The work aims to provide theoretical basis for the innovation, development and application of the compound material of cinnamaldehyde (CA). The main compound technology, application fields and specific effects of CA composites at home and abroad were reviewed, and some existing problems were analyzed. Meanwhile, the development trend of CA composites was also envisioned. CA composite was mainly used in food packaging and medical treatment because of its excellent antibacterial and antioxidant effect. Mostly, it was applied in food fresh-keeping package. Therefore, it was short of researches on the application in other aspects. As the research of the CA composite materials is newly started, and the process and application are still relatively simple, the research on new types of CA composite materials with more functions and the development of their application in other fields will be the future development trend of CA composite materials.
