Abstract

Abstract In this study, chiffon cakes were fortified with potato flakes and raw dehydrated potato flour (RDPF) prepared by freeze-drying and hot air drying. The dough’s rheological properties demonstrate that potato flakes are unsuitable for making chiffon cakes, especially at percentages of 30 and 50%. Adding RDPFs decreased the dough height and adhesiveness but increased the hardness slightly compared with the control. Supplementing with potato flakes has the most influence on cake textural properties, especially at percentages of 30 and 50%, which correspondingly reduces the sensory evaluation score. All the RDPF cake formulations exhibited higher comprehensive nutritional value in terms of protein, fat, dietary fiber, minerals, and amino acids. The cake formulations containing RDPF obtained by hot air drying contained the lowest carbohydrate contents.
