Food safety is directly related to human survival and development. The analysis and detection of food is an important way to ensure food safety. The traditional food detection mainly relies on the professional instrumentation and operation, which is expensive and time consuming. So it has great practical significance to find a simple, fast and popular method for food detection. As a simple, efficient and low-cost detection method, paper based microfluidic chip technology can realize miniaturization, automation, integration and portability from sample processing to detection, and show strong development activity in the field of rapid detection. This paper reviewed a series of important advances in the field of food detection by paper based microfluidic chip technology, such as food ingredients, pesticide residues, heavy metals, pathogens and food additives, and prospected its application prospect in the field of food analysis.
