Is the use of biosensor in monitoring food quality experiencing an uplift trend over the last 30 years?: A bibliometric analysis

Recently, there has been intense competition among food industries worldwide as they strive to fulfill the ever-growing consumer expectations regarding both the quantity and quality of food. The increasing demand for high-quality food has motivated researchers and academics to constantly innovate and develop real-time and precise tools for monitoring food quality. One such tool that has emerged is biosensors, which have already been widely investigated; however, no bibliometric reviews have discussed biosensor use holistically, comprehensively, and objectively. Therefore, this review aimed to analyze the trend of biosensor publications for monitoring food quality based on the number of documents published from 1991 to 2021, analyze the contribution of various journals, institutions, and cooperation between countries, highlight the most influential authors and articles, and predict the development of this topic. The Method used in this study is bibliometric analysis which consists of four stages, namely data mining from the Scopus database which are limited to data for the last 30 years (1991–2021), refining data, data visualization and interpretation data. There are 604 articles obtained from Scopus and visualization shows that biosensor use for monitoring food quality has significantly increased in the past three decades. Biosensors and Bioelectronics is the leading journal in publishing manuscripts on the topic of biosensors. In terms of the largest contribution, China produced the highest number of publications on related topics, while the United States has the highest collaborations between countries. Moreover, Whitcombe MJ has the most influential articles, while Wang S had the largest number of outputs. The frequently used keywords are “biosensors,” “food safety,” and “food analysis.” These results are important references to determine the state of the art and directions for further investigations.
