CHANGES IN THE TRACE-ELEMENTS CONTENT DURING PULPING OF FRUITS IN DIFFERENT MIXIES

Grape, apple, pineapple and tomato were pulped in 9 brands of popular mixies and the quantum of Fe, Ni, Zn and Cr picked up by the juices wa s estimated. The increases in Fe, Ni and Zn contents of the fruit juic es varied differently, when pulped in different mixies. Chromium was n ot found either in the control juice or in the juices after pulping in different mixies. The Fe uptake by the fruit juices was positively co rrelated with increasing acidity, whereas, in case of Ni and Zn, the u ptake was negatively correlated with acidity.
