Active packaging is extensively developed as a promising concept to protect food products while maintaining its quality. Plant extract from papaya leaves has long been known to have antimicrobial and antioxidant activities due to the presence of phenolics and other compounds such as alkaloids, flavonoids, saponin and tannin. Extraction method, solvent type, sample preparation, extraction time and extraction temperature play important roles in extracting these bioactive compounds. The presence of bioactive compounds in papaya leaves extract gives it potentials to be developed into active packaging systems such as biodegradable active packaging or even edible active coatings. In the present review, the roles of bioactive compounds of papaya leaves as an antimicrobial and antioxidant agent are elucidated including their extraction process. In addition, the applications and opportunities of papaya leaves extract as an active substance in the food packaging field are also described.
