Nutritional evaluation of air potato (Dios- corea bulbifera L.) grown in Panamá. The goal of this study was to determine the nutritional composition of air potato (Dioscorea bulbifera L.) tubers, underutilized specie in the Panamanian peasant agriculture. The samples were obtained from test plots located in rural communities in the district of Donoso, Province of Colon in Panama, during the years 2012 and 2013. Contents of moisture, protein, sugars, starch, lipids, ashes and energetic were determined to the 18 selected samples. In the second year were included analysis of vitamin C, phenolic compounds and antioxidant activity. No significant differences of the values between communities, type of land and crop year were found, which suggest high stability of these nutritional values of air potato, in the very humid tropics conditions of Panama. The results show that the air potato tubers have a nutritional value similar to other tubers used in the peasant diet of Panama. The levels of antioxidant activity and phenolic content found, give D. bulbifera characteristics as a functional food.

Palabras clave : Underutilized crop; functional food; antioxidant; Panama.
