Pyrroloquinoline quinone is a redox-active quinone molecule which is soluble in water. It exerts various biological functions by participating processes such as oxidation-reduction in the body and has been successively included in the lists of dietary supplements and functional food ingredients in many countries.Pyrroloquinoline quinone has been approved as a novel food ingredient, with permission for limited addition to beverage products in China. With the continuous deepening of research, it has broad application prospects in the field of health food. This article reviewed the recent research on the biological functions, safety toxicology and detection technologies of pyrroloquinoline quinone, classified the biological functions according to the catalogue of health functions permitted to be claimed by health food, provided insights into the research trends of biological functional mechanisms, functional evaluation indicators, safety and detection technologies, aiming to provide scientific evidence for the development of pyrroloquinoline quinone-related functional products, as well as for the registration,development, evaluation and supervision of health food which used pyrroloquinoline quinone as raw material.
