Abstract
[Objective] To address the problem of browning and oxidation in meat products processed from frozen lamb during shelf life. [Methods] Frozen sliced lamb ribs during temperature elevation were treated with an electrostatic field and then packaged using modified atmosphere packaging with different gas compositions. The samples were stored at 10 ℃ after packaging, and meat color, total viable count, oxidation level, and antioxidant enzyme activity were measured at 0,48,72, and 96 h of storage. [Results] After treatment with a 25 kV electrostatic field for 30 min, samples packaged under high -oxygen conditions (70% O2+30% CO2, EO group ) showed significantly lower browning rate and slower increase in total viable count compared to the high -oxygen packaging group without electrostatic field treatment (O group ). At 48 h of storage, the a* value of the EO group was 1.55 times that of the O group, while the mean total viable count was 0.95 lg (CFU/g ) lower than that of the O group. The EO group exhibited significantly higher antioxidant enzyme activity and protein sulfhydryl content, while lactate dehydrogenase activity was significantly lower than that of the O group. [Conclusion] Electrostatic field treatment of partially thawed sliced lamb ribs effectively delays the increase in meat color browning, oxidation level, and total viable count in lamb ribs packaged under high -oxygen modified atmosphere conditions.
