Evaluation of the effect of freezing milk samples on the refractive index for copper(II) serum determination
This work aimed to evaluate the effect of freezing of raw and whole UHT milk samples on the refractive index for copper(II) serum (RICS) determination. Eighteen samples were used in this study (9 raw and 9 whole UHT milk samples). RICS values were determined before and after freezing on different da...
