Abstract
The objective of this study was to investigate the effect of chitosan and modified atmosphere
packaging (MAP) on color changes of Giant Perch during cold storage. Giant Perch meat added with
chitosan (5 mg /g fish), Giant Perch meat packed by MAP (O
2
10%, CO
2
80%, N
2
10%), Giant Perch meat
added with chitosan and MAP and control were prepared. Color (L* a* b*) changes were examined
during storage by using colorimeter. As the storage time increased, the highest change of color was
observed in control (P<0.05). The more stability of color was observed in the sample using chitosan
and MAP. However, the more color changes of all samples were found as the storage time increased
p<0.05). Consequently, chitosan could be used together with MAP in processing industry to retard the
color changes and prolong the shelf-life of Giant Perch meat.
