Abstract
AbstractFoodborne harmful bacteria not only cause waste of fresh food, but also pose a major threat to human health. Among many new sterilization and preservation technologies, photodynamic inactivation (PDI) has the advantages of low‐cost, broad‐spectrum, energy‐saving, nontoxic, and high efficiency. In particular, PDI based on edible photosensitizers (PSs) has a broader application prospect due to edible, accessible, and renewable features, it also can maximize the retention of the nutritional characteristics and sensory quality of the food. Therefore, it is meaningful and necessary to review edible PSs and edible PSs‐mediated PDI, which can help to arouse interest and concern and promote the further development of edible PSs‐mediated PDI in the future field of nonthermally sterilized food preservation. Herein, the classification and modification of edible PSs, PS‐mediated in vivo and PS‐mediated in vitro mechanism of PDI, strengthening strategy to improve PDI efficiency by the structure change synergistic and multitechnical means, as well as the application in fresh food preservation were reviewed systematically. Finally, the deficiency and possible future perspectives of edible PSs‐mediated PDI were articulated. This review aimed to provide new perspective for the future food preservation and microbial control.
