Pawpaw Description and Nutritional Information Kentucky State University Cooperative Extension Program Pawpaw Research Project, Community Research Service, Atwood Research Facility, Frankfort, KY 40601-2355 From The KYSU Extension Bulletin, "Cooking with Pawpaws" by Snake C. Jones and Desmond R. Layne Go to Nutritional Information Pawpaw Description The pawpaw is the largest edible fruit that is native to the United States. Pawpaws are indigenous to 26 states in the U.S., in a range extending from northern Florida to southern Ontario and as far west as eastern Nebraska. They have provided delicious and nutritious food for Native Americans, European explorers and settlers, and wild animals. They are still being enjoyed in modern America, chiefly in rural areas. There are 27 varieties (Table 1) currently available from more than 50 commercial nurseries in the U.S. Most enthusiasts agree that the best way to enjoy pawpaws is to eat them raw, outdoors, picked from the tree when they are perfectly ripe. But there are also numerous ways to use them in the kitchen and extend the enjoyment of their tropical flavor beyond the end of the harvest season. The unique flavor of the fruit resembles a blend of various tropical flavors, including banana, pineapple, and mango. The flavor and custard-like texture make pawpaws a good substitute for bananas in almost any recipe. The common names, ‘poor man’s banana,’ ‘American custard apple,’ and ‘Kentucky banana’ reflect these qualities. Pawpaw’s beautiful, maroon colored flowers appear in the spring, and the clusters of fruit ripen in the fall. The Kentucky harvest season is from late August to mid-October. Ripe pawpaw fruits are easily picked, yielding to a gentle tug. Shaking the tree will make them fall off. (If you try this, don’t stand under the fruit clusters, and don’t say we didn’t warn you.) Ripeness can also be gauged by squeezing gently, as you would judge a peach. The flesh should be soft, and the fruit should have a strong, pleasant aroma. The skin color of ripe fruit on the tree ranges from green to yellow, and dark flecks may appear, as on bananas. The skin of picked or fallen fruit may darken to brown or black. Fully ripe pawpaws last only a few days at room temperature, but may be kept for a week in the refrigerator. If fruit is refrigerated before it is fully ripe, it can be kept for up to three weeks, and can then be allowed to finish ripening at room temperature. Ripe pawpaw flesh, with skin and seeds removed, can be pureed and frozen for later use. Some people even freeze whole fruits. Pawpaws are very nutritious fruits. They are high in vitamin C, magnesium, iron, copper, and manganese. They are a good source of potassium and several essential amino acids, and they also contain significant amounts of riboflavin, niacin, calcium, phosphorus, and zinc. Pawpaws contain these nutrients in amounts that are generally about the same as or greater than those found in bananas, apples, or oranges. Nutritional Information Composition In comparison with banana, apple, and orange, pawpaws have a higher protein and fat content. Banana exceeds pawpaw in food energy and carbohydrate content. There is little difference among these fruits in dietary fiber content. Pawpaw is most similar to banana in overall composition. Apple is especially low in protein, orange is low in fat, and both are lower than pawpaw or banana in food energy. See Table 2 and Table 3 for details. Vitamins Pawpaw has three times as much vitamin C as apple, twice as much as banana, and one third as much as orange. Pawpaw has six times as much riboflavin as apple, and twice as much as orange. Niacin content of pawpaw is twice as high as banana, fourteen times as high as apple, and four times as high as orange. See Table 2 and Table 3 for details. Minerals Pawpaw and banana are both high in potassium, having about twice as much as orange and three times as much as apple. Pawpaw has one and a half times as much calcium as orange, and about ten times as much as banana or apple. Pawpaw has two to seven times as much phosphorus, four to twenty times as much magnesium, twenty to seventy times as much iron, five to twenty times as much zinc, five to twelve times as much copper, and sixteen to one hundred times as much manganese, as do banana, apple, or orange. See Table 2 and Table 3 for details. Sodium content has not yet been determined. Amino acids The protein in pawpaw contains all of the essential amino acids. Pawpaw exceeds apple in all of the essential amino acids, and it exceeds or equals banana and orange in most of them. See Table 2 and Table 3 for details. Fats The profile of fatty acids in pawpaw is preferable to that in banana. Pawpaw has 32% saturated, 40% monounsaturated, and 28% polyunsaturated fatty acids. Banana has 52% saturated, 15% monounsaturated, and 34% polyunsaturated fatty acids. Table 1. Commercially Available Named Pawpaw Cultivars in the United States a
