narratives in African literature provide a unique lens through which to explore the socio-cultural dynamics of food culture on the continent. This review delves into the rich tapestry of food-related stories, traditions, and practices in African societies, highlighting their significance in shaping identity, community, and cultural exchange. This study examines the role of culinary narratives in African literature, focusing on how food-related stories and traditions reflect and influence socio-cultural dynamics. By analyzing a range of literary works from different African countries and regions, this study aims to uncover the diverse ways in which food culture is represented and its impact on African societies. Studying culinary narratives in African literature is crucial for understanding the complexities of food culture and its role in shaping identity and social relations. Food is not just sustenance in African societies; it is a form of communication, a marker of identity, and a medium through which cultural traditions are preserved and shared. By exploring culinary narratives, we gain insights into the values, beliefs, and traditions that define African cultures. This study argues that culinary narratives in African literature offer a rich and multifaceted portrayal of food culture, highlighting its significance in shaping identity, community, and cultural exchange. Through the analysis of various literary works, this study seeks to illuminate the diverse ways in which food is represented and its impact on African societies. In conclusion, culinary narratives in African literature offer a unique and insightful perspective on the socio-cultural dynamics of food culture on the continent. By exploring these narratives, we gain a deeper understanding of the diverse ways in which food is used to communicate, celebrate, and preserve cultural heritage in African societies.","PeriodicalId":499957,"journal":{"name":"Open access research journal of science and technology","volume":"3 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141795573","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 reason, it becomes highly essential to create more in the shortest amount of time in order to keep up with the always-rising demand. As a result, there has been a significant chance that these fruits may become contaminated with harmful microbes, raising concerns about consumer safety. This study sought to ascertain the potential health effects of fruit contamination by fungal species found on the fruit surfaces, as there is currently insufficient information in this area. Three (3) species of Citrus (CF) which include; lemon (Citrus limon (L.) Burm. f.), Chinese orange or sweet orange (Citrus sinensis (L.) Osbeck), and key lime or lime (Citrus aurantifolia (Christm.) Swingle) were randomly bought from different hawkers at different parts of Bwari market in Abuja, Nigeria. From the studies, five different fungal species were identified and they include: Penicillium spp Trichophyton spp, Aspergillus spp, Candida spp and Rhizopus spp. This demonstrated that fungi exist in all environments and that handling fruits improperly can have serious negative health impacts on people since some of these fungi are pathogenic. A number of approaches, such as washing fruits in vinegar water, have been found to be very effective in reducing microbial infection. Other washing methods, such as using saltwater, also work well. Additionally, it is a good idea to regularly replace the water used to wash those fruits in order to prevent cross-contamination while handling.","PeriodicalId":499957,"journal":{"name":"Open access research journal of science and technology","volume":"2 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141795980","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}
