Abstract

This study was conducted to investigate the influence of dietary sardine oil on storage and processing characteristics in meat sample of chicken meat. Broilers were randomly assigned to one of four dietary treatments: 1) Control(commercial feed) 2) T1(commercial feed supplemented with 1% sardine oil) 3) T2(commercial feed with 2% sardine oil) and 4) T3(commercial feed with 4% sardine oil). They were fed one of the experimental diets for five weeks and slaughtered. After that, the meat samples were vacuum packaged and stored at 4$\pm$1$\^{C}$. The storage and processing characteristics were analyzed for meat samples stored over a period of 0, 1, 3, 7 and 10 days. The pH of all treatments significantly increased during the storage periods (p<0.05). The TBARS(thiobarbituric acid reactive substances) af all treatments were significantly increased as storage period extended (p<0.05). After 1 days, the TBARS of treatment groups were significantly higher than that of the control (p<0.05). The T3 showed the highest TBARS among all treatments (p<0.05). The VBN(volatile basic nitrogen) of all treatments significantly increased during storage period (p<0.05). However, the VBN was not significantly different between control and treatment groups. The WHC(water holding capacity) and heating loss were significantly increased in both control and treatment groups during storage (p<0.05) and however, WHC was not significantly different among 3 treatment. The heating loss tended to increase in treatment groups compared to the control.
