A review of the postharvest biochemical, biophysical and biological properties of 61 cultivars of North American pawpaw (Asimina triloba) fruit

Fruit from the North American pawpaw (Asimina triloba) is unfamiliar to many as a food crop and botanically unusual because it is the northernmost genus and only temperate member of the tropical Annonaceae family. It is the largest edible fruit native to North America. Wild or unnamed cultivars of pawpaw account for much of the pawpaw that is sold in the United States, however, there are over 160 named cultivars of pawpaw. Only a few hundred papers accounts for the entirety of the published research on pawpaw, and the majority of that research is focused on preharvest growth characteristics. Manuscripts that exist about biochemical, biological, and biophysical properties of pawpaw tend to not identify the cultivars that were assayed. This review presents an overview of biochemical, biological, and biophysical properties of named cultivars of the North American pawpaw (Asimina triloba). Sixty-one named pawpaw cultivars were analyzed and compared. The biochemical, biological, and biophysical properties reported in this study provide a strong basis to the view the pawpaw through a wider lens that could lead to breakthroughs in the development of new food products, functional insights, and processing technologies. Understanding the differences in quality attributes between pawpaw cultivars can aid in improving this underutilized fruit crop.
