Abstract

American chestnuts (Castanea dentata) and Chinese chestnuts (C. mollissima) grown in the United States and imported European (Italian) chestnuts (C. sativa) were analyzed for proximate, mineral, and amino acid composition. Unlike most other tree nuts, chestnuts are low in protein and fat but high in carbohydrate. American and Chinese chestnuts were higher than European chestnuts for protein, ash, crude fiber, iron, magnesium, phosphorus, and copper but lower in fat. Essential amino acid patterns of chestnuts, as measured by chemical scoring, were about the same for American, Chinese, and European chestnuts.
