Lactic acid bacteria in wheat fermentation: A bibliometric analysis of antioxidant peptide production

The increasing demand for functional foods has led to an interest in fermentation processes that enhance the production of antioxidant peptides. This study aimed to perform a bibliometric analysis of lactic acid bacteria (LAB) used in the fermentation of wheat to produce antioxidant peptides. To achieve this, data from 2010 to 2023 were gathered from the Web of Science® database, focusing on publications related to LAB, wheat proteins, and antioxidant peptides. The search results were analyzed using the bibliometrix R package, which allowed for an in-depth examination of research trends, collaborations, and influential studies. Results indicated increased research activity, with an average annual growth rate of 13.18% and contributions from countries such as China and Italy. The primary focus areas included fermentation methods, peptide production, and health-related applications of bioactive compounds. Collaboration networks highlighted the importance of international partnerships in advancing this field. The results provided insights into the development and application of LAB in food science, emphasizing the potential of bioactive peptides produced from wheat in promoting health through antioxidant activity. This study contributes to understanding the research landscape and the future potential of using LAB to produce functional food ingredients.
