Summary:
The Andean tomato (Solanum betacea) and golden berry or cape gooseberry (Physalis peruviana) are characterized by their content of vitamins A, B and C, minerals (potassium and phosphorus respectively) and more importantly, of antioxidant compounds, highly demanded by current consumption trends, i.e. functional foods. On the other hand, pineapple (Ananas comosus) is characterized by its contents of vitamins A and C, and potassium.
The big problem with these foods is the short shelf life they have once harvested, due to their high free water content. Dehydration is one of the oldest food preservation techniques, in this sense it is intended to evaluate the technical applicability of foam drying in obtaining dehydrated pulps of these fruits. This technique allows to shorten processing times, which translates into greater production capacity, with lower energy consumption. In addition, it allows to obtain a product of easy reconstitution, with a great retention of aromas and phytonutrients.
