Infancy is the period of the life in which nutritional demands are the highest, since weight triples and length doubles during the first year of life (1). Due to the rapid growth rate, high amounts of Ca and P are needed to maintain optimal bone development (2). The mineral matrix of fish bone has higher concentrations of both elements than the edible part and can be used to improve the content of these mineral in some infants foods. The aim of the present study was to ascertain the addition of fish bone in the Ca and P contents and in their in vitro availability in three fish-based homogenised infant beikosts. The main difference among these samples was the inclusion or not of fish bones. The beikosts investigated were: sole beikost without bone (SB), sole beikost with bone (SBB) and sole and hake beikost with bone (SHB). We also evaluated the content and in vitro availability of other minerals (Fe, Zn, and Mg) to have a better knowledge of the nutritional value of these beikosts
