Polydiacetylene (PDAs) is a special semiconductor polymer with an alternating conjugated structure of ene-acetylene and unique optical and electronic properties. Typically, PDAs change from blue to red in response to the external stimuli, such as temperature, pH, ions, organic solvents, pressure, and donor-acceptor interactions. This colorimetric response of PDAs makes them one of the excellent materials for chemical or biosensor analysis platforms. In this review, we briefly describe the research progress of polydiacetylene systems in the field of food biotechnology. The challenges and outlooks of PDAs sensing materials in visual detection of preservatives in food innovatively were also discussed.
