Popis: A β-carotene and iron rich snack was developed aimed at children consumption. β-carotene was added to the snacks, in the flavoring mixture after (A) or before (B) extrusion. Proximate composition, β-carotene content, instrumental color and texture parameters were determined during storage. Both products had low content of lipids and high content of bioavailable iron, β-carotene and proteins. Shear resistance of snack B increased during storage, and the values of B were greater than those of snack A. The color parameter a measured on snack B was greater than the verified for snack A, whereas the opposite was observed for parameter b. Initial β-carotene content was higher in the snack A with significant reduction in both snacks during storage. β-carotene reduction from 15 to 60 days was less pronounced in the snack A as compared to snack B. The flavoring and fortification methods affected the shear strength, color parameters and β-carotene contents of the snacks.
