An attempt was made to use expanded amaranth seeds, commercially available as Popping, in the production of Piccolino and Kruche biscuits, in order to replace 25 and 33% of fat (margarine) given in the recipe. The recipe modification made it possible to obtain new quality products with higher nutritional value, i.e. with higher protein, dietary fibre and mineral components contents, as compared with standard biscuits. Better consumer acceptance was observed for Piccolino biscuits. The analysis of solid fats extracted from the biscuits showed the three months’ shelf life of the products. Because of the higher Fe content – by about 50% as compared with traditional biscuits – the products with the addition of Popping can become a source of easily available iron in child’s diet.
