Sažetak
The toxic elements content is an important determinant of food safety . Naturally present geogenic originated amounts of heavy metals and toxic compounds in soil increase permanently through soil contamination from antropoghenic sources such as emmision of industry, land and air traffic, mineral fertilizers, plant preservatives and additionally in war time conditions by explosions of different kind of ammunitions. Because of their significant toxic impact, even in low concentrations, a constant monitoring of water, soil, air and food is necessary, especially in the areas with permanent potential risk. Cereals and cereal-based products are main sources of carbohydrates that is energy in nutrition, being thereby depending on the milling rate rich sources of protein, vitamins, minerals and fiber in diet, too. In our previous examinations we found cereal based confectionary products could be considered as a good aditional source of essential trace elements Zn, Cu, Fe and Mn, depending on the type of raw material used. Since they are consumed throughout whole human life, especially by children and old people, it is of interest to know if such products could be a source of toxic or potentially toxic elements in diet, too. To evaluate different kind of hard biscuits in regard to toxic elements (Pb, Cd) and potentially toxic elements (Cr, Ni , Sr) contents, three production series of different classic white wheat flour based hard biscuits and biscuits enriched with whole grain wheat flour and/or whole grain wheat grits, skimmed milk. honey and soya flour were analysed. Lead, cadmium, chromium, nickel and strontium concentrations were determinated by ICPAES on the Trace Scan Sequential ICP Plasma spectrometer, Thermo Jarrell ash. Homogenized samples were digested in Microwave Digestion Unit, MLS – 1200 MEGA. Data reveal Pb content ranges from 0 up to 0.25 mg/kg, Cd 0-0.10 mg/kg, Ni 0-0.71 mg/kg, Cr 0-0.09 mg/kg and Sr 0.19-0.79 mg/kg, respectively. Analysis show enriched biscuits were higher in all investigated elements. With regard to the maximal concentration of lead and cadmium all the investigated biscuits met the standard of the Public Health Regulation in Croatia, which allowed up to 0.4 mg Pb/kg and up to 0.1 mg Cd/kg of cereals and cereals products.
