MINERAL-CONTENT IN PASTEURIZED MILK PRODU CED IN THE ANDALUSIAN COMMUNITY

The Contents of copper, iron, zinc, manganese, calcium, magnesium, sod ium and potassium were determined by atomic absorption spectrophotomet ry in 300 samples of pasteurized milk from 10 milk factories belonging to 6 provinces of the Andalusian Community. The mean content was 0.14 mg/kg for copper, 0.40 mg/kg for iron, 3.82 mg/kg for zinc, 0.022 mg/ kg for manganese, 1.28 g/kg for calcium, 0.11 g/kg for magnesium, 0.56 g/kg for sodium and 1.78 g/kg for potassium. The variance analysis sh owed the existence of statistically significant differences (p < 0.001 ) in the content of all the element among factories. Scheffe homogenei ty test (p < 0.05) was used but the groups formed did not show any sta ndard distribution. The correlation matrix between the elements was us ed as a starting matrix for the factorial analysis of the relation bet ween the mineral elements in the pasteurized milk, and showed a high r elation between calcium, magnesium and zinc.
