A Comprehensive Review on Papaya Phytochemistry Profile, Bioaccessibility, Pharmacological Effects and Future Trends of Papaya Phytochemicals

Abstract

ABSTRACT Papaya is one of the most consumed fruits around the world, which possesses low energy and is very suitable for those trying to reduce weight. Papaya is packed with a bunch of vitamins, minerals, as well as phenolic compounds. Phytochemicals have beneficial effects on the human body, including anti-cancer, anti-diabetic, and anti-dengue activities. Numerous studies have estimated nutritional and medicinal properties. The study of the bioaccessibility of papaya chemicals is important for both the food and medicine industries. This review summarizes the nutritional value and phytochemical content of different parts of papaya. Influencing factors like pre- and post-harvest on phytochemical content also have been reviewed. Further, the bioaccessibility and bioavailability of phytochemicals as well as the medicinal properties, based on the in vitro and in vivo studies are deeply reviewed. Finally, the research progress, gaps and interesting future aspects of papaya phytochemicals have been discussed. These phytochemical compounds are influenced by numerous factors, such as pre- and post-harvest, as well as extraction conditions. Many factors may affect the bioaccessibility and bioavailability of these phytochemicals, but there is limited information. Therefore, further studies like in vitro and in vivo experiments should be conducted to authenticate the efficiency of the papaya plant.
