Abstract

A total of 30 pork loin sections were utilized to evaluate the effects of FIR ceramic sheet in PE and vacuum package on preserving the quality of chilled pork stored at 4 and $0^{\circ}C$. Based on meat color, results indicated that pork loin packaged in ceramic sheet and control treatment showed that the samples of the control treatment tended to darken gradually in comparison with the samples at 0 day, but FIR treatment had few changes. Among the total plate counts of sliced loin in PE and loin in vacuum package under different storage times at 4 and $0^{\circ}C$, results showed that FIR ceramic sheet package treatment had lower total plate counts and significant differences (p<0.05). In VBN value, both treatments tended to rise high with the increasing of storage time, but the FIR treatment was significantly lower (p<0.05) than the control treatment. Its results had a corresponding relationship with the total plate counts. Regarding the drip loss of sliced loin in PE and loin in vacuum package, it showed that FIR ceramic sheet package treatment had lower drip loss and significant differences (p<0.01). These results showed that the use of FIR ceramic sheet package, including PE and vacuum package, is an effective method of maintaining the quality of meat.
