The effect of Sole mince washing by chitosan solution on heavy metals removal and oxidation stability during refrigerator storage

In this study the effect of washing by chitosan solution were examined on the heavy metals removal from sole mince and oxidative stability during 15 days of refrigerated storage (4ºC). Treatments were included washing the mince with tap water (control), washing by 2% (treatment 1) and 5 % chitosan water solution (treatment 2). The lead content was reduced from 8.45 ppm in control samples to 0.48 and 0.21 ppm in treatments 1 and 2, respectively. Cadmium was not found in treatments 1 and 2. The nickel content was reduced from 1.54 ppm in control samples to 0.60 and 0.39 ppm in treatments 1 and 2, respectively. The PV and TBA content in treatments 1 and 2 were significantly (P
