Thermal treatments applied to infant foods are critically important to guarantee
microbiological safety. However, loss of nutrients linked to heating processes must be
avoided to maintain the nutritional properties. Since baby purees together with infant
formulas or breast milk are the only food sources for babies, it is very important that
this type of food has an adequate nutritional quality to support a satisfactory nutritional status and a normal growth rate (Hernández Rodríguez, 2001). Due to the advantages
linked with ohmic heating, it might be an alternative heating method to achieve the
sterilization of baby products.
