Sunset yellow is a synthetic azo colorant widely used in food and beverages. Excessive consumption of sunset yellow can lead to health risks, so it is necessary to establish an efficient and low-cost test. Electrochemical sensor has become a potential analytical method because of its high sensitivity and rapidity. Due to the rapid development of materials science, the detection limit of electrochemical sensors has been further reduced. In this work, we use two bibliometrics software to analyze the topic of electrochemical detection of sunset yellow. A total of 194 papers participated in the bibliometrics analysis. The country, institution and year in which the paper was published were analyzed to understand the cooperation model and development history of the topic. At the same time, this work also analyzes the keywords and categories of the paper. The research directions and hot spots in different stages of this topic are discussed. Finally, we summarized and proposed perspectives of this topic through bibliometrics results.
Keywords: Azo dye; Bibliometrics; Cooperative network; Electrochemical sensor; Nanomaterials; Sunset yellow.
