The color of meat was concurrently assessed at the same time by Konica Minolta CM-3500d device. The results were evaluated by CMs-100w Spectramagic NX, indicate values of CIE L*a*b*. The methods of packaging greatly influenced durability dependent on the development of contaminating microflora and color of meat.
