In this study, the effects of intermittent storage temperature on physicochemical<br />

properties and microbial population of local frozen beef were investigated. The<br />

striploin beef samples were divided into 3 groups (C:-20°C, T1: 5°C, and T2: 10°C)<br />

and were packed in commercial air permeable film. All the samples were stored at -<br />

20°C for the first two days and then transferred to 5°C and 10°C respectively. The<br />

samples were kept for 0, 2, 4, 6, 8 and 10 days for analyses. Results showed that as<br />

the storage temperature was interrupted, the quality of frozen beef changed and the<br />

population of total aerobic and Pseudomonas sp. increased (p
