Sažetak
A two-year study of raw, pasteurized and sterilized milk was conducted. Spectrophotometric method for determination copper content in all milk samples was used. Samples for analysis were taken from the milk collecting stations of the nortwest Croatia as well as from milk transportation tank of the same area. Pasteurized and sterilized milk samples from market were analyzed too. The results of 288 analyzed samples have shown that the minimum copper content was 1-42 and the maximum 12.93 μg/100 ml. Analysis of variance showed that there was no significant difference between copper content in raw, pasteurized and sterilized milk samples, but there was significant seasonal influence on the copper content in milk. Greater copper content w-as found in the period from November to March and less in the period from April to October.
