In this study we have determined the contents of macroelements (Na, K, Ca, Mg and P) and microelements (Fe, Cu, Zn, Mn and B) in papaya samples (Carica papaya) obtained and consumed on the island of Tenerife, Canary Islands. The analysis shows the existence of significant differences in mineral content in the papaya samples. The papaya coming from MercaTenerife (wholesaler) presents higher K, P and Mn concentration levels than the papaya coming from the South Area of Tenerife. On the other hand, Na concentration levels are higher in the samples coming from the South Area of the island. There are differences between the mineral contents of this fruit shown in some food composition data tables and those analyzed in this work. The former are lower in Na, K, Ca and higher in Fe. In the same way, it is appreciated that the levels of Na concentration found in this work are greater than those found by other authors, and lower in Fe. When we compare the results obtained in this work and the recommended daily intakes or daily estimated demands of mineral elements proposed by different institutions or authors we realize that papaya is an important source of certain mineral elements, mainly K, Mg and B.
