Sažetak
Cereal based confectionery products being consumed through whole human life are considered mainly to be a source of carbohydrates, that is energy, although cereals are rich source of minerals as well. To evaluate some hard biscuits produced in Croatia as a source of different trace elements in nutrition, in this study Zn and Cu contents were determined in classic wheat flour biscuits and in dietetic biscuits enriched with whole wheat grain flour or whole wheat grain grits, soya flour and skimmed milk. Zn was determined by atomic absorption spectrometry (AAS) ; Cu was determined by inductively coupled plasma atomic emission spectroscopy (ICP - AES). The results show that Zn content in different kinds of biscuits ranges from 5.89 up to 17.64 mg/kg and Cu content ranges from 1.15 up to 2.79 mg/kg depending on the type of wheat milling products and mineral content of other ingredients used. Enriched dietetic biscuits produced from wheat flour type 850 and whole wheat grain flour and/or soya flour and skimmed milk were almost 200% and 150% higher in Zn and Cu, respectively, in comparison to classic white wheat flour biscuits and can be considered as good sources of Zn and Cu in nutrition.
