Analysis of metal ions as soluble salts in different dairy products

Abstract

Milk and dairy products are unique combinations of micronutrients with multiple recognized health benefits. The trace elements present in dairy products have an important role in living organisms, among the most important being Fe, Mn and Co. Through this work we performed the analysis of the content in soluble salts of some metals in several dairy products on the market regarding the content of nitrites, phosphates, chlorides and ions of iron, manganese and cobalt. Following the analyzes, a higher iron content was observed in the products Lapte de consum Vreau din România with 3,5% fat (18.36 mg/Kg) and Actimel Danone de căpşuni with 1,5% fat (15.44 mg/Kg), higher values for manganese ions in products Danonino brânzică de zmeură with 2,5% fat (84.56 mg/Kg) and Danonino brânzică de banane with 2,5% fat (96.57 mg/Kg) and higher values for the cobalt content of drinking yogurt products (Iaurt de băut Vreau din România with 2% fat - 0.06097 mg/Kg, Iaurt natural de băut Zuzu with 2% fat - 0.0663 mg/Kg, Iaurt de băut Pilos with 2% fat - 0.07697 mg/Kg).
