(excerpt)
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.
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.
